BBC NEWS | Talk about Newsnight | How green is your government Minister?

Worth going to the site for an intersting discussion on carbon neutral schemes:

BBC NEWS | Talk about Newsnight | How green is your government Minister?

The Government makes a lot of its new green credentials. Tony Blair and Gordon Brown jointly launched Sir Nicholas Stern’s report on the potentially apocalyptic consequences of global warming and, to underline the government’s commitment, it announced a climate change bill in the Queen’s speech.

Environment minister Ian Pearson MP on Newsnight in OctoberIndeed, back in May Mr Blair appointed a Minster with special responsibility for climate change. He is Ian Pearson, the MP for Dudley South, and yesterday I shared a platform with him at a conference on sustainable development.

It was my job to open the conference. I ran through some of the things my family and I have been doing as Ethical Man and then I set the delegates a little ethical living test. I asked a series of questions about their lifestyles including whether they had made the switch to a green electricity supplier.

It was one of the first things I did after I was coerced by my editor into becoming Ethical Man and it did more to cut the carbon footprint of our home that any of my other ethical exertions.

For a small premium, our new supplier guarantees that, for every unit of electricity we use, it will buy a unit of electricity from a renewable source. According to my carbon guru, Professor Tim Jackson of University of Surrey, switching supplier will cut the annual carbon emissions my family is responsible for by about one ton – that’s ten per cent of our total emissions.

This was a pretty green audience and a good few of them had signed up with green suppliers or had opted for one of the green tariffs offered by most electricity companies. So had the Minister done the same I wanted to know?

Imagine my surprise when Mr Pearson admitted he hadn’t. The Minister of State for Climate Change and the Environment said that he was in the process of doing so.

Given that changing to a green electricity supplier or opting for a green tariff takes a single telephone call and a couple of minutes I trust he has done so now. If not here are a few contacts for you Ian: you could see if your current electricity company offers a green tariff or could contact Good Energy, Ecotricity, Green Energy UK or any of the other green electricity companies in the country.

Oh, and do tell me how you get on.

ExxonMobil's view of the never-changing world

Fri, 12/15/2006 - 2:47pm.

For ExxonMobil, the world is rapidly changing, but somehow their business will stay exactly the same. What follows are facts gleaned from ExxonMobil’s The Outlook for Energy, A view to 2030 (PDF)

  • "Most of the world's growing energy needs by 2030 will continue to be met by oil, gas and coal." Today, 80% of the energy we use comes from fossil fuel. Exxon doesn't expect that number to change.
  • The world will require "about 60%" more energy in 2030 than it does today. That's a total consumption of 325 million barrels per day.
  • Non-OECD nations will account for 80% of that increase.
  • In 2000, non-OECD countries drove roughly 100 million cars. By 2030 they’ll drive 500 million.
  • If the world were not moving towards more efficient use of energy, our energy use in 2030 would be 100% higher than it is today. Good thing we're so efficient.
  • By 2030, wind and solar will only account for 1% of all energy produced.
  • By 2030, 30% of all new vehicles sold will be hybrids or other high-efficiency vehicles.
  • Biofuels will make up only 2% of all liquid fuels by 2030, Bio-Willie notwithstanding.
  • The USGS estimates there are around 3.2 trillion barrels of oil that can be extracted from the world. ExxonMobil sees around 4 trillion as economically recoverable.
  • Corn-based ethanol is a non-starter. By 2012, the U.S. will burn up 21% of the U.S. corn crop to create 3% of our fuel. Exxon chortles: "...this provides some perspective on its ultimate potential as an alternative fuel supply."
  • Cellulose is also too complicated to turn into fuel. The process involves enzymes and other things oil men find unfamiliar and strange. President Bush was foolish to tout the energy potential of switchgrass.
  • Natural gas will become more popular than any other fuel, and most of it will be used in power generation.
  • CO2 production will increase at exactly the same rate as energy consumption.
  • There are four opportunities to reduce carbon emissions: nuclear power, advanced vehicles and fuels, carbon capture, and "breakthroughs."
  • ExxonMobil helped establish (via a $100 million grant) Stanford Univeristy’s Global Climate and Energy Project. ExxonMobil hopes Stanford will provide some breakthroughs.

Οι ωκεανοί γίνονται ανησυχητικά πιο όξινοι

Ένα φαινόμενο που θυμίζει την όξινη βροχή των δεκαετιών του '70 και του '80 απειλεί τώρα τους ωκεανούς, προειδοποίησαν επιστήμονες στη διεθνή διάσκεψη για το κλίμα που πραγματοποιεί ο ΟΗΕ στην Κένυα. Η οξύτητα του νερού αυξάνεται λόγω του ατμοσφαιρικού διοξειδίου του άνθρακα.

Οι ωκεανοί έχουν ήδη απορροφήσει το ένα τρίτο της παγκόσμιας εκπομπής διοξειδίου του άνθρακα, του κυριότερου από τα αέρια που προκαλούν και το φαινόμενο του θερμοκηπίου. Η διάλυση του διοξειδίου στο νερό αυξάνει την οξύτητα ανησυχητικά τις τελευταίες δεκαετίες.
«Η αύξηση της οξύτητας των ωκεανών αποτελεί σημαντική απειλή για τους θαλάσσιους οργανισμούς» δήλωσε ο καθηγητής Στέφαν Ράμστορφ, επικεφαλής του Ινστιτούτου Έρευνας Κλιματικών Φαινομένων του Πότσνταμ στη Γερμανία.

Το φαινόμενο απειλεί να «αλλάξει ριζικά» τη διατροφική αλυσίδα επιδρώντας στους πληθυσμούς των ψαριών, προειδοποίησε ο Ράμστορφ. Ιδιαίτερα ευάλωτα είναι τα κοράλια, τα οποία δυσκολεύονται να συνθέσουν τον ασβεστολιθικό σκελετό τους κάτω από τόσο όξινες συνθήκες.

Ο Ράμστορφ επανέλαβε επίσης τις προειδοποιήσεις για άνοδο της στάθμης της θάλασσας. Σε διάστημα 70 ετών, περίπου 200 εκατ. άνθρωποι θα απειλούνται από πλημμύρες, ενώ τα ακραια καιρικά φαινόμενα θα έχουν γίνει συχνότερα.

Στη διάσκεψη του ΟΗΕ συμμετέχουν τα 189 κράτη που έχουν υπογράψει το Πρωτόκολλο του Κιότο κατά της κλιματικής αλλαγής, το οποίο προβλέπει μείωση της εκπομπής αερίων του θερμοκηπίου κατά 5%, σε σχέση με τα επίπεδα του 1990, μέχρι το 2012.

Στη συνάντηση του Ναϊρόμπι συζητείται το πλαίσιο εφαρμογής του Κιότο αλλά και τα μέτρα που θα πρέπει να ληφθούν μετά το 2012.

Βιομηχανίες ρύπανσης


Σχεδόν μία στις δύο επιχειρήσεις στη χώρα μας αδιαφορούν για τις επιπτώσεις που προκαλούν στο περιβάλλον.

Οι 145 επιθεωρήσεις που έκαναν την προηγούμενη χρονιά οι επιθεωρητές περιβάλλοντος του υπουργείου ΠΕΧΩΔΕ έδειξαν ότι το 42,9% των βιομηχανιών και άλλων εγκαταστάσεων δεν λαμβάνουν τα προβλεπόμενα μέτρα για την προστασία των γύρω περιοχών.

Μάλιστα οι παραβάσεις ήταν τόσο σοβαρές ώστε 93 περιπτώσεις παραπέμφθηκαν στον εισαγγελέα, ενώ σε 90 καταλογίστηκαν και πρόστιμα συνολικού ύψους 2,1 εκατ. ευρώ [...]

Πέμπτη, Νοεμβρίου 02, 2006

Συχνά οι οικονομολόγοι μιλάνε για άριστο επίπεδο μόλυνσης. Το γνωστό μότο, όμως, που υπάρχει σε τέτοιες περιπτώσεις είναι ότι το άριστο επίπεδο μόλυνσης πρέπει να είναι μηδενική μόλυνση. Το κατά πόσο αυτό είναι εφικτό, μάλλον, τελικά εξαρτάται από αυτόν που το υποστηρίζει. Η "Ελευθεροτυπία" της Τετάρτης αφιέρωσε αρκετό ρεπορτάζ για το θέμα των αδειών εκπομπών αερίων, καθώς για την παρούσα κατάσταση του θέματος. Παραθέτω μέρος των άρθρων και link στον τίτλο.

Η αντίθετη άποψη: "Φράγκο δεν πληρώνουν οι ρυπογόνες εταιρείες, συνεπικουρούμενες από τις εθνικές κυβερνήσεις κοροϊδεύοντας έτσι διπλά, τονίζει το γραφείο της Greenpeace. Ο Δημήτρης Ιμπραήμ εξηγεί τους λόγους: «Εχουν μετατρέψει οι μεγάλες βιομηχανικές χώρες το θέμα της ρύπανσης σε ένα καθαρά οικονομικό μέγεθος, το οποίο αγοράζεται ή πωλείται όπως οποιοδήποτε άλλο αγαθό στην αγορά»".

Ελλάδα εκτός ορίων

Οι ΗΠΑ πνίγουν τον πλανήτη : "Ο ΑΜΕΡΙΚΑΝΟΣ εκπέμπει κατά μέσο όρο περίπου 5 τόνους διοξειδίου του άνθρακα κάθε χρόνο"

3 άξονες σωτηρίας και άμεσα μέτρα¨: "Συνεχίζουμε να έχουμε αυξήσεις στις εκπομπές από τις μεταφορές. Δεν μειώνουμε τις εκπομπές από τους χώρους διάθεσης απορριμμάτων, τόσο τους ανεξέλεγκτους αλλά και τους ΧΥΤΑ». Αυτά τονίζει ο καθηγητής Δημήτρης Λάλας, διευθύνων σύμβουλος FACETS ΕΠΕ, με αφορμή την έκθεση της Επιτροπής Stern, η οποία όπως τονίζει, «επιβεβαιώνει την ύπαρξη κλιματικής αλλαγής που άλλωστε την καταγράφουν ακόμη και οι αρμόδιες αμερικανικές υπηρεσίες".

Τι προβλέπει το ...χρηματιστήριο των ρύπων : "Το 2003 συμφωνήθηκε η οδηγία 2003/87 για την Εμπορία Δικαιωμάτων Εκπομπών με συναπόφαση του Συμβουλίου και του Ευρωκοινοβουλίου, η οποία και ενσωματώθηκε στο Ελληνικό Δίκαιο".

Επτά χώρες-μέλη της ΕΕ δεν θα πετύχουν τους στόχους του Κιότο

Επτά χώρες-μέλη της ΕΕ -Αυστρία, Βέλγιο, Δανία, Ιταλία, Πορτογαλία, Ισπανία- θα υπερβούν τα όρια που θέτει το Πρωτόκολλο του Κιότο για τις εκπομπές αερίων του θερμοκηπίου, ανακοίνωσε την Παρασκευή η Ευρωπαϊκή Επιτροπή.

Οι προβολές στην τελευταία έκθεση της Ευρωπαϊκής Περιβαλλοντικής Υπηρεσίας, που δημοσιεύεται από την Επιτροπή, δείχνουν ότι οι «15» της ΕΕ θα μπορέσουν να πετύχουν τον κοινό στόχο μόνο αν εφαρμόσουν στο ακέραιο τα σχέδια για μείωση των εκπομπών.

«Οι προβολές αυτές δείχνουν ότι δεν υπάρχει περιθώριο για εφησυχασμό ή λάθη» δήλωσε ο επίτροπος Περιβάλλοντος Σταύρος Δήμας.

Σύμφωνα με το Πρωτόκολλο του Κιότο, οι «15» της ΕΕ πρέπει έως το 2012 να έχουν μειώσει τις συνολικές εκπομπές τους κατά 8%, σε σχέση με τα επίπεδα του 1990.

Όπως αναφέρει από τις Βρυξέλλες το Γαλλικό Πρακτορείο Ειδήσεων, με τις υπάρχουσες πολιτικές και μέτρα, οι «15» θα μειώσουν τις εκπομπές κατά μόλις 0,6%. Απαιτούνται επομένως δέσμες νέων μέτρων, συμπεριλαμβανομένης της αγοραπωλησίας πιστώσεων εκπομπής, μέσω της αγοράς ρύπων που δημιουργήθηκε με βάση το Κιότο.

«Όσοι δεν βρίσκονται στη σωστή πορεία πρέπει επειγόντως να εντείνουν τις προσπάθειες ώστε να πετύχουν τους στόχους, λαμβάνοντας αν είναι απαραίτητο περαιτέρω μέτρα σε εθνικό επίπεδο» δήλωσε ο Σταύρος Δήμας.

Έκθεση στη Βρετανία

Αν η διεθνής κοινότητα δεν λάβει θαρραλέα μέτρα κατά του φαινομένου του θερμοκηπίου, οι συνέπειες της κλιματικής αλλαγής στην οικονομία θα είναι συγκρίσιμες με τις επιπτώσεις ενός παγκοσμίου πολέμου, προειδοποιεί έκθεση για λογαριασμό της βρετανικής κυβέρνησης.

Η έκθεση του Νίκολας Στερν, πρώην οικονομολόγου της Παγκόσμιας Τράπεζας, εκτιμά ότι η αντιμετώπιση της κλιματικής αλλαγής θα απαιτήσει το 1% του παγκόσμιου ακαθάριστου προϊόντος. Αν όμως δεν ληφθούν μέτρα, οι επιπτώσεις θα κοστίσουν από 5 έως 20 φορές περισσότερο και το τίμημα θα μπορούσε έτσι να φτάσει τα 5,48 τρισ. ευρώ.

James Lovelock is among the planet's most interesting and productive scientists.

In fact, his so-called Gaia hypothesis was at first less clear than that— "hardly anyone, and that included me for the first ten years after the concept was born, seems to know what Gaia is," he has written. But the hypothesis has turned into a theory, still not fully accepted by other scientists but not scorned either. It holds that the earth is "a self-regulating system made up from the totality of organisms, the surface rocks, the ocean and the atmosphere tightly coupled as an evolving system" and striving to "regulate surface conditions so as always to be as favourable as possible for contemporary life."
Putting aside questions of planetary consciousness and will (beloved as they were by an early wave of New Age Gaia acolytes), the theory may help us understand how the earth has managed to remain hospitable for life over billions of years even as the sun, because of its own stellar evolution, has become significantly hotter. Through a series of processes involving, among others, ice ages, ocean algae, and weathering rock, the earth has managed to keep the amount of heat-trapping carbon dioxide in the atmosphere, and hence the temperature, at a relatively stable level.

PASADENA, Calif.--(BUSINESS WIRE)-EI Solutions, the systems integration arm of Energy Innovations, Inc., today announced that it will begin constructing a solar electricity system for Google's Mountain View, California, headquarters campus. With a total capacity of 1.6 megawatts - enough to supply 1,000 average California homes - the Google system will be the largest solar installation on any corporate campus in the United States and one of the largest on any corporate site in the world. The project will involve 9,212 solar panels provided by Sharp Electronics. A majority will be placed on the rooftops of some of the buildings in the Googleplex and others will provide shaded parking as part of newly constructed solar panel support structures on existing Google parking lots. The solar energy will be used to power several of Google's Mountain View office facilities.

"We are pleased to be working with EI Solutions to undertake this major initiative to bring green energy to the Google campus," said David Radcliffe, vice president of real estate at Google. "When the project is completed this spring, Google employees, shareholders and the community around us will begin to enjoy the environmental as well as economic benefits of clean, renewable energy generated on-site."

"It is a distinct pleasure to be involved with a company such as Google, which is committed to investing in alternatives to traditional fuel sources," said Andrew Beebe, president of EI Solutions. "Their understanding that solar electricity can provide tangible environmental benefits in an economically sound manner should be a model for other companies in California and throughout the US."

"We are particularly delighted with the extensive use of Sharp's cutting-edge technologies in this project as they're a natural match for companies looking to effectively generate green energy," noted Ron Kenedi, vice president, Solar Energy Solutions Group, Sharp Electronics.

The Oil Drum | The End of Fossil Energy

The Oil Drum | The End of Fossil Energy

A couple of months ago, I received an e-mail from John Howe, author of the book The End of Fossil Energy and the Last Chance for Survival. He indicated his concern that the public is not getting the message on Peak Oil, and he asked if I would be interested in receiving a copy of his book and helping him post some of his ideas to TOD. I accepted his gracious offer, and I received his book in the mail a few days later. A couple of weeks later, I read the book on a flight to San Francisco.

There's more… (2522 words) | Comments (233) | Permalink

There is something in the book for just about everyone, but I would especially recommend it as an introduction to the topic of Peak Oil. I told John I would post an essay here in order to help get his ideas out there. He has a 20-page White Paper that you can download here. I will post some excerpts from his White Paper below, but first I wanted to make a few observations.

There were a couple of things that really impressed me about John. First, he has laid out a plan for transitioning to a sustainable energy future. He calls this plan "The Five Percent Plan to Energy Sustainability", and he covers the details in Chapter 5. By actually committing a plan to writing, John is probably ahead of the vast majority of us in this debate. Most of us have various ideas for what we need to do to achieve sustainability, but I am sure that few of us have put as much thought into it as John has.

The other thing that really impressed me is that John practices what he preaches. He has built three completely solar-powered vehicles, including a 1962 MG Midget and a tractor he uses on his farm. He goes over some of the technical details in one of the appendices of the book. The experience John is gaining with his solar-powered vehicles can be a valuable asset to the world if we will learn from him. If the world had more John Howes out there, I wouldn't be nearly as concerned about the challenges facing us.



Delusions That Will Not Save Us

(But waste valuable time and dollars while we chase them down)

With the onset of peak oil and higher energy prices, there is a flurry of new and, in many cases, revived old panaceas. Some have a touch of legitimacy. Some are pure snake oil, some are only a way to profit either from selling books or from ill-directed research grants and tax incentives. Not necessarily in order:

  • Hydrogen-Hype: Now quieting down. Most people understand it has to come from fossil fuels, or if from renewables, is a terribly inefficient way to use precious non-fossil-sourced electricity. In addition, it is very dangerous and technically difficult to handle and store in compressed or cryogenic form.
  • Biofuels (exclusive of wood): Sunlight is very dilute and sporadic. Expecting the annual solar energy to replace the millions of years of concentrated solar energy in fossil fuels is impossible. As the fossil fuel base (nitrogen fertilizer, diesel fuel, irrigation- energy, etc.) for our food supply winds down, we will need ALL the biomass energy we can find just to feed ourselves. Also, biofuel production (esp. ethanol from corn) requires about as much fossil energy input as the resultant energy yield. The energy returned on energy invested (EROEI) is too close to unity to be worthwhile. Finally the intensive monoculture of crop land is not sustainable.
  • Wood: Somewhere between dilute annual sunlight-energy and concentrated fossil fuels is wonderful wood. But, it takes 50 to 100 years to grow a reasonable tree. Harvest at a quicker rate only depletes the forest, soils, and ecological balance. This signals the end of a civilization and is happening the world over and exacerbated; by increasing population and fossil-fuel powered harvesting equipment.
  • There's Plenty Left: We are now using about 6 barrels of oil (at one billion barrels, worldwide, every 12 days) for every single new barrel discovered. Natural gas is not far behind and can't be shipped overseas except as liquid natural gas (LNG). Coal and tar sands are more plentiful but contribute heavily to eco devastation and will soon approach an EROEI of unity, especially as oil runs down and the harder-to-reach, dirtier sources are mined.
  • Efficiency Will Save Us: Only if we concurrently reduce consumption (reverse growth and population). In most cases improved efficiency increases consumption due to increased value and numbers of consumers. ("Jevon's Paradox") In the long run, we must survive with no fossil energy at all.
  • Other Sources: Nuclear, hydro, geothermal, solar, and wind are all legitimate. But, except for solar and wind, all are limited by site availability or in the case of nuclear, finite fuel and waste problems. Total energy will be much less without fossil-fuels.
  • "Pie in the Sky": Abiotic oil, nuclear fusion, methyl hydrates, shale oil, perpetual motion machines, etc. None are proved.

Non-fossil Energy Sources

The Three fossil fuels (oil, coal, and natural gas) represent a non-renewable "bank account" being drawn down at an annual rate leading to complete depletion or the point of negative energy return on investment (EROEI) in less than one lifetime. This prediction can be challenged but more optimism will, in no way, change the obvious threat of the "Triple-Crisis." New unexpected discoveries might provide extra time and a better chance to effect a transition protocol to less population and a much lower-energy future. However, the desperate consumption of additional fossil fuels will only exacerbate the global warming component. A sustainable future can only come from sustainable, clean energy.

Nuclear

The best bet for continued, clean electricity on a large scale. But, sources of finite, fissionable uranium must be found and ultimately mined without cheap fossil energy. This scenario also assumes that acceptable waste disposal and protection from terrorism can be assured. Also, nuclear, like all other non-fossil energy sources except biofuels, produces only direct electricity. No matter what energy sources we use we will need a complete rethinking of our transportation system.

Hydro

Limited to acceptable sites nearly all of which have been used. Global warming has reduced water flow and electrical output in the last decade. Considerable fossil energy is required to replace dams, which ultimately fill with silt. Reversible pumped hydro at 85% efficiency (as well as nuclear) can be used to smooth the sporadic output of solar and wind.

Biofuels

Only for absolutely essential needs as liquid fuels, lubricants, etc. and with full understanding of the required energy input and the deleterious effect on crop land and food supply. See pages 7 and 12 for more details. Waste products will decline as a source of fuel because the original energy sources are finite and depleting.

Geothermal, Tidal, Wave, etc.

All are site specific and cannot be scaled up to be of importance.

Wind

A true, clean source that can be scaled up extensively especially while fossil fuels are still available for manufacture and installation. Sporadic electrical output could be smoothed by working in concert with solar PV and other available sources.

Solar PV (photovoltaic)

The best modern technology providing direct electricity on a local or centralized basis. Very dilute and sporadic but infinitely scalable and especially applicable to residential use as well as direct solar-powered tractors and cars. In all cases, the weak output needs to be coupled with battery storage and/or other sources. This is our best bet for a long, clean future including agricultural power and transportation. Small urban and suburban farms could use approximately 100 volt tractors with integral solar-panel arrays and large battery-packs. Huge commercial farms might better use a large portable separate array of 4 to 8 kilowatts peak power (300 to 600 square feet). With a 200 ft. #8 cable, this concept would allow working up to 3 acres almost on a one to one energy basis as long as there is direct sunlight. The portable central array could be moved to a new location or brought to the farm buildings in off-season. The high cost and availability of PV will require a 50 year scale-up from present minuscule levels. We need massive investment in solar PV and lead/acid battery recycling facilities.

Dear Colleague,

I invite you to help build what is fast becoming a seminal reference on understanding and managing the environment. With the recent public release of the Encyclopedia of Earth (http://www.eoearth.org/), scientists from around the world are joining to create a comprehensive, authoritative source of information about the environments of Earth and their interactions with society. The Encyclopedia is written and governed by experts working in a unique collaborative environment, and it has been released through the initial work of about 300 Authors and 100 Topic Editors. The Encyclopedia's oversight comes from an outstanding group of international scholars, our International Advisory Board (see below).

You can write on or edit any topic that interests you and that falls within the scope of Encyclopedia. Entries are from 250 to 5,000 words, geared to a general audience. Your articles can be drawn directly from existing material you have written, subject to any copyright restrictions. The Encyclopedia is built, maintained, and governed by experts like you via a specially adapted "wiki," an online resource that allows users to add and edit content collectively. Significantly, unlike other wikis, access to the Encyclopedia wiki is restricted to approved experts, and all content is peer reviewed and approved prior to being published at the free public site.

Contributing is easy: visit http://www.eoearth.org/, click on CONTRIBUTE TO THE EOE, and follow the guidelines there. The site also contains additional information about the project.

I encourage you to circulate this invitation widely among your colleagues.

Press Releases September 2006 - Flying Around the Globe on a Time Machine - United Nations Environment Programme

Press Releases September 2006 - Flying Around the Globe on a Time Machine - United Nations Environment Programme: " Flying Around the Globe on a Time Machine

Flying Around the Globe on a Time Machine United Nations Environment Programme Partners with Google Earth

Nairobi, 12 September 2006 – 'Flying' around a virtual planet earth, zooming in on environmental hotspots and comparing today's crisis zones with yesterday's areas of natural beauty: All this has become a reality today thanks to a partnership between the United Nations Environment Programme (UNEP) and Google Earth.

Images of retreating glaciers and melting ice in polar and mountain areas, explosive growth of cities such as Las Vegas, forest loss in the Amazon, rapid oil and gas development in Wyoming and Canada, forest fires across sub-Saharan Africa and the decline of the Aral Sea in Central Asia and Lake Chad in Africa: this and much more is being presented in a series of 'before and after' satellite images of our changing environment to over 100 million Google Earth users worldwide.

Beginning today, Google Earth – Google’s 3D virtual world browser – will feature UNEP: Atlas of our Changing Environment, offering satellite images of 100 environmental hotspots from around the world. The project builds on the success of UNEP’s very popular hardcover release One Planet, Many People: Atlas of our Changing Environment.

UNEP's Executive Director Achim Steiner said:” These satellite pictures are a wake-up call to all of us to look at the sometimes devastating changes we are wreaking on our planet. Through spectacular imagery, Google Earth and UNEP offer a new way of visualizing the dangers facing our planet today. By tapping into the global Google community, we are able to reach out to millions of people who can mobilize and make a difference."

The printed Atlas One Planet, Many People: Atlas of our Changing Environment was produced in cooperation with the National Aeronautics and Space Administration (NASA), the United States Geological Survey (USGS) and the University of Maryland, and launched on World Environment Day in June 2005.

UNEP: Atlas of our Changing Environment uses images from the 2005 publication together with satellite depictions of changes to African Lakes (based on the 2006 hardcover Africa’s Lakes: Atlas of our Changing Environment), along with several new images and updates, and brings them into the virtual world of Google Earth. Each location features multiple satellite images which are overlaid directly on Google Earth.

Most of the locations feature imagery from almost thirty-five years of global coverage produced by the Landsat programme. Using this invaluable record of our planet’s recent past, UNEP: Atlas of our Changing Environment documents hotspots of environmental change around the world.

The project coordinator, Ashbindu Singh, of UNEP's Division of Early Warning and Assessment said: "Google Earth technology already allows a more informative and accessible means of delivering information about our changing environment. By keeping pace with the changing world of technology and media, UNEP helps the environmental community keep pace with the real changes in our real world."

Google Earth enables users to put each image into a rich geographical context. At Lake Kivu, Uganda, an active volcano threatens to release a lethal cloud of carbon dioxide from the lake. The user can zoom into the city of Goma, caught between the volcano and the lake, and view the high resolution images showing its houses, roads and parks.

Lake Chad, a great shallow lake in West Africa which was once the sixth largest in the world, shrunk to a wetland one tenth its original size between 1963 and 2001. The user can follow the rivers that feed it to their sources, which no longer provide enough water to maintain the lake. Google Earth shows the countries and cities affected by the lake’s decline and offers the ability to search the internet for additional information about Lake Chad.

In the Trang Estuary along Thailand’s western shoreline, an explosion in shrimp farming can be seen cutting into the disappearing mangrove forests between January 1990 and October 2001. Jumping 500 km to the south, the user can see more mangrove forest being lost to agricultural conversion and urban expansion, as the population surrounding Kuala Lumpur, Malaysia, spreads from 40 km inland in January 1974, west to the coastal mangrove forests in January 2005.

'Flying' 2,500 km north across Southeast Asia, China’s economic powerhouse, Shenzhen, can be seen growing from a small city in the coastal forest in October 1979 to a sprawling industrial city with a population approaching 5 million in the greater metropolitan area by September 2004. Spinning the globe around to North America, enormous open pit mines in the Athabasca region of Alberta, Canada, can be seen where vast low-quality reserves of oil are being extracted from 'oil sands'.

Some of the new images featured on UNEP: Atlas of our Changing Environment on Google Earth:

Kantang, Thailand

Two satellite images from 31 January 1990 and 22 October 2001 show mangrove forests in the Trang River estuary in Thailand that are being rapidly converted for aquaculture.

The mangroves are under threat from upstream discharge of wastewater, industrial facilities and unsustainable aquaculture practices – particularly commercial shrimp farming. From 1975 to 1993, it is estimated that about half of Thailand's mangroves along its 2,560 km coastline were lost. The larger area of the Had Chao Mai Marine National Park, the Ta Libong Island Non-Hunting Area and the Trang River Estuaries has been designated a Ramsar Wetland Site and supports over 200 bird species including many 'critically endangered', 'endangered', 'vulnerable' and 'threatened' species.

Mangrove ecosystems are the interface between the marine and terrestrial ecosystems and provide important services to both. The fallen leaves and branches contribute important nutrients, making healthy nursery areas for the breeding of many marine species and in turn creating healthy fisheries. They are also prime habitat for migratory birds, amphibians and terrestrial species.

The international market for shrimp will likely continue to drive the development of commercial shrimp farming. Protection of areas such as Kantang will become increasingly important to preserving the dwindling areas of viable mangrove forest throughout the tropics.

Kuala Lumpur, Malaysia

With a population over 1.4 million (and approximately twice that number in the greater metropolitan area), Kuala Lumpur is the largest city in Malaysia and is growing rapidly. Its sprawl is now encroaching on the mangrove forests at the coastline (approximately 35 km to the west of the city centre).

Landsat satellite images from 1974 through 2005 show the gradual spread of development and the loss of mangrove forest that has resulted. By 1975, many areas of mangrove had already been converted to agriculture. As thirty years passed, the agricultural areas expanded and more mangroves were converted to farms. At the same time, the images show the agricultural areas being converted to industrial and urban land use. Elsewhere along the Malaysian coastline, mangroves are rapidly being converted to commercial shrimp farms. Forestry Department statistics show that peninsular Malaysia had 85,800 hectares (214,500 acres) of mangrove swamp forests in 2003, down from 86,497 hectares just one year earlier.

Mangrove forests are biologically diverse and highly productive ecosystems that offer valuable habitats to a wide variety of both marine and terrestrial species. They are being lost at an alarming rate throughout the tropics. Protection of these areas may be needed to ensure the survival of this valuable natural resource.

Shenzhen, China

The city of Shenzhen is located just across from Hong Kong and southeast of the Zhujian (Pearl) River Delta Region in China. The city has been the focus of intense urbanization, known as the Shenzhen Special Economic Zone (SSEZ). Comparison of satellite images shows the dramatic change in the landscape from 1979 to 2004, as thousands of high-rise buildings and factories have replaced earlier agricultural and vegetated areas.

It is estimated that over the next quarter-century, almost all population growth will occur in cities, most of it in less developed countries. By 2030, more than 60 per cent of the world’s population will live in urban areas. Already, one of every three urban dwellers lives in a slum. And in too many of the world’s expanding towns and cities, environmental safeguards are few and planning is haphazard.

The environmental consequences of urban growth are considerable. Cities are prolific users of natural resources and generators of waste. They produce most of the greenhouse gases that are causing global climate change. They often degrade local water quality, deplete aquifers, pollute the marine environment, foul the air and consume the land, thereby devastating biological diversity.

Athabasca Oil Sands, Alberta, Canada

Vast reserves of low quality oil underlie the boreal forest surrounding Fort McMurray in northern Alberta, Canada, in the form of 'Athabasca oil sands'. While these reserves have been known since the early 20th century, the high cost of extracting usable oil from these 'oil sands' has limited the development of a viable oil sands mining industry. In 2003 the rising cost of crude oil led to Canada reevaluating the oil sands as a viable resource.

Canada's National Energy Board predicts $125 billion in investments for creation and expansion of oil sands mining in the Athabasca area between 2006 and 2015 which will take production to around 3 million barrels per day. Local people including the Native American population are concerned that exploitation will come at too great a cost to the environment. The government of Alberta plans to propose a surface mining area of 280,000 hectares, an area approximately four times the size of the City of Calgary.

In 1967 The Great Canadian Oil Sands Company began construction at its Mildred Lake site. In 1974 they were joined by the Syncrude Corporation which began construction of a mine in the same area. By early 2006 the mining operations had expanded to cover an area roughly 30 km by 20 km. Syncrude operates a second mine, the Aurora, approximately 30 km to the north of Mildred Lake.

Manaus, Brazil

Manaus, the capital of the state of Amazonia, is located on the north bank of the River Negro at its confluence with the Solimoes River, which extends eastward as the Amazon River. The population of Manaus grew by more that 65 per cent between 1993 and 2003 to its current population of over 1.5 million.

Two Landsat images document the conversion of forest areas due to logging and urbanization between 1987 and 2001. In addition to the urban expansion evident in the area surrounding the city, increased logging and road construction can be observed in the 2001 image.

About 15 km from Manaus, Rio Negro (Black River) meets Rio Solimoes to create an amazing confluence of the brownish white water from the Saliomes joining the black water (caused by the very high acidity from tannin) from the Rio Negro.

Print Story: UN, Google team up to highlight global environment crises on Yahoo! News

Rampant forest destruction, retreating glaciers and explosive urban growth became a visual reality for millions with the launch of a new partnership between the United Nations and internet search giant Google.

Under the scheme announced by the Nairobi-based UN Environment Programme, bird's eye before-and-after views of 100 UNEP-identified global environmental hotspots were posted to Google's popular Google Earth browser.

"These satellite pictures are a wake-up call to all of us to look at the sometimes devastating changes we are wreaking on our planet," UNEP chief Achim Steiner said in a statement Wednesday.

He described the selection photographs as "spectacular imagery" that offered a compelling "new way of visualizing the dangers facing our planet today" and would lead to greater awareness and concern about ecological damage.

"By tapping into the global Google community, we are able to reach out to millions of people who can mobilize and make a difference," Steiner said.

Google Earth, which offers satellite views of the planet, has about 100 million users worldwide who will now be able to access UNEP's "Atlas of Our Changing Environment" under the program, the agency said.

Among the 100 "hotspots" included are the dwindling Amazon rainforest, melting polar ice caps, the startling declines of Central Asia's Aral Sea in Russia and Africa's Lake Chad and rapid urbanization of the US city of Las Vegas and southern Chinese metropolis of Shenzen, it said.

Other crisis points highlighted include the rampant destruction of mangrove forests in Southeast Asia, notably in Thailand and Malaysia, and the effects of open-pit oil exploration in the Athabasca region of Canada's Alberta province, it said."

In Gamble, Calif. Tries to Curb Greenhouse Gases - New York Times

In Gamble, Calif. Tries to Curb Greenhouse Gases - New York Times: "In Gamble, Calif. Tries to Curb Greenhouse Gases
By FELICITY BARRINGER

SACRAMENTO — In the Rocky Mountain States and the fast-growing desert Southwest, more than 20 power plants, designed to burn coal that is plentiful and cheap, are on the drawing boards. Much of the power, their owners expected, would be destined for the people of California.

But such plants would also be among the country’s most potent producers of carbon dioxide, the king of gases linked to global warming. So California has just delivered a new message to these energy suppliers: If you cannot produce power with the lowest possible emissions of these greenhouse gases, we are not interested.

“When your biggest customer says, ‘I ain’t buying,’ you rethink,” said Hal Harvey, the environment program director at the William and Flora Hewlett Foundation, in Menlo Park, Calif. “When you have 38 million customers you don’t have access to, you rethink. Selling to Phoenix is nice. Las Vegas is nice. But they aren’t California.”

California’s decision to impose stringent demands on suppliers even outside its borders, broadened by the Legislature on Aug. 31 and awaiting the governor’s signature, is but one example of the state’s wide-ranging effort to remake its energy future.

The Democratic-controlled legislature and the Republican governor also agreed at that time on legislation to reduce industrial carbon dioxide emissions by 25 percent by 2020, a measure that affects not only power plants but also other large producers of carbon dioxide, including oil refineries and cement plants.

The state’s aim is to reduce emissions of climate-changing gases produced by burning coal, oil and gas. Other states, particularly New York, are moving in some of the same directions, but no state is moving as aggressively on as many fronts. No state has been at it longer. No state is putting more at risk.

Whether all this is visionary or deluded depends on one’s perspective. This is the state that in the early 1970’s jump-started the worldwide adoption of catalytic converters, the devices that neutralize most smog-forming chemicals emitted by tailpipes. This is the state whose per capita energy consumption has been almost flat for 30 years, even as per capita consumption has risen 50 percent nationally.

Taking on global warming is a tougher challenge. Though California was second in the nation only to Texas in emissions of carbon dioxide in 2001, and 12th in the world, it produced just 2.5 percent of the world’s total. At best, business leaders asked in a legislative hearing, what difference could California’s cuts make? And at what cost?

California, in fact, is making a huge bet: that it can reduce emissions without wrecking its economy, and therefore inspire other states — and countries — to follow its example on slowing climate change.

Initiatives addressing climate change are everywhere in California, pushed by legislators, by regulators, by cities, by foundations, by businesses and by investors.

Four years ago, California became the first state to seek to regulate emissions of carbon dioxide from automobile tailpipes. Car dealers and carmakers are challenging the law in federal court.

In late August, Gov. Arnold Schwarzenegger signed a measure requiring builders to offer home buyers roofs with tiles that convert sunlight into electricity. Homeowners in some communities are already choosing them to reduce their electric bills.

California, which has for decades required that refrigerators, air conditioners, water heaters and other appliances become more energy efficient, just added to the list: first, chargers for cellphones or computers; second, set-top boxes and other remote-controlled devices. Those categories consume up to 10 percent of a home’s power.

Last fall, California regulators barred major investor-owned electrical utilities from signing long-term contracts to buy energy unless the seller’s greenhouse-gas emissions meet a stringent standard.

“We are dealing with it across the board,” said Michael R. Peevey, the president of the Public Utilities Commission. By contrast, the Bush administration has been averse to any legislative assault on climate change.

Opponents say California may hurt its own residents with its clean-energy mandate. Scott Segal, a lawyer for Bracewell & Giuliani who represents electric utilities, summarized California’s policy as: “All electrons are not created equal. We’re going to discriminate against some of them, and create artificial barriers in the marketplace for electricity.” California consumers could end up paying more for their energy and struggling to find enough, Mr. Segal said.

Is California dreaming? Can its multifaceted approach become a toolkit for other states? Will investors make the state the incubator for clean-energy technologies that will reduce its energy bills and buoy its economy? Or will all this turn California into a stagnating economic island of ever-rising electricity prices and ever-rolling blackouts?

One thing is certain: The issue will not go away. This summer, a brutal California heat wave killed roughly 140 people. A 2004 National Academy of Sciences report predicted that, at the current growth rate of emissions, there would be at least five times as many heat waves in Los Angeles by 2100 compared with the current historical average, and twice as many heat-related deaths.

The study predicted that at least half the state’s alpine forests would disappear by century’s end, and that the Sierra snowpack — crucial to California’s water supply — would decline by at least 29 percent and as much as 70 percent.

There seems to be political support, in California and nationally, for action on climate change. Statewide, a July 26 poll from the Public Policy Institute of California showed that 79 percent of 2,051 people surveyed said that global warming was a “very serious” or a “somewhat serious” threat to the state’s economy and quality of life. The findings mirrored those of a national poll of 1,206 people conducted in mid-August by The New York Times and CBS News.

But polling organizations have asked little about the potentially painful sacrifices that may be required.

The Car Culture

Back in the 1950’s, when the movie director George Lucas was growing up, cars rocked around the clock in Modesto, and they were so enshrined in his 1973 hit, “American Graffiti.” The movie reaffirmed what much of the nation knew — there was no car culture like California’s. Sleek convertibles? Muscle cars? Sport utility vehicles? Many were hatched in the design studios of Detroit, but popularized by Hollywood movies and celebrities, and by plain old California consumers.

Fast forward to August. In the middle of the sales lot at Modesto Toyota sat a long row of sport utility vehicles the dealership had acquired as trade-ins in previous weeks. Leaning on a 2006 Ford Expedition, George S. Ismail, a sales manager, said, “We’re getting a lot of people trading in their sport utility vehicles for smaller cars.” Even heavily discounted, the used S.U.V.’s sit for weeks.

Yet Modesto Toyota is breaking records, Mr. Ismail said, selling about 400 vehicles a month, up from 260 a year ago. Most are small cars — Camrys and Corollas. Some are hybrid vehicles that use even less fuel, like the Prius. One-quarter of 200,000 new hybrid vehicles registered nationwide in 2005 belonged to Californians, according to the automotive analyst R. L. Polk.

With smaller cars increasingly popular, California now burns less gasoline per capita than all but six states. Burning less gasoline cuts carbon dioxide. Tailpipes account for more than half the state’s carbon dioxide emissions, federal figures show.

Much of this change in driver taste is attributable to the higher price of gasoline. But what if gasoline prices fall again and bigger, less efficient vehicles become more popular? California has an answer.

It came from Assemblywoman Fran Pavley, a Democrat and former schoolteacher who drives a Prius and whose South Coast district has a bird’s-eye view of the smoggy Los Angeles basin. Four years ago Ms. Pavley wrote the first state law regulating carbon dioxide emissions from cars and trucks. It requires vehicle makers to eventually reduce the average emissions of carbon dioxide of the mix of cars it sells in California by 30 percent, beginning with the 2009 model year. Light trucks, including sport utility vehicles, must meet the same standard by the 2016 model year.

Ten states, including New York, New Jersey and Connecticut, have followed suit. Canada instituted voluntary emissions reductions at similar levels, which major automobile manufacturers have agreed they can meet. “We think that, coupled with Canada, we’re now over one-third of the market,” Ms. Pavley said in an interview.

But automobile manufacturers and some dealerships have vowed to wipe her law from the books. Their lawsuit’s central assertion is that, by regulating carbon dioxide emissions, California is using a backdoor means to control fuel efficiency, which, under the federal Energy Policy and Conservation Act, is the exclusive preserve of the federal Transportation Department. To produce less carbon dioxide, cars would have to be more fuel efficient.

On Sept. 15, Judge Anthony W. Ishii of Federal District Court in Fresno will hear arguments on California’s request to dismiss the case. If the lawsuit survives, the first hearing is set for January. This schedule overlaps with that of another case with direct bearing on this issue. The Supreme Court, petitioned by a dozen states, led by Massachusetts, and three cities, including New York, will decide whether the law requires the Environmental Protection Agency to declare carbon dioxide a pollutant and to regulate it. The Bush administration contends it has no authority to do either.

If the Supreme Court accepts the administration’s arguments, it will not help California in its legal fight against Detroit, because a key to the state’s case is the contention that carbon dioxide is in fact a pollutant under the Clean Air Act.

Hungry Electronics

Imagine all the small electronic devices in a modern home — iPods and handheld organizers, cellphones and laptops — charging at a power strip.

Arthur H. Rosenfeld, a member of the California Energy Commission, knows how much electricity is wasted when people unplug the devices but leave the charger plugged in. Dr. Rosenfeld estimates that such chargers — along with appliances like televisions that draw power even when they are off because they are designed to respond to remote controls — use up to 10 percent of an average home’s power.

He calls them “vampires” — things with teeth that suck power at night.

Recently, Dr. Rosenfeld proudly held up a small green cellular phone charger that consumes less than half a watt of electricity — a fifth as much as its predecessors — when left plugged into an outlet. It meets state standards that take effect in 2007. The same standards will require sharp power cutbacks from audio and video equipment, both when the devices are in use and when they are standing by for a remote signal.

Since the 1970’s, California’s energy-efficiency standards have reduced electricity consumption by the equivalent of the output of more than 20 average power plants, Dr. Rosenfeld said. And the standards have become templates for other states and Washington. Nationally, Dr. Rosenfeld added, energy-efficiency policies have saved the economy $700 billion since the 1970’s.

But why would utilities, which sell electricity, have any interest in seeing sales diminish? In 1982, the Public Utilities Commission decoupled utilities’ sales and their profits by allowing rate increases for utilities that helped customers cut energy use.

The logic was that for every dollar the consumer did not spend on energy, the utility would get real income — say 15 cents, which would exceed the profit the utility could have made on that dollar. For consumers, efficiency savings more than offset the rate increases. “Even though rates go up, bills go down,” said Mr. Harvey of the Hewlett Foundation.

Ralph Cavanagh, the co-director of the energy program at the Natural Resources Defense Counsel, said: “Every other state in the country rewards utilities for selling more energy. It’s a perfectly perverse incentive.”

Mr. Peevey, of the utilities commission, said he expected new efficiencies to absorb half the increase in demand as the state grows to 40 million people, from 38 million.

Mr. Peevey’s commission has also been a prime mover in increasing state support for residential solar power. Solar energy remains four times as expensive as electricity produced by conventional fuels. But, he said, “the idea is to make the solar industry a self-sustaining, economically viable industry,” and to make the cost come down.

California businesses and investors, public and private, are getting into the act. The state’s huge pension fund, Calpers, is committing just under $1 billion to renewable-energy investments. Among the early incentive-driven ventures in solar power are the homes in the Carsten Crossings subdivision in Rocklin, a Sacramento suburb. In August, Mr. Schwarzenegger signed legislation making solar panels a standard option for new-home buyers by 2012 and ensuring that utilities reduce homeowners’ bills based on the electricity returned to the grid.

Some of those incentives were available when construction started. Now four families have moved in. They see themselves as pragmatists, not crusaders. “This is the next logical step” in construction, said one of the homeowners, Lt. Col. Thomas Sebens, a specialist in drone aircraft at Beale Air Force Base.

Their roofs show how public and private decisions, markets and government, have meshed. T. J. Rodgers, a fiercely anti-regulatory entrepreneur, underwrote the solar cells’ production. The PowerLight Corporation, based near San Francisco, bought the cells from Mr. Rodgers’s company, the SunPower Corporation, and turned them into roof tiles. The tiles ended up on houses built by Grupe Homes, based in Stockton, because state utility regulators established a $5,500 state-financed rebate for builders who install similar systems, which cost $20,000. Federal law gives home buyers a $2,000 tax credit; state law guarantees lower electric bills as utilities buy back power homeowners do not need.

The July utility bills, the new homeowners’ first, were the talk of the neighborhood.

Larry Brittain, an office products salesman with a four-bedroom, 2,400-square-foot home, was the winner at $73.27 for electricity in the month ending July 25 — the hottest July on record. For the last 10 June days in a similar house nearby, his bill was $103.

“This is a bet with a winning hand,” Mr. Brittain said. “You can’t lose.”

Pressure on Suppliers

In Gerlach, Nev., 100 miles north of Reno, a high desert butte was made ready two years ago for its wedding to the Granite Fox Power Project, a plant designed to burn pulverized Western coal. Electrical transmission lines were close by.

But, like Miss Havisham in Dickens’s “Great Expectations,” Gerlach waits for a groom that may never arrive. The plant was a certain source of significant new carbon dioxide emissions. Mr. Cavanagh predicted that it “would wipe out all the carbon dioxide savings from California’s spectacularly successful efforts to save electricity during 2001 and 2002.”

Southern Californians would likely be the eventual customers. But last fall, the California Public Utilities Commission barred the investor-owned utilities it regulates from signing long-term contracts for electricity if the emissions exceeded those of the cleanest gas-driven plants. The only technology that could accomplish that with coal is expensive and has not been perfected.

Said Mr. Peevey of the commission, “All we’re saying is, Fine, you send it here, but it has to be, in terms of air quality and greenhouse gas emissions, it has to be comparable to the newest combined-cycle gas turbine.” One fifth of California’s electricity comes from coal, the vast majority of it from outside the state.

This past winter, Sempra Energy, the parent of San Diego Gas & Electric and Sempra Generation and the developer of Granite Fox, put the project up for sale. Neal E. Schmale, Sempra’s president, said the ruling had had a negligible impact on the decision. High natural gas prices prompted the company to invest in gas storage and terminals instead, Mr. Schmale said.

Among California environmentalists, however, the “for sale” sign on Granite Fox was taken as a victory for a pioneering policy that reaches beyond the state’s borders. V. John White, an environmental lobbyist in Sacramento, compares building a Southwestern power plant to building a mall: California is a desirable anchor tenant.

But California is also the state where electricity deregulation foundered in 2000; bills soared and an economic crisis ensued. Even without a crisis, Californians’ electricity rates are about 40 percent above the national average.

Robert McIlvaine, a coal industry consultant from Northfield, Ill., said, “If you are going to generate electricity from gas, the cost of doing so is going to be considerably greater than coal — 50 percent more or 100 percent more.”

But, Mr. Harvey said: “People don’t pay rates. They pay bills. You can have twice the rate and half the consumption and be just as happy.”

On Aug. 31, legislators enacted the bill sponsored by the State Senate president, Don Perata, Democrat of Oakland, and extended the commission’s rule to all power providers.

Business people ask if this could provoke another crisis. Power-plant siting experts, like Thomas A. Johns, the vice president of development at Sithe Global Power, a New York company, say that, in the short term, the loss of California business may not matter much to the merchants of power in the Southwest. Fast-growing cities like Phoenix and Las Vegas are ready markets.

In the long run, however, “California is a big piece” of the total consumption in the West — 40 percent, Mr. Johns said. “If 40 percent of the Western load will not buy coal, you will have less coal.”

The risk, both Mr. Johns and Mr. Schmale said, is in increasing the state’s reliance on natural gas, whose price has been extremely volatile in recent years. (California law bars construction of nuclear plants until the questions of waste disposal are resolved.)

“When you exclude coal and nuclear from your base load,” Mr. Johns said, “you’ve only got one option, and that’s natural gas.” Another measure awaiting the governor’s signature toughens standards by requiring that by 2010, 20 percent of the energy sold in California comes from a portfolio of renewable sources, like geothermal and wind. Last year, 10.7 percent of California’s power came from renewable sources.

New renewable energy sources could make prices less volatile, but Mr. Schmale of Sempra said California’s policy makers need to muster “the political will” to build transmission lines and “all those other things that would be necessary to make the environmental things work.”

Caps, Costs and Credits

Perhaps the most ambitious measure California has undertaken is the newly mandated 25 percent reduction in carbon dioxide emissions. “If we do it right,” Mr. Schwarzenegger said at a news conference, “it can be an example for the rest of the world and the rest of the country to see.” If not, the concept could be discredited.

The law, sponsored by Ms. Pavley and the Assembly speaker, Fabian N??ez, Democrat of Los Angeles, gives the California Air Resources Board authority to set industry-specific targets for emissions reductions, effective in 2012, and to establish mechanisms — including the creation of emissions allowances that companies might trade or bank — to facilitate compliance. These targets would be adjusted from 2012 to 2020 to meet the 25 percent goal.

Those who have studied the question agree that the new system will cost consumers more. “A cap-and-trade system will raise the cost of electricity to consumers to some degree,” said Lawrence H. Goulder, a professor of environmental and resource economics at Stanford University.

As the European Union found after the 1997 Kyoto Protocol, figuring out how to assign emissions credits is not easy.

Whatever the decisions, chances are that they will be met by a lawsuit. Margo Thorning, the chief economist at the American Council for Capital Formation, a group supporting business interests, argues in a study that “sharp cutbacks in California’s energy use would be necessary to close the 41 percent gap in 2020 between projected emissions” and the cuts the law requires. Dr. Thorning added in an interview, “The technologies that will enable us to move quickly in a cost-effective way away from fossil fuel just aren’t there yet.”

Allan Zaremberg, president of the state Chamber of Commerce, predicted that businesses would flee to unregulated areas and continue to emit climate-changing gases.

Dr. Thorning’s study was countered in mid-August with a study by David Roland-Holst, an adjunct professor of agricultural and resource economics at the University of California, Berkeley. Professor Roland-Holst argued that the new law would add $60 billion and 17,000 jobs — in fields like alternative energy — to the California economy by 2020 by attracting new investment.

James D. Marston, the head of state global warming programs for Environmental Defense, the New York group that helped lead the fight for California’s new carbon cap, said, “We’ll look back in 10 years and say this was the final breakthrough and the final political consensus that we have to do something meaningful on global warming.”

How To Survive Global Warming - David Shenk - Slate Magazine

How To Survive Global Warming
Saturday, Sept. 9, 2006
"Ιnconveniently, the earth is getting warmer. Polar ice caps are melting, oceans are rising, coasts are eroding, and weather patterns may be shifting. Scientists are predicting increased droughts, floods (not a contradiction), wildfires, a massive disruption of agriculture and the food chain, and more severe storms—especially hurricanes. The sea level might rise by several feet in this century alone. The best-case scenarios look pretty awful.

This is what we might call a slow-motion catastrophe—the proverbial frog in the slowly heated pot. It happens so insidiously, we never quite have that impulse to react. It also sounds innocuous on its face—average temperatures higher by a few measly degrees? So we turn our air conditioners up a notch in the summer and buy more property in northern Canada. What's the big deal?

The problem is that each tiny increase brings on a cascade of effects in weather, crops, migration, species interdependence, and so on. More rain here, less rain there. Hotter, drier earth means fewer microscopic worms fertilizing the soil, lower crop yields, and on and on and on. One quick glimpse at the minimum of devastation: The British government's chief scientist recently estimated that an increase of 5.4 degrees Fahrenheit (3 degrees Celsius) was the minimum we could hope for, even if we managed to stabilize carbon dioxide emissions in the near future, and that this temperature increase would result in a decrease of 200 million to 400 million tons of grain production throughout the world—and subsequently threaten starvation for 400 million people.

Other possible inconveniences coming our way include landslides, sewage overflows, insect plagues, forest-fire epidemics, and massive coastal erosion (according to a recent EPA study, my own in-laws' Delaware beach cottage stands a decent chance of being underwater before the end of the century). The American Great Plains will suffer diminished crop yields, while some Canadian regions become more productive. We'll lose a massive number of high alpine areas, salt marshes, and wetlands. Enormous human migrations could disrupt cities and nations. Smog and asthma could increase, fish stocks could decrease. Malaria and dengue fever could become prominent in the United States. Mosquitoes are going to love the 21st century.

The good news is, everyone reading this will be dead before nature's wrath is fully revealed. The bad news is, most of us have children, or hope to. A couple of generations down the line, Disney kids may ride on crazy underwater rides like Atlantis! and Boston! College girls will go wild on the spring break beaches of Pittsburgh and Albany. Don't even think about New Orleans being around. (Visit this clever adjustable map to see how ocean rises of 1-14 meters will affect your region in centuries to come.)

Even today, you may be more exposed than you think you are. I was surprised to learn that New York City once again pops up on the vulnerable list, not just for future sea rises but for right now. According to the U.S. Army Corps of Engineers, a Category 4 storm making landfall at just the right spot could put Kennedy airport under 20—no typo, 20—feet of water, bury New York's tunnels and subways, and flood out portions of residential Manhattan, Brooklyn, and Queens. Because of its high bridges and population mass, the city would need far more evacuation time than any other American city, but since Atlantic hurricanes tend to move much more quickly than Gulf hurricanes, such lead time simply might not be available.

What can one do? First: Vote. Global warming may or may not be a disaster we can avert, but we certainly have no chance if we continue to steer the wheel right into it. The United States ought to have signed on to the Kyoto Protocols years ago, and we ought to be leading the way in exploring alternative, renewable sources of energy.

Second: Act. There are already several painless ways for consumers to be dramatically more energy efficient and environmentally friendly: fuel efficient cars, Energy Star appliances, fluorescent bulbs, etc. One intriguing new experiment is TerraPass, a voluntary program that enables car owners to be "carbon neutral" by paying between $30 and $80 annually to remove roughly the same amount of carbon dioxide from the atmosphere that their car emits. Buy a TerraPass for each of your cars, and buy an extra for your stubborn father-in-law who still thinks recycling is a bad idea.

Third: Brace yourself. No matter what we do, increasingly severe hurricanes and beach erosion are on their way. Current coastal property owners should buy whatever insurance they can and look seriously at the long-term forecasts. Think Katrina. Would your beach cottage survive a Category 4 hurricane? Is there anything you can do to prepare for one? Prospective owners should think very carefully before they sink the family fortune into a plot of land that may eventually be home to living coral and sea algae. If you build a new house in a hurricane-prone region, consider new superstrong fortifications such as concrete walls and roofs, deep reinforced structural columns, frames bolted to the foundation, and impact-resistant windows.

On the flip side, consider investing in cooler climates and inland property. While it's impossible to predict precise outcomes from major climate change, it is fair to infer that elevation will be good, that the northern portion of North America will become more and more hospitable, and that tomorrow's new coastline will be every bit as desirable as today's,"

WorldChanging: Tools, Models and Ideas for Building a Bright Green Future: California Passes Law to Cap CO2 Emissions

WorldChanging: Tools, Models and Ideas for Building a Bright Green Future: California Passes Law to Cap CO2 Emissions: "California Passes Law to Cap CO2 Emissions | WorldChanging Team

Alana Herro writes for Eye on Earth (e²), a service of World Watch Magazine in partnership with the blue moon fund. e² provides a unique perspective on current events, newly released studies, and important global trends.

On August 31, the California legislature passed a bill establishing the most extensive carbon dioxide (CO2) emission controls yet in the United States. The law requires a 25 percent reduction in state CO2 emissions by 2020, with the first major controls taking effect in 2012. The California Air Resources Board, the agency that enforces the state’s air pollution controls, will be the main authority in establishing emission targets and noncompliance penalties for the law, which also allows for business incentives to reach the goals.

Several northeastern U.S. states signed a regional agreement to reduce CO2 emissions in December of 2005 but their target would reduce emissions by only some 24 million tons. The California mandate, which aims to cut emissions to their 1990 level, will result in cuts of some 174 million tons.

Opponents worry the new law will hurt California businesses and actually contribute to global warming by raising compliance costs to prohibitive levels. “If our manufacturers leave, whether for North Carolina or China, and they take their greenhouse gases with them, we might not have solved the problem but exacerbated it instead,” warns Allan Zaremberg of the California Chamber of Commerce.

Supporters hope that the legislation will instead inspire other states—and eventually the federal government—to follow suit. “The success of our system will be an example for other states and nations to follow as the fight against climate change continues,” noted California Governor Arnold Schwarzenegger on August 30. And some business leaders believe the law will actually benefit the state economy by creating industries and jobs. “The issue of climate change is important and needs to be dealt with,” explains Peter Darbee of Pacific Gas and Electric, echoing arguments at an April U.S. Senate hearing on mandatory federal carbon caps. “Since the bill has a market-based program, it will work efficiently and effectively for businesses.

U.S. Leads World in Climate Refugees

Hurricane Katrina, which made landfall in late August 2005, forced a million people from New Orleans and the small towns on the Mississippi and Louisiana coasts to move inland either in state or to neighboring states, such as Texas and Arkansas. Although nearly all planned to return, almost a year later 375,000 - or a full third of those million evacuees - have yet to return. Unlike in previous cases, when residents typically left areas threatened by hurricanes and returned when authorities declared it was safe to do so, many of these evacuees are finding new homes. In this respect, the U.S. hurricane season of 2005 was different. Record-high temperatures in the Gulf of Mexico surface waters helped make Hurricane Katrina the most financially destructive hurricane ever to make landfall anywhere [see whole article...]

Ενα δέντρο μεγαλώνει στις μεγαλουπόλεις όπως το Σάο Πάολο της Βραζιλίας. H ιδέα των οικολογικών πόλεων είναι η τελευταία ελπίδα του πλανήτη μας

Πριν από 100 χρόνια η μεγαλύτερη πόλη στoν κόσμο ήταν το Λονδίνο, με πληθυσμό 6,5 εκατομμύρια. Σήμερα το Τόκιο το υπερβαίνει σε μεγάλο βαθμό. Εχοντας μόλις το ένα τέταρτο του πληθυσμού του Λονδίνου πριν από έναν αιώνα, η ιαπωνική πρωτεύουσα έχει φθάσει σήμερα τα 34 εκατομμύρια κατοίκους, καταλαμβάνοντας την κορυφή του πίνακα με τις μεγαλύτερες πόλεις του πλανήτη. H εντυπωσιακή ανάπτυξη του Τόκιο οφείλεται, σε μεγάλο βαθμό, σε έναν και μοναδικό παράγοντα: τη μετακίνηση από την ύπαιθρο προς την πόλη. Δεν είναι η μοναδική πόλη που έχει ξεπεράσει σε πληθυσμό το Λονδίνο, το οποίο με 7,5 εκατομμύρια δεν περιλαμβάνεται καν στην πρώτη εικοσάδα. Αυτή τη στιγμή, σε δεκάδες πόλεις στον πλανήτη συντελείται μια μετακίνηση από τις αγροτικές προς τις αστικές περιοχές, οδηγώντας μας σε μια καθοριστική στιγμή της ανθρώπινης ιστορίας. Το 1900 οι περισσότεροι άνθρωποι ζούσαν στην ύπαιθρο και μόλις λίγο παραπάνω από το 10% του παγκόσμιου πληθυσμού ζούσε στις πόλεις. Από τον επόμενο χρόνο, όπως προβλέπει η Διεύθυνση Πληθυσμού του Οργανισμού Ηνωμένων Εθνών, για πρώτη φορά στην Ιστορία περισσότεροι άνθρωποι θα ζουν σε πόλεις από ό,τι στην ύπαιθρο και η μεγαλύτερη ανάπτυξη θα σημειωθεί στις «μεγαπόλεις», με πληθυσμό άνω των 10 εκατομμυρίων.

«Το ξέρατε ότι τα αμερικανικά κτίρια είναι υπεύθυνα για το 1/3 της καταναλούμενης ενέργειας ολόκληρης της χώρας;». Με αυτό το συγκλονιστικό στοιχείο καλωσορίζει τους επισκέπτες της η ιστοσελίδα μιας πρωτοποριακής έκθεσης που πραγματοποιείται ήδη από τον Μάιο και θα διαρκέσει μέχρι τον Ιούνιο του 2007, στο Εθνικό Μουσείο Αρχιτεκτονικής στην Ουάσιγκτον.

Τρόπος ζωής

Η έκθεση «Το πράσινο σπίτι: Νέες οδηγίες για βιώσιμη αρχιτεκτονική και εσωτερικό σχεδιασμό» βάζει τον «πράσινο» τρόπο ζωής στο επίκεντρο, προσφέροντας έμπνευση σε όσους τολμούν να ονειρεύονται το κάτι παραπάνω, αλλά και πληθώρα άλλων πιο απλών λύσεων για όλους εμάς που θέλουμε να κατανικήσουμε τις καταστροφικές για το περιβάλλον συνήθειές μας. Σκοπός της έκθεσης είναι να δείξει στους επισκέπτες πώς με έξυπνες επιλογές –ακόμη και απλές καθημερινές– μπορούμε να εξοικονομήσουμε ενέργεια, να γλιτώσουμε χρήματα και να υποστηρίξουμε πιο πράσινους και υγιεινούς τρόπους ζωής μέσα στα σπίτια μας. Με παρουσιάσεις και διαλέξεις, με επισκέψεις σε πρότζεκτ ανακαινίσεων ή κατασκευής σπιτιών τέτοιου τύπου, με οικογενειακά προγράμματα, αλλά και ένα κατατοπιστικό site (www.nbm.org/Exhibits/greenHouse2/greenHouse.htm), η έκθεση προσφέρει κάτι για όλους.

Γι’ αυτούς που ονειρεύονται το κάτι παραπάνω, υπάρχει το πλήρως περιβαλλοντικά φιλικό σπίτι, που ανοίγει την έκθεση και δείχνει ότι όλα είναι δυνατά. Σχεδιασμένο από την Καλιφορνέζα αρχιτέκτονα Μισέλ Κάουφμαν, διαθέτει συρόμενα πανέλα για να ρυθμίζεται το φως του ήλιου και ο αέρας, πατώματα από μπαμπού, ανακυκλωμένα μη τοξικά υλικά και συστήματα εξοικονόμησης νερού και ενέργειας. Η έκθεση παρουσιάζει άλλα 20 «πράσινα» σπίτια από όλο τον κόσμο, όμως οι οργανωτές της επιμένουν ότι δεν είναι απαραίτητο να φτιάξεις ένα ολόκληρο «πράσινο» σπίτι για να κάνεις κάτι καλό για το περιβάλλον. «Μπορείς να ξεκινήσεις σιγά σιγά, προσθέτοντας στο ήδη υπάρχον σπίτι σου κάποια πράσινα χαρακτηριστικά. Μπορείς να το κάνεις σταδιακά και με πολύ στυλ», λέει ο υπεύθυνος Ντόναλντ Αλμπρεχτ.

Φιλικά στο περιβάλλον

Από πού να ξεκινήσεις, όμως; Εδώ μπαίνει το Κέντρο Πηγών της έκθεσης... Σε αυτό, ο επισκέπτης μπορεί να γνωρίσει 60 διαφορετικά υλικά φιλικά προς το περιβάλλον, να τα αγγίξει και να μάθει γι’ αυτά. Εκεί επίσης θα του δοθούν συμβουλές, μοντέλα και διαγράμματα για το πώς να τα υιοθετήσει στο δικό του σπίτι. Μιλάμε για πατώματα από φελλό, πλακάκια από ανακυκλωμένο αλουμίνιο και γυαλί, ακόμη και για τουαλέτες με διπλή επιλογή στο καζανάκι (μικρό–μεγάλο).

Αυτό που ουσιαστικά θέλουν να επιτύχουν οι διοργανωτές είναι να πείσουν τους επισκέπτες της έκθεσης για τα πλεονεκτήματα αλλά και την ευκολία του να φτιάξεις ένα –φιλικό προς το περιβάλλον αλλά και την υγεία σου– σπίτι. Και περισσότερο από όλα, όπως λέει ο Αλμπρεχτ, να τους πείσουν πως «το να γίνεις “πράσινος”, δεν σημαίνει να γίνεις αλλόκοτος ή γραφικός»...
