Russia says has no plans to cap carbon emissions
April 29, 2008 09:45 AM - Reuters
Russia will not accept binding caps on its greenhouse gas emissions under a new climate regime, currently being negotiated to succeed the Kyoto Protocol after 2012, top officials said on Monday. Kyoto puts a cap on the average, annual greenhouse gas emissions from 2008-12 for some 37 industrialized countries, including Russia.
Desalination Raises Environmental, Cost Concerns
April 29, 2008 09:42 AM - Ben Block, Worldwatch Institute
As global freshwater reserves dry up, desalination plants are receiving greater attention as an option for providing both drinking water supplies and agricultural irrigation. But a new study released on Thursday raises several concerns about the environmental impact and cost effectiveness of the widely touted technology to convert seawater to fresh water. Desalination plants pose a risk to marine species when the water is collected from ocean areas, as well as when the salty discharge is deposited into coastal estuaries, according to the report, which was released by the U.S. National Research Council (NRC).
Emissions irrelevant to future climate change?
April 28, 2008 07:16 AM - BioMed Central
Climate change and the carbon emissions seem inextricably linked. However, new research published in BioMed Central’s open access journal Carbon Balance and Management suggests that this may not always hold true, although it may be some time before we reach this saturation point. The land and the oceans contain significantly more carbon than the atmosphere, and exchange carbon dioxide with the atmosphere.

A Sudanese climate researcher has been honoured by the UN Environment Programme in recognition of her work on climate change and adaptation in conflict-stricken Darfur. Balgis Osman-Elasha, a senior researcher at Sudan's Higher Council for Environment and Natural Resources, was presented with a 'Champions of the Earth 2008' award this week (22 April), along with six other awardees from Bangladesh, Barbados, Monaco, New Zealand, United States and Yemen.
Human warming hobbles ancient climate cycle
April 28, 2008 06:07 AM - Reuters
WASHINGTON (Reuters) - Before humans began burning fossil fuels, there was an eons-long balance between carbon dioxide emissions and Earth's ability to absorb them, but now the planet can't keep up, scientists said on Sunday. The finding, reported in the journal Nature Geoscience, relies on ancient Antarctic ice bubbles that contain air samples going back 610,000 years.
Plan to reverse global warming could backfire
April 25, 2008 05:15 AM - Reuters
CHICAGO (Reuters) - A proposed solution to reverse the effects of global warming by spraying sulfate particles into Earth's stratosphere could make matters much worse, climate researchers said on Thursday. They said trying to cool off the planet by creating a kind of artificial sun block would delay the recovery of the Antarctic ozone hole by 30 to 70 years and create a new loss of Earth's protective ozone layer over the Arctic.
Timeline for Irreversible Climate Change
April 23, 2008 09:20 AM - James Hansen, The World Business Council for Sustainable Development (WBCSD)
Fifty years ago, Yankee Stadium had about 70,000 seats. It seldom sold out, and almost any kid could afford the cheapest seats. Capacity was reduced to about 57,000 when the stadium was remodeled in the 1970s. Most games sell out now, and prices have gone up. The new stadium, opening next year, will reduce seating to about 51,800.
Security risk from climate said underestimated
April 23, 2008 05:30 AM - Reuters
LONDON (Reuters) - Countries around the world have hugely underestimated the potential conflicts stemming from climate change and must invest heavily to correct that mistake, a report said on Wednesday. The report for Britain's Royal United Services Institute (RUSI) by environment expert Nick Mabey said the response had been "slow and inadequate" and to rectify it spending needed to surge to levels comparable to sums spent on counter-terrorism.
Report confirms ozone pollution can kill
April 22, 2008 07:01 PM - Reuters
WASHINGTON (Reuters) - Even breathing in a little ozone at levels found in many areas is likely to kill some people prematurely, the National Research Council reported on Tuesday. The report recommends that the Environmental Protection Agency consider ozone-related mortality in any future ozone standards, and said local health authorities should keep this in mind when advising people to stay indoors on polluted days.
As Earth Day Arrives, Population Still the Uneasy Issue
April 22, 2008 09:20 AM - , Worldwatch Institute
NEW ORLEANS-People walking around the Sheraton Hotel here are talking about population as if it were the most natural conversation in the world. The topic interests me, so I join in. As it happens, I've written a book on it, just published by Island Press, which I don't shrink from mentioning. Just being here, though, reminds me that human numbers aren't often talked about outside this hotel.
