Antarctic ice riddle keeps sea-level secrets
January 31, 2008 08:22 AM - Reuters

TROLL STATION, Antarctica (Reuters) - A deep freeze holding 90 percent of the world's ice, Antarctica is one of the biggest puzzles in the debate on global warming with risks that any thaw could raise sea levels faster than U.N. projections. Even if a fraction melted, Antarctica could damage nations from Bangladesh to Tuvalu in the Pacific and cities from Shanghai to New York. It has enough ice to raise sea levels by 57 meters (187 ft) if it melted, over thousands of years.

Canadian provinces eye carbon-trading plan
January 30, 2008 03:21 AM - Reuters

VANCOUVER, British Columbia (Reuters) - Many of Canada provinces are pursuing a carbon-trading plan to fight climate change, saying on Tuesday it was inevitable the country would adopt a such system, even if the current federal government is cool to the idea. British Columbia, Ontario, Quebec and Manitoba have been discussing adopting carbon trading, or emissions credit trading, in conjunction with the Western Climate Initiative (WCI) in the United States, an idea championed by California Gov. Arnold Schwarzenegger.

Russia clears way for carbon profits
January 29, 2008 08:22 AM - Reuters

MOSCOW (Reuters) - Russia's government on Tuesday opened the door to applications from entrepreneurs and big polluters to profit from greenhouse gas emissions cuts by selling these to Western countries. The U.N.'s Kyoto Protocol puts limits on greenhouse gases from 36 rich nations but softens the restrictions by allowing governments to fund emissions-cutting projects in poor and former communist countries and count the cuts as their own.

California asks EPA to regulate machine emissions
January 29, 2008 01:18 AM - Reuters

California officials on Monday called on the U.S. Environmental Protection Agency to regulate greenhouse gas emissions from industrial machines that they say emit as much carbon dioxide as 40 million cars. California Attorney General Jerry Brown, along with officials from four other states, is petitioning the agency to set emissions standards for equipment in the construction, mining and agricultural industries. Earlier this month, California and other states sued the EPA to overturn a Bush administration decision that denied California's attempt to set new standards for auto emissions.

Global Warming by the Numbers
January 26, 2008 10:50 AM - Environmental Defense

Global warming is the most serious environmental threat of our time. As these facts show, affordable options are available. And America cannot afford to fall behind any more in the race to invent clean, renewable energy sources.

Climate change poses a huge threat to human health
January 25, 2008 09:30 AM - BMJ-British Medical Journal

Climate change will have a huge impact on human health and bold environmental policy decisions are needed now to protect the world’s population, according to the author of an article published in the BMJ today. The threat to human health is of a more fundamental kind than is the threat to the world’s economic system, says Professor McMichael, a Professor of public health from the Australian National University. “Climate change is beginning to damage our natural life-support system,” he says.

Europe climate targets strong signal to others: U.N.
January 25, 2008 09:07 AM - Reuters

DAVOS, Switzerland (Reuters) - New European targets for cutting emissions of greenhouse gases are a strong signal to other countries to reduce their carbon output, the U.N. environment chief said on Friday. The European Commission's plan to cut emissions unilaterally by 20 percent by 2010, announced this week, is "quite far-reaching," Achim Steiner, head of the United Nations Environment Program, said at the annual meeting of the World Economic Forum.

Europe transport can meet new emission limits: Barrot
January 25, 2008 08:53 AM - Reuters

The European car and airlines industries should be able to adapt to new plans to slash greenhouse gas emissions, EU Transport Commissioner Jacques Barrot said on Friday. The introduction of electric cars, in particular, should help to cut emissions from journeys within cities, Barrot told Reuters at the annual meeting of the World Economic Forum.

Lofty Himalaya magnify global warming impact
January 25, 2008 04:53 AM - Reuters

DAVOS, Switzerland (Reuters) - The Himalayas are suffering the effects of global warming more acutely because of their height and melting glaciers could flood local settlements, the World Conservation Union (IUCN) said on Thursday. "The Himalaya, that's really moving very fast. They're being hit very hard," IUCN Director General Julia Marton-Lefevre told Reuters at the annual meeting of the World Economic Forum.

Why Diatoms could help stop global warming
January 24, 2008 10:57 AM - University of Washington

The shells of diatoms are so heavy that when they die in the oceans they typically sink to watery graves on the seafloor, taking carbon out of the surface waters and locking it into sediments below. Scientists have reported the discovery of whole subsets of genes and proteins that govern how one species of diatom builds its shell. For oceanographers, the work might one day help them understand how thousands of different kinds of diatoms -- and their ability to remove carbon dioxide from the atmosphere -- might be affected by something like global climate change. Material scientists involved in the work are interested in the possibilities of manipulating the genes responsible for silica production as a way of fabricating more efficient computer chips.
