Black Carbon an Easy Target for Climate Change
February 11, 2009 11:19 AM - Policy Innovations

Could the silver bullet for climate change be black? The particulate matter called black carbon—a type of soot from burning fossil fuels, biofuels, and biomass—is now estimated to be the second most potentgreenhouse warming agent after carbon dioxide. As a result, reduction of black carbon has gained momentum as one of the fastest means to significantly impact global warming.

U.S. stimulus would cut climate emissions: report
February 9, 2009 09:50 AM - Reuters

WASHINGTON (Reuters) - Energy efficiency and conservation proposals in President Barack Obama's original economic stimulus plan would cut climate-warming carbon dioxide emissions by 61 million tonnes a year, a new report says. That would be equivalent to eliminating the greenhouse gas emissions from electricity used in 7.9 million U.S. homes or taking 13 million cars off the road, the analysis of the recovery plan's carbon footprint found on Thursday.

U.S. Leaders Support Law of the Sea Treaty
February 9, 2009 09:46 AM - Worldwatch Institute

Newly appointed U.S. leadership is promising to join a longstanding international agreement that oversees ocean resource and pollution disputes. During last week's Cabinet confirmation hearings, leaders in both the U.S. Senate and the administration of newly elected President Barack Obama conveyed support for the treaty, known as the United Nations Law of the Sea Convention, suggesting an end to decades of dispute over U.S. accession.

Clearing the air with China
February 9, 2009 09:10 AM - LA Times

As President Obama pursues green infrastructure projects and other programs aimed at fighting climate change, he is eventually going to have to confront an unpleasant truth: None of it will matter unless the developing world, particularly China, does the same. With China having passed the U.S. as the country with the highest greenhouse gas emissions in the world, and with its per-capita emissions rising four to six times faster than ours, any carbon reductions here will be more than canceled out by increases there.

Food: the next frontier in recycling
February 9, 2009 08:49 AM - MPR

It turns out a lot of what we throw in the garbage is stuff that could be composted. Stuff like food scraps, used Kleenex and greasy pizza cartons. In Duluth, the Sanitary District runs a compost site that turns 50-foot-long piles of anything you can think of into compost. The district's Susan Darley-Hill calls these piles "windrows" because they look like giant rows of hay, only brown. It takes a couple of days to put together enough material to make these windrows, and each one has a small electric pump at the end to force air through it.

Climate issues emerging as new focus for U.S. and China
February 6, 2009 09:03 AM - WBCSD

When Chinese officials and the administration of President Barack Obama begin discussions in earnest over issues at the heart of relations between the United States and China, the usual suspects will no doubt emerge: trade, human rights, Taiwan. But increasingly, officials and scholars from both countries say, the global problem of climate change could become another focal point in the dialogue.

U.S. May Not Match Europe’s Pledge on Carbon Cuts, De Boer Says
February 5, 2009 11:35 AM - Bloomberg

Feb. 4 (Bloomberg) -- U.S. President Barack Obama is unlikely to match a European Union pledge to cut greenhouse-gas emissions by as much as 30 percent from 1990 levels because it’s too ambitious, United Nations Climate Chief Yvo de Boer said.

More Extreme Weather In The Arctic Regions
February 5, 2009 10:55 AM - University of Bergen

A new study published in Climate Dynamics by Erik Kolstad and Thomas J. Bracegirdle reveals that one of the most visible signs of climate change is the dramatically reduced ice cover in the Arctic. The retreat of the sea ice leads to rapid changes in the weather conditions in these areas. The study reveals that regions that have been covered by sea ice until now will be exposed to new kinds of severe weather. This may have dire consequences for human activities in the Northern regions.

US states may regain control of vehicle emissions
February 5, 2009 09:23 AM - New Scientist

PRESIDENT Barack Obama is cleaning up after George W. Bush. Within a week of taking office, Obama ordered the US Environmental Protection Agency (EPA) to reconsider Bush's policy of banning states from implementing their own standards for tailpipe emissions.

Insecticide chemical is a powerful greenhouse gas.
February 2, 2009 09:37 AM - The Environment Report

The federal government is going to take some significant steps to reduce global warming gases. Carbon dioxide is the main target, but there are other types of greenhouse gases. Lester Graham spoke with one researcher who found a potent greenhouse gas lingers in the atmosphere much longer than previously thought:
