Aerosols: their part in our rainfall
February 12, 2009 09:29 AM - CSIRO Australia
"We have identified that the extensive pollution haze emanating from Asia may be re-shaping rainfall patterns in northern Australia but we wonder what impact natural and human-generated aerosols are having across the rest of the country," Dr Rotstayn said.
Merged climate, pollution fight seen saving cash
February 12, 2009 09:14 AM - WBCSD
Merging separate fights against air pollution and climate change could save cash and encourage developing nations such as China to do more to curb global warming, researchers said on Wednesday. "There are big gains to be made" from a combined policy, said Petter Tollefsen, a researcher at the Center for International Climate and Environmental Research, Oslo (CICERO).
What a slump in carbon prices means for the future
February 11, 2009 05:46 PM - New Scientist
It is getting progressively cheaper to pollute the atmosphere. The price of permits to emit carbon dioxide has crashed, falling to 9.30 euros ($12) per tonne of CO2 on Tuesday, close to the all-time low of 8 euros. In the medium to long term, this might affect the European Union's ability to meet its ambitious targets for reducing emissions by 20% by 2020 relative to 1990 levels. A low price is bound to have more immediate effects too.
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.
