"Today, the State Council announced that China will commit to reduce its carbon dioxide emissions per unit of GDP, or carbon intensity, by 40 to 45 percent of 2005 levels by 2020. It was also announced separately by the Ministry of Foreign Affairs that Premier Wen Jiabao (also the chair of the State Council, and pictured right, showing what President Hu meant by a "notable margin"…at least in my imagination) will attend the Copenhagen climate conference that begins in less than two weeks."

"Most of the chemical absorption of sound occurs at relatively low frequencies, from about 1,000 to 5,000 hertz. Propeller noise ... fall in the same range, as does some military and research sonar. So this "background" noise, especially prevalent near shipping lanes, will be louder. That may be bad news for marine mammals, which use sounds in the same range for communication and echolocation while foraging. "We're not saying that during the next 100 years all dolphins will be deafened," Dr. Zeebe said. "But the background noise could essentially override or mask the sounds that they're depending on."

"Studying past climates can help scientists predict how the planet will change in the future. Using historical data, scientists at the University of Bristol, have developed a new model of climate change they believe is more accurate than previous estimates. Leaving certain data out of climate models, researchers discovered, has led to exceedingly modest estimates of the effect of carbon emissions on the planet."

New research shows that the 2010 Amazon drought may have been even more devastating to the region's rainforests than the unusual 2005 drought, which was previously billed as a one-in-100 year event.

The world's coral reefs are in danger of dying out in the next 20 years unless carbon emissions are cut drastically, warns a coalition of scientists led by Sir David Attenborough.

"Confidential UN analysis shows that if the current offers on the table at the Copenhagen climate summit are agreed, global temperatures will rise on average by 3C."

"But some positive news from the biggest developing nations--China, India, and Brazil--have encouraged the proceedings. Each has pledged to reduce carbon emissions on some level, and Obama has put forward an emissions reduction target based on the climate bill that passed the House of Representatives last summer. At 17% below 2005 levels, it's hardly what the international community was looking for--but it's progress nonetheless. Most importantly, hope seems to be in the air--real progress can be made in the coming days."

Stunning graphic that shows where emissions come from the in the world. A few countries put out most of the emissions in the world.

"10:10 Campaign Director Eugenie Harvey responded to the news by saying, 'Today's announcement from the Tories is truly remarkable. This would mean that all central Government buildings, from Big Ben to Belmarsh Prison will follow the inspiring example set by families, businesses, schools, and faith groups across the country in making an ambitious 10% emissions reduction in 2010.'"

"Degraded peatlands contribute to almost 50% of Indonesia's GHG emissions; yet development in peatlands probably contribute less than 1 % to the national economy (GDP)."

"More Americans believe steps taken to reduce global warming pollution will help the U.S. economy than say such measures will hurt it. It's a sign the public is showing more faith in President Barack Obama's economic arguments for limiting heat-trapping gases than in Republican claims that the actions would kill jobs."

Experts warn that Scotland's targets on cutting emissions will be hard to achieve without a wider international agreement.

"We know, for example, that Portland has actually reduced its aggregate carbon emissions since 1990 despite growing 18 percent in population, largely due to land-use and transportation strategies that stress infill locations, walkable neighborhoods, and transit-oriented development."

A lot depends on how 'peat' and 'natural forest' are defined and how rights are agreed upon. Strong lobbies from the forest and tree-crop plantation industry argue that the economy will be harmed if 'business as usual' is interrupted. According to news sources, definitions of 'natural forest' and 'peat' differ between drafts prepared by the Indonesian Government's emissions reduction taskforce and by the Ministry of Forestry. There are several key issues that need to be resolved.

"Mangroves are so efficient at keeping carbon dioxide out of the atmosphere that when they are destroyed, they release as much as 10 percent of all emissions worldwide attributable to deforestation -- even though mangroves account for just 0.7 percent of the tropical forest area, researchers said."
