Australia's forests key to fighting global warming

Ancient Australian forests are key to fighting climate change and contain the world's most dense carbon store, eclipsing tropical rainforests as efficient greenhouse gas absorbers, scientists said on Tuesday.

Sediment yields climate record for past half-million years

Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years. The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles that occurred during that period. New research was presented June 15th at the Chapman Conference on Abrupt Climate Change at Ohio State University's Byrd Polar Research Center. The meeting is jointly sponsored by the American Geophysical Union and the National Science Foundation. Harunur Rashid, a post-doctoral fellow at the Byrd Center, explained that experts have been trying to capture a longer climate record for this part of the ocean for nearly a half-century. "We've now generated a climate record from this core that has a very high temporal resolution, one that is decipherable at increments of 100 to 300 years," he said.

Major shift in US climate policy sparks hope for global treaty

The United States is no longer insisting that China and other large developing countries must make cuts in their greenhouse gas emissions under proposals tabled by the Obama administration for a new global treaty to combat climate change. In a major shift in US policy, reflecting the views of President Obama, Dr Jonathan Pershing who was in Beijing this week for talks with Chinese officials made it clear that this would not require countries such as China to make cuts, merely to carry out actions .

The Chinese gateway to the ancient Silk Road is being flooded – and the culprit, researchers say, is climate change.

Water in Africa – Business turns on the tap

Business is stepping in where governments fail to provide clean water in Africa, with Coca-Cola, SABMiller and major platinum miners leading the way. A world running short of water is presenting a new category of risk to businesses that few have begun to appreciate. That was the warning from campaigner WWF and noted research body the Pacific Institute, at the World Water Forum in Istanbul in late March.

Reviving American Chestnut Trees May Mitigate Climate Change
June 15, 2009 05:45 AM - ScienceDaily

A Purdue University study shows that introducing a new hybrid of the American chestnut tree would not only bring back the all-but-extinct species, but also put a dent in the amount of carbon in the Earth's atmosphere.

Arctic Sea Ice Extent Trending Below Record 2007 Melt

The annual melting of Arctic sea ice is trending toward another record-low. While it's still too early to say whether the 2009 melt will exceed the record 2007 melt -- the annual low-point isn't reached until September -- the trend line for 2009 for the first time has dipped below 2007, according to the latest data from the National Snow and Ice Data Center.

Energy Secretary Steven Chu announced on Friday plans to restart the country's first clean coal power project, scrapped by the previous Bush administration as too expensive. Under an agreement with the non-profit FutureGen Alliance, the Energy Department will take the first steps toward developing the first U.S. commercial scale-carbon capture and storage project, to be located in Mattoon, Illinois.
