Earth's oceans are vast reservoirs of carbon dioxide (CO2) with the potential to control the pace of global warming.

West Antarctica Key to Missing Ice
August 31, 2009 07:58 AM - Roger Greenway, ENN

Assessing the changing climate on Earth is not easy. Much depends on data that can be used to infer past climatic conditions. No one really knows for sure since there were no weather stations or written records. New research by scientists at UC Santa Barbara indicates a possible Antarctic location for ice that seemed to be missing at a key point in climate history 34 million years ago. The research, which has important implications for climate change, is described in a paper published today in Geophysical Research Letters, a journal of the American Geophysical Union.

10,000 Homes Threatened in Los Angeles FIres

The unstoppable Angeles National Forest fire threatened 10,000 homes Saturday night as it more than tripled in size and chewed through a rapidly widening swath of the Crescenta Valley, where flames closed in on backyards and at least 1,000 homes were ordered evacuated. Sending an ominous plume of smoke above the Los Angeles Basin, the fire was fueled by unrelenting hot weather and dense brush that has not burned in 60 years.

Renewable Energy Needs Land, Lots Of Land
August 28, 2009 11:23 AM - Christopher Joyce, NPR

Pending climate and energy legislation puts a lot of stock — and money — into switching from fossil fuels, like coal and oil, to renewable energy such as wind, solar and ethanol. But some new analysis by environmental experts shows that alternative energy comes with some stiff penalties. For example: Energy Sprawl.

Nitrous oxide fingered as monster ozone slayer
August 28, 2009 11:14 AM - Janet Raloff, Science News

New calculations indicate that nitrous oxide has risen to become the leading threat to the future integrity of stratospheric ozone, Earth’s protective shield against the sun’s harmful ultraviolet rays.

Sun Spot-Climate Link

Small changes in the energy output of the sun can have a major impact on global weather patterns, such as the intensity of the Indian monsoon, that could be predicted years in advance, a team of scientists said.

Global Warming Warps Marine Food Webs
August 27, 2009 11:32 AM - Erik Stokstad, ScienceNOW Daily News

Teasing apart the complex ways in which global warming will affect ocean life has been tough. But new research suggests that a simple ecological theory may explain at least one piece of the puzzle: the effect on marine food webs. And the news may not be all bad.

Emissions Reduction Targets of Largest Companies Fail to Meet Scientific Standards
August 27, 2009 08:20 AM - SocialFunds.com via, The World Business Council for Sustainable Development (WBCSD)

Report from the Carbon Disclosure Project analyzes emissions reduction targets of the world's 100 largest companies, and warns that targets are insufficient to meet scientific guidelines.

The Key to Safe Subsurface Storage of CO2
August 25, 2009 01:34 PM - Roger Greenway, ENN

Oil exploration and production technology may hold the key to secure CO2 storage, a report published by the CO2 Capture Project (CCP) today highlights. The report provides a definitive treatment of the CO2 storage subsurface technical issues and how oil and gas experience technology and protocols are available now to address them.
