The critical role of forests as massive "sinks" for absorbing greenhouse gases is "at risk of being lost entirely" to climate change-induced environmental stresses that threaten to damage and even decimate forests worldwide, according to a new report released today. The report will be formally presented at the next session of the United Nations Forum on Forests (UNFF) taking place 20 April-1 May 2009 at the UN Headquarters in New York City.

"It's hard to believe that this is what’s melting the glaciers," said Dr. Veerabhadran Ramanathan, one of the world’s leading climate scientists, as he weaved through a warren of mud brick huts, each containing a mud cookstove pouring soot into the atmosphere.

With Earth Day only a few days away, the U.S. Environmental Protection Agency (EPA) is kicking off the 2009 "Change the World, Start with Energy Star" campaign to educate kids and their families about how to save money and fight climate change through energy efficiency.

Sea levels could rise by a "catastrophic" 10 feet by the end of the century – putting millions of people at risk of flooding with coastal cities such as London, New York, Tokyo and Calcutta submerged, according to a new study.

U.S. EPA Administrator Lisa P. Jackson is scheduled to lead the U.S. delegation to the Group of Eight Environment Ministers Meeting held this year in Siracusa, Italy. This marks her first international trip as EPA Administrator. Administrator Jackson will represent the United States among Environment Ministers from the Group of Eight (Italy, France, Germany, the United Kingdom, the United States, Japan, Canada, and Russia) as well as 12 additional Environment Ministers and leaders of international organizations from around the world.

When procuring just about anything, it makes sense to get as close to the source as possible. That’s the idea behind an ambitious plan to harvest solar energy from outer space, then beam the electricity back to Earth.

Ethanol production in Minnesota and Iowa uses far less water overall than similar processes in states where water is less plentiful, a new University of Minnesota study shows. The study, which will be published in the April 15 edition of the journal Environmental Science and Technology, is the first to compare water use in corn-ethanol production on a state-by-state basis. The authors used agricultural and geologic data from 2006-2008 to develop a ratio showing how much irrigated water was used to grow and harvest the corn and to process it at ethanol plants. Among the major ethanol-producing states, Iowa uses the least water, with about six gallons of water used for each gallon of ethanol. Minnesota, which in 2007 produced roughly a third as much ethanol as Iowa, uses about 19 gallons of water per ethanol gallon.

The U.S. Environmental Protection Agency has released the national greenhouse gas inventory, which finds that overall emissions during 2007 increased by 1.4 percent from the previous year. The report, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2007, is the latest annual report that the United States has submitted to the Secretariat of the United Nations Framework Convention on Climate Change, which sets an overall framework for intergovernmental efforts to tackle the challenge posed by climate change.

The United States Environmental Protection Agency announced steps to protect U.S. waters from the threat of ocean acidification under the Clean Water Act. Today, EPA issued a notice of data availability to be published in the Federal Register that calls for information and data on ocean acidification that the agency will use to evaluate water-quality criteria under the Clean Water Act. The notice responded to a formal petition and threatened litigation from the Center for Biological Diversity that sought to compel the agency to impose stricter pH criteria for ocean water quality and publish guidance to help states protect American waters from ocean acidification. EPA's notice marks the first time that the Clean Water Act will be invoked by the agency to address ocean acidification.

Guardian poll reveals almost nine out of 10 climate experts do not believe current political efforts will keep warming below 2C

Malaysia's Muslim preachers have been enlisted in the fight for wildlife conservation, using passages from the Koran to raise awareness and help protect some of the world's most endangered species. After a successful campaign last year, when more than 400 mosques in the state of Terengganu held sermons focusing on turtle conservation issues, WWF decided to extend the project to support efforts to tackle poaching.

It's not easy to kill a full-grown tree — especially one like the piñon pine. The hardy evergreen is adapted to life in the hot, parched American Southwest, so it takes more than a little dry spell to affect it. In fact, it requires a once-in-a-century event like the extended drought of the 1950s, which scientists now believe led to widespread tree mortality in the Four Corners area of Utah, Colorado, New Mexico and Arizona. So, when another drought hit the area around 2002, researchers were surprised to see up to 10% of the piñon pines die off, even though that dry spell was much milder than the one before. The difference in 2002 was the five decades of global warming that had transpired since the drought in the 1950s.

NASA satellite data and a new modeling approach could improve weather forecasting and save more lives when future cyclones develop. About 15 percent of the world's tropical cyclones occur in the northern Indian Ocean, but because of high population densities along low-lying coastlines, the storms have caused nearly 80 percent of cyclone-related deaths around the world. Incomplete atmospheric data for the Bay of Bengal and Arabian Sea make it difficult for regional forecasters to provide enough warning for mass evacuations. In the wake of last year's Cyclone Nargis -- one of the most catastrophic cyclones on record -- a team of NASA researchers re-examined the storm as a test case for a new data integration and mathematical modeling approach. They compiled satellite data from the days leading up to the May 2 landfall of the storm and successfully "hindcasted" Nargis' path and landfall in Burma.

Networking company Cisco is spearheading efforts to develop technology that can manage energy conservation and carbon footprints by collecting and processing field data. The company uses wireless networking to monitor the changing environment to track emissions from the threatened Brazilian rainforest to the Golden Gate Bridge.

For the Inupiat people of northern Alaska, whales are a way of life. These people eat the animals. They worship them. They organize their calendars around them. And on and on. It's been that way for thousands of years. Now, however, climate change is pushing the whales further north, making it harder for the Inupiat to catch them. That environmental shift is threatening the culture's fundamental roots.

Elephant seals equipped with electronic tags and robotic mini submarines using sonar were just two projects during the International Polar Year (IPY) that aimed to investigate the effects of global warming in polar regions.

The world’s largest gas producer and the world’s largest natural-gas market have finally come together. Gazprom and Shell announced a deal that will send gas from Russia’s far east to LNG terminals on the U.S. West Coast.

The global warming situation has become so dire that Barack Obama's chief scientific adviser has raised with the president the possibility of massive-scale technological fixes to alter the climate known as 'geo-engineering'. John Holdren, who is a member of the president's cabinet, said today the drastic measures should not be "off the table" in discussions on how best to tackle climate change. While his office insisted that he was not proposing a dramatic switch in policy, Holdren said geo-engineering could not be ruled out.

A cheap solar cooker has won $75,000 prize in a contest for green ideas. The cooker could sterilize water and could help 3 billion poor people cut greenhouse gases, and fight global warming.

The 20,000 residents of tiny, vulnerable Mousuni Island in the Indian Sundarbans are using technology to protect themselves from climate change-related threats – including deadly cyclones and rising sea levels – now impacting more and more severely upon them.
