High human impact ocean areas along US West Coast revealed
May 11, 2009 10:23 AM - National Science Foundation

"Every single spot of the ocean along the West Coast," said Ben Halpern, a marine ecologist at the National Center for Ecological Analysis and Synthesis (NCEAS) at the University of California at Santa Barbara, "is affected by 10 to 15 different human activities annually." In a two-year study to document the way humans are affecting the oceans in this region, Halpern and colleagues overlaid data on the location and intensity of 25 human-derived sources of ecological stress, including climate change, commercial and recreational fishing, land-based sources of pollution and ocean-based commercial activities. With the information, they produced a composite map of the status of West Coast marine ecosystems.

Drought, Politics Trouble Farmers In California
May 11, 2009 09:12 AM - John McChesney, NPR

California is in its third year of drought, and many farmers in the state's crop-rich Central Valley are looking at dusty fields, or worse, are cutting down their orchards before the trees die.

Survey Of Ocean Climate May Improve Climate Predictions
May 11, 2009 06:14 AM - ScienceDaily

A research team from the Nansen Environmental and Remote Sensing Center, and the Bjerknes Centre for Climate Research, both in Bergen, Norway, has studied observed anomalies in ocean climate, and identified the anomalies' progression with the circulation of the Nordic Seas, and the Norwegian Sea in particular.

In the Antarctic, a Huge Iceberg is About to Break off Glacier
May 10, 2009 07:31 AM - Felicity Ogilvie for The World Today

A massive iceberg with enough freshwater in it to fill Sydney Harbour 135 times over is about to break off the Mertz glacier in Antarctica. The iceberg will be 75 kilometres long and contains 750,000 gigalitres of ice which is apparently quite a lot. Scientists are not sure if it is a natural event or if global warming is to blame. But a joint Australian and French team hope to find out.

Endangered Species Act Cannot be Used in Global Warming Response
May 9, 2009 08:00 AM - ANDREW C. REVKIN, The New York Times

The Obama administration said Friday that it would retain a wildlife rule issued in the last days of the Bush administration that says the government cannot invoke the Endangered Species Act to restrict emissions of greenhouse gases threatening the polar bear and its habitat.

Ice Flood in Alaska

An ice jam that suddenly gave way on Alaska's mighty Yukon River sent floating ice chunks the size of homes into the town of Eagle, knocking some buildings off their foundations and damaging others. The city and neighboring Eagle Village had earlier been flooded by the ice jam, which had backed up river water. The ice jam had kept water nearly 20 feet over the river's flood levels on Wednesday. The Yukon's flood levels at Eagle, about 200 miles east of Fairbanks, was 34 feet.

US EPA Budget Proposal Issued Today

Administrator Lisa P. Jackson released EPA’s fiscal year 2010 budget blueprint, which takes significant strides to ensure that our air, land, and water are safe and clean. Expanding on the investments of the American Recovery and Reinvestment Act, this $10.5 billion budget is designed so EPA can develop programs that are good for the environment, and also aid in the economic recovery.

Sea Salt Holds Clues To Climate Change
May 7, 2009 06:37 AM - ScienceDaily

We know that average sea levels have risen over the past century, and that global warming is to blame. But what is climate change doing to the saltiness, or salinity, of our oceans? This is an important question because big shifts in salinity could be a warning that more severe droughts and floods are on their way, or even that global warming is speeding up.
