NEW YORK - A well-organized tropical wave in the Atlantic Ocean about 250 miles east of the Windward Islands has formed into a tropical depression, the U.S. National Hurricane Center said late today. The NHC sent an Air Force hurricane hunter airplane to investigate the system early this afternoon to confirm if a depression had formed. It would be the sixth tropical depression of the 2007 Atlantic hurricane season.

LSU professor looks for life in and under antarctic ice
August 31, 2007 02:01 PM - Louisiana State University

Antarctica is home to the largest body of ice on Earth. Prior to approximately 10 years ago, no one thought that life could exist beneath the Antarctic ice sheets, which can be more than two miles thick in places, because conditions were believed to be too extreme. However, Brent Christner, assistant professor of biological sciences at LSU, has spent a great deal of time in one of the world’s most hostile environments conducting research that proves otherwise. Christner’s discoveries of viable microbes in ancient ice cores and subglacial environments coupled with the realization that large quantities of liquid water exist beneath the Antarctic ice sheet have changed the way biologists view life in Antarctica.

TORONTO - Canada's fledgling wind power industry, late off the global starting blocks, has stumbled on growing local resistance to the idea of massive turbines dotting the country's relatively unmarked landscape. Although polls show widespread support for the renewable energy source, a growing number of companies say that support quickly fades among those who must live alongside wind farms, leading to project delays and extra costs.

Spreading deserts threaten world food supply

Spreading deserts and degradation of farm land due to climate change will pose a serious threat to food supplies for the world's surging population in coming years, a senior United Nations scientist warned on Friday. M.V.K. Sivakumar of the U.N.'s World Meteorological Organisation (WMO) said the crunch could come in just over a decade as all continents see more weather-related disasters like heat waves, floods, landslides and wildfires.

More than half China's 1.3 billion population, including 278 cities, live without any form of sewage treatment, state media said on Friday, quoting city planning officials. And eight of those cities have populations of more than 500,000, Zhao Baojiang, chairman of the China association of city planning, was quoted as saying. In its rapid development into the world's fourth-largest economy, China has been struggling to curb horrific water and air pollution.

Hydrologists To Study Climate Change Effects On Sierra Lakes
August 30, 2007 02:34 PM - UC Riverside

RIVERSIDE, California - Researchers will try to understand how climate change affects the rate of atmospheric deposition of nutrients - elements or compounds essential to the growth and survival of organisms - in mountain lakes. They'll also be looking at how increases in the deposition of such nutrients threaten the lakes' plant and animal species. Fossil fuel combustion by humans has multiple effects, one of which - an increase in greenhouse gas emissions - results in climate change and an increase in atmospheric pollutants such as nitrogen. More available nitrogen, in turn, results in increased atmospheric nitrogen deposition.

Spain Warns Of Virus Threatening Dolphins

MADRID - Spain has asked authorities around the Mediterranean and adjoining seas for help in monitoring an infection which threatens a protected species of dolphin, warning it may become an epidemic. "The virus identified is practically the same one which provoked a massive epidemic in the 1990s and could affect other species of the whale family, such as pilot whales,"the Environment Ministry said in a statement late on Wednesday.
