NEW YORK (Reuters) - The La Nina weather anomaly is gathering steam and will possibly strengthen in the next three months, the U.S. Climate Prediction Center predicted Thursday. In its monthly update, the center said conditions in the equatorial Pacific already reflected La Nina, in which waters in the area become cooler than normal. In the more famous El Nino phenomenon, waters in the Pacific turn abnormally warm and cause havoc around the Asia Pacific rim.

Biodiversity requires global monitoring mechanism
September 6, 2007 08:05 AM - , SciDevNet

Biodiversity has received increasing attention from scientists, governments and the public since the 'Earth Summit' at Rio de Janeiro and the establishment of the international Convention on Biological Diversity (CBD) in 1992. There are local conservation successes to celebrate as a result, but global threats to biodiversity are still on the rise.

Hurricane Henriette Bears Down On Mainland Mexico

LOS CABOS, Mexico (Reuters) - Hurricane Henriette roared toward farming states in mainland Mexico on Wednesday, threatening heavy rain and winds for large corn and tomato crops after pummeling the Pacific beach resort of Los Cabos. Henriette, a relatively weak Category 1 storm that killed seven people including a foreign tourist on its route up the Pacific coast, swept into the Gulf of California with maximum sustained winds of 75 mph. Large waves were expected to batter the coastal states of Sonora and Sinaloa, where a storm last year ripped through the tomato crop, pushing up prices blamed for a brief inflation spike.

Delta Ecosystem Collapse: California Must Find an Alternative Water Source Say Fishermen

San Francisco, CA — The most important estuary on the west coast of North and South America is in immediate danger of ecological collapse if water diversions are not sharply cut, a commercial fishing organization warned today. On the heels of a Federal Court decision last Friday in Fresno — ordering a reduction in diversions from the Sacramento-San Joaquin Delta - the Pacific Coast Federation of Fishermen’s Associations (PCFFA) today called on the Governor and Legislature to begin developing alternatives to Delta water in order to save the fish of the estuary and finally provide the state with a reliable water supply.

PRETORIA (Reuters) - Africa will suffer the most if the world fails to reduce global warming, with parts of the impoverished continent becoming uncultivable or uninhabitable, top British government scientists said on Wednesday. In a presentation in Pretoria, David King, the British government's chief scientific adviser, warned climate change, if unchecked, would lead to worsening drought in Africa as well as flooding along much of its coastline. He said an additional 70 million Africans could be at risk of hunger by the 2080s as a result of continued global warming -- temperatures in Africa have risen by about 0.7 degrees Celsius during the last century.

USGS: Florida Aquifers and Drinking Water Supplies Contaminated With Pesticides, VOC's
September 5, 2007 01:06 PM - USGS News Service

TAMPA Fla. - As populations increase around areas with public water-supply wells in the northern Tampa Bay region there are corresponding increases in contamination. According to a study by the U.S. Geological Survey, human activities are polluting ground-water supplies. In the first phase of the study, 30 randomly-selected public-supply wells were sampled prior to treatment and analyzed for the presence of 258 compounds generated by humans such as pesticides and volatile organic compounds. The northern Tampa Bay area was selected for study because a large percentage of the population relies on ground-water resources from the Upper Floridan aquifer for drinking water supply.
