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.

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.
China Warns: Rising Seas Will "Engulf" Tract Of Pearl River Delta
August 30, 2007 12:08 PM - Reuters
BEIJING - A huge swathe of China's booming Pearl River Delta will be "engulfed" by rising sea water by the middle of the century because of global warming, state media said on Thursday, quoting weather officials. Some 1,153 square km (445 square miles) of coastal land would be flooded by 2050, with the bustling cities of Guangzhou, capital of Guangdong province, Zhuhai and Foshan the worst affected, the China Daily said, quoting the provincial water authority.
New U.S. Test: CO2 Could Make Grasslands 'Unusable'
August 30, 2007 10:26 AM - Maryke Steffens, SciDevNet
Increasing atmospheric carbon dioxide levels could change the nature of grasslands and decrease their usefulness as grazing pastures, say researchers. The study was published in the journal Proceedings of the National Academy of Sciences this week (27 August). If carbon dioxide levels in the atmosphere continue to rise, important grazing areas in parts of Africa, Kazakhstan, Mexico, Mongolia, and southern and South East Asia could be under threat, according to lead author Jack Morgan, a plant physiologist from the US Department of Agriculture's Agricultural Research Service.

The iconic river and lakeside scenery that has defined England's beauty through the ages in music, art and literature - from Handel to Turner to Dickens - is being destroyed by our careless use of water and disregard for freshwater habitats.
Low oxygen in coastal waters impairs fish reproduction
August 29, 2007 07:00 AM - University of Texas at Austin
PORT ARANSAS, Texas�Low oxygen levels in coastal waters interfere with fish reproduction by disrupting the fishes� hormones, a marine scientist from The University of Texas at Austin Marine Science Institute has found. Incidents of seasonal low levels of oxygen, known as hypoxia, have increased dramatically in coastal waters throughout the world over the past few decades, largely as a result of increased run-off from human agricultural and industrial activities. Hypoxia�s long-term impact on marine animal populations is unknown.
