Fish Fry: How Will a Warming World Impact U.S. Trout Populations?
Posted by Washington Post: Juliet Eilperin on March 4th, 2010
Scientific American: Dear EarthTalk: A fisherman friend of mine told me that trout populations in the interior West of the U.S. are already shrinking due to global warming. Is this true? And what is the long term prognosis for the trout? --Jon Klein, Portsmouth, N.H. Most scientists agree that the effects of global warming are starting to show up all around the world in many forms. Throughout America's Rocky Mountain West, rivers and streams are getting hotter and drier, presenting new challenges ...

United States: Glacier melting a key clue to tracking climate change

Reuters: The world has become far too hot for the aptly named Exit Glacier in Alaska. Like many low-altitude glaciers, it's steadily melting, shrinking two miles over the past 200 years as it tries to strike a new balance with rising temperatures. At the Kenai Fjords National Park south of Anchorage, managers have learned to follow the Exit and other glaciers, moving signs and paths to accommodate the ephemeral rivers of blue and white ice as they retreat up deeply carved ...
EU drafts reveal biofuel’s environmental damage
Posted by Washington Post: Juliet Eilperin on March 4th, 2010
Reuters: Biodiesel and other "green" fuels that Europeans put in their cars can have unintended consequences for tropical forests and wetlands, European Union reports show -- the first evidence of EU misgivings. The EU aims for its 500 million citizens to get about a tenth of their road fuels from renewable sources such as biofuels by 2020, but some EU officials want the target reduced in a review in four years time. Modelling exercises are starting to show unwanted impacts spreading ...
Australia: The big dry ahead
Posted by Washington Post: Juliet Eilperin on March 4th, 2010
Australian Broadcasting Corporation: The Department of Water says a report on Western Australia's future water supply presents significant challenges. The CSIRO report found water levels in south western WA will fall by an average of 25 per cent by 2030 but it is predicting they could possibly fall by half. The report blames climate change since the mid 1970s for a big drop in rainfall and surface and groundwater yields. It says as a result, once abundant wetlands and perennial streams have, in the worst ...
