Great Lakes Ecosystems Threatened by Food Scarcity
2013-12-12 20:45:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Declines of the food resources that feed lake organisms are likely causing dramatic changes in the Great Lakes, according to a new U.S. Geological Survey (USGS) study. USGS scientists and partners found that since 1998, water clarity has been increasing in a majority of the Great Lakes, while phytoplankton (the microscopic water organisms that feed all other animals), native invertebrates and prey fish have been declining. These food web changes fundamentally affect the ecosystems valuable resources...

Scientists Seek Origin of Deadly Disease Plaguing Great Lakes Waterfowl
2013-11-27 19:33:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Researchers have developed a new way to track a deadly disease wreaking havoc on the water bird population of the Great Lakes region. Type E botulism is a neuromuscular disease caused when birds ingest infected fish. With 10,000 more waterfowl dying in 2007 from the sickness compared to when it was first reported 50 years ago, ocean engineers from the Florida Atlantic University Institute for Ocean Systems Engineering have teamed up with the US Geological Survey in order to track waterfowl carcasses...

Tar Sands Industry Eyes Great Lakes for Cheap Shipping
2013-11-22 17:39:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: As tar sands extraction continues and proposals for expanded pipelines from Canada into the U.S. form a backdrop, the Great Lakes themselves could become the next frontier for moving crude oil to a vast Midwest refinery network. The region faces a critical choice about whether the Great Lakes should become a thoroughfare for tar sands crude shipping, a new report from Alliance for the Great Lakes warns. The report, Oil and Water: Tar Sands Crude Shipping Meets Great Lakes?, finds that neither...

Great Lakes Recover Substantial Water Levels
2013-11-21 05:08:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: Water levels in the Great Lakes, which reached historic lows earlier this year, have recovered substantially because of heavy snowfall and spring rains, government scientists said. Lakes Michigan and Huron saw a 20-inch rise this yearnearly twice the normal amount, said Keith Kompoltowicz, who monitors the lakes for the Army Corps of Engineers. Levels remain below long-term averages in some of the lakes, and it is hard to predict whether the gains will hold, said Drew Gronewold, a hydrologist with...
