The Great Lakes may be drying up

2014-02-04 23:15:00| Climate Ark Climate Change & Global Warming Newsfeed

Grist: On Earth, cycles are the norm. Tides, carbon, water, life - they ebb and flow. Change, by itself, isn`t necessarily strange. What is strange is when cycles are broken. In other words, it`s not strange on its own that the level of the Great Lakes is dropping. It is strange that, when the lakes` levels normally change over a 13 year cycle, they`ve now been going down for 16 years straight. That`s 10 more than they should have been dropping for.

Great Lakes Water Levels Are in Unusual Decline

2014-02-03 16:08:00| Climate Ark Climate Change & Global Warming Newsfeed

LiveScience: The Great Lakes share a surprising connection with Wisconsin's small lakes and aquifers -- their water levels all rise and fall on a 13-year cycle, according to a new study. But that cycle is now mysteriously out of whack, researchers have found. "The last two decades have been kind of exceptional," said Carl Watras, a climate scientist with the Wisconsin Department of Natural Resources and the University of Wisconsin-Madison. Water levels have been declining since 1998, Watras told Live Science....

Arctic icy lakes lose thickness

2014-02-03 14:10:00| Climate Ark Climate Change & Global Warming Newsfeed

BBC: The ubiquitous shallow icy lakes that dominate Alaska's Arctic coastal plain have undergone a significant change in recent decades. These lakes, many of which are no more than 3m deep, melt earlier in the season and retain open water conditions for much longer. And 20 years of satellite radar also now show that far fewer will freeze right through to the bottom in winter. The results of the space-borne survey are published in The Cryosphere. What is happening to the lakes is an example...

10-Year Water-Cycle Trend Identified in Wisconsin Lakes

2014-01-25 14:31:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World: A 10-year water-level cycle has been identified in Wisconsin's lakes, and researchers there were surprised to find that even the smallest lakes followed the same trend as gigantic lakes like Michigan and Huron. "There was absolutely no reason for us to expect that our little lakes and lakes Michigan and Huron would act the same way, but they did," said Carl Watras, a research scientist with the Wisconsin Department of Natural Resources. Wataras was part of a team of researchers the documented...
