Climate Change Impacts on one of our Largest Lakes

May 19, 2010; 12:00 PM ET

The Nature Conservancy just released a climate change impact report on the Lake Champlain water basin. Lake Champlain is one of the largest lakes in North America. The Champlain watershed covers 8,234 sq. miles and encompasses northwestern Vermont along with parts of upstate New York and Quebec.

The Nature Conservancy report found the following........

--Mean air temperatures rose 2.1 degrees F (1.2 C) from 1976-2005. The most significant seasonal warming took place during the summer and fall. Data from eight USHCN weather stations in the watershed were used to determine this change.

--The ice cover season on the lake is now 2 weeks shorter than it was a century ago.

--The Lake Champlain water level is now one foot higher than it was prior to the 1970s.

--Total annual precipitation from 1976-2005 was 3 inches greater than it was the preceding 8 decades.
