Some of the Great Lakes’ treasured national parks are showing ill effects of climate change that are likely to worsen in coming decades, from shoreline erosion to decline of certain wildlife and plant species, a former park system administrator said Wednesday.

Without changes in public policies and personal habits that pump greenhouse gases into the atmosphere, the parks could lose qualities that attract visitors and support unique ecosystems, Stephen Saunders, former deputy assistant secretary of the Interior Department, said a report released by two advocacy groups.

Gainesville “Human disruption of the climate is the greatest threat ever to America’s national parks,” Saunders said. “Threads are being pulled out of the tapestry of these parks and the parks are beginning to lose their luster.”

The Rocky Mountain Climate Organization and the Natural Resources Defense Council helped produce Saunders’ report, which focused on five parks or lakeshores in the region: Indiana Dunes in Indiana; Isle Royale, Sleeping Bear and Pictured Rocks in Michigan; and Apostle Islands in Wisconsin. Together, they drew more than 4 million visitors in 2010.

Using federal temperature data and previous scientific studies, Saunders and colleagues said climate change was at least partially responsible for a series of unfavorable developments in the parks, which can serve as early warning systems for the wider environment.  See more of this typical advocacy,don’t bother to check the facts jpournalism here.

A few months ago in testimony to congress we heard similar information from the University of Michigan:

In testimony before the House Energy and Power Subcommittee, University of Michigan’s Knute Nadelhoffer, professor of ecology and environmental biology, said “greenhouse gas emissions from fossil fuels are changing the region’s weather and ecosystem…temperatures have risen 4 degrees Fahrenheit in the northern part of the Great Lakes and 1 degree in the southern region over the past 50 years.”

Lets look at Michigan temperature trends in summer and annual below - even with urbanization, no trend or slight cooling.

Liars everyone. They never think anybody will ever check the facts. They know their friends in the media can be counted on to believe them. The media is implicated in most of the economic woes we have in this country by backing these government, enviro driven policies driven by greed or ideology.
