Climate Change to have Marked Effects on Midwest According to New Report

ANN ARBOR—Climate change will lead to more frequent and more intense Midwest heat waves while degrading air and water quality and threatening public health. Intense rainstorms and floods will become more common, and existing risks to the Great Lakes will be exacerbated.

Those are some of the conclusions contained in the Midwest chapter of a draft report released last week by the federal government that assesses the key impacts of climate change on every region in the country and analyzes its likely effects on human health, water, energy, transportation, agriculture, forests, ecosystems and biodiversity.

Three University of Michigan researchers were lead convening authors of chapters in the 1,100-plus-page National Climate Assessment, which was written by a team of more than 240 scientists.

In the Midwest, extreme rainfall events and floods have become more common over the last century, and those trends are expected to continue, causing erosion, declining water quality and negative impacts on transportation, agriculture, human health and infrastructure, according to the report.

Climate change will likely worsen a host of existing problems in the Great Lakes, including changes in the range and distribution of important commercial and recreational fish species, increases in invasive species, declining beach health, and more frequent harmful algae blooms. However, declines in ice cover on the Great Lakes may lengthen the commercial shipping season.

The draft National Climate Assessment report is available at http://ncadac.globalchange.gov. A summary of associated technical input papers is available at www.glisa.umich.edu. Public comment on the draft report will be accepted through April 12.  The U of M news release is at http://www.ns.umich.edu/new/releases/21105-climate-change-to-profoundly-affect-the-midwest-new-report-says

ISEA and the Leelanau Conservancy will host a public seminar on climate change and invasive species on May 4, 3 pm at the Suttons Bay High School Auditorium.  More details on this event will be available soon.
