1. Pennsylvania will get hotter. Precipitation will increase with fewer but more violent storms and less snow cover. Expect adverse impacts on cool-weather crops, air quality, certain tree and wildlife species, including the state bird and fish.
And there will be a human impact, especially for those whose health is affected by heat or people who enjoy skiing, snowmobiling and ice fishing.
By midcentury, the number of days exceeding 90 degrees Fahrenheit will rise from an annual total of 10 to 40. The number of 100-plus degree days could jump from two to 24 in coming decades.
Those are some of the findings of the 2008 report, "Climate Change Impacts and Solutions for Pennsylvania," compiled by the Union of Concerned Scientists, with general agreement from the 2009 Pennsylvania Climate Impacts Assessment that Penn State University prepared for the state Department of Environmental Protection.
