Report: Climate change would make Minn. swelter

A science group has released a report showing that Minnesota summers could become much hotter if global warming goes unchecked.

The Union of Concerned Scientists released the report ahead of an expected vote Friday on a climate bill in the U.S. House that aims to reduce greenhouse gas emissions.

The report says that by the end of the century, average summer temperatures in Minnesota would rise by up to 12 degrees.

In the Twin Cities, there would be nearly 70 days every summer with highs over 90 degrees and nearly 30 days of high temperatures exceeding 100 degrees.

The report also warns of heat stress to crops, more flash flooding and worse smog.
