Why is Minnesota warming so fast?

On this week's Climate Cast with MPR News' Chief Meteorologist Paul Huttner, we'll discuss why Minnesota is number one on the list of the fastest warming states since 1970.

From Climate Central:

An analysis of data from the U.S. Historical Climatology Network of weather stations shows that the coldest states are warming the fastest, and across the country winter warming since 1970 has been more than four-and-a-half times faster per decade than over the past 100 years. Winter nights across the country have warmed about 30 percent faster than nights over the whole year. Some states cooled or failed to join the warming trend over the past 100 years, but since 1970, every state has shown winter-warming...

Since 1970, winters in the top 5 fastest-warming states -- Minnesota, North Dakota, Wisconsin, Vermont and South Dakota -- heated up four-and-a-half times faster than winters in the 5 slowest-warming states.
