maybe willing to listen to all sides of the issues of Global Warming. some try and scare the daylights out of us and blame every hurricance, and huge weather events on Global warming. hard to call for me. last year in Michigan, we had a mild winter, warmer weather little snow and an early spring. this year our winter has been  brutal way more snow than average, colder weather and have no idea of when we will get spring weather. one year is one way this one different. who is to say which theory to believe?
