I know things are getting warmer. Here in northern Illinois we recently had a tornado, but today we have had nothing but snow. For the past week the temperature has been around zero, which is colder than it should be if the globe is warming. Obviously the polar ice caps weren't always there, so maybe we are going through a warming cycle aided by human emmisions. We can't just believe Al Gore because it's Al Gore. Maybe in 100 years we'll be in an ice age. I hope not but it could happen.
