Seems like "scientists are basing their data on the past 100 years of air temperature.

The earth's atmosphere has been here for millions of years. Would it not make scence to base the data one the past several 1000 years of data,, a typical scientific way to run a test with more data points.

Obviously we don't have that data,seems like the pro global warmers don't care to explain that to the sientifically retarded

I'm looking forward to warmer winters in the northeast, spray that deoderant!
