If you have no data, you are taking the statement that it is not occurring on blind faith, which is no more scientific than the junk science of the envirals.
As I said, the data on this site seems to support it, but they do not give enough explanation of the data collection methods and variables for me to judge its accuracy.
As I said, this is what THIS web site says. It is the National Oceanic and Amospheric Administration. Their mission is to collect weather and climate data.
The question about the data that I am raising is how reliable certain portions are, such as tree rings.
Obviously, you just want to shout that there is no global warming and end the discussion. You also want to bash Bush.
