Common Sense Questions On Global Warming

My disbelief of the idea that humans are causing global warming rests upon a temperature baseline.

I want to know what is the range of global temperatures that is considered "normal"?

I want to know how the range of global temperatures that are measured, today, can be compared to the ranges of temperatures measured in years past when we have more temperature sensors and the sensors are more accurate.

I want to know why the number of years chosen for the temperature sample that was chosen as a baseline, is long enough when we know there have been wide temperature ranges over the hundreds of years. Now, comes some common sense:

"I have no doubt that global - that a trend of global warming exists," NASA Administrator Michael Griffin said in a taped interview that aired Thursday on National Public Radio. "I am not sure that it is fair to say that is a problem we must wrestle with."

"I guess I would ask which human beings, where and when, are to be accorded the privilege of deciding that this particular climate that we have right here today, right now, is the best climate for all other human beings. I think that's a rather arrogant position for people to take," Griffin said.

Michael Griffin is right. He's toast.
