Just a theory
Tim Mannello writes another letter (Climate: Says who?) trying to convince the public that the science of man-made global warming is settled. If he wants to convince us our skepticism is unfounded he could simply answer the following questions:
What empirical evidence exists that we are in anything other than a normal climate warming cycle, that we are warming at a faster rate than any other time in the Earth’s history, that Co2 is the cause of global warming and not the result of global warming, and that man is the cause of global warming?
The truth to global warming science is, it is modeled around a theory.
