The scientific method goes: observation, hypothesis, testing -> theory. Over time, with significant testing and no counter examples, theory becomes accepted fact.
We can observe a small rise in average temperatures over the last couple hundred years. The earth has warmed a bit - on the order of a few degrees, 2 or 3 if I recall correctly. Even this is debated on a number of points that seem reasonable, but even if accurate the warming is not as dire as a casual observer would expect from all the alarmists running about. One would think the earth had warmed 10 degrees in the last 5 years from listening to the media.
What is really debateable is the cause. The ASSUMPTION that CO2 and other gasses are the cause has not been sufficiently tested. Indeed, the attempt to find a cause can ruin's one career.
So why all the pressure to not test the hypothesis that 'greenhouse gases' are the cause?
