The trouble with many skeptics is that unlike real skeptics, they’ve never bothered to require that the people telling them things verify these things by some kind of test. If they say that it’s a warming from the sun, do they go out and ask whether solar irradiance can explain the warming, whether it’s even going in the same direction? No. Do they bother to learn enough of the science to figure out whether winter storms and polar vortices might have an explanation consistent with warming? No. When they talk about natural variability versus artificial, do they even realize that no climate scientist worth their salt is claiming that the natural version has just stopped? Skepticism requires that you be willing to drop a view when evidence or logical tests weigh in against it. It requires that you not take things at face value, but look at the data for yourself. By this standard, most Climate Skeptics aren’t skeptics, just pretentious dogmatists.
