It seems like almost everyone who doubts anthropogenic global warming bases their doubt on historical evidence, "common sense", or both. This puzzles me, because the global climate is far too complex to simply understand with common sense.
Most of the scientists skeptical of AGW appear to be geologists. This is because geologists study the Earth's history, and conclude "The Earth has gone through climate changes before, and been hotter than it is now, so the current global warming is no big deal". Many laymen use this same reasoning. However, this historical argument ignores the recent data which cannot be explained by natural cycles, as previous climate change events can be.
So some people conclude that because the climate has changed before, humans are not warming it now. Others conclude that humans are too miniscule to be impacting something as large as the Earth's climate.
They not only ignore a vast amount of data, but the experts' conclusions, based on common sense.
