This is nothing like tobacco and the amount of money spent on research to support AGW absolutely dwarfs the amount of money that the energy companies spends. Here's a simple question: for the ground based sensors used in a significant portion of land based temperature readings, what happens if you just simply forgot to mow the grass for a couple of weeks. Or, in general, just don't mow it short enough? Answer: you'll get readings 2-5F too high, especially at night. The biggest issue is that the land based sensor data we rely on is kind of junk and is constantly being tweaked and changed, and the satellite based data is only marginally better.
