1. Concensus: This means nothing. In Galileo’s day everybody agreed that the sun revolved around the earth, but they were all wrong. The list of the concensus being wrong goes on forever.
2. Correlation does not mean causation: If you assume temperatures have risen at the same time that CO2 has risen this does not prove that CO2 causes GW.
3. Stance changes: In 70’s there the mantra was “global cooling”. This changed to “global warming” and now it is more of just plain old “climate change”.
It is pretty obvious that this is more than just a scientific belief. It is more of a sociopolitical belief, or even a religious belief. It is not cooling, warming, or change that people are worried about. These people are just need something to feel good about. They don’t care about evidence or proof because you don’t those things when you have faith. Look at all the wood burning stoves in Marin County for example.
Don’t get me wrong everybody. I don’t like pollution either, but I think the alarmist/unscientific attitude of environmentalism needs some change.
