"global warming is a hoax."
Sure...
All you need is tens of thousands of scientists and weathermen 105 years ago to engage in a massive century long conspiracy spanning 100+ countries and to have this conspiracy continue til modern days.
Then you need modern scientists to fake new data from satellites, tree rings and glaciers and have all the governments of the world, including NASA and the Bush administration to be in on it.
1. Global warming: Real
2. Human Causation: Almost impossible but advocated by the Left
3. Kyoto treaty: pointless treaty to redistribute wealth advocated by the Left for political reasons
4. Conspiracy theories that global warming is not real: Response by well meaning people unable to distinguish between #1 and #2 and scared of #3.
