One Way Arguments

These are irrefutable truths to global warming skeptics:

If a climate scientist who supports the theory of anthropogenic climate change receives funding from an environmentalist group, the conclusions should be questioned because he has a financial interest in those conclusions. If a climate scientist who questions the theory of anthropogenic climate change receives funding from polluting industries, the financial contributions are merely an expression of confidence in the depth of his knowledge and quality of his analysis.

If temperature goes down, it is evidence that global warming is not occurring. If temperature goes up, it is due to natural "cycles" or some other such nonthreatening cause. It is not possible that nonanthropogenic causes put short-term downward and upward pressure on temperature, while anthropogenic causes contribute to the long-term overall warming trend.
