From David Siegal, What I Learned about Climate Change: The Science is not Settled
- Weather is not climate. There are no studies showing a conclusive link between global warming and increased frequency or intensity of storms, droughts, floods, cold or heat waves.
- Natural variation in weather and climate is tremendous. Most of what people call “global warming” is natural, not man-made. The earth iswarming, but not quickly, not much, and not lately.
- There is tremendous uncertainty as to how the climate really works. Climate models are not yet skillful; predictions are unresolved.
- New research shows fluctuations in energy from the sun correlate very strongly with changes in earth’s temperature, better than CO2 levels.
- CO2 has very little to do with it. All the decarbonization we can do isn’t going to change the climate much.
- There is no such thing as “carbon pollution.” Carbon dioxide is coming out of your nose right now; it is not a poisonous gas. CO2 concentrations in previous eras have been many times higher than they are today.
- Sea level will probably continue to rise — not quickly, and not much. Researchers have found no link between CO2 and sea level.
- The Arctic experiences natural variation as well, with some years warmer earlier than others. Polar bear numbers are up, not down. Theyhave more to do with hunting permits than CO2*.
- No one has shown any damage to reef or marine systems. Additional man-made CO2 will not likely harm oceans, reef systems, or marine life. Fish are mostly threatened by people, who eat them.
- The Intergovernmental Panel on Climate Change and others are pursuing a political agenda and a PR campaign, not scientific inquiry. There’s a tremendous amount of trickery going on under the surface*.
