David Siegeldiscusses his current views on climate change and how he arrived at those conclusions. It is an excellent read, especially for someone that is open to scientific reasoning on why the science of climate change (or global warming) is simply not settled. In fact, if the science on global warming is settled, it would have to be concluded that man in the form of carbon dioxide production, has some but a slight influence on the climate.
Mr. Siegel claims that this paper supports ten statements. He then says that he will back those statements during the paper. Unfortunately, my reading is ineffective at substantiating his ninth statement. I tend to say that there is some pretty substantial evidence of destruction of reef systems by changes in the acidification of the ocean and there appears to be some linkage between acidification and levels of carbon dioxide.
Aside from his ninth claim, I think Mr. Siegel is very close to accurate on the remaining nine claims. They ten claims are:
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. The increase in storms is simply a result of improved measurement methods. There has been no real increase.
Natural variation in weather and climate is tremendous. Most of what people call “global warming” is natural, not man-made. The earth is warming, 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. They have more to do with hunting permits than CO2*.
No one has demonstrated any unnatural 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. Reefs are more threatened by sunscreen than by CO2.
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*.
