What are the positions of climate skeptics, sometimes called science deniers?

In 2018,  over 500 scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. Link

The belief in human-caused warming exceeding a level that what would be relatively benign, and maybe even beneficial, is just that — a belief. It is not based upon known, established, and quantified scientific principles. It is based upon the assumption that natural climate change does not exist.

Second, while we should try our best to take care of our planet, global warming is not the only urgent planetary emergency. Overpopulation, poverty, infectious diseases and the effect of globalization in spreading them, the water crisis, energy and food availability and safety, political instability and terrorism, the global economy, even cyber security, are far more urgent problems with potentially catastrophic results for humanity.

Science is all about proving, not believing.

Science would have never advanced if it were not for the skeptics.

Human activity, the oceans, extraterrestrial forces (solar activity and cosmic rays) and other factors are all in the mix.

Studies show clouds contol the climate link

 Outstanding article, it is all here, why climate science is not settled link

1Weather 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.

2 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.

3 There is tremendous uncertainty as to how the climate really works. Climate models are not yet skillful; predictions are unresolved.

4 New research shows fluctuations in energy from the sun correlate very strongly with changes in earth’s temperature, better than CO2 levels.

5 CO2 has very little to do with it. All the decarbonization we can do isn’t going to change the climate much.

6 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.

7 Sea level will probably continue to rise — not quickly, and not much. Researchers have found no link between CO2 and sea level.

8 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*.

9 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.

10 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*.
