Do some people not believe in global warming?

Answer 1

Some people don't believe, true.

A recent survey asked 3146 earth scientists, "Do you think human activity is a significant contributing factor in changing mean global temperatures?" (Doran 2009).

Overall, 82% of the scientists answered yes. However, what are most interesting are responses compared to the level of expertise in climate science.

• Of scientists who were non-climatologists and didn't publish research, 77% answered yes.
• In contrast, 97.5% of climatologists who actively publish research on climate change answered yes.

The more they are involved in research and publishing, the more they agree that humans are significantly changing global temperatures!

The same survey compared these results with data from a 2008 Gallup poll, which found that 58% of the general public believed human activity is contributing to global warming.

The paper concludes:

"It seems that the debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes. The challenge, rather, appears to be how to effectively communicate this fact to policy makers and to a public that continues to mistakenly perceive debate among scientists."

Answer 2

Below are the claims that they make. However, they have all been proved incorrect, out of context or cherry-picked. There is no evidence that global warming is not happening.

1. They point out that Vostok samples show that we have regular 100K year cycles they are the same, or warmer then we currently have.

2. That raw data from NASA shows the oceans are not warming. Algorithms have had to be added to make the data show warming. They question the validity of these algorithms.

3. They point out that CO2 has never caused warming or temperature change. It will always follow temperature changes by hundreds of years. The increase in CO2 levels that are claimed could be caused by the warming we have seen the past 11K years.

4. 1850 was the coolest portion of the last mini ice age. We would expect warming after the lowest temps in hundreds of year.

5. 90,000 plus measurements from the 1800's all showed the levels of CO2 in the atmosphere to be about what it is today. If you had put 330 ppm down as an answer for CO2 levels in college in 1850, they would have laughed at the low number.

6. Thousands of actual climate scientists disagree that man is the cause of the current warming trend. Many say we contribute.

7. Much of the data used to support man induced global warming has been found in error. The Mann hockey stick is not reproducible with actual data.

8. Items such as the claimed melting of the Himalayas are not actually occurring. No melting has been observed expect in one location. This melting is due to human tourism of the "melting glaciers".

9. The GISS refused to provide data to allow an audit. (Despite being publicly funded) When the figures were reverse engineered Doctor Hansen was found to have made "errors" that he has apologized for and admitted.

10. Ocean levels are not rising as predicted or in relation to the claimed warming.

11. The IPCC is made of less than 60 actual scientists. These are the primary promoters of AGW, not the actual science community

12. The proposed changes to help curb AGW provide no actual reduction in CO2 generation.

13. Nature produces 99.7% of all green house gases. Man produces 0.28% The ratios are too small to be significant.

14. The planet showed steady cooling during the largest increases in CO2 production. (1850 until 1934).

15. Every cooling period has started during higher levels of CO2.

16. Every warming period has started during low levels of CO2.

17. Milutin Milankovick predicted the current warming trend in 1917 using solar variation and planetary orbits. Vostok glacial samples show his numbers to be highly accurate and did not include CO2 measurements.

18. Thousands of scientists have a dissenting opinion similar to the 49 NASA scientists that complained last week (April 10, 2012) about NASA's lack of objectivity or the multiple signers of the petition project at OISM.

19. From 1934 until 19774 we saw steady cooling. This cooling occurred despite the steady increases in levels of CO2 emitted by man.

Answer 3

• Global warming skeptics (or sceptics)
• Global warming deniers.

Answer 4

they call those people non warmers
