Top 35 Denialist Claims

I may try to respond to each claim separately, using as many references as I can find. It will take some time to do a good job.

1. Warming is not happening.

2. Any warming in the instrumental record is suspect because of poor data.

3. Any increase in temperature is natural, and due to some unknown (solar) influence.

4. Most of any increase is due to urban heat islands, which have not been adequately corrected in the record.

5. Past warm periods prove that current warming is natural.

6. We are warming because we are coming out of the Little Ice Age.

7. The Medieval Warm Period was a global phenomenon and proves that today’s warming is entirely natural.

8. There is no such thing as a “Greenhouse” effect. Actual physicists have proven this experimentally.

9. CO2 is not a (major) cause of warming.

10. CO2 lags behind temperature in the Ice Core data by 800 years so it can’t cause warming.

11. Water vapour is more important than CO2 in warming.

12. CO2 is good for plants and humans, so burning fossil fuels is good for us.

13. There is no proof that the increase in CO2 is due to burning fossil fuels.

14. A warmer climate will be good for us.

15. The hockey stick is broken.

16. The IPCC’s whole case is based on the broken hockey stick and so it is wrong.

17. Scientists are biased because they rely on science funding bodies for their extravagant lifestyles.

18. Scientists have politicized science in order to keep the AGW theory alive.

19. AGW supporters want to send us back to the dark ages / communism.

20. They hate us for our freedoms, not for what we do. (oops, sorry, wrong denial)

21. Funding bodies only want to see research that supports global warming.

22. Scientists working on global warming are so friendly with each other they are unwilling to criticise their colleagues and point out errors in the papers.

23. Scientists will not challenge the extremists because they are afraid to lose funding.

24. Scientists are manipulating the temperature data in order to make it appear as if there is warming.

25. The models are flawed.

26. The uncertainties in the science are too large for any policy to be based on the data.

27. The predictions from models are wrong.

28. Global warming ended in 1998. In 2008.

29. The scientists in the 1970s all predicted a new ice age and they were wrong then. They are wrong now.

30. Peer review is broken.

31. The editors of journals will not publish articles with data that challenge the “consensus”.

32. There is no consensus.

33. The AGW hypothesis cannot explain the temperature decline during the 1950s – 1970s.

34. 100, 400, 18,000 PhDs, Scientists, Important People (any old person we could get) signed petitions stating that they do not support the theory of AGW.

35. Any old bonehead can do climate science and decide for themselves if global warming is happening.



  1. I’ve been fighting my own battles over global warming denialism. This is one result:
