Talk:Chris de Freitas
Email from CdF
Ive just recieved this email from the subject in answer to an enquiry about which ipcc reports he contributed to:
Reviewer’s efforts do not get credited as publications. Rather, their efforts are simply acknowledged. In my case see:
Page 558 of the SAR 1995, WG1
Page 851 of the TAR 2001, WG1
BTW, if you read what I write, you will see that I am not a global warming sceptic. I accept that rising human-caused CO2 from fossil sources could ‘change the climate’. The basic physics is there to support this view. But where is the evidence that the putative change would be large or damaging?
I have looked but I can find no unambiguous empirical evidence (not output from hypothetical models) that atmospheric carbon dioxide above preindustrial levels is a major driver of global climate, or that CO2 above preindustrial levels will be damaging or cause dangerous climate change. The so called ‘human fingerprints on climate change’ can also be attributed to causes or processes other than those related to fossil fuel-caused CO2 increase.
In the 1980s and 1990s I wrote papers warning of the threat of human-caused global warming from CO2 emissions, but had to stop when the data required to prove that view failed to materialise. Now there are several peer reviewed research papers that show negative feedback applies when radiative forcing is increased.
I accept one could reasonably argue that lack of evidence of ‘dangerous global warming’ ahead is not a good enough reason for complacency. But I believe the billions of dollars committed to global warming research and lobbying for global warming action and for Kyoto treaties etc. could be better spent on uncontroversial and very real environmental problems (such as air pollution, poor sanitation, provision of clean water and improved health services) that we know affect hundreds of millions of people.
