CFACT has a video of a speech made by physicist/astronaut Walter Cunningham while at COP 19 in Warsaw.
He starts by saying that climate used to be a very respected science, but that it began to deteriorate about 20 years ago and has long become politicized and is being misused for more government control. He believes that it has morphed into something that no longer resembles science and that skeptics are now being asked to disprove hypotheses.
Just after the 6-minute mark, Cunningham calls the hockey stick chart “phony” and that he hesitates calling those behind man-made global warming “scientists” because they have abandoned the principles of science.
He reminds the audience that new hypotheses must be supported by data, and that the global warming hypothesis fails the test.
At the 12-minute mark he comes right out and says “Their climate models have never successfully predicted anything” and that they are “based on assumptions, which are opinions.”
“Models are not data.”
At the 13:25 mark he adds, after searching for 15 years:
I have not found one piece of empirical evidence that man-made CO2 has a significant impact on global climate.”
Cunningham thinks that skeptics are winning the debate on the scientific front, but that the alarmists have the clear upper hand on the media front. “AGW is a matter of faith.”
He pleads with the audience to look at the data themselves and to make up their own minds. He says, “The IPCC is not a good place to look for objective data.”
He finishes with 4 conclusions:
1. There’s no reason to be concerned about today’s temperature or temperature trend.
2. Human produced CO2 is a miniscule factor in global temperature levels.
3. There’s no justification for believing CO2 and temperature are the ideal ones.
4. Humans cannot have any significant influence on the Earth’s temperature. Believing they can is a fantasy.
