In fact, the age group that least agreed with the statement that global warming is a fact and caused by CO2 emissions was that of 18 to 20-year-olds. The assumption that younger US adults are more liberal when it comes to global warming does not hold up; if anything, they are even more skeptical. --Emma Kromm, Harvard Political Review, 29 April 2015
According to the 1990 IPCC Report, an additional 0.5C global warming would need to be observed before natural variability could be distinguished with high confidence from an "enhanced greenhouse effect" due to man-made emissions. However, as an article today at Reason.com points out,
"...enhanced greenhouse warming above the noise of natural climate variability would not yet have crossed over the benchmark (+0.5°C) set by the IPCC back in 1990. Interesting."
Satellite data indicates only ~0.2C warming since 1990, considerably short of the 0.5C threshold the IPCC set for itself in 1990 to determine whether additional global warming was within natural variability.
Dyson: 'There certainly is an enormous religion in which there are lots of true believers who think that climate change is evil and that we're going to run into big catastrophes if we don't do something drastic. That's a sort of belief system which exists...I don't understand it and I don't pretend to understand their motives.'
Hansen accuses Tim Wirth of lying about stagecraft details: 'He just made these up later to make it seem interesting'
Wirth: 'Some myths about the hearing also have circulated over the years, including the idea that windows were left open or the air conditioning was not working. While I’ve heard that version of events in the past, and repeated it myself, I’ve since learned it didn’t happen.'
Tol says. '[The IPCC's] reputation of competence was shredded by the climate community’s celebration of the flawed works of Michael Mann'
'If you want to believe that climate researchers are incompetent, biased and secretive, Cook’s (97%) paper is an excellent case in point.'
The paper only claims that 97 percent of the scientific literature that takes a position on climate change (most does not) supports man-made global warming hypotheses. Yet supporters have used it to claim that 97 percent of scientists support global warming theories; they do not.
“In fact, about three-quarters of the papers counted as endorsements had nothing to say about the subject matter,” Tol says.
Cold snaps like the ones that hit the eastern United States in the past winters are not a consequence of climate change. Scientists at ETH Zurich and the California Institute of Technology have shown that global warming actually tends to reduce temperature variability.'
Former Sec. Stephen Chu: Excerpt: Chu praised China's ability to take unilateral action on climate change. "China doesn't have open elections, we do. That makes a big difference, for a number of reasons," Chu said. - "It's different in China because their government has to in the end look out for what's best for their country, for their entire people, not a particular industry," Chu added.
