Oops - IPCC AR5 Report Leak From Winger Denialist Blames Nonexistent Sunspots For Warming
EDIT
However, climate scientists pointed out that Mr Rawls has selectively quoted from the draft report and has ignored other parts of the document stating that solar activity and cosmic rays cannot explain the increase in global temperatures seen over the past half century, as sceptics have repeatedly claimed.
The AR5 draft report states that although there is “some evidence” that solar activity combined with cosmic rays may influence the formation of clouds, and therefore temperatures, but the phenomenon is “too weak” to influence the climate in any significant way.
The other major problem with the sunspots idea is that solar activity has largely flat-lined over the past 50 years, whereas average global temperatures have continued to rise, the IPCC report says. “The lack of trend in the cosmic ray intensity over the last 50 years provides another strong argument against the hypothesis of a major contribution of cosmic rays to on-going climate change,” the draft report says.
Professor Bill McGuire of University College London said that the IPCC report reiterates the widely accepted view among scientists that climate change is not a natural process but the consequence of human activities. “Alec Rawls’ interpretation of what IPCC5 says is quite simply wrong. In fact, while temperatures have been ramping up in recent decades, solar activity has been pretty subdued,” Professor McGuire said.
