It's not the sun wot done it?
BBC NEWS | UK | 'No sun link' to climate change
A new scientific study concludes that changes in the Sun's output cannot be causing modern-day climate change.
It shows that for the last 20 years, the Sun's output has declined, yet temperatures on Earth have risen.
It also shows that modern temperatures are not determined by the Sun's effect on cosmic rays, as has been claimed.
Writing in the Royal Society's journal Proceedings A, the researchers say cosmic rays may have affected climate in the past, but not the present.
"This should settle the debate," said Mike Lockwood from the UK's Rutherford-Appleton Laboratory, who carried out the new analysis together with Claus Froehlich from the World Radiation Center in Switzerland.
Dr Lockwood initiated the study partially in response to the TV documentary The Great Global Warming Swindle, broadcast on Britain's Channel Four earlier this year, which featured the cosmic ray hypothesis.
"All the graphs they showed stopped in about 1980, and I knew why, because things diverged after that," he told the BBC News website.
"You can't just ignore bits of data that you don't like," he said.
Strangely it seems very easy to find graphs on line which claim to show the continued influence of cosmic rays on climate - for example Cosmic Rays and Climate Change, though I'm sure they haven't ignored this data.
After much searching, as the BBC doesn't seem to believe in linking to the real research, here is their paper.
Fighting talk - and there seems to be counter arguments in place already, but I look forward to a detailed response.
