Solar variations not behind global warming: study

The sun's changing energy levels are not to blame for recent global warming and, if anything, solar variations over the past 20 years should have had a cooling effect, scientists said on Wednesday.

[...]

There is little doubt that solar variability has influenced the Earth's climate in the past and may well have been a factor in the first half of the last century, but British and Swiss researchers said it could not explain recent warming.

"Over the past 20 years, all the trends in the sun that could have had an influence on Earth's climate have been in the opposite direction to that required to explain the observed rise in global mean temperatures," they wrote in the Proceedings of the Royal Society.


Now can we have a couple more studies to back this one up, please? Extra ammo is a Good Thing.
