Sun not to blame for climate change, says study
July 11th 2007 Changes in the sun's outputs can not be blamed for modern-day climate change, according to new research.
In the Royal Society's Journal, Proceedings, researchers suggest that while the sun may have been to blame for changes in the earth's climate in the past, it is not now.
"Over the past 20 years, all the trends in the Sun that could have had an influence on the Earth's climate have been in the opposite direction to that required to explain the observed rise in global mean temperatures," says the report.
The study was carried out by Mike Lockwood from the UK's Rutherford-Appleton Laboratory and Claus Freohlich from the World Radiation Center in Switzerland.
According to the BBC, Dr Lockwood initiated the study in response to the TV documentary - The Great Global Warming Swindle - which was aired earlier this year. The documentary featured the cosmic ray hypothesis but showed graphs that stopped in about 1980, "because things diverged after that," says Lockwood.
