BBC News, July 2007: ‘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.

The past few decades have been characterized by a period of relatively high solar activity.However, the recent prolonged solar minimum and subsequent weak solar cycle 24 have led to suggestions that the grand solar maximum may be at an end

As a result of the decrease in solar irradiance, both experiments show widespread cooling with respect to CTRL-8.5 (Fig. 2). The relative annual global mean near-surface temperature change for the period 2050–2099 is a cooling of 0.13 and 0.12 °C for EXPT-A and EXPT-B, respectively.

If Mr Lockwood is not careful, he might end up joining David Viner in the Hall of Fame!
