Hotter-burning sun warming the planet - Washington Times: "'The sun has been at its strongest over the past 60 years and may now be affecting global temperatures,' said Sami Solanki, the director of the renowned Max Planck Institute for Solar System Research in Gottingen, Germany, who led the research.

'The sun is in a changed state. It is brighter than it was a few hundred years ago and this brightening started relatively recently -- in the last 100 to 150 years,' Mr. Solanski said."
