Study: Sun's Changes to Blame for Part of Global Warming

Increased output from the Sun might be to blame for 10 to 30 percent of global warming that has been measured in the past 20 years, according to a new report.

Increased emissions of carbon dioxide and other heat-trapping gases still play a role, the scientists say.

But climate models of global warming should be corrected to better account for changes in solar activity, according to Nicola Scafetta and Bruce West of Duke University.

The findings were published online this week by the journal Geophysical Research Letters.

Scientists agree the planet is warming. Effects are evident in melting glaciers and reductions in the amount of frozen ground around the planet.

So these scientists think solar is part of the picture, others think it's all of the picture, and others think it's none of the picture. That's a far cry from the monolithic it's-the-CO2-stupid view you'll hear in the mainstream media.

UPDATE: Here's the study.
