damn_registrars writes "Scientists from Edinburgh, Scotland have recently published a study based on data from 1,000 years of climate data. They have compared the effects of differing factors including volcanic activity, solar activity, and greenhouse gases to find which has the most profound effect on climate. They have concluded that the driving factor since 1900 has been greenhouse gases. Their work has been published today in Nature Geoscience: http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo2040.html"
