(Boston, Mass.) -- Scientists have found the strongest evidence to date that human activity--burning fossil fuel and cutting down forests--causes global warming. Robert K. Kaufmann, associate professor of geography at Boston University, and David I. Stern, research fellow at Australian National University, uncovered the evidence using statistical analysis. Their full report, "Evidence for Human Influence on Climate from Hemisphere Temperature Relations," will appear in Nature on July 3.
