By funding its own research, industry has raised unwarranted doubts about a range of scientific issues — from the risks of tobacco to the reality of climate change — delaying response to public dangers for decades. Can scientists and journalists learn to beat the doubt industry before our most serious problems beat us all?

As Americans argue about how to tackle the issue of climate change, the astonishingly rapid industrialization of China is threatening to negate whatever progress we might achieve in reducing greenhouse gases. According to a new analysis by economists at two University of California campuses, China's carbon dioxide emissions are growing at a far faster pace than previously estimated -- and earlier estimates were worrying.
