On climate change, Kerry and Gingrich agree (mostly)

In the debate between John Kerry and Newt Gingrich Tuesday about environmental issues, their similarities were more striking than their differences. It's time to accept the science as fact and act on global warming, for one. And incentives and tax cuts are part of the policy solution, they agreed, though Kerry would tack on some limits for greenhouse emissions. For Gingrich, the former House speaker and potential Republican presidential candidate, the debate was a chance to introduce his brand of "green conservatism." For Kerry, the last Democratic presidential nominee and a longtime environmental advocate, it was a chance to welcome him.
