Summary

At the meeting, climate scientists gave colleagues a peek at where climate science stands 5 years after the last assessment report of the Intergovernmental Panel on Climate Change (IPCC). The climate models are bigger and more sophisticated than ever, speakers reported, but they are yielding the same wide range of possible warming and precipitation changes as they did 5 years ago. But when polled on other areas of concern, researchers say they see more trouble ahead than the previous IPCC assessment had, though less than some scientists had feared.
