A Climate Skeptic Converted

PBS Newshour ran an interesting segment Monday night on physicist Richard Muller, the scientist who made waves recently when he wrote an NY Times op-ed saying he now believes that humans are causing global warming. Here's the segment.

Muller says action must be taken on climate change very soon if we're to avoid the worst of its effects. From his op-ed:

What about the future? As carbon dioxide emissions increase, the temperature should continue to rise. I expect the rate of warming to proceed at a steady pace, about one and a half degrees over land in the next 50 years, less if the oceans are included. But if China continues its rapid economic growth (it has averaged 10 percent per year over the last 20 years) and its vast use of coal (it typically adds one new gigawatt per month), then that same warming could take place in less than 20 years.

UPDATE: Media Matters has an excellent look at NewsHour's segment, and how it "propagates confusion on climate change."
