How does the earth balance energy?

Anthony Watts doesn't seem to like this new paper about how energy moves around the Earth system and out to space (archived here). I don't know where EurekAlert got the headline from, which Anthony didn't like. "Long-term global warming not driven naturally - Study debunks argument that warming is driven by natural factors". The press release at Duke, the home of the researchers, is different and reads:

Long-Term Global Warming Requires External Drivers

Regardless of the headline, the body of the press release is clear, and the study is quite interesting. The paper was by Patrick T. Brown, Wenhong Li, Jonathan H. Jiang, and Hui Su. (The authors thanked Drew Shindell in among other acknowledgements.) What the scientists did was look at the obvious and explore it in detail.
