Finally, some good news on the climate. Good, but hesitantly good, mind you. British scientists working in a remote area of the tropical Atlantic have discovered that ozone levels there were 50 percent lower than expected. The reason for the discrepancy is due to a process in which UV rays from the sun are the catalyst for a series of chemical reactions which end with the breakdown of ozone and methane.

Yes, the Intergovernmental Panel on Climate Change has said that man is at the root of most of Earth's warming in the last five decades. Still, some researchers say the trend can be attributed to natural causes, including changes in the flux of cosmic rays slamming into our atmosphere, but now, according to Physics World, a pair of U.K. particle physicists have dismissed that idea.

Sallie Baliunas, an astrophysicist at the Harvard Smithsonian Center for Astrophysics, is pointing to a slide called Interdecadal Magnetic Variability Berillium 10. Its supposed to communicate something about the relationship between the suns intensity and climate change. All I see is a collection of squiggly lines. It could be an EKG or a seismograph test. The man sitting next to me appears to be equally lost. Hes snoring. The woman next to him is staring at her shoelaces.
