Apparently your left column has no idea what your right column is doing. At the top left of page 15 in the Jan. 6 issue (“Y2K: One of the hottest, wettest yet”) you say Y2K is one of the hottest and wettest years yet. The first article starting on the right (“Sediments show bipolar melting cycle”) says that Earth’s sediments show regular periods of significant simultaneous icemelt. It goes on to say scientists think that this happened every 0.9 to 1 million years, and the last time was–guess what–0.9 million years ago. No doubt, we humans are adding greenhouse gases to the atmosphere at a tremendous rate, but maybe global warming is beyond our control, in the end. Gosta and Linda Johnson
