Three readers - Chuck and Gail Kerfoot, and Jim Keat - have now told me they think it's gotten windier lately. "What is going on with that?" the Kerfoots asked. Robert Henson, at the National Center for Atmospheric Research, had no data. Winds are hard to summarize, he said. There is evidence high-altitude westerlies and jet streams are drifting north as the climate warms. That could affect surface winds below. But he said "there's certainly not a dramatic sign it's getting windier."
