I was invited to testify before the Senate environment committee September 26, on “The Impact of Global Warming on the Chesapeake Bay.” I told the committee there was no man-made global warming impact on the Bay. The Bay has been warmer than now several times because the moderate 1,500-year climate cycles have warmed it at least five times since the Bay was created 12,000 years ago. At least two of those cycles, and perhaps all of them, were warmer than today. Our net global warming since 1940 is 0.2 degrees C, with no warming at all since 1998. There’s no evidence that man-made CO2 has added much to this warming, though perhaps 0.1 degree C of today’s heat is due to the greenhouse gasses. The 1,500-year cycle is instead linked to the sun and the sunspot index. Nor has a single wild species gone extinct due to higher temperatures. Instead, the birds, butterflies , trees, fish and mammals have been extending their ranges, creating more biodiversity per acre than the world has seen in 500 years.

None of the Senators asked me about the cycle, the solar linkage or the wildlife. You never saw such an eager crowd of man-made warming enthusiasts. Chairperson Barbara Boxer of California waxed eloquent about her Committee’s recent trip to the Arctic, where she said the evidence of man-made warming was impossible to miss. She chided Republican James Inhofe because the extent of Arctic ice had just dropped to its lowest point since the 1930s. She failed to mention that this couldn’t be global warming--because the Antarctic ice has just hit a modern high. This is regional climate cycling, which the Polar Regions are known for.
