Reader Mike A. writes to point out that even shark attacks are being blamed on Global Warming. A spear fisherman (who may or may not drive an SUV) was killed when a great white shark was attracted to blood in the water from speared fish. Vic Cockcroft from South Africa's Center for Dolphin Studies blames Americans and their love of greenhouse gases.

"The incidents of shark presence seem to be much higher around the coasts (than they used to be) ... There is evidence that our waters are warming up because of climate change, but whether this is making them more productive or not we don't know," Cockcroft said.

Since great white sharks enjoy temperate water (not hot or cold) global warming will eventually drive them all away.
