'Natural internal variability due to heat exchanges between the ocean and the surface' account for the apparent slowdown since 2000, said Richard Lindzen, a prof.emeritus at MIT. He said the IPCC exaggerated the risks...Lindzen stuck to his past estimates that a doubling of CO2 concentrations would mean a rise in temps of only about 0.7 degree Celsius (1.3 F)'
