The number of scientific "heretics" is growing with each passing year. The reason is a collection of stubborn scientific facts. Perhaps the most inconvenient fact is the lack of global warming for well over 10 years now. The lack of warming for more than a decade—indeed, the smaller-than-predicted warming over the 22 years since the U.N.'s Intergovernmental Panel on Climate Change (IPCC) began issuing projections—suggests that computer models have greatly exaggerated how much warming additional CO2 can cause. -- Claude Allegre +15, The Wall Street Journal, 27 January 2012
