Understanding The IPCC Climate Assessment

Richard Lindzen –
October 9, 2013

In this post at CATO @ Liberty, Richard Lindzen asserts that each IPCC report concludes that the case for an international agreement to curb carbon dioxide has grown stronger. With respect to climate, we have had 17 years without warming; all models show greater tropical warming than has been observed since 1978; and arctic sea ice is suddenly showing surprising growth. And yet, as the discrepancies between models and observations increase, the IPCC insists that its confidence in the model predictions is greater than ever.
