 In July 2008, the Conservative magazine "Standpoint" published a transcript of a double interview with Lawson and Tory Policy Chief Oliver Letwin, in which Lawson described Letwin's views on global warming as "pie in the sky" and called on him and the Tory frontbench to "get real".On 23 November 2009, Lawson became chairman of a new think tank, the Global Warming Policy Foundation, a registered education charity, involved in promoting climate change scepticism.In 2011, Bob Ward of the Grantham Research Institute said that the GWPF was "spreading errors" and "the 'facts'" Lawson "repeats are demonstrably inaccurate".
