Its director is Benny Peiser,[6] an expert on the social and economic aspects of physical exercise, and it is chaired by Terence Mordaunt, co-owner of the cargo handling business Bristol Port Company.

[8] GWPF states that it is "deeply concerned about the costs and other implications of many of the policies currently being advocated" to address climate change and that it aims to "bring reason, integrity and balance to a debate that has become seriously unbalanced, irrationally alarmist, and all too often depressingly intolerant".

The judge ruling on the latest FoI request, Alison McKenna, said that the GWPF was not sufficiently influential to merit forcing them to disclose the source of the £50,000 that was originally provided to establish the organisation.

[21] The GWPF's first act was to call for a high-level, independent inquiry into the hacked e-mails from the University of East Anglia's Climatic Research Unit.

GWPF Director Benny Peiser said that the organisation did not doubt the science and was not going to discuss it, but want an open, frank debate about what policies should be adopted.

[23] A spokesman for the Met Office, a government agency which works with the Climate Research Unit in providing global temperature information, dismissed this call.

"[24] David Aaronovitch noted the GWPF's launch in The Times, writing "Lord Lawson’s acceptance of the science turns out, on close scrutiny, to be considerably less than half-hearted.

People such as Lord Lawson are not sceptical, for if one major peer-reviewed piece of scientific research were ever to be published casting doubt on climate change theory, you just know they’d have it up in neon at Piccadilly Circus.

The Guardian article cast doubt on the idea that an upsurge in scepticism was underway, noting that "in (the US) Congress, even the most determined opponents of climate change legislation now frame their arguments in economic terms rather than on the science".

Hannah Devlin of The Times found an error for 2003 and noted that if the period from 2000 to 2009 had been chosen, then a rise in temperature would have been shown rather than a fall.

The GWPF blamed a "small error by our graphic designer" for the mistake which would now be changed, but said that starting the graph earlier would be equally arbitrary.

[36] In October 2023, it was reported in Computer Weekly that John Constable of the GWPF was a member of the "Covid Hunters", a group of Brexit lobbyists who conducted a secret two-year-long attack on the prestigious science journal Nature.
