The climate science denying group the Global Warming Policy Foundation has admitted that it shared an “erroneous” temperature dataset to support Lord Lawson’s false claims to the BBC last week that global temperatures aren’t rising.
Three days after Lawson’s BBC interview – which was immediately and widely criticised in the media and by scientists – the climate denial group tweeted out Sunday afternoon that it was “happy to correct the record” and has since removed the tweet after a request to do so by climate scientist Ed Hawkins.
According to the tweets, the graph was originally produced by US meteorologist Ryan Maue, an adjunct scholar of the libertarian think tank the Cato Institute co-founded by Charles Koch. It was published by weather forecaster and climate science denier Joe Bastardi. Both Bastardi and Maue work for WeatherBELL Analytics, a private weather consulting firm.
