evidence: Lawson: No, it’s not happening. The reputable scientists, reputable experts, like Professor Pielke [Jr] and, as I’ve said, the IPCC, has confirmed that there has been no increase in extreme weather events. And as for the temperature itself, it is striking, he made his previous film 10 years ago, and according – again – to the official figures, during this past 10 years, if anything, mean global temperature, average world temperature, has slightly declined. A number of climate scientists have been quick to point out that Lawson is completely wrong to claim that the average global temperature has "slightly declined" since 2007. In stark contrast to Lawson’s claim, the global surface temperature over this period has risen, with the three hottest years on record occurring in 2014, 2015 and 2016. Lord Lawson argued on BBC that global temperatures have declined over past 10 years. Opposite is true, if anything warmed slightly faster. pic.twitter.com/k3nZumqYTH — Zeke Hausfather (@hausfath) August 10, 2017
