evidence: Lawson: For example, he said that, er, there had been a growing increase, which had been continuing, in the extreme weather events. There hasn’t been. All the experts say there haven’t been. Extreme weather events have always happened. They come and go. And some kinds of extreme weather events of a particular time increase, whereas others, like tropical storms, diminish… [...] The table below summarises all the evidence then available to the IPCC on weather extremes. It shows the range of confidence that increases have occurred (first column), the assessment of human activity has contributed to observed changes (second column) and the likelihood of further change in future (third and fourth columns). [...] 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.
