"Extreme Events Are the New Norm"

The UK's Meteorological Office, used 14 climate models and many runs, to determine the likely frequency of a European summer like that of 2021. In case you don't remember, the average temperature was 1 degree Centigrade higher than in recent times and the heatwave resulted in wildfires across the continent (https://www.theguardian.com/environment/2021/nov/03/europe-record-summer-global-heating-cop26). The Met Ofice analysis covered the whole continent, as far East as Yekaterinburg in Russia. It found that, in the 150 years prior to the 1990's, an extreme summer like that of 2021, would occur no more frequently than once in 10,000 years. Since 1990 (and the bulk of global heating), the expected frequency in the models rocketed to once every 3 years. Such summers are likely to become annual events. People at Cop26 are still talking about the need to limit global heating to 1.5 degrees Centigrade above pre-industrial levels! That increase admittedly starts from a lower baseline but the chances of achieving it, appear increasingly remote.
