A heat wave that has stifled the southern tier of the U.S. for weeks has expanded into the Plains, Midwest and now the Mid-Atlantic and Northeast on Thursday, triggering heat alerts for over 227 million people, according to the National Weather Service.
Huh this is the first thing I’ve read that puts it into a sort of understandable perspective (eternally recovering from my conservative raised childhood, maybe sane people explain it better in general)
If you want a feeling for how your local temperatures will change you can extrapolate the peaks linearly. So if we look at London Uk as an Example https://ichef.bbci.co.uk/news/976/cpsprodpb/0394/production/_125961900_optimised-max_temp_uk-nc-002.png.webp
With a global mean temperature increase of 1 C since 1970 there was an increase in peak temperatures (avg) of about 2 C. So till 2050 it will be somewhere around 3 C for the average peak in summer. If we look at the ramp up since 2008 we can expect more like 5-6 C higher temperature records than today. So in the 2050s there will be some summers with 45 C records and the average hottest day every year around 35-37 C
Edit: and not to forget that this is only talking about how high the peaks every year are. The length of heatwaves will also increase by a few days. So where it was maybe 32 for three days and then 35 for one day, followed by a cooling thunderstorm it will be more like five days of 35 followed by a day of 37 and then a much more intense thunderstorm than what we know today.
