Hi @ed_hawkins, your #WarningStripes are awesome. I made my own version using the data from #BerkeleyEarth (and in 🇫🇷 ), but I changed the normalisation.
The way it is normalised is presenting #GlobalWarming to have started ~30 years ago which is not true. It also give the feeling that we changed from a cold period to a hot one, which isn't completely true. Before #climatechange, the temperature was fluctuating around a mean value, while now it is always much hotter.
