      1979… Is the reading from the graph… I would guess that this is what the title refers to

          Even if it were the hottest 3 weeks in the last 44 years, it’s still the top 3 out of 2288 or so.

          However, it’s not the hottest 3 weeks (which would be an average of 7 days each). It’s the hottest 21 individual days. Each and every single one of them. The top 21 out of 16060 all happened consecutively, “now”. I don’t get how much more “dramatic” it needs to get before people like you understand what’s going on.

          You’re right, this chart is wrong and there is absolutely nothing to worry about. Ecosphere collapse amid the 6th mass extinction event in our geologic record is all a sham to sell…something?

      Roughly 500 years ago, maybe more. Recordings are spotty up to the 19th century. Monestaries often had a daily log of current weather, for example. There are likely recovered observations going back to Greek or Roman civilizations.

      Average temperatures can be deduced from scientific observations of ice cores and geological records as well. The arctic and antartic ice cores revealed detailed oxygen, carbon dioxide, and particulate data going back a couple million years.
