Too bad the current rate of rise in average global temperature anomaly from the 1970 to 2020 is very significant, at 0.25 c per decade. The ocean temperature rise is no small matter either, as water has very large heat energy capacity, and measured heat total is accumulating at around 6 Hiroshima atoms a second. Accounting for this is a measured increase in greenhouse effect, attributed to greenhouse gases, which we overproduce. What other kind of smoking gun evidence did you want?
