Is there a data source that says that temperature variances have increased? I have never seen meaningful evidence of this. > Same for other extreme weather events like hurricanes, wildfires, and droughts. Extreme weather events are extremely hard to define, and have such a low occurrence rate that you cannot extrapolate an increase in the timeframe we're discussing on a global level.
