80 years seems like too short of a timespan for this to meaningful, no?

I think it’s long enough, there are lots of atmospheric science papers finding significant trends over such timeframes (or even shorter). There is the question of interdecadal variability and whether we’re just seeing certain long-term cycles…but I’d think 80 years would be enough to even avoid many of those.

Good question. What do all of you think?

Not a great deal more data than that available in most places here in the U.S. What about Europe?

The 1910s and 1930s were some of the hottest on record, so I wonder how having those decades on the chart would change the perception.

It's long enough. Without warming, those fitted lines would be nearly flat. A month added to the growing season is very significant.

The year is 2700. Frost has become non existent.. Man makes electromagnetic earth pole diverters to tilt planet at correct angles to form seasonal changes.
