For fun I did 5-year running averages for each month's diurnal temp range here, not a long sample (periods 1999-03 thru 2016-20 so just an 18-year sample) and it revealed what I think are significant changes during that short period. The average yearly diurnal range has decreased by 1.8° over the period. One month, the low-range November (only DEC's is smaller) actually increased by 0.5° but the other 11 months all showed at least 1.0° decreased ranges, led by the 3.4° for October. My place was in the woods when we moved here in May 1998 and that has not changed. The increased atmospheric moisture appears to be buffering both extreme highs and extreme lows.
Raindancewx:
The tree ring sample caught my eye. I've been skeptical of the value of dendrochronology as analog for temp change, except at the cold-climate edge of a tree species' range. Having measured nearby trees' diameter growth at 2-week intervals for a number of years, I've found that spring temps can alter the commencement of growth (2020 and 2021 provided major contrasts) but the annual increment is affected far more by precipitation/soil moisture than by temperature - probably by an order of magnitude.
Edit: And I like eating meat too, but my favorite is deer meat and since I hunt on my woodlot with a rifle made in 1964, the GHG impact is minimal.
