Of course, I only have anecdotal evidence, but I swear that Winters are shorter and Summers are longer and hotter than 50 years ago.
Do I think that human activity is responsible? Yep, but more importantly, I believe the climate scientists.
40s for the low. My tomatos/squash/cukes already have flowers on them. I don't think it will be a problem cause the soil won't have a chance to get real cold. In fact I'm kinda glad it's slowing the heat down. We were 84ing for two weeks the end of Feb.
Next week mid 70s for the highs/mid 60s for the lows.
We finally got rain this morning. .25 inch and my rain barrels are now full.
As far as anecdotal evidence. The ptbs are building way too many condos/apartments and roads that act as heat sinks instead of expanding green space to cool the surfaces down.
Been watching this for 45 years now. Good luck.
