why no abundant rain forests and melting caps?
Seriously?
Plants thrive in the temperature and humidity zone they are adapted to. Rain forests are drying out / succumbing to insects and dying off, amount of CO2 be damned. In western North America, we have bark beetles killing wide swaths of trees (the term “red and dead” was unheard of in the ’60s). Again, amount of CO2 not a factor other than the fact that the heat range has shifted upward.
No melting caps? Now you’re just messing with me…
Call it pollution if you want. Either way, crop losses are happening, insects are disappearing (how buggy has your windshield been since 2000?) and warming is directly observable by the lay person in their local area.
When the weather is nuts year after year after year, that’s climate change.
