#PeterSinclair: “Earth just hit 430 parts per million of atmospheric — the highest levels ever directly recorded.
When humans walked on the moon: 325 ppm
During 9/11: 369 ppm
COVID shutdown: 414 ppm
This week: 430 ppm
Last time it was this high, about 3 to 5 million years ago.
FYI sea level was 20 to 60 feet higher at that time.
Just sayin'.”
