Some Climate Scientists Are Not Being Honest With the Public — Here’s Why
I’ve seen articles claiming climate scientists are shocked at how rapidly the climate is manifesting extreme events that take lives and destroy property. When I read these I think Are they naive or mental? Are they actually climate scientists?
Here is why I’m so doubtful about any climate scientists claims of surprise concerning how rapidly weather events are hammering away at our civilization.
Fifty six million years ago the formation of the North Atlantic by volcanic activity doubled atmospheric CO2 from 500 to 1000 ppm in a period of 25,000 years.
The most similar event to ours was many millions of years ago.
The Paleocene-Eocene Thermal Maximum (PETM) “…is the most rapid and extreme natural global warming event of the last 66 million years.” It gives us one of the closest analogs to our current situation.
The only event we know of that may have resulted in quicker CO2 levels was the Chicxulub asteroid that killed the dinosaurs approximately ten million years earlier. The rise in CO2 levels may have been similar to PETM, although no article pins that down. Frighteningly, several sources say it took 100,000 years for the atmosphere to return to previous CO2 levels after the Chicxulub event.
This means the 400 plus ppm CO2 we have now and the 700 ppm (and rising) by 2100 is not going away for a long, long time, perhaps a 100,000 years. Much longer than any civilization has lasted on Earth. Some scientists predict a worst case scenario of 2000 ppm by 2250.
We are producing CO2 sixty times faster than that last comparable event 56 million years ago.
But, more frightening than that, humanity will do this in approximately 400 years instead of 25,000. That is 60 times faster than the massive volcanic disruption that formed the North Atlantic and caused the Paleocene-Eocene Thermal Maximum that drove temperatures up 9 degrees Fahrenheit (5 degrees Centigrade) higher than they are now and seas 10 to 15 feet (3 to 5 meters)…
