Consider this.
Planet earth was formed 5,000,000,000 years ago.
Human records on climate is less than 500 years.
That is a heckuva extrapolation to conclude climate change is something new and man made.
Geologists universally agree we had ice age a few thousand years back. What caused the global warming to melt all those glaciers? Man was still burning twigs to stay warm. Did the cave man burn too many twigs to end the ice age. So laughable and so stupid to think that.
The time scales do seem too short to infer much more than “noise” in the variations we see now. And massive CO2 content in the air is nothing new to this globe.
