I doubt the meteor, there would be a crater, unusual layers of dust etc.

What should be more and more apparent is that dramatic climate change occurs when there was no fossil fuel burning, and minimal agriculture.

However, the relentless rise in CO2 is spooking the heck out of would be rational scientists.

The fear is, intervention on CO2 might be the opposite of what is needed for optimum climate. But of course, there is a school of thought that the “proper” number of humans should be around a billion. Optimum climate may be an ice age for these folks.

What hubris!!

Isn’t Mars atmosphere full of CO2?.....and it’s pretty cold there......................

Not always, if it landed in the oceans. Some believe Hudson Bay is a meteor crater................
