Wrong website for saying this.

You'll be cancelled and flagged (and so will I). COULD NOT AGREE MORE!

I also want to see what happens after in 2020 the whole world has stopped. Let's how many degrees the temperature lowers even with most factories and economical activity gone for months.

Atmospheric CO2 sticks around for a long time. Cutting emissions slows warming, but doesn’t decrease temperatures.

You might be thinking of Methane which does break down reasonably quickly.
