It is this mechanism that maintains the habitability of the planet — and more greenhouse gases result
in incremental warming.

The video begins by accepting that CO2 acts as a greenhouse gas and that increased atmospheric concentrations can cause
some incremental warming, on the order of magnitude of 1C per doubling of concentrations.
