I will abandon the climate cult in all of its forms.

This is a framework that we’ve gotten totally wrong.

It’s what they call the anti-impact framework.

It treats carbon as the bad guy,

and says we have to measure it and decrease carbon emissions

at all costs.

That has shackled the American energy sector,

and that is the No. 1 obstacle to G.D.P. growth

in this country.
