What Biden has done is to cut the issuance of drilling leases to the minimum required by law, pass the Inflation Reduction Act, enact a regulation to force vehicle electrification, and similarly force fossil fuels out of most power plants.
What Biden has not done: stop issuing drilling permits or impose export restrictions on fossil fuels. The former has some serious limits because of how the courts treat the right to drill as a property right once you hold a drilling lease, and the latter is simply untested.
Of course. Climate change is happening, and will keep getting worse until all the biggest countries agree to do and actually go through with doing something substantial about it (or to fully isolate the economies of those that refuse). Nuclear war is just an idea.
We need most of the West and the upper classes of China to reduce their consumption of meat and animal products substantially.
