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.
It will obviously affect all of us to varying degrees. But we won’t all die. Quite a lot will die (a lot of old people and a lot of poor people, as is tradition), but we don’t get anywhere by making a Hollywood movie out of it. It’s serious enough on it’s own.
