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.
Year-to-year surface temperatures vary significantly. Look at a graph like this:
and it’s clear that we could easily have a string of years below this year’s temperature
We could but the current El Niño is supposed to be pretty significant. We also have significantly less sulfur oxide being spewed by international shipping which has a large cooling effect on the oceans. It is good that we cut down on that pollution and there are things we can replace it with that will have similar effects and are less damaging but there is currently nothing planned that would essentially replace that coming effect.
While you are correct that there is a good amount of variability in the temperature, I think it is just as likely that it will be variability the other way.
