The people (i.e. voters) overwhelmingly support action to limit climate change. That's the reason those laws are politically viable in the first place.
Once enacted, trying to undo them after being in place for 4 years will not only be difficult procedurally but politically suicidal.
It won't happen unless the political party in question has so much electoral buffer that they can ignore what 70%+ voters think about the subject.
Furthermore, if you believe that the climate is changing for the worse then every year will be even more devastating than the one before.
Power cables and roads in Oregon melting due to extreme heat? Next year even more cables and roads will melt.
Every year the public support for climate action will grow and opposition to it will become even more politically suicidal.
