Not really. At one point the horse-drawn carriage industry was probably pretty p#ssed about what Henry Ford was doing. Society moved forward anyway.
It's used now because all of modern science literally tells us that if we don't take steps to address climate change soon, we're literally going to damn ourselves to a horrible deadly future. We could spit in the face of all of modern science, but why risk it? As opposed to something like border control, where one party crafts their argument on the basis of feelings and beliefs. If we don't build a wall on the southern border, the earth isn't going to eventually succumb to natural disasters and doom our species to a fiery death. Immigration rates will just continue to fall.
Also, if you subscribe to the Overton window theory of politics in the U.S., it doesn't really matter if the leftists and environmentalists know what they're talking about. They're advocating for strongly pro-environment policy, which pushes the conversation in that direction, which IMO is sorely needed because one major party's solution to the problem is to literally ignore it because A) it's not real or B) it's too expensive (it's not - they just don't want to upset the Big Energy apple cart).
