I'm not a Climate Denier, and I believe that Global Warming is due, at least in part, to human behavior. But I'd also point out that while we have ALTERNATIVES to fossil fuels, we do not have a SUBSTITUTE for fossil fuels, at least not as of now. And we're not on the brink of having a substitute, either. Green New Deals need to go forward with that reality.
But as I understand it, and I'll be the first to note that this plan is by their authors own admission still very much a work-in-progress, at the very least it seeks to phase out fossil fuels over a considerable period of time, not eliminate them entirely. Part of it includes tax breaks for electric cars Etc as having been discussed herein.
