Biden tried to do quite a lot better than the blue line initially, and Manchin unexpectedly blocked the first bill in the senate after it passed the house. They had to go back and redo a whole scaled-back version that was the actual blue-line-predicted version.
My overall feeling is, even the yellow line is nowhere near enough, but our current political class is bent on self-destruction because they don't actually grasp how bad it is (and will not, until it's even more too late than the too late it already is). But still, reducing it to the blue line is fuckin amazing within the current environment in Washington. The question should be "how do we get it lower than that now" as opposed to "how exhaustively can we shit on the guy who got the first round of changes done."
I firmly believe it is possible …. Or was. We may already be past the agreed limit to temperature rise trying to avoid the worst consequences.
If the target are the political ovens, like all electric personal vehicles by 2035 and net zero carbon by 2050, yes it can be done. It’s not, but it can be. We’re at a good state of technology now where we can get most of the way there just by rolling it out.
There’s no way the public would go along with or be able to afford replacing every single ICE vehicle in the country with an electric car in the next 10 years. As for industry, that would require a truly massive effort starting now to replace every gas or coal electric plant with nuclear, wind or solar… plus container ships and electrifying the entire domestic truck fleet, and also somehow bringing about an end to cattle flatulence.
