I like webwalk's answer, but in any case, I'm not advocating skipping any necessary steps. We need all the necessary steps, just none of the unnecessary ones.
We need a revolution; this is not to satisfy me or keep the left happy or any such nonsense but so civilization and the human (and millions of other) species can survive.
Belief in a system can be extraordinarily resilient (stubborn or intransigent might be more fitting) but it can also collapse overnight once a tipping point is reached—just like an ice sheet or as James Hansen points out, shifting from Earth Climate 2.0 to 3.0.
The real problem is the US and secondarily other rich countries. The US corporate-owned government has actively sabotaged every effort to deal with the crisis and has still contributed more carbon pollution cumulatively than any other country including China. Most of the emissions in developing countries are the responsibility of the rich here and in those countries; they're caused by making products and growing food and cutting lumber for the rich. (the richest 7% of people cause half the GHGs; the poorest 80%—6 billion people—cause only about 20% of the GHGs. The emissions already emitted and in the pipeline (the ~40 year lag time between emission and full heating effect) are what are going to kill us if anything does, and those are overwhelmingly the fault of the rich countries.
China is forging ahead in front of most of the world with both solar and wind; it's exceeded its agreements to cut coal use. India has built and is building solar PV, solar thermal, and other renewables while trying to better the lives of many of the poorest people on Earth. A couple of dozen countries are at or near 100% of their grid from renewables; many are leapfrogging most of the fossil fuel age and jumping right into renewable age. None of this is fast enough, but the main and virtually only problem we have is the rich.
If you have trouble imagining, take a look at The Case for Mobilization linked to below, or do some other research on the US WWII mobilization. The US built many millions of tons of ships, planes, tanks, trucks, artillery, small arms, uniforms, supplies of all kinds; it supplied Britain with scores of ships and the USSR with trucks and other equipment. This country went from being a 2nd or 3rd rate power to being the most powerful country in the world, militarily and economically, and it did it in 3 years from almost a dead stop. The world has many times the industrial capacity that the US did then, we have the WWI and II experiences to learn from; the only thing stopping us is right wing denying delayalists and despairing negative people all along the spectrum. In the 2 wars there was an enemy trying to beat us (and with a damn good chance to do it). Now the only thing preventing our success is us.
