Anyway, exactly what GM's brilliant idea to save the planet is I don't know, because I didn't bother to watch to the end; what I'm interested in is shamelessly repeating Timmy's argument, because GM's idea / analogy is all too common. It is, stripped down: during the 2008 banking crisis we urgently threw money at the problem; if we were to take Global Warming seriously we would urgently throw money at... something. This is an argument designed to appeal to greed and envy, and to trigger our sense of fairness3.
But as Timmy points out, the banking crisis was, errm, a banking crisis. The problem was money, and so the solution was money2. That isn't true of GW. You can, if you like, say that the problem is Capitalism1; but even so, the problem still isn't money. Indeed, as Timmy points out, one way to interpret GM's stuff is that his solution is less economy: we should all consume less. So the solution is... less money; well, no. The solution is directing our economy towards lower CO2 emissions, and doing so in an efficient fashion, because more efficiency means less CO24. Also known as carbon taxes.

1. FWIW, I don't think that is a good diagnosis, except to the extent that C has enabled us to grow so much richer that we're capable of causing problems like this.
2. Of course, that doesn't imply that what was done was optimal, or even correct; but that's another matter.
3. GM gets rather loathesome about this around 5:26. Why, he wonders, do pols not do what he wants? His speculation as to why is all you'd expect from him and his ilk: that the pols are corrupt and moneyed interests want otherwise. But whilst money is important, so are votes: if voters wanted their money spent by govts fixing GW, it would be done. But they don't. And they are aided and abetted in this by pols and the likes of GM.
5. Amusingly the URL has changed from h"how-the-number-25-can-save-the-world" to "the-tipping-point-that-will-destroy-the-world". I should probably also add that GM is rabbiting on about science that he doesn't understand and that is pretty dubious.
