Ok, say we can cap global warming RIGHT NOW at +2c. This is it, all or nothing! What permanent percentage of your wealth and income are you willing to forego. Everyone else is in on it too. This is REAL PURCHASING POWER so no like "hurr durr if we all lose half our money, our money buys double" The other obvious big things will be solved as well, like plastic pollution, freeway pollution, they'll build a bunch of trains, mass switch to solar, we'll have new super blimps that fly low over the oceans so the container ships stop molesting the whales with their low frequency hums, the end to junk-mail, sustainable farming, THATS RIGHT WE SAVE THE WHALES, end the deforestation, you know all the good stuff.
