Last I recall, the vogue solution to climate change was a carbon tax -- maybe it would be steadily rising, maybe there would be a public dividend, or something like that. And then --

James Hansen is still speaking out for a carbon fee & dividend system. In an interview with Yale 360 a few weeks ago, he said

The one thing, which is most important, is the assertion by the fossil fuel industry and the people who support them, that it would be expensive to solve the problem, is absolutely wrong. There have been economic studies that show if you add a gradually rising fee to fossil fuels, by collecting a fee on fossil fuel companies at the source, the domestic mine, or port of entry, and if you distribute the money to the public, an equal amount to all legal residents, it would actually spur the economy.
