Well, if we look at the simpler question of whether we should do anything at all, even in the U.S. we have about two-thirds who think that the federal government isn't doing enough to reduce the effects of climate change [1]. Two thirds falls short of what I would consider "consensus", but it is a solid majority. In a well-functioning democracy one would think that should be enough, but unfortunately our democracy is not particularly well-functioning which means that the backing of two thirds of the public isn't enough to get legislation passed. To be fair, though, once you start talking specific proposals you'd get variable levels of public support. Cap and trade? Carbon tax? Biden's platform when running for president, if I remember correctly, was essentially all carrots and no sticks -- additional subsidies for EVs, federal funding for solar and wind, and so on. That's one way to get the public on board, though I personally think we ought to have a carbon tax too.
