There's a persistent problem when it comes to addressing the climate crisis. Polls consistently show that people care about climate change and want to see more done about it, but they're not convinced that everyone else feels that way. Because we underestimate public support, we hesitate on climate action. Progress is slow and easily reversed. At its worst, politicians falsely conclude that climate policies are unpopular and that they could win votes by binning them - and nobody calls them to account on that because we think that's what most people actually want.
