Ever heard about Milton Friedman, the top liberal economist enumerated in one row with Rand, Mises, Hayek?
Well this is him advocating for carbon tax in 1979.
The problem was not really with Friedman or Hayek, who applied liberal economics to social challenges in quite a pragmatic way (it was Rand and Mises who were indeed dogmatic), it's a problem with today's left and right who never read neither Friedman, nor Marx, and know both from summaries written by demagogues similar to themselves.
@kravietz it’s going to need more than a carbon tax at this point: there’s no problem with the left if you’re talking about going beyond Marx, Class and Economics and markets - they’re limited and insufficient: libertarian municipalism as proposed by Bookchin is worth reading about as this seems like a solid alternative.

The very concept of economic "externality" mentioned by Cicala is fundamental to modern ecology, and base to modern environmental policies.
