Every now and then I like to take time off from picking fights with Cato (unjustified) or Gene (always appropriate), and argue with people who say things like:
Why should we turn to economists for this? They are the ones who have been discounting environmental damage for well over a century. The paradigm of eternal growth is outright insane, and the dismissal of society-wide negative impacts has been disastrous time and time again. Any attempt to assess the “economics” of climate change should be scientific. It should not be the god-awful pseudoscience that has helped bring us to the climate problems we have today.
