We need to emphasize the message that massive amounts of infrastructure must be built both to limit and to adapt to climate change.
That's literally the opposite of damaging the economy. If we actually took climate change seriously as a challenge to civilization itself, we'd have a boom economy like it hasn't been seen in at least 50 years.
That is sort of the problem though. Climate change arguably wouldn't have been much of a challenge for western countries if we had continued to evolve our cities, infrastructure and applicable technologies. Instead our economies are mostly paper based so we can't make real world changes without affecting someone's contract, mortgage or stock value. Therefor we are left changing our papers around, which of course upsets anyone who need the improvements.
