TL;DR;

Capitalism was aware of the Y2K bug and took action even if it costs millions.

This is because my colleagues and my friends and I had been engaged in a multi-billion dollar, multi-year, multi-million person, quasi-coordinated project to fix the problem.

There are two obstacles to climate change to follow the same path though:

Responsibility for climate change is sparse and does not benefit an actor in particular if one makes some effort.

Capitalism's secondary tenet, short-termism, doesn't permit it to respond to non-specific risks, even if they're real, because that would require committing wealth to an effort from which 1-year or 5-year returns can't be measured in terms of greater wealth.
