Unfortunately, politicians generally do not want to touch the climate crisis for the same reason that corporate leaders and other hucksters avoid mentioning it: It's bad for business.

We live in a world where the major premise of our money-driven Global Market Economy is that more is always better--growth is good, no matter what. However we live on a finite planet, a biological support system that is not getting any bigger, and whose carrying capacity we have already exceeded. To acknowledge that endless growth of production and consumption (and hence population and pollution) may be bad--not only bad, but catastrophic for all future generations--would be utter heresy. So don't expect politicians or the corporations that support them to even touch that (now inevitable) truth! We are on our own, I'm afraid.
