I agree.
If the existence of life as we know it is at stake yet the possibility that people will change their behavior sufficiently does not exist, the only choices would seem to be saying goodbye to life as we know it or limiting consumption by limiting income. That might sound draconian, if not dystopian, but actually it would mean a far more just society--which could be accomplished by just means.
