People simply can’t/won’t hear it. Society is clinging to any doubt or contrary viewpoint (and oil companies and their paid shills provide plenty) because it is difficult to envision the delicate and finite nature of our situation. Triggered methane releases are currently ratcheting up the warming, you can’t refreeze the permafrost, it rapidly cooks the planet.
No one wants to believe it, but this is the end unless dramatic changes are made. Having children, at this juncture, with what we know, is profoundly selfish. And folks cannot accept this, let alone, the changes that must be made, systemically, for society to survive.
