Climate change: do more now or risk catastrophe

Why are people still pretending that people will change their behaviors. It's time to just start planning for the worst case scenario or hope that we find a scientific breakthrough.

What this author forgets is that many young people today are not procreating because having children is increasingly becoming a luxury of the upper middle class. Why should childless individuals care all that much about how issues like global warming and growing economic inequality will affect future generations when they're desperately just trying to hold onto their current jobs in order to service increasingly unjustifiable levels of debt (home, medical, educational,...)?

Isn't it "do more now and deal with catastrophe"?

I dont know why I always click comments under political discussions on HN, but I always regret that

I see a lot of climate change articles that talk about what should be done, but none of them talk about why we should do anything. Considering that a vast portion of the population still doesn't believe it's a huge problem, they really should explain why climate change is a big problem. they don't give any details at all, only vague references to doomsday: "a catastrophic implications for the climate of this planet". How do they expect people to be convinced to do anything when no reasons or explanations are given.
