How bad are "nasty consequences" and "the world burns"? Maybe it doesn't matter if those things happen.
Do you think running out of oil will go smoothly? We already can't stand still for 5 minutes without blowing someone up in a resource war and basically all of our resources are plentiful for now.
Rising sea levels decreasing usable land. Rising temperatures destroying key organisms in the food chain. Mass deforestation is destroying the very things that allow us to breathe.
How much climate change affects you is a function of your wealth and your country's wealth (cost of basic resources as well as required countermeasures are growing). Anyone who's been on the low side of one or both of those variables will tell you that it's already miserable. Imagine, if you even can, what being in a poor country will be like when all the oil is gone, food can't grow the usual way (you need either hydroponics or serious genetic modification), increasingly unstable weather destroys everything you build and everyone else is out to get you to squeeze out every last drop of resources you might have?
What people with no such experience don't realize is that unlike our economic system, which funnels resources upwards, ecosystem collapse doesn't funnel them anywhere. It's just an endless pit and eventually, everyone is poor.
Example: Second world war. You might argue that it was not disaster comparable to climate change, but it did turn entire world upside down, disrupting everything aspect of life of vast majority of world's population. But it also led to incredible advancements in many areas, new discoveries in all sciences, new technologies, massive changes in societies as well.
So I don't see the situation as gloomy, we will survive, because we always do.
Taking an approach that "we will sort it out" ignores that the disaster is already unrolling, just too slow for most of us to notice. The longer we linger, the worse the situation, and the higher the human toll.
I look at the insanity in how the US responds to small movements of people now and despair at the thought of how we’ll deal with simultaneous waves of millions of climate refugees alongside the predictable handful of domestic crises.
