@curren Sorry to interrupt your optimism, but the reefs are boiling because of what happened twenty to thirty years ago. The damage we do today won't really become visible to laypeople before 2050. It is already far worse than we think it is because most people understand the slow speed at which everything actually moves. We may have crossed quite a lot of tipping points already; we won't be able to tell if a system has been tipped over or not until years to decades after the tipping point. And those tipping points aren't even fixed values -- many systems aren't only under stress from global warming or acidification, but also from unsustainable industrial resource extraction, from toxic chemicals, etc., and while we might be able to adequately model tipping behaviour in relation to one stressor and determine what the tipping point for a system in which too much CO2 in the atmosphere and/or too high temperatures is the only crisis, we can't even begin to model the polycrisis. We don't even know what our current level of commercial industrial activities does to the planet, and I don't even know if I will live long enough to see it all since I'm already 50, and I don't know whether I will make it to 75, most people in my family didn't live that long.
Even if we had a successful Eco-Socialist World Revolution tomorrow, things would still get worse for decades to come, but the longer the current type of global economy continues, the more likely the Sixth Extinction is to wipe us hominids off the planet forever.
