Climate change is not an existential threat because climate change is something which the human race has been subject to since forever. Sometimes the change was radical, sometimes subtle. Radical as in glaciation, subtle as in the "Little Ice Age" or the warmer periods which saw the flourishing of the Roman and Viking civilisations - which, incidentally, both declined once the climate turned cooler. Humans are adaptable animals and will make it through the effects of whatever turn the climate makes this time as well. Thinking otherwise is just silly doomsday prophetising.

This is, by the way, also why I am pro-nuclear. It is clear that there are better ways of generating electricity than burning fossil fuels (which lead to environmental pollution/destruction as well as often subsidising less savoury regimes (and companies)). I'm also for putting PV panels on top of roofs an other "unused" surfaces while I see "solar farms" as a waste of space unless established in deserts or similar areas.

I'd suggest to read [1] some [2] books [3] and think this whole "we're all going to die" thing over. Yes, die we will, all of us, but not for the reason or in the way many people seem to think.
