Or they won't and it might take a long time for societies to recover from the costs that climate change is bringing. Societies having to spend more in dealing with effects from climate change have to spend less in other stuff that are investments, stuff like education, R&D, healthcare, transportation; to build dikes, pumping stations, purchasing ever increasing food products after crop failures, rebuilding cities destroyed by climatic events (or moving whole cities/population centres that aren't possible to be rebuilt nor protected), building border defences to stop millions of climate refugees from immigrating to dwindling inhabitable spaces. All of that will have massive costs that will make life much harder for future generations. We don't know what our children futures will be because as humanity we never been through a truly global catastrophe affecting every single corner of the planet at the same time, not even World Wars were any close to the potential destructive power that fucking up our climate is.
