Again, the argument is never that we won’t be able to survive as a species. The argument is that the climate change will greatly disrupt the current status quo, changing large parts of coastal parts into sea, displacing many people. Then current food production will get disrupted causing further displacement. The species will most likely survive. Whether is on the same advanced level and whether we will be able to make progress still, that is another matter altogether.
