All good points. For me it was disappointing but not unexpected to see the astroturfed optimism "here's why 1.5 C isn't all that bad" press that greeted the IPCC report about 6 months ago get replaced with "here's where you can Masque of the Red Death climate change." People are going to have to relocate, ideally sooner rather than later, and there are places that are going to be better to relocate than others, but nowhere will be untouched and people who think that's going to be the case are dangerous.
