The SSP5 Full-based model say: "This world places increasing faith in competitive markets, innovation and participatory societies to produce rapid technological progress". In short, this is believing in a return of the "30 glorious" period with the utopia than a magic technology will solve everything in time. Then look for the example of Venice, with her sea level problem. Sure a very costly technology seem to have mitigated the high tides (for now). But in the same time, the "competitive market" of very big ferry-boats have replaced the high tides in the work of destroying the city. For the global sea level, there will be regions who will gain a lot of money with it, like northern Canada and maybe Russia, because, it will be more easy to excavate minerals/petroleum/gaz/etc. and transport them with new and economics sea routes. This will bring a lot of GDP globally, but in the same time, plenty of poor and populous regions will disappear. The lost in GDP will be small because they will go from poor to still poor (or dead). This... only if the Gulf-Stream did not change his route because of the climate change. This sort of very bad hypothesis is never accounted by this family of economic models. PS: The subject here is climate change, but the mass extinction of species is far more a problem then climate change because it cannot be reverted... until a few millions years.
