for two non-mitigation emission scenarios (sres a1fi and a

reference scenario close to sresa1b), both of which come close to, or exceed by a substantial margin, 4°c warming by 2100

Thats from the article itself.

If I'm understanding this correctly, then by non-mitigation they mean that in those models, no changes are made to our current GHG emission rate.

Which again, is simply not the case. Either way though, yeah a 4 degree world would screw stuff up for a lot of low latitude countries and hurt a lot of our biodiversity but we as a species would be fine.

GM foods can grow in poor soil conditions, desalination is becoming a real thing and carbon capture technologies are rapidly increasing... Add the 80-100 years or so before we reach the point where stuff will start to get bad and all the advancements that will be made in that time, and you can see why I'm not out there proclaimnig doom and gloom.
