Can’t find it. The title was along the lines of global warming might result in a net increase in usable land.

How is "land which is too cold to use now might be useable on a warmer world" and "human beings aren't as tolerant to higher heat as we once thought" the 'exact opposite' of each other?

Well, it might!

It might also be necessary for many people to migrate to cooler areas than where they currently live.

While I suspect this is probably not true, it is plausible due to the fact that there is a lot of land in the northernmost regions of the world.
