*Another problem that global warming will create is that it'll make the hot regions of the world even HOTTER!

And as the hot regions of the world becomes hotter to the point where it becomes uninhabitable, mass migration then will overcrowd the habitable regions of the world which will surely become a big problem.

In addition, global warming alarmingly melts glaciers & the polar caps thereby hastening the rise in sea level that sooner or later, a lot of lands will become submerged underwater.

Coupled-up with uninhabitable hot regions, mankind then will really have a few land left to live in!
