There is a really silly paper in the Proceedings for the National Academy of Sciences, which claims that global warming will cause millions of Mexicans to migrate to the United States. As anybody with some basic knowledge about history knows, mass migrations always come before the warming, and not after it. The Völkerwanderung or Migration period where Goths, Vandals, Anglons, Saxons and Huns moved around over Europe came before the Medieval Warming Period (see map). The great migration from the Old to the New World happened before the Recovery from The Little Ice Age period. Hence global warming cannot cause migrations - it must be the other way around.
And if Mexican migrations really would become a threat, the easiest solution for the United States would be to adapt and build a wall. Or maybe invade Canada. That would make much more sense than to stop using fossil fuels, which wouldn't have any noticable effects on the climate anyhow.
Utinam barbari spatium proprium tuum invadant!
