People forget, migrations requires TWO things, someplace people can go (the US) and a place they have to leave (Southern Mexico and Central America). Why have these Hispanics being leaving? The low price of Corn since NAFTA was implemented (and before NAFTA do to the low price of corn, but this was made worse by NAFTA that ended Mexican Tariffs on US Corn going into Mexico). Now that corn is at record prices, the cities of Central America and Southern Mexico are hurting do to the high price of Corn, but the farmers themselves are seeing prices that are high enough not only to pay the bills but for extras.
People forget it was NOT the urban poor of Central America and Southern Mexico moving north, it was the Rural poor. This pool is now drying up. If the rural poor no longer want to go north, immigration will stop. Thus, in the short term, we will see higher wages as the Hispanics stay home and NOT underbid our own poor. Many Hispanics will move back, but many will stay, but we are going to return to the low immigration of the 1940s-1960s as far as net immigration (Through it will take a long time, maybe five years for people to stop coming).
On the other hand, where crops fail, you will see immigration, if such people can move. I do NOT see that in Central America or Southern Mexico (The Coasts are to near for any prolong drought and the affects on farming of Hurricanes only last for no more than a season). Europe will see a net influx from Africa do to the increase drought do to global warming. Northern Mexico has always been dry, but the population is richer then the rest of Mexico and thus have always been less likely to migrate to the US compared to Southern Mexico.
I read an article that pointed out our war in Afghanistan is destabilizing Pakistan do to people migrating from Afghanistan to Pakistan do to the war and the drought (Which I last read of last year, it may be over now, but hurting the wheat crop over at least the last two years).
Just a comment on migration patterns. People will move if they have no food, but if they have food and they can make money, even if low by US standards, they will stay. Thus the push behind Migration will decline (as far as the US goes).
One last comment, most people go to a new area based on information from people they know who is in that area. This has been known for hundreds of years. A study of German immigrants from the later 1800s was done. In that study is was found the number one reason that the German immigrants to the US relied on to move to the US was from relatives and Friends already in the US. This pattern exists for other groups, people go where family members already are OR here Friends are. Thus the movement was slow then it perked up as the price of Corn Dropped And more and more people went to the US, relying on friends and relatives already in the US to help them find and do work. Most immigrations can read and write, so letters are still used, but long distance phone calls are cheap today, and add to the distribution of information to friends and relatives. Generally the contacts tell the potential immigrants both the Good and bad points of where they are at. This helps prepare the immigrants for the transition. Thus migration patterns tend to bell like curves, Slow starts, then a "flood" then a drop till it is a trickle. People go, tel their friends and relatives, who tell other people. The flow peaks, and then drops as conditions back home improve (as it appears to be) and you have a reverse trend, people back home tells the immigrants that things have improve, and if things are NOT good in the new place, come back home. I suspect that is how the immigration pattern will go, a peak and then a slow decline.
