Green card holders only get limited social welfare benefits, and those illegally in the US get nearly nothing. It's a bit farfetched to believe that people embark on a 1500 mile walk through mostly desert country to the US border of which only half make it for only a 20% chance of getting into the US, legally or illegally. The driving forces In Guatemala leading to migration are crime, poverty and political corruption. Crime is the big issue for those living in Guatemala; statistically 84% to 87% of the violence is attributed to gang violence and drug trafficking. Parts of both Mexico and Honduras suffer from the same problem.It is true that the climate has always been changing. It might change a degree or so every thousand years. The problem with manmade climate change is that it is happening quickly. Too quickly. If you will look at the southern border of the U.S., you will see refugees from Central American. They are coming to the border because climate change has brought catastrophic crop failure to their region. Other regions are also affected, generally the more warmer regions, and the colder. Temperate areas, not so much.
You may be a little confused about this. They come to the US because we are a welfare state. We give them free stuff and they like it. Has nothing to do with the climate.
