I hope you don't have the notion that global warming means global drying. Warmer ocean temperatures increase rate of water evaporation, which in turn increases rainfall.

Some regions will probably become dryer (just as some regions will probably become colder), but I doubt you've have a rational basis for a belief that Central America in particular is likely to be one of the regions that will become dryer.

The Panama Canal is having problems now due to a prolonged drought. There have already been migrations from Guatemala and Honduras due to droughts in the highlands. Mexico City is facing a water problem partially due to drought.

From NASA: Increased evaporation will result in more frequent and intense storms, but will also contribute to drying over some land areas.

Don't know if Central America in particular will dry out in the long term. Was just using it as an example of the types of migrations that will come from global warming. Please try to understand the overall point and not pedantically nitpick.

Is your belief rationally based?
