Even the increase in migration from Central America to the U.S. is driven by extreme weather and lapses in agricultural productivity.

Yes, and the two are interrelated. Scarcity breeds insecurity, insecurity breeds conflict, and conflict destroys physical and societal infrastructure of production that leads to further scarcity. It becomes a vicious cycle. And indeed I believe you are entirely correct that a long legacy of U.S. neocolonial interventionism has contributed to the instability.
