L. David Roper, a retired physics professor in Virginia thinks so:
Media reports about the migration of children from Central America into the U.S. have blamed it on extreme violence in those countries due to drug gangs. The high use of illegal drugs in our country places most of the blame for the drug trade on some of us. However, there is a more insidious and basic blame that rests on all U.S. citizens which the main U.S. media almost never mention.
For many years countries of Central America have been experiencing extreme droughts and floods and consequent large declines in food production. Such extreme weather events are enhanced, and probably caused, by global warming. Honduras is ranked with Bangladesh as the two countries most susceptible to disasters caused by global warming; this year the Honduran rice crop was decimated by massive floods. The top three countries in the world that suffered the most from extreme weather over the last 20 years are Honduras, Myanmar and Nicaragua. El Salvador and Guatemala crop yields have been reduced by floods from violent storms. Guatemala and Nicaragua have had prolonged droughts.
For the last few decades the U.S. has been a major cause of global warming by burning fossil fuels, especially coal and oil. So, the root cause of the migration from north to south [sic] is global warming caused by burning fossil fuels in the U.S.
Is this premature?
