Is climate change driving immigration to the United States from from Central America?

Please do not get me wrong.  I am not climate change denier.  But given the widespread reports of violence accompanied by the increased migration of women and children, I am not sure that Miranda Cady Hallett on this piece in The Conversation is correct that climate change is a significant contributor to emigration from Central America.  Her analysis  concludes as follows:

“In the absence of coordinated action on the part of the global community to mitigate ecological instability and recognize the plight of displaced people, there’s a risk of what some have called `climate apartheid.’ In this scenario – climate change combined with closed borders and few migration pathways – millions of people would be forced to choose between increasingly insecure livelihoods and the perils of unauthorized migration.”
