Improving security is probably more likely than beating climate change.

Severe climate conditions have pushed Guatemalans off their lands. Not enough rain. Too much rain. Crops destroyed and a government incapable of providing any solutions. From National Geographic:

Today, towards the end of yet another “rainy season” that brought no rain, many rural communities seem trapped in a dizzying vortex of catastrophe. Years of erratic weather, failed harvests, and a chronic lack of employment opportunities have slowly chipped away at the strategies Guatemalan families have used successfully to cope with one or two years of successive droughts and crop failures. But now, entire villages seem to be collapsing from the inside out as more and more communities become stranded, hours away from the nearest town, with no food, no work, and no way to seek help.

The fact that many Guatemalans are fleeing because of economic insecurity and not direct physical violence is not something to celebrate. Improving security is probably more likely than beating back the effects of climate change.
