Here’s a fairly typical migrant’s story. Like many of the world’s poorest people, you grow up on a small family farm. When an unusually long drought leaves the farmland barren, the family spends its savings to put you on a boat to Europe. You might drown in the Mediterranean without ever wondering whether you’re a climate migrant.
In fact, almost nobody on earth is strictly a “climate migrant”. Since every person’s decision to leave home is typically driven by a number of factors, it’s more accurate to talk about “climate-encouraged migration”.
Drought, for instance, was merely one of the causes of Syria’s civil war and the recent Central American “migrant caravan”. However, climate is influencing ever more individual moves.
