"Over the past decade, almost 22 million people have been displaced every year by weather-related events. The projection is even more staggering. By 2050, the forecast is that 1.2 billion people will join the ranks of climate migrants, most of them from the countries with the lowest capacity to deal with the fallout from global heating. They will not all be fleeing a fire or a flood. The climate crisis is not about a single photogenic weather event. The climate crisis is war, it is poverty, it is radicalisation, it is the disappearance of the habitat families have lived in for generations, and it is the geopolitical and security fallout of collapsing ways of making a living. The result is a movement crudely summed up as a "refugee crisis" – a description that makes a constant churn of displacement sound like an exotic temporary phenomenon that will abate, or can be quarantined to other countries, if only the barriers are raised high enough."
