Today, people are three times more likely to be forced from their homes by climate-fuelled disasters than by conflict. In 2018, the UN estimated that by 2050 there could be between 25 million and 1 billion environmental migrants. In this video, I break down the climate refugee crisis, how international law is insufficient, and how complex emergencies will reshape the international world order.


I spoke on zoom with Oxford Professor Alexander Betts about how the UNHCR and the global refugee system can adapt to incorporate the realities of climate migrations and state fragility, which are currently two of the biggest drivers of displacement. We also discussed his book, Survival Migration, and the impacts of Covid-19 on the most vulnerable communities.
