Think Change episode 42: Rising tides, shifting borders - Migration in a changing climate

Written by Sara Pantuliano, Michai Robertson, Claire Kumar, Gaia Vince


Between 2008 and 2016, 21.5 million people a year were forcibly displaced from their homes by weather-related events, and the UNHCR predicts that globally, 1.2 billion people could be displaced by 2050 due to climate change.

This represents a hugely impactful but often overlooked consequence of climate change – one we are ill equipped to deal with.

With immigration expected to dominate the elections happening throughout 2024, today we are discussing how and why our changing climate is creating a new wave of migration and what this means for approaches to immigration policy and the rise of nativism.
