As extreme weather forces people from their homes, the journalist and author Gaia Vince makes the positive case for immigration.

Projections show that billions of people will be displaced by 2050 due to the effects of global warming, a phenomenon she has reported on in her book ‘Nomad Century: How to Survive the Climate Upheaval’.

She argues that if governments plan for the mass movement of people they can reap the economic rewards of immigration despite public concern about the issue.

And with news that renewable energy overtook coal as the world's leading source of electricity in the first half of 2025, Gaia tells Amol why she thinks we’re approaching a “tipping point” which will see the end of our reliance on fossil fuels and green energy become the dominant source of power.
