The Importance of Taking Action Now

The Thwaites Glacier in Antarctica is one of many bodies of ice that are melting, but this massive glacier is uniquely important when it comes to sea level rise. In this episode we talk to three experts studying the glacier in Antarctica to find out what's happening and why it's so significant.

Featuring Yixi Zheng, a PhD candidate in Oceanography at the University of East Anglia in the UK, Ted Scambos, a senior research scientist at the University of Colorado Boulder and Paul Holland, an ocean and ice scientist at the British Antarctic Survey.
