Interview: glaciologist Jason Roberts in Antarctica – video

Each day glaciologist Jason Roberts flies planes over Antarctica to map the terrain under the ice, trying to discover how climate change will affect sea level rise. Roberts, who works for the Australian Antarctic Division, says the point of his work is to look for the ‘canary in the coalmine’, identifying hotspots where warm water is interacting with the east Antarctic ice shelf, making it vulnerable to changing climate conditions that could have drastic implications
