Russian Arctic Methane Releases & Subsea Permafrost Degradation | Professor Örjan Gustafsson (Part 2)

ClimateGenn hosted by Nick Breeze

In this second episode of the methane miniseries, I speak to Professor Orjan Gustafsson from Stockholm University about his team's ongoing collaboration with the Russian research team, led by Professor Igor Semiletov, investigating the Siberian Arctic.

Orjan has published over 80 research papers jointly with his Russian colleagues on their findings in the Russian Arctic over the course of more than a decade. In this episode, he highlights why understanding this region is among one of the most important research areas in climate change today.

Despite the complexity of geopolitics that often infects peoples thinking in dealing with Russia, the opportunities for scientific collaboration in pursuit of critical knowledge can, in the long run, prove more beneficial than any short term political aims.
