In this episode of Shaping The Future, I am speaking with Glaciologist, Dr Heidi Sevestre, about the changing state of the Arctic, the outlook for the Russian Chairmanship of the Arctic Council, of which Heidi herself is an advisor, and how thawing permafrost could be past the threshold of irreversibility.

Heidi combines the spirit of the modern polar explorer with the weight of important scientific work. She is also an excellent communicator and will be speaking at the ChangeNow climate summit later this month in the company of Sir David Attenborough and world-renowned scientist, Johan Rockström, who will be premiering their new documentary, Breaking Boundaries, as part of the virtual summit.

Heidi also gives her perspective on why we literally must fight hard to limit global average warming to 1.5ºC, giving a rare insight into how someone who wanted to be a glaciologist from a very young age actually feels about the rate of loss of the world's glaciers.
