In this episode, Kate Cook is joined by two guest experts both directly involved in securing greater protection of the marine environment from the impacts of climate change, Gareth Cunningham, the Director for Conservation Policy at the Marine Conservation Society and Dr. Sian Prior, Director of Shipping Policy for the Brussels-based organisation Seas at Risk. Together they discuss ocean acidification, sometimes labelled the ‘evil twin’ of climate change, as well as the, so far unsuccessful, attempts to secure a net zero framework for shipping emissions at the IMO and finally the scope for adopting blue carbon measures to support marine resilience.
