Professor Gretta Pecl (University of Tasmania, Institute of Marine and Antarctic Studies, Centre for Marine Socioecology) provides insights on the topic of ‘Why does 1 or 2 degrees make so much difference for species?’. This footage was shot at live public forums for the Curious Climate Tasmania project held across Tasmania in August 2019 as part of Australian National Science Week. Curious Climate was initiated by a group of scientists & journalists that wanted to know what the Tasmanian public were curious about in terms of climate change. This series of presentations cover the most popular questions submitted by the Tasmanian public, in response to a call out for questions from ABC Radio, and aim to bridge the gap between experts and audiences with credible, relevant information about climate change.

Funding was provided by National Science Week and the Tasmanian Government, through the Tasmanian Climate Change Office.
