Episode 19: Hothouse Earth

03.09.18 By

Societies, economies and ecosystems around the globe are at risk of being hit by unprecedented extreme weather events causing serious disruption, should the world’s rising greenhouse gas pollution levels exceed a climate change threshold, according to a new international report.

The Proceedings of the National Academy of Sciences (USA) report ‘Trajectories of the Earth System in the Anthropocene’, investigates the risk of reaching and exceeding a climate tipping point, sparking a chain reaction of feedbacks in the climate system that could skyrocket global average temperature to well beyond a 2°C rise within a century or two and eventually lead to sea-level rises of from 10 to 60 metres higher than what is seen today.

This Climate Council Podcast episode investigates these findings with Climate Councillor and report lead author, international climate scientist Professor Will Steffen.
