Scholars’ Circle – Tipping points of Eco-Systems and Climate – October 1, 2017

We spent the hour looking at the science of tippings and what they mean for our climate and our ecosystems on land and in water today. What causes these types of sudden changes? And how can society be better prepared for such events? We spoke with three scientists whose studies involve tipping points, how they happen and their effects.[ dur: 58mins. ]
