Scholars’ Circle – What happened at COP26 in Glasgow ? – November 28, 2021

November 28, 2021 host

After world leaders met in Glasgow to mitigate the climate crisis, what exactly did they discuss? What was in the agreement and what does that mean for the future of the planet? We break down some of the specific agreements and the language used to confront the climate crisis. How does a promise to “phase down” the use of coal fall short of the required action to confront the crisis? What role should indigenous peoples, largely unrepresented at the meetings, play at administering these carbon reductions? [ dur: 58mins. ]

Then, on the Scholars’ Circle panel, many observers argue, that the economic forces are corrupting medical care and eroding the trust between patients and their doctors. The problems in health care delivery have wide implications related to how health care should function particularly when there are limited resources. We examine the ethics of medicine and healthcare, and the modern day issues that complicate them.[ dur: 37 mins. ]
