Show Summary
On this episode, Nate is joined by climate scientist and policy ambassador Sir David King to unpack the current situation regarding Earth’s climate system and human response (or lack thereof) to the accelerating heating of the atmosphere. While there are many uncertainties this field still grapples with, the fundamentals of the rising average global temperature as a response to increasing man-made greenhouse emissions are widely recognized by the global scientific community. Yet – especially in the United States – climate change remains a contentious issue, making it an even tougher political topic with no easy solutions. What is the basic science behind our understanding of the atmosphere? Will we resort to geoengineering to avert the worst climate outcomes – and which plans look the most promising? What are the implications of global heating for the coming decades and beyond?
About Sir. David King
Sir David King is an Emeritus Professor of Physical Chemistry at the University of Cambridge. He is the Chair of the Climate Crisis Advisory Group, Founder of the Centre for Climate Repair at Cambridge, and an Affiliate Partner of SYSTEMIQ Limited. He was the UK Government Chief Scientific Adviser from 2000-2007 and the Foreign Secretary’s Special Representative on Climate Change from 2013-2017. He also spearheaded a collaborative program called Mission Innovation, which involved 25 countries and the EU to create a publicly funded £23bn pa research and development international exercise aimed at delivering all technologies needed to complete the transition into a fossil-fuel-free world economy. He has been a Fellow of the Royal Society since 1991 and a Foreign Fellow of the American Academy of Arts and Sciences since 2002. Sir Dave was knighted in 2003 and made “Officier dans l’ordre national de la Légion d’Honneur” in 2009. Recently, he was also named The American Association for the Advancement of Science 2022 Hamburg Awardee for Science Diplomacy.
In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President
That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher
We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF
This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor
