Climate change is making the lives of many more difficult. Tens of millions of people are already displaced by weather events each year, and studies show that climate breakdown drives mental and physical health crises, increased conflict, drought, and food insecurity, among many other challenges. 

So why do leading climate models primarily measure impacts on Gross Domestic Product (GDP) rather than human wellbeing?

Inge Schrijver joins Alasdair on the podcast to discuss her new research into this question, and to explain how climate models work, how they are used, and what they are missing. 

Inge Schrijver is a PhD researcher at the Institute of Environmental Sciences at Leiden University. Her study, “Inclusion of wellbeing impacts of climate change: a review of literature and integrated environment–society–economy models,” was co-authored with René Kleijn, Paul Behrens and Rutger Hoekstra, and is available to read here.
