In 2015, 196 countries signed the Paris Agreement, a legally binding treaty with the goal of limiting global heating to 1.5°C above pre-industrial levels.

Since then, climate planning has increasingly revolved around overshooting this target, with the hope that temperature levels can be brought back down in later decades. Temperature overshoot models are now the default, but also a cause of scientific concern, as the devastating impacts of crossing this threshold may not be reversible. 

In their new book Overshoot: How the World Surrendered to Climate Breakdown, Andreas Malm and Wim Carton study this risky approach to policy, and the economic interests that they theorise have led to it. Alasdair spoke to them both about the new book.

Andreas Malm is Associate Professor of Human Ecology at Lund University, and the celebrated author of How to Blow Up a Pipeline, among other works. Wim Carton is Associate Professor of Sustainability Science at Lund University, and the author of over 20 academic articles and book chapters on climate politics.
