Posted on June 2, 2019 by ...and Then There's Physics

A few people were sharing, on Twitter, a Science article called Promises and Perils of the Paris Agreement. It mostly seemed unobjectionable. It discusses the linear relationship between warming and emissions, and how this allows one to define carbon budgets … Continue reading →

There’s a recent paper on carbon cycle uncertainties and the Paris agreement (Holden et al. 2018). It considers two mitigation pathways, one that keeps end of century warming to below ~2oC, and the other that keeps end of century warming … Continue reading →

Pragmatism

Posted on December 14, 2015 by ...and Then There's Physics
