No single one of these is unfolding in isolation because they are potentially mutually reinforcing calamities on a global scale. … Continue reading On the survival of civilization – Earth Day 2020
The Breakthrough Institute has been busy. Their director of climate and energy has published a critique of the use of RCP8.5 as BAU.* While it is true that many papers misinterpret RCP8.5 as being the worst case scenario and that this is equivalent to BAU, the authors of the RCPs recently reminded the climate community that RCP8.5 assumed maximum burning of coal , which is not what is … Continue reading Misrepresentation of business-as-usual emissions: The red herring of RCP8.5
