This is the Hothouse Earth paper, which supposedly got media coverage last week that I completely missed despite scanning the media daily for articles on exactly this sort of topic. It argues that one or more tipping points leading to catastrophic feedback loops are looking increasingly likely if we exceed the 2 degrees C. So yes, we really need to get serious about not exceeding the 2 degrees C. But don’t worry, solutions exist! We need only take simple steps such as “decarbonization of the global economy, enhancement of biosphere carbon sinks, behavioral changes, technological innovations, new governance arrangements, and transformed social values.”
