This is a ‘get in there quick before everyone else does’ type post intended to promote further discussion over the coming days.
The Guardian has published an article today claiming that the planet is “at its hottest in 115,000 years thanks to climate change”. They base their alarming headline on a non peer reviewed ‘discussion’ paper released just this morning by Hansen et al, entitled ‘Young People’s Burden: Requirement of Negative CO2 Emissions’.
I haven’t read the paper yet but the general gist of it seems to be a ‘proof’ that it’s now as warm as the Eemian intergalcial 115,000 years ago – based on Marcott et al’s much criticised 2013 paleo temperature reconstruction – and that the only way we are going to avert a terrible climate catastrophe is to decarbonise the global economy as of yesterday and suck all the extra CO2 that we’ve already added out of the atmosphere. So, complete de-industrialisation and a massive geoengineering effort is required to stop the planet burning to a crisp via the system of ‘slow feedbacks’ (earth system feedbacks) that are inevitable if temperatures remain this high for much longer.
