L'effondrement de notre civilisation est-il possible ? Quarante spécialistes se penchent sur cette question, sous la direction d'@AilletLaurent, au micro de @bernardzekri et du #Novascope https://www.nova.fr/podcast/novascope/le-novascope-avec-laurent-aillet
Deep Adaptation opens up a necessary conversation about the breakdown of civilisation https://www.opendemocracy.net/en/oureconomy/deep-adaptation-opens-necessary-conversation-about-breakdown-civilisation/
Today a call from a senior #climatologist engaged in @ExtinctionR for more attention to wider fields of scholarship on communication, change & #collapse risk. Such as found in #transformativeadaptation, @collapsology & @deepadaptation

"The fact that we have been so stunningly unable to react to #climatechange may have to do with (how...) #climate scientists have falsely assumed the position of superior expertise..."

Our response to a recent essay at openDemocracy questionning the science background of the #DeepAdaptation movement and its drivers of engagement - #collapsology @GeorgeMonbiot https://www.opendemocracy.net/en/oureconomy/deep-adaptation-opens-necessary-conversation-about-breakdown-civilisation/
Many scientists critique #IPCC conservativism, at times in peer reviewed journals. Scientists who like IPCC can state reasons for their subjective view. Criticising individuals or movements to defend IPCC seems panicky
