Summary - This is an extremely important paper with a startling conclusion of the magnitude of the social and economic impacts of the biodiversity disruption coming down the pipeline - It is likely that very few governments are prepared to adapt to these levels of ecosystemic disruption - Climate departure is defined as an index of the year when: - The projected mean climate of a given location moves to a state that is - continuously outside the bounds of historical variability - Climate departure is projected to happen regardless of how aggressive our climate mitigation pathway - The business-as-usual (BAU) scenario in the study is RCP85 and leads to a global climate departure mean of 2047 (+/- 14 years s.d.) while - The more aggressive RCP45 scenario (which we are currently far from) leads to a global climate departure mean of 2069 (+/- 18 years s.d.) - So regardless of how aggressive we mitigate, we cannot avoid climate departure. - What consequences will this have on economies around the world? How will we adapt? - The world is not prepared for the vast ecosystem changes, which will reshape our entire economy all around the globe.

question - 2024 - Sept 13 - how do we reconcile climate departure with quantification of earth system boundary biodiversity safe and just limit? - Annotating the Sept 11, 2024 published Earth Commission paper in Lancet, the question arises: - How do we reconcile climate departure dates with the earth system boundary quantification of safe limits for biodiversity? - There, it is claimed that: - 50 to 60 % of intact nature is required<br /> - https://hyp.is/Mt8ocnIEEe-C0dNSJFTjyQ/www.thelancet.com/journals/lanplh/article/PIIS2542-5196(24)00042-1/fulltext - a minimum of 20 to 25% of human modified ecosystems is required - https://hyp.is/AKwa4nIHEe-U1oNQDdFqlA/www.thelancet.com/journals/lanplh/article/PIIS2542-5196(24)00042-1/fulltext - in order to mitigate major species extinction and social disruption crisis - And yet, Mora et al.'s research and subsequent climate departure map shows climate departure is likely to take place everywhere on the globe, with - aggressive RCP decarbonization pathway only delaying climate departure from - Business-As-Usual RCP pathway - by a few decades at most - And this was a 2011 result. 13 years later in 2024, I expect climate departure dates have likely gotten worse and moved closer to the present
