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

Cities across the country will begin to reach “climate departure”: a symbolic rubicon, after which a climate falls completely outside historical norms.

- Cities across the country will begin to reach “climate departure”: a symbolic rubicon, after which a climate falls completely outside historical norms.
- Even the coldest year, going forward, will be hotter than the hottest in the past.
- The concept was defined in 2013 by researchers at the University of Hawai’i, who crunched computer models of 39 different planetary futures to arrive at their predictions.
- In a scenario consistent with roughly two degrees warming by mid-century,
- stats: start - Montreal is estimated to reach its departure point in 2072, - Toronto in 2074 and - Vancouver in 2083.

- comment
- the article doesn't mention two important points
- a number of places are expected to reach climate departure in the 2020's, such as
- Manokwari, Indonesia in 2020
- Lagos and Jakarta in 2029
- Even if we decarbonize at the most aggresive RCP pathway, it would not prevent climate departure, but only delay it by a few decades
- a number of places are expected to reach climate departure in the 2020's, such as
- The implications are profound. It means that the living organisms on most places on the planet will be on a path to extinction or migration. The entire biosphere will be in migration and this also has profound implications on human social and economic systems. Species whose livelihood billions of people depend on will be migrating to other parts of the environment, potentially devastating large swathes of local economies the world over.

you can imagine that that if that's happening today and climate change hasn't really even hit yet and biodiversity loss really hasn't even hit badly yet or at least this hasn't hit widespread 00:35:45 badly

comment
- There will be massive human migration
- Europe is already unable to cope with the migration of a million climate refugees from Syria
- The US is polarized due to mass migration of a few people escaping climate crisis and violence in central and South America
- Developed countries will be overwhelmed with climate refugees number in the millions or tens of millions
- In addition to human migration, the migration of species seeking cooler temperatures will fundamentally reshape our economies
- climate departure is the date when local climate goes outside normal historical bounds and locally adapted species do not recognize it anymore and will be forced to migrate to survive
- climate departure is a huge issue that is going to happen, regardless of which decarbonoization path we take. This means all species on the globe will be undergoing dramatic environmental shifts, making mass extinction more likely.
