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.
