Researchers Conclude Climate Change Worst-Case is 'Implausible'
A recent report from a UN body of researchers has deemed the extreme climate change scenario known as RCP8.5 as 'implausible.' This scenario, which predicted dire consequences from unchecked fossil fuel consumption, has influenced climate assessments and policies globally. Experts clarify that RCP8.5 was always intended as a worst-case scenario rather than a likely outcome.
- ▪The UN researchers announced that the worst-case climate scenario RCP8.5 is no longer plausible.
- ▪RCP8.5 was originally intended to represent a high-end, no-climate-policy scenario.
- ▪The scenario has influenced national climate assessments and decisions made by central banks worldwide.
