The latest IPCC guidance on when carbon emissions should peak has been misunderstood say scientists.
focussed on how to limit or curtail emissions of the gases that are the root cause of warming.
This will take a herculean effort, with carbon emissions needing to shrink by 43% by the end of this decade to stay under this threshold of danger.But before they fall, emissions need to reach a peak - and it's in the text explaining this idea that the report becomes confusing. Most media outlets including the BBC concluded that meant emissions could rise until 2025 and the world could still stay under 1.5C.
"It's an unfortunate choice of wording. That is, unfortunately, going to potentially have some rather negative consequences."It's partly because the climate models that scientists use to project temperatures work in five-year blocs, so 2025 follows 2020 for example, without reference to the years in between.
