What’s in a number? The significance of the 1.5°C warming threshold and reporting on its possible breach in popular media
These findings were widely covered by popular media outlets, including in articles published by The Guardian, CNN, and BBC, which all reported that this temperature increase would represent a breach of the key IPCC threshold. However, this is missing some important context.
“A single year above 1.5°C does not mean the world has passed that particular warming level”, said Zeke Hausfather. Such nuance was better captured by articles published in Reuters and Axios, which both correctly did not report that these new temperature projections, if realized, would constitute a breach of the threshold.
