Warmest September on record as 'gobsmacking' data shocks scientists - BBC News
Based on the Copernicus Climate Change Service.
It's a short set, only 85 years (for monitoring Paris agreement), but what's given concern is that it's the largest ever increase on a previous year and is up 1.75 on pre-industrial temperatures (that's not in itself as a single month going to breach the COP target, but it's not a great direction of travel)
We're also perhaps heading for the warmest year ever, as globally the year to September is up 0.05 on the previous warmest year (2016) - not the year that had the second warmest September compared to 2023, that was 2020, but the one that had the second greatest increase on the previous year)
PS: anyone know how they set the average on the graph? It looks like they must have taken an older figure. The fairly steady rises begin around 1980
