This year's El Niño continues its climb into uncharted waters; Niño3.4 region anomalies are now at a 3.4C above normal (how fitting!), higher than any prior El Niño event on record. September monthly Niño3.4 anomalies also set a record at 2.9C (beating 2015 and 1877's 2.75C).

Historic warmth is currently impacting our global oceans. September shattered the previous peak for the warmest average global sea surface temperature on record for the month. And this excessive heat is found across nearly all regions. Data from NOAA ERSSTv6. I finally adjusted the y-axis here. 🌊
Green line graph time series of average sea surface temperature anomalies for each September from 1900 through 2026. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline.

I often see people argue that clean energy is not reducing emissions, because it just adds to rather than replaces fossil fuels. This argument is deeply misguided – clean energy built since 2005 has displaced 23 billion tons. I dive in over at The Climate Brink:
theclimatebrink.com
What if the world hadn't built wind and solar?
Clean energy does not simply “add to” global energy use; it displaces fossil sources that would otherwise get built.
