The 2026 line ran off the top of the Niño 3.4 chart, so Climate Reanalyzer had to raise the ceiling from 30°C to 31°C. Ocean temps in the heart of this El Niño are running about 3°C above the early October average and higher than any other year on record for this time of year.

Shocking: Trump officials are offering $2,500 or more to detained teens as young as 14 if they agree to leave the US. Kids also get a memo threatening long detention, and prosecution of noncitizen parents, if they press their legal case: “You will be detained for a prolonged period of time.”

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.

~426.0 ppm: September average of atmospheric CO2 at Mauna Loa, estimated from daily values. That's another ~1.7 ppm higher than last year. September is the lowest point in the seasonal cycle, and we won't see a value this low (but extremely high) for many generations to come.
13 months of daily, weekly, and monthly values, showing the seasonal swing with an underlying increase. September is the lowest point in the seasonal cycle.

Line graph time series of global land mean surface temperature anomalies for each January-August period from 1850 through 2026. There is a long-term increasing trend and large year-to-year variability. The mean surface temperature anomaly averaged for January-August 2026 was 1.16°C for global land areas. Anomalies are computed relative to a 1901-2000 climate baseline. Data from NOAA/NESDIS/NCEI NOAAGlobalTemp v6.1.0.
