Global Temperatures Down In December; Ice And Snow Disruptions Across Europe; Sierra Turnaround; Arctic Ice Rebounds; Another Average Hurricane Year; + $6.4 Trillion Spent, Fossil Fuels Still Rule
Global temperatures have returned to pre-eruption levels just as Solar Cycle 25 slides toward its minimum. All eyes on what follows.
Global Temperatures Down In December
UAH satellite data show the global lower troposphere anomaly fell to 0.30C (0.54F) in December 2025, down from 0.43C (0.77F) in November, reinforcing the ongoing reversal since the 2024 Hunga Tonga/El Nino-driven spike.
Satellites measure the atmosphere directly, avoiding surface station bias, urban heat contamination, and agency homogenization ‘adjustments’.
They now show clear (and expected) cooling following the 2022 eruption of Hunga Tonga — a massive submarine explosion which injected an unprecedented volume of water vapor into the atmosphere that still lingers today (though waning).
December’s value sits us back in the long-term range. Similar anomalies occurred throughout the 2010s, 2000s, and even the 1990s — despite steadily rising CO2 concentrations. We’re even roughly on par with December 1987.

Ice And Snow Disruptions Across Europe
Europe has been plunged into a sharp winter freeze, with widespread severe cold and disruptive snowfall stretching from Scandinavia through France, Germany, the Balkans and into Turkey.
