#Globalwarming doesn't stop without cutting CO2 emissions. "24 hours for the climate" in Stockholm ended with a huge march to the parliament today. Over 50.000 participants, 280 registered organisations & scientists from all over Sweden sent a kind reminder. The march was non-partisan.

Noctilucent Clouds over Stockholm on 20 July 2026. These Polar Mesospheric Clouds (PMCs) are the highest clouds on Earth at ~80 km altitude. They form from small ice crystals where the water stems from Methane reacting with hydroxyl radicals (OH) + dust particles of unknown origin (micrometeors?)

After a thunderstorm moved through at the (current) end of a major heatwave, quasi-stationary convection remained at the coast for almost an hour with impressive clouds. With stronger convection igniting deep convection further inland, the coastal convergence collapsed.

The latest CFSv2 model results for El Nino (ONI) anomalies later this year are kinda nuts, with a peak at nearly 3.9C in November. NOAA needs to once again raise the y-axis range; here is what it should look like without all the runs above 4C cut off:

Das ist richtig für die Mittelwerte. Richtig sibirisch würde es unter heutigen Bedingen v.a. in Skandinavien. Dies hängt davon ab, wie weit das Meereis nach Süden vorstößt. Bemerkenswert ist, dass selbst mit deutlich erhöhten CO2-Werten (580 ppm, RCP4.5) das Meereis weit nach Süden reicht.

The heatwave in Sodankylä has now lasted for 26 days. This is probably not only the longest heatwave in Lapland, but also the longest heatwave ever observed in Finland. Note that here a heatwave is defined with 3 consecutive days above 90th percentile, which is scientifically robust definition.
