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?)

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:

Ein Kollaps der warmen Meeresströmung im Atlantik (#AMOC) hatte extreme Auswirkungen auf Europa. Neuere Simulationen zeigen, dass dies auch unter hohen CO2-Werten (RCP4.5) der Fall wäre. Die Frage ob und wann es zu einem Kollaps kommt, ist noch umstritten. www.n-tv.de/wissen/Was-i...

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.
