Simulierter AMOC Kollaps vor-industriell und unter RCP4.5 (580 ppm) CO2. Paper: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025GL114611

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.

Was in Deutschland passiert, wenn der Golfstrom versiegt Die Atlantische Umwälzströmung wird laut Experten rapide schwächer. Ein Kollaps könnte Europa völlig verändern. Doch welche Folgen drohen ganz konkret? Zwei Klimaforscher schildern ntv.de, worauf wir ...

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.

Time series graph showing the duration of longest heatwave event in Sodankylä Tähtelä. The values range generally between 0 and 14, but in 2025 the heatwave has now lasted for 26 days.

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.

A really beautiful core! And welcome on the platform with your first posting 👍🧪 ⚒️

Why you should write your PhD thesis backwards By considering the central statement of your entire PhD, you can structure your writing around it, says Tuuli Toivonen.

Is there evidence for the tags having the desired effect?
