A #winterstorm2021 down to South #Texas?
Usually a strong polar vortex confines Arctic air to the north. It's stabilized by a high temp. gradient between low & high latitudes. The lower the gradient, the more the wind belts meander, transporting cold air south/warm air north.
1/3 Of course this happened from time to time in the past, but the more Global Warming will cause the Arctic to warm more relative to the mid latitudes (Arctic amplification), the more common this phenomenon might become.

The sea north of Greenland is where we usually find the thickest, multiyear sea ice. This year...was different. Polarstern could steam with 5-7kn even above 88°N! Reaching the North Pole yesterday surrounded by thin ice, littered with melt ponds.

1/4 Sheltered by the landlocked layout of the Arctic Ocean multiyear sea ice can form and is being pushed toward the northern waters off Greenland.

@TerliWetter @MartinStendel OK, sorry bin jetzt erst dazu gekommen die Studie zu lesen.
nature.com/articles/s4324…
Wie die Abbildung zeigt, haben wir seit Anfang des Jahrtausends ein neues Gleichgewicht zwischen Schneefall und Akkumulation also Aufbau der Gletscher im Inland und Eisverlust durch Kalbung
1/n @TerliWetter @MartinStendel Das bedeuted, wenn wir jetzt aufhören würden weiter CO₂ in die Atmosphäre zu pumpen und eine weitere Erwärmung stoppen könnten, wäre das grönländische System weiterhin im neuen Zustand in dem es sich seit Anfang der 2000er eingependelt hat

Snow in Central Park, in May? This clearly disproves #GlobalWarming, and climate scientists will claim it’s “just” weather, right?
Well, 1) No! and 2) Yes…and No!
Lets dive into this!

 CO₂ is a very potent greenhouse gas, and over the years we have pumped A LOT of it into the atmosphere. This warms the entire globe, but due to a process called Arctic Amplification, the Arctic warms way faster than the rest.

Guter Punkt. Hier meine Mittagspausenantworten auf die sog.#Klimafragen. Einiges lässt sich von mir jedoch nicht beantworten ohne Entscheidungsprozesse des Bundestages zu kennen.

 F1) Klimamodelle rekonstruieren aktuellen Klimawandel und stimmen sehr gut mit Beobachtungen überein. Für die Vorhersagen wird zudem das Wissen vergangener Klimaänderungen mit einbezogen.

A favorite argument of climate change deniers is that plants need CO₂. Hence more CO₂ is better, or is it?
While plants might grow faster under high CO₂ levels and produce more carbohydrates, at the same time the amount of vitamins and micronutrients is declining.

1/n Field and experimental studies on wheat and rice showed that protein declines by ~10%, iron by ~8%, zinc by 5%. B-vitamins will decline by up to 30% under increased CO₂ conditions
