“Varmt” vand tærer på havisen. Efter en meget varm sæson i Arktis er udbredelsen af havis nu på det næst-laveste niveau, og kun tiden vil vise om minimums-rekorden fra 2012 står for skud, eller om isudbredelsen 2020 indtager andenpladsen. dmi.dk/nyheder/2020/v… #havis #klima

Næstlaveste havis-udbredelse i over 40 år😳🌡️ En varm sæson i Arktis har taget hårdt på havisen og sendt den ind på sikker og kedelig 2. plads over mindste isdække siden målingerne startede for over 40 år siden. Læs mere her: dmi.dk/nyheder/2020/n… #klima #arktis #havis

The Arctic Ocean is taking its time to freeze-up with the total ice extent approaching that in 2012, and as a result, air temperatures are at least 6C warmer than average over the entire Arctic... what a year 2020 has been! psl.noaa.gov/tmp/composites… National Snow and Ice Data Center @CeosUofm EarthSciences UCL

HISTORISK KLIMA-EKSPEDITION I ARKTIS ER SLUT🚢 I dag ankommer isbryderen #Polarstern til Bremerhaven, og det største flydende havis-eksperiment nogensinde er slut. Læs om #MOSAiCekspeditionen og tidligere skelsættende ekspeditioner her: dmi.dk/nyheder/2020/h…

Havisen i Arktis er rekordlav for årstiden, og det går langsomt med at fryse til igen. Især i den østlige del af Arktis. Problemet er for høje hav- og lufttemperaturer. #klima #dkgreen

DEN ARKTISKE HAVIS VOKSER SIG TIL EN NY BUNDREKORD Væksten af havis i Arktis foregår meget trægt i år, og lige nu er isudbredelsen rekordlav for årstiden. Der er tale om en ond spiral, hvor den globale opvarmning rammer Arktis særligt hårdt. 👉dmi.dk/?id=1891

Combining satellite infrared, microwave radiometer and altimeter data to retrieve snow and sea ice thickness! The work continues DMI I am happy to be part of it.

STORT TILLYKKE MED RITZAU PRISEN TIL DMI'S HAVISFORSKER Rasmus Tonboe Rasmus hyldes for sin deltagelse på den hidtil største arktiske ekspedition 'MOSAiC-ekspeditionen' og for hans store dedikation til at forske i globale klimaforandringer. Læs mere her: adventurefilmfest.dk/ritzau-prisen/
