In less than 2 weeks I will be departing to the Antarctic! I will spend a month at the Mario Zucchelli Station🇮🇹, the base for our field work on the Nansen Ice Shelf.

Both EC and AIFS are hinting to colder weather in Northern Europe next week.
Helsinki will see frosty nights. There's a small chance for the first frosty days, too.

Een jaar na de ramp in Valencia blijkt: de overstromingen waren zo'n 20% natter door klimaatverandering.

Dit is de link tussen Valencia’s dodelijke overstromingen en klimaatverandering
Een jaar geleden werd Valencia getroffen door uitzonderlijke overstromingen. Meteorologen becijferden in hoeverre dat is toe te schrijven aan klimaatverandering.

En of het verhaal van klimaatverandering en opwarmende wereld nog niet genoeg is. Door die opwarming kan de #AMOC (belangrijke oceaanstroming in de Atlantische Oceaan, een soort super warmtepomp) sterk verzwakken of zelfs stilvallen. In welk geval het hier (NW Europa) veel kouder wordt. Zie draadje.
Great, intense conference during the Nordic Tipping Week in Helsinki and Rovaniemi 🇫🇮 last week.
Climate scientists, fisheries experts, social researchers, and policy makers came together to discuss what an #AMOC weakening or collapse could mean for the Nordic region and the rest of the world.

First snow of the season in Finland has fallen today morning in Enontekiö, Lapland.
This year, the first snow was about three weeks late. Usually the first measurable snow is registered somewhere in the country in late September.

Parts of Northern Norway and Finnish Lapland will see the first snow of this autumn in the upcoming days.
Cold, northwesterly flow over relatively warm sea surfaces leads to the formation of these showers.

Last week, Longyearbyen (Svalbard) recorded its highest October temperature on record: 10.2°C, just above the 10.1°C set in 2016. 🌡️
Now, just days later, winter has finally taken over❄️ - but the temperatures remain on the mild side for this time of year.

Wow, autumn-to-date mean temperature in Sodankylä, Lapland is currently a full two degrees (!) higher than the previous record.
In Sodankylä, records have been kept since 1908.

Yesterday we drove this loop through some of the most remote parts of Finnish & Norwegian Lapland, yet EV charging wasn’t a problem at all. 🔋

• Inari 🇫🇮 – 2× 300 kW
• Kople & Tana 🇳🇴 – 175 kW
• Utsjoki 🇫🇮 – 4× 200 kW

So this is pretty amazing - yesterday EarthCARE sampled Hurricane Humberto straight across the eye! The eye of a tropical cyclone is small so a direct hit is rare: this is the first time EarthCARE has hit one after over a year in orbit! (Showing here also VIIRS on NOAA-20 for context.)

Windy day ahead tomorrow. One major factor is the powerful jet stream that facilitates cyclogenesis. Not so often we'll have 90 m/s wind speeds above us.

The summer as a whole was the 4th warmest on record. Note how the top 4 warmest years all occurred during the last 4 years.

Another extremely warm August on Svalbard. If it looks tame, that's only because last year obliterated the records.

PS. the current summer is on track to become the 5th warmest on record on Svalbard.
Substantially less warm than last year's, but note that up to 2020, a summer temperature like this was never measured.

Do you remember last year's crazy summer temperatures on Svalbard?
A new study by Schuler et al., published this week, finds that by the second half of this century, summers as warm as last year’s will be normal, or even relatively cool.

Our latest research investigates the remarkable heatwave that affected part of the Arctic in the summer of 2024. It caused a 1 percent loss in Svalbard's ice, making this region one of the most significant contributors to global sea-level rise last year www.pnas.org/doi/10.1073/...
