Preparations for this project have been going on for months:
- fitness and medical examinations to make sure we are mentally and physically fit enough to go to the Antarctic.
- building and testing weather stations.

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.

The answer: mitigation. Depending on what we do in the next decades, we can still reduce risks.
If we dramatically reduce GHG emissions, we can slow and decrease the amount of weakening, buy time for adaptation, and potentially still avoid an AMOC collapse.

Consequences of collapse are potentially devastating, with winters in Northern Europe becoming significantly colder.
Other potential effects: more active storm track in NW-Europe, less precipitation & rapid increase in local sea level.
Current systems & infrastructure not ready for such changes.

Lectures on AMOC and consequences of collapse by experts like René van Westen,
@rahmstorf.bsky.social, @swinda.bsky.social, @helmiraisanen.bsky.social.
Main conclusions: AMOC weakening is observed, further weakening virtually certain. Pace of weakening, and if/when AMOC collapses remain uncertain.

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.

Northern lights were briefly but strongly visible from Helsinki - even with the bare eye.

It's also the first frost of the fall in the city centre of Helsinki (Kaisaniemi). Timing of this season's first frost is relatively typical.

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.

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. 🔋
High-power chargers ⚡️:
• Inari 🇫🇮 – 2× 300 kW
• Kople & Tana 🇳🇴 – 175 kW
• Utsjoki 🇫🇮 – 4× 200 kW

Timing of the first frost is relatively typical, maybe slightly early in the current climate.

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.

The main message during my presentations in Longyearbyen last week: Svalbard is losing it's polar climate.
The timing of Schuler et al.’s new study couldn’t have been better: I could show this figure illustrating how last summer’s record heat will be the new normal within decades.

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.

I already found it surprisingly chilly this morning, but it makes sense now I see this!
A return time of >30 years, according to FMI's statistics. Quite impressive!
