Researchers from @stockholm-uni.bsky.social and @bolincentre.bsky.social have used deep learning and satellite data to classify 43 Swedish wetlands into five distinct hydrological regimes—and link them to ecosystem services. Access the paper, published in @egu.eu Hydrology & Earth System Sciences.👇

För att bättre förstå effekter på klimatet av tinande permafrost i Arktis kommer Gustaf Hugelius @bolincentre.bsky.social m fl forskare i ett nytt @erc.europa.eu-projekt börja tina upp mark i Finland. Resultaten är tänkta att medräknas i klimatprognoser. #Klimat www.sverigesradio.se/artikel/fors...

Big congratulations to our deputy director Gustaf Hugelius, who was just awarded a ERC Syngergy Grant for the project “Northern Peatlands in the face of climate warming and abrupt changes (CLIMPEAT).” 👏

This is why we are relaunching the scientific journal #Tellus — to strengthen open, researcher-led publishing. “We want to promote learning and careful scientific communication” says director Ilona Riipinen. Read the article below.👇

Klimatmötet COP30 i Brasilien blir en påminnelse om ett grundläggande problem: Politikerna behöver aktuella vetenskapliga underlag, men får dem för sällan och vid fel tillfällen. Klimatforskarna Örjan Gustafsson och Svante Bodin föreslår tre reformer för att lösa problemet. vist.ly/4cxw7

Pulitzer-winning writer @elizkolbert.bsky.social visited the Bolin Centre & @stockholm-uni.bsky.social to explore how Svante Arrhenius’s 19th-century ideas still shape our understanding of global warming and climate change. Read about her visit and upcoming project on our website. 👇

Lignin diversity helps plants thrive on land – without them, they become small, sterile plants that produce far less biomass. 🪴 This is revealed in a new study in @newphyt.bsky.social by @stockholm-uni.bsky.social @bolincentre.bsky.social @uspoficial.bsky.social & #TUAT 👇

Varmare och torrare somrar gör skogarna mer sårbara för granbarkborrar. En ny studie av bl a Caroline Greiser, Stockholms univ, visar att angreppen höjer temperaturen i drabbade områden. Men lövträd pekas ut som lösningen på uppvärmningseffekten. @bolincentre.bsky.social www.svt.se/nyheter/loka...

Dandelions that clone themselves still make pollen, but why? The #NoSexPoorPollen project led by @yannickwoudstra.bsky.social studies how pollen degrades when it’s no longer needed for sex, and what that means for evolution 🌼 Learn more about the project below!

New study out in @science.orgs Science Advances! 📣 The uplift of East Africa during the Miocene epoch dramatically transformed the region’s climate and ecosystems, promoting the expansion of grassland and reshaping habitats for mammals and early hominoids. 👇 @stockholm-uni.bsky.social @ethz.ch

Correction: the record minus year was 2024, not 2022. Should also be corrected now at SverigesRadio's site. And Time Lapse Camera imagery from 30 minutes ago shows snow in the Tarfala Valley :) @stockholm-uni.bsky.social @bolincentre.bsky.social

Det är viktigare än någonsin att följa glaciärerna i detalj, menar glaciologen Nina Kirchner. F&F besökte henne på Tarfala forskningsstation och fick följa med till världens mest undersökta glaciär. vist.ly/47uws

New in @oikosjournal.bsky.social! 📃 The study, led by Peter Hambäck at DEEP, explores how interactions between hosts and enemies shape biodiversity. Results show that bottom–up and top–down diversification don’t work the same way, and that parasitoids often adapt faster than their hosts.👇

And here comes the snow ❄️ Summer is indeed short: Left: today. Middle: 14 june. But there WAS summer in between (Right) 😀Last post from the station tomorrow @stockholm-uni.bsky.social @bolincentre.bsky.social

First nightfrost, followed by a beautiful sunny morning, captured by our Time Lapse Camera at #LakeTarfala. These are the last days before closing the station @stockholm-uni.bsky.social @bolincentre.bsky.social after more than 3 months of 24/7 operation👍 #glacier #massbalance results to come soon!
