🌍 Berkeley Earth’s 2025 Global Temperature Report is out. 2025 was the 3rd warmest year on record. Annual global temperature reached 1.44 ± 0.09°C above the pre-industrial baseline; 770 million people experienced locally record-warm annual conditions. Full report: berkeleyearth.org/global-tempe...

The global warming trend continued in 2025. Each of the past 11 years (2015–2025) has been among the 11 warmest on record. Explore more data from #CopernicusClimate in the Global Climate Highlights 2025. #GCH2025 🔗 climate.copernicus.eu/global-clima... @ecmwf.int

Great article on the threats facing the Scandinavian tundra 🌍❄️ (in Swedish). Proud to have contributed with background insights! 🙌 #ClimateChange #Tundra www.dn.se/sverige/fakt...

Climate change has already reshaped the bioclimatic space of extreme events in the Arctic 🌐❄️ Arctic biodiversity has entered a new era of bioclimatic extremes w/ more droughts, greater winter-warming 📈 & more rain-on-snow events 💧❄️ shorturl.at/pQsVP Just published in Science Advances ⬇️

Love seeing @plosclimate.org highlighting our Browning review in their #PLOSClimateCountdown.

🚨New paper in @ecography.bsky.social! First Pan-Arctic study on how large herbivore exclusion shapes mycorrhizal fungi, brilliantly led by @colebrachmann.bsky.social. Key insight: AM fungi—often overlooked in Arctic research—respond most strongly to herbivory while EcM and ErM vary locally. Thread 👇

This opportunity looks amazing—don’t miss out, apply today!

Thrilled to announce that our Polar Research School has secured funding! 🌍❄️ This means 15 new PhD studentships will soon be connected to the program. Stay tuned for updates! 🔗https://www.vr.se/english/applying-for-funding/decisions/2025-11-05-doctoral-programme-grant-within-polar-research.html

The Swedish tundra has historically lacked a wildfire regime, making it ecologically unique. However, climate-induced shifts are now elevating fire risk. I commented on these emerging dynamics on @svtnyheter.bsky.social this morning.🔥🌍 #ClimateChange #WildfireRisk #Arctic www.svt.se/nyheter/loka...

Another exciting day in the ReindeerFlux project!🦌 Frida and @colebrachmann.bsky.social measured CO₂ & CH₄, while Alex and Johan flew drones with radar, multispectral & NDVI sensors. Thanks @svtnyheter.bsky.social’s Susan & Henrik for visiting—loved sharing our work in beautiful Grövelsjön! 🌿

Honored to have served on the award committee for the Sixten Heymans Prize 🏅 We made an excellent choice in naming Kirsten Knudsen the 2025 laureate 🌟 Her research on star-forming galaxies at cosmological distances is truly fascinating 🔭✨

I've put together this Starter Pack because I still miss connecting with many Arctic colleagues on this platform. Apologies if I missed adding some of you, but you're all welcome to join! go.bsky.app/KRYFusr

🎓 Our final APE@GU undergrad spotlight of the year is on Ingrid! 🌟 She established and refined our ergosterol protocol to better understand how reindeer affect mycorrhizal mycelium production. 🦌🍄 Fantastic work, Ingrid — way to go! 👏🎉 #Arctic #Mycorrhiza #BScThesis

Huge congratulations to Julia on a fantastic BSc thesis and a skillful defense! 🎓👏 You've shed new light on how mycelial production is influenced by different forest management strategies. 🌲🍄 #ForestEcology #Mycorrhiza #BScThesis

Fantastic introductory seminar by our new PhD student Emil Larsson! 🛰️ He’ll be exploring how hyperspectral satellite data can unlock new insights into Arctic biodiversity ❄️🌱. Excited to follow his journey — and to learn a lot along the way! 📚✨

Huge congratulations to Maja on an outstanding MSc thesis! 🎓🦌 Your work has shed new light on how reindeer influence methane (CH₄) fluxes in the Scandes mountains — a valuable step forward in understanding Arctic greenhouse gas dynamics.

Congratulations Malin on a very well-executed MSc thesis. Now we know a little more about how reindeer 🦌 affect CO2 fluxes in the Scandes mountains 🏔.

Windy first field day for the season in Grövelsjön for our @vetenskapsradet.bsky.social project on reindeer-climate feedbacks. Busy with CO2, CH4, BVOC fluxes, NDVI measurements, teabags installation & more! With @colebrachmann.bsky.social, @riikkarinnan.bsky.social and @heatherreese.bsky.social.

All set for a new field season, launching tomorrow. Let’s go! 💪🌿🦌🪻🏔
