David Attenborough [whispering]:
“As the predators close in on their helpless prey, we can only watch in silent horror, for it is not man’s role to interfere in the hierarchy of nature.”
❄️Theory and practice❄️
In Sisimiut, Greenland, we teach a DTU course called Extreme Climate and Physical Nature on the Arctic Semester. Earlier this week 30+ students practiced drilling in the ice on the lake in the center of town after learning the theory last week.
#CryoTeaching #ArcticDTU
Arctic DTU has moved to a new campus building in Sisimiut. Saw it for the first time today. It is very…. Green! 🤩💚

Our PhD Student @mikkelaabykruse.bsky.social is currently getting a taste of what it is like to do fieldwork in the Arctic at The University Centre in Svalbard (UNIS)❄️🥽 🧤 Working on a glacier is no safe or easy task, and UNIS is a great place to learn the ropes of what it means to be a glaciologist!
🚀 Excited for Copernicus @esa.int #CRISTAL! This mission’s dual‑freq Ka/Ku #altimeter aims to measure snow depth on sea ice. A new UiT‑led study (feat. @reneefredensborg.bsky.social) explores current laser/radar data + simulates CRISTAL waveforms. Check it out ➡️ tc.copernicus.org/articles/20/... ❄️🧊

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.
Which just makes me want to share it again: www.nature.com/articles/d41...

🛰️BIG NEWS! NASA has selected a
@ucsandiego.bsky.social led satellite mission for the Earth System Explorers program. Led by Scripps Oceanography glaciologist @helen-amanda.bsky.social, Earth Dynamics Geodetic Explorer (EDGE) is one of two next-generation satellite missions selected. 🧵⤵️

Most people are worried about climate change - but most don't hear or talk about regularly.
That's why I started my free newsletter Talking Climate. Every week I share good news, not so good news, and what people can do.

🍾🥂One of our most exciting pieces of news this month must be the hand-in of Anna Puggaard's PhD thesis on "Earth observation for surface mass balance" on January 15, celebrated with cake and bubbles! We look forward to seeing her in the office as a postdoc in February, after a well-deserved break! 🏝️
Such an important (and once hidden) figure in satellite geodesy and ocean altimetry.

Fires across the Ñuble and Biobío regions have burned more than 8,500 hectares (21,000 acres). Hot, dry, and windy conditions have accelerated the spread: bit.ly/4qYFbVo

Bar graph showing global ocean heat content change in the upper 2000 m from the late 1950s through 2025. There is a long-term warming in the time series, which is using IAP/CAS data.
2025 was the hottest year on record for ocean heat content. Unfortunately, we now say this every year. 🥹
"In addition to setting a new record in 2025, the global
ocean continues to show sustained and intensified warming."

@mikkelaabykruse.bsky.social is a PhD student in the Cryo Group. He uses satellite remote sensing to study lakes hidden beneath the Greenland Ice Sheet 🛰️🧊🌊 Some of these lakes can contain and later release enormous amounts of meltwater. #Cryosphere #RemoteSensing #Greenland
To round off the year and just before Christmas, I had the amazing opportunity of spending the last week in Calgary, Alberta, meeting my colleagues at @ucalgary.bsky.social while participating in the ArcticNet's Annual Science Meeting #ASM25, and presenting my #MEOPAR funded project #SNOWMASS ❄️🛩️🛰️! ➡️

How many glaciers will exist by 2100 at +1.5 °C vs +4 °C warming? Our new study led by @landervt.bsky.social , projects the extinction year of ~200,000 glaciers worldwide. 🌍🧊
Can you imagine the Alps with only 20 glaciers remaining?

Heading South
But not for the warmth.. Tomorrow I'm taking the first stage of the journey to Antarctica, ironically enough though, I'm heading south by first heading north, to Oslo, where the Norwegian Polar Institute have organised an almost direct flight from Oslo to Troll station with a short…
I hope that you have an amazing field campaign. 😊
Our colleague @tabea-rettelbach.bsky.social is developing dynamic data cubes for #EO data over ice sheets (literally 🧊). The goal is to make complex geospatial datasets easier to find, access, and use for e.g. modelers. #datacubes @icelink-project.bsky.social #PISCO #DTC_icesheets
A message much better stated than I could say it, but which I try to give to ECRs I work with. There are seasons in research and sometimes it is harvest time, but sometimes the seeds are just sitting in the ground resting and waiting for Spring. www.joanwestenberg.com/the-harvest-...
