Pssst - interested in some of the coolest #Arctic climate data you can get your hands on?

The @CopernicusEU Arctic regional reanalysis is now out: 40 years of super high resolution data including weather, sea ice, icesheet and glacier fields.

Full historical CARRA2 data release offers new insights into Arctic extremes | Copernicus

The Arctic is warming at more than twice the global average, making it an important region for monitoring climate change. To support better understanding of key regional processes and inform decision-making, the Copernicus Climate Change Service (C3S*) has released the full 40-year data series (1986-2025) from its second-generation Copernicus Arctic Regional Reanalysis – CARRA2, which is now a pan-Arctic regional reanalysis.

Orange rivers signal toxic shift in Arctic wilderness

Scientists say the warming climate is triggering chemical reactions that leach toxic metals into once-pristine Arctic waters, degrading fish habitat, water quality, and life for local people.

Way back in 2022, as the world tried to readjust back to "normal" following COVID - I helped to co-organise a bootcamp with sponsorhop from the @wcrp_climate IASC, @esaclimate and a generous dollop of help from @PolarRES and @dmidk colleagues.
We gathered 10 senior scientist mentors and 22 students in an old torpedo research station (now used by Roskilde University) for 10 days. It was an extremely intense period but the 4th paper produced by this talented group has just come out.
I consider facilitating #EarlyCareerScientists to work on important science problems an extremely rewarding part of my job, and I'm looking forward to the next one already as part of our PISCO project.

In the mean time, go and read this extremely cool work, collecting together a huge number of radiosonde observations going back to the 1950s over the Arctic Ocean and using them to assess how well CMIP6 models represent lower atmosphere.

✊💙 This is a call to action

We cannot afford to stand by while one of the world’s last great wildernesses vanishes. Join us at Glacierwatch to help protect what remains of this fragile, beautiful ecosystem. Together, we can still make a difference.
