It seems that President Trump's continuing war on climate science is going to adversely affect my own "#Arctic citizen science" work:

GreatWhiteCon.info/2025/05/tru

"I frequently post a summary of the Arctic section of the United States’ National Snow and Ice Data Center’s monthly review of the current state of the #cryosphere.

However, this month I have some additional bad news to report. According to a May 6th 'Level of Service Update for Data Products' from the #NSIDC:

'Effective May 5, 2025, #NOAA’s National Centers for Environmental Information (#NCEI) will decommission its snow and ice data products from the Coasts, Oceans, and Geophysics Science Division (#COGS).

As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported.

Sea Ice Index...

If you rely on these products in your work, research, education, or planning, we invite you to share your story at nsidc@nsidc.org. Your input can help us demonstrate the importance of these data sets and advocate for future support.'

If you are a resident of the US you may also wish to contact your local friendly neighbourhood politician(s) about the matter?"

'Cryosphere meltdown' will impact Arctic marine carbon cycles and ecosystems, new study warns

A new study led by Jochen Knies from the iC3 Polar Research Hub has found worrying signs that climate change may be undermining the capacity of #Arctic #fjords to serve as effective #carbon sinks. The findings suggest that the capacity of polar #oceans to remove carbon from the #atmosphere may be reduced as the world continues to heat up.

Knies and his collaborators discovered that rapid changes in the Arctic are transforming vibrant fjord ecosystems like Kongsfjorden in #Svalbard. Published in Communications Earth & Environment, their findings document not only a shift in phytoplankton communities due to melting ice but also a worrying decline in the capacity of these fjords to sequester carbon.

Warmer waters can enhance #phytoplankton growth during sunlit summers, presenting an initial opportunity for increased productivity. However, as the waters become stratified, essential nutrients become harder to access, leading to a double-edged sword: while we may see a rise in phytoplankton #biomass, the efficiency of CarbonCapture could decline.

A colleague points me to this interesting paper: How a changing #cryosphere makes it harder to achieve the UN's SDGs - because everything is connected...

NatureOpportunities and threats of cryosphere change to the achievement of UN 2030 SDGs - Humanities and Social Sciences CommunicationsThe cryosphere plays a critical role in maintaining the stability of the social-ecological system, but rapid cryosphere changes have been and are wide-ranging and have a profound affect, even threatening the achievement of the UN’s 2030 sustainable development goals (SDGs). In the study, we review the opportunities and threats caused by cryosphere changes in achieving the SDGs. The results reveal that cryosphere changes are significantly related to the supply of sustainable fresh water (SDG 6), alpine hydropower (SDG 7), and climate action (SDG 13). In addition, they favorably support life on land and below water (SDG 14-15), and effectively affect the livelihoods (SDG 1-5), agricultural development (SDG 2), snow/ice tourism (SDG 8), infrastructure (SDG 9), regional inequality (SDG 10), and cities and communities (SDG 11), as well as affecting Arctic shipping routes (SDG 16). Long-term cryosphere threats far outweigh their contributions to the SDGs. The cryosphere contributes little to human emissions, but it is significantly affected by climate change. Areas affected by cryosphere changes need to strengthen resilience and enhance the ability to adapt to the influences of cryosphere changes (SDG 1-17) via financial transfer, multilateral international cooperation, and other practical policies.

Just seeing a workshop call for ice sheet processes to be held on Stradbroke Island (near Brisbane, Australia), in July.

The optics are a bit odd (+fuel for rabid RWNJs.) If you're going to do a cryosphere meeting in Australia in July at least pick a place with fewer "public funded tropical holiday" vibes 🤷

BTW if you're planning for IGARSS this year to talk snow, hit me up. I prob. won't be attending - happy to talk ski tours before/ after and go dig some pits ;)

Mountains and Glaciers: Water towers
UN World Water Development Report

Mountain waters are essential to humans and ecosystems

The 2025 edition of the #UnitedNations World Water Development Report highlights the importance of #mountain waters, including alpine #glaciers, which are vital for meeting basic human needs such as water supply and sanitation. They are also essential to ensuring #food and #energy security to billions of people living in and around mountain regions and areas downstream. They also support economic growth through various water-reliant industries. As the ‘water towers’ of the world, mountains are an essential source of fresh #water. They store water in the form of #ice and #snow during cold seasons, releasing it during warmer seasons as a major source of fresh water for users downstream. Mountains play a unique and critical role in the global #WaterCycle, and they affect atmospheric circulation, which drives #weather and #precipitation patterns.

Deperate times need desperate measures but like hope desperation is not a working plan.

"...finding aligns with the assessment of the indigenous knowledge holders in Greenland: already before modeling was made, they expressed doubts on the effectivity of the curtain in Ilulissat Icefjord, because of surface melt."

More archive diving: A poster for the ISPRS 2012 conference I'd actually forgotten about. Apologies for the rainbowness 😬. At that point I was not able to push back about every single edit - it was already a radically unscientific poster design!

Fair warning: none of this is evidence of capacity to work in the geospatial or polar research sectors 🤷.
