Jeff MunroeHere at <a href="https://fediscience.org/tags/EGU25" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EGU25</a> my student Alex Takoudes just gave a great talk on his undergraduate thesis applying an image segmentation algorithm in a deep learning architecture to automate the mapping of rock glaciers. If you’re interested, you can find his results here: <a href="https://atakoudes.users.earthengine.app/view/takoudes-rock-glacier-thesis" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://atakoudes.users.earthengine.app/view/takoudes-rock-glacier-thesis</a> Nice job Alex! <a href="https://fediscience.org/tags/geology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#geology</a> <a href="https://fediscience.org/tags/cryosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cryosphere</a> <a href="https://fediscience.org/tags/RemoteSensing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RemoteSensing</a> <a href="https://fediscience.org/tags/rockglaciers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rockglaciers</a> <a href="https://fediscience.org/tags/utah" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#utah</a>

O=C=O'Cryosphere meltdown' will impact Arctic marine carbon cycles and ecosystems, new study warnsA 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 <a href="https://climatejustice.social/tags/Arctic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Arctic</a> <a href="https://climatejustice.social/tags/fjords" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fjords</a> to serve as effective <a href="https://climatejustice.social/tags/carbon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#carbon</a> sinks. The findings suggest that the capacity of polar <a href="https://climatejustice.social/tags/oceans" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#oceans</a> to remove carbon from the <a href="https://climatejustice.social/tags/atmosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#atmosphere</a> 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 <a href="https://climatejustice.social/tags/Svalbard" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Svalbard</a>. 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 <a href="https://climatejustice.social/tags/phytoplankton" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#phytoplankton</a> 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 <a href="https://climatejustice.social/tags/biomass" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biomass</a>, the efficiency of CarbonCapture could decline.<a href="https://phys.org/news/2025-04-cryosphere-meltdown-impact-arctic-marine.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://phys.org/news/2025-04-cryosphere-meltdown-impact-arctic-marine.html</a><a href="https://climatejustice.social/tags/ClimateScience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateScience</a> <a href="https://climatejustice.social/tags/ClimateCrisis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateCrisis</a> <a href="https://climatejustice.social/tags/Cryosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Cryosphere</a>

O=C=OMountains and Glaciers: Water towers UN World Water Development ReportMountain waters are essential to humans and ecosystemsThe 2025 edition of the <a href="https://climatejustice.social/tags/UnitedNations" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#UnitedNations</a> World Water Development Report highlights the importance of <a href="https://climatejustice.social/tags/mountain" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mountain</a> waters, including alpine <a href="https://climatejustice.social/tags/glaciers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#glaciers</a>, which are vital for meeting basic human needs such as water supply and sanitation. They are also essential to ensuring <a href="https://climatejustice.social/tags/food" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#food</a> and <a href="https://climatejustice.social/tags/energy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#energy</a> 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 <a href="https://climatejustice.social/tags/water" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#water</a>. They store water in the form of <a href="https://climatejustice.social/tags/ice" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ice</a> and <a href="https://climatejustice.social/tags/snow" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#snow</a> 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 <a href="https://climatejustice.social/tags/WaterCycle" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WaterCycle</a>, and they affect atmospheric circulation, which drives <a href="https://climatejustice.social/tags/weather" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#weather</a> and <a href="https://climatejustice.social/tags/precipitation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#precipitation</a> patterns.<a href="https://www.unesco.org/reports/wwdr/en/2025" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.unesco.org/reports/wwdr/en/2025</a><a href="https://climatejustice.social/tags/Environment" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Environment</a> <a href="https://climatejustice.social/tags/ClimateCrisis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateCrisis</a> <a href="https://climatejustice.social/tags/Cryosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Cryosphere</a>

O=C=O‘Catastrophic’ 2023 lake outburst in India driven by glacial melt and permafrost thaw<a href="https://climatejustice.social/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateChange</a> played a key role in the “catastrophic” 2023 floods in the Himalayan state of Sikkim in <a href="https://climatejustice.social/tags/India" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#India</a>, a new study says. The breach of one of the “largest, fastest-growing and most hazardous” glacial lakes in Sikkim, the South <a href="https://climatejustice.social/tags/Lhonak" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Lhonak</a> lake, led to cascading floods that killed 55 people and washed away a 1,200 megawatt (MW) <a href="https://climatejustice.social/tags/hydropower" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hydropower</a> dam. The event was identified as a glacial lake outburst flood (<a href="https://climatejustice.social/tags/GLOF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GLOF</a>), which is a sudden release of water from a lake fed by glacial melt. <a href="https://climatejustice.social/tags/Sikkim" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Sikkim</a> is a small Himalayan state in north-east India, bordering <a href="https://climatejustice.social/tags/China" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#China</a> in the north, <a href="https://climatejustice.social/tags/Bhutan" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Bhutan</a> in the east, <a href="https://climatejustice.social/tags/Nepal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Nepal</a> in the west and the state of West <a href="https://climatejustice.social/tags/Bengal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Bengal</a> in the south.

As the tundra continues to thaw and the flow of submarine groundwater ratchets up, Demir said that the outflow of carbon from shore to sea could effectively make ocean surface waters a carbon source to the <a href="https://climatejustice.social/tags/atmosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#atmosphere</a>.

Doug BostromOne way the US "energy emergency" will unfold, if successful."Under a high-end forcing scenario, the sea ice of the Last Ice Area thins and becomes more mobile, resulting in a large export southward. Under this potentially worst-case scenario, sea ice of the Last Ice Area could disappear a little more than one decade after the central Arctic Ocean has reached seasonally ice-free conditions. This loss would have profound impacts on ice-obligate species."<a href="https://scicomm.xyz/tags/cryosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cryosphere</a><a href="https://www.nature.com/articles/s43247-025-02034-5" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.nature.com/articles/s43247-025-02034-5</a>

anlomedadHm. <a href="https://www.nature.com/articles/s41467-021-23010-5" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.nature.com/articles/s41467-021-23010-5</a> "Timescales of the permafrost carbon cycle and legacy effects of temperature overshoot scenarios" by deVrese and Brovkin 2021They took one of the plant-soil models and looked in an overshoot scenario what the temperature rise and artificial sudden removal of atmospheric CO2 does to the soil and carbon store in the <a href="https://climatejustice.social/tags/Arctic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Arctic</a>. The end result after adaption to new stabilisation level is: carbon store is only 40GtC lower than before the overshoot, ie a mere 4 years worth of current global fossil CO2 emissions. This surprisingly (to me) low end result of -40GtC is due to increased plant growth from the temperature increase over pre-industrial, from the prolonged growth seasons, and a special Arctic circumstance of high Nitrogen availability that ensures nutrients for excessive plant growth.But the "end result" comprises the whole adjustment period to a stabilised °C after the overshoot. Adjustment takes 1000 yrs in the model. And in the interim periods, emissions from thawing permafrost do reach 1 to 1.5GtC each year, and for decades! The duration for this soil-atmosphere carbon flux depends on the level and duration of the temperature overshoot. Of course, it also increases the <a href="https://climatejustice.social/tags/CO2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CO2</a> amount to be artificially removed to undo an <a href="https://climatejustice.social/tags/overshoot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#overshoot</a>. In the context of <a href="https://climatejustice.social/tags/RCPcollapse" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RCPcollapse</a> : the toot above showed how natural CO2 removal after civilisation collapse leads to temperature reduction of more than 0.5°C within 30 years . Now, while permafrost thaw is irreversible on human time scales, it won't continue in RCPcollapse. (Because Arctic permafrost has no general technical tipping point after which self-perpetuating or self-reinforcing processes would kick in. Such processes only exist in small areas, locally, with local-only tipping behaviour. See "Global Tipping Points Report" 2023, chapter on <a href="https://climatejustice.social/tags/cryosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cryosphere</a> <a href="https://nora.nerc.ac.uk/id/eprint/536521/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://nora.nerc.ac.uk/id/eprint/536521/</a>) In RCPcollapse, the adjustment to the new equilibrium will take 1000 years – but there won't be a palpable increase in °C from the thaw.
