🌍💻 Networking week for our group! This week, members of our team represented our working group at two exciting international conferences — one focused on cutting-edge programming, the other on the icy frontiers of Antarctic research! 🧊 Christian and Gunnar attended the #SCAR2026 Open Science Conference in Oslo with great discussions about Antarctic science and policy! Especially, a lot of good input and ideas for the upcoming @AntarcticaInSync and IPY5 initiatives were presented. 💻 Marcus joined the JuliaCon 2026, diving into the vibrant community driving innovation in scientific computing with the Julia programming language. We're happy to see our team engaging with such diverse and impactful scientific communities — from the depths of Antarctic ice to the frontiers of computational tools! ❄️👩💻

Siberia's growing methane threat could offset 20% of global methane reduction targets by 2050
The #Arctic is warming at an accelerating pace. As #permafrost thaws across vast areas and wildfires become more frequent, large amounts of #methane (CH4) are being released. Together, these changes are reshaping the region's #GreenhouseGas emissions and further intensifying climate change.
In a study published in Science on August 6, an international team led by Professor Liu Yi from the Institute of Atmospheric Physics #IAP of the Chinese Academy of Sciences investigated how #CH4 #emissions in #Siberia are evolving under #ClimateChange. The study showed how atmospheric circulation promotes #wildfire activity and #methanogenesis and thereby drives the recent sharp rise in CH4 emissions.

Rock Weathering Can Counteract River CO2 Emissions Induced By Permafrost Thaw

“[The researchers] measured carbon emissions and water chemistry in 50 headwater rivers draining 780,000 km² of the Tibetan Plateau.
The rivers flow in landscapes underlain by continuous permafrost and landscapes in which the permafrost has retreated since the last glacial maximum. They collect[ed] organic carbon from soils and dissolved inorganic carbon that is fixed by rock-weathering.
Where the permafrost cover is continuous, rivers emit CO2 from degrading (permafrost) soil carbon. Weathering reactions in these catchments are relatively slow.
In landscapes with (almost) no permafrost, carbon fluxes from weathering are faster than CO2 emissions from rivers.
Thus, as permafrost landscapes transition to landscapes without permafrost cover, chemical weathering reactions may play an ever more important role in riverine carbon cycling.
Interestingly, weathering can affect the carbon cycle in different ways. Where sulfide minerals are present, weathering reactions can emit CO2. Where silicate minerals dominate, weathering draws down CO2 from the atmosphere…”

“Climate-induced permafrost thaw unlocks large stores of organic carbon that are mineralized and emitted as carbon dioxide (CO2) from rivers to the atmosphere. Concurrently, warming and permafrost thaw can increase mineral weathering rates, thus affecting the release and sequestration of inorganic carbon. Yet how these biological and geological carbon cycles interact and jointly affect CO2 dynamics (emission compared with drawdown) in permafrost rivers remains unknown. Here [they] combine[d] CO2 emissions, organic and inorganic solute concentrations, dual carbon isotopes (δ13C–Δ14C) and geochemical modelling to infer how permafrost thaw may affect river biogeochemistry over decades to centuries across the Qinghai–Tibet Plateau. Leveraging a gradient of thermal permafrost degradation, we find that river CO2 emissions decline, whereas solute fluxes from rock weathering increase with decreasing permafrost cover. Across this region, net CO2 drawdown fluxes from rock weathering are about 35% of river CO2 emissions, varying from around 15% in catchments with continuous permafrost to more than 100% in catchments with discontinuous or isolated permafrost. Thus, carbon fluxes from chemical weathering may become increasingly important with ongoing permafrost thaw, potentially even outpacing river CO2 emissions. [Their] findings disentangle the interplay between biological and geological carbon fluxes that are important for the cryosphere and the global carbon cycle…”

“Can we develop a first-order understanding of permafrost degradation and glacial lakes exposed to degradation-induced mass movements in the Himalaya?
[The authors] tried to address this question. The study [first link above] integrates machine learning, statistical modeling, and numerical modeling to investigate high-resolution permafrost distribution, potential degradation, and associated mass-movement hazards in the Kinnaur district of Himachal Pradesh, India.
Using rock glaciers as proxies, [they] generated a high-resolution permafrost distribution using machine learning, while potential degradation zones were delineated using the 0°C isotherm as a first-order indicator. [They] further identified glacial lakes located near potentially degrading permafrost zones and reconstructed their bathymetry. A detailed scenario-based GLOF process-chain simulation was then carried out for Kashang Lake using r.avaflow and HEC-RAS.
[Their] results indicate that seven glacial lakes in #Kinnaur are located close to potentially degrading permafrost zones. The simulations further show that a potential GLOF from Kashang Lake could inundate critical downstream infrastructure, including nearly 11 km of National Highway 5…”

“PLAIN LANGUAGE SUMMARY: On 3 July 2022, a portion of the Marmolada glacier, near Punta Rocca, collapsed and caused the death of 11 mountaineers. This dramatic event had a considerable impact on the media, and authorities were concerned about the risk that other collapses might occur in this and other glaciers of the Dolomites, a well-renowned mountain region of the southeastern Alps and one of the UNESCO World Heritage sites. [They] analyzed the possible causes of the collapse by developing a three-dimensional thermo-mechanical model. The analysis concluded that the collapse was caused by increased internal ice temperature and the development of a dense network of fractures, reducing the ice shear strength, with melting water that possibly contributed by increasing the basal pressure. [They] also showed that collapsing conditions can be identified with a simplified model version approximating the sliding basal surface as a plane with a slope equal to the surface slope. The developed approach can be used in hazard identification and risk analysis of mountain glaciers…”

Scientists say finding is ‘very concerning’ as collapse would be catastrophic for Europe, Africa and the Americas
"Prof Stefan Rahmstorf, at the Potsdam Institute for Climate Impact Research in Germany, said: “I now am increasingly worried that we may well pass that Amoc shutdown tipping point, where it becomes inevitable, in the middle of this century, which is quite close.” "
"Rahmstorf, who has studied the Amoc for 35 years, has said a collapse must be avoided “at all costs”. “I argued this when we thought the chance of an Amoc shutdown was maybe 5%, and even then we were saying that risk is too high, given the massive impacts. Now it looks like it’s more than 50%. The most dramatic and drastic climate changes we see in the last 100,000 years of Earth history have been when the Amoc switched to a different state.” " >>

I know you are all waiting for cheap oil, but
"Cutting the carbon dioxide pumped into the atmosphere by burning fossil fuels to zero is the only way to halt global heating. WWF is also calling for emperor penguins to be listed as a “specially protected species” at the next Antarctic treaty meeting in May in Japan, which would help reduce other pressures on their habitat such as tourism and shipping."
“Human-induced climate change poses the most significant threat. Early sea ice breakup is already affecting colonies around the Antarctic, and further changes in sea ice will continue to affect their breeding, feeding and moulting habitat. Emperor penguins are a sentinel species that tell us about our changing world and how well we are controlling greenhouse gas emissions that lead to climate change.” >>

State of the Global Climate 2025
The World Meteorological Organization "State of Climate report confirms
2015-2025 hottest 11 years on record
Earth’s energy imbalance is highest in sixty five-year record.
The ocean has been absorbing about eighteen times the annual human energy use each year for the past two decades.
Extreme weather impacts millions and costs billions."
