    “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…”

  4. A quotation from Ellis Peters

    You do what you must do, and pay for it. So in the end all things are simple.

I was so intrigued by the things she said that a few days later we ended up talking about ring theory over ramen.” - Aleksandra Brodowy

  7. HIPAA Fines Hit $1.7 Million for Risk Analysis Failures

    The consequences of neglecting HIPAA risk analysis are steep: four entities recently paid a total of $1.7 million in fines for failing to conduct accurate, timely, and thorough assessments, exposing sensitive health information of nearly 427,000 individuals to hacking and ransomware threats.

  8. The new handshake for analysis is a binary choice: Shape vs. Explicit.

    ​🔷 The Shape (Free): Surface-level telemetry for those with the expertise to interpret the diagnostic from the architecture alone.

    ​🔶 The Explicit (1 Token): Deep-stack data injection. No ambiguity. For those requiring the "Great Spear" of concurrency and definitive validation.

  10. 5 things that could break the tech growth thesis:

    1. AI bubble burst if ROI disappoints
    2. Power grid cannot keep pace (most likely)
    3. US-China chip war escalation
    4. Regulatory backlash against AI/data
    5. Sustained high interest rates

    I assessed probability for each. Number 2 is already happening in Northern Virginia, Dublin, and Singapore.

  12. Thousands of studies describe Rayleigh–Taylor instability, and most hydrogeological models acknowledge its importance in contaminant transport.

    However, in studies of the Svystunova gully mine-water storage pond, I have not seen density explicitly accounted for — despite highly mineralized waters where this factor can fundamentally change plume behaviour.
    By calculating solution density within the contamination halo, I demonstrated a real risk of gravity-driven sinking of the contamination plume to the base of the aquifer. This finding adds a critical dimension to impact assessment and is now documented as a standalone section in my ongoing report.

    If you work with mine water, aquifers contamination, or long-term contamination modelling, this is a parameter worth revisiting.

  17. 4/🧵3rd risk I’d add to my growing list of #2026predictions is around failed states, and the geopolitical, cultural and conflict disruptions they could easily cause. To wit, Iran and Pakistan are both hovering perilously close to the brink of state failure. Pakistan is nuclear-armed, and Iran is nuclear-ready (even after US and Israeli strikes). Both face seemingly unsolvable financial, energy, food and water crises currently unfolding; not to mention the threats both countries face from internal unrest driven by oppressed minorities seeking autonomy or statehood. in South America, several countries are perpetually on the brink of failure. Venezuela and Cuba come to mind. Likewise in #MENA and sub-Saharan Africa, states like Sudan and Yemen are currently collapsing. A few west African military dictatorships are also suspect. Failed states mean mass migrations, the spread of disease, the collapse of infrastructure and agriculture - resulting in regional disruptions and global risk. #NewYear2026 #RiskAnalysis

  19. 3/🧵2nd risk I see relates to a rapid acceleration of #GlobalWarming and the #ClimateCrisis - In this potential risk scenario, melting glaciers and polar ice sheets accelerate #SeaLevelRise while simultaneously creating flood then drought cycles in geographic regions that depend on glacier melt to annually replenish critical rivers and waterways. Ground water depletion (as is happening in Iran and the #MiddleEast in general right now) exacerbates the situation and prompts #WaterWars and mass migrations that strain regional borders and geopolitics. Parts of Africa, the Middle East, Asia and the American South become virtually uninhabitable due to heat-related issues. Agriculture fails and the global food supply is threatened. In another #Climate related risk scenario, the AMOC overturns - thrusting much of Europe into a mini ice-age, disrupting agriculture, industry and public health. #2026predictions #NewYear2026 #RiskAnalysis #GeoPolitics

  21. 2/🧵Now I’ll be presumptuous enough to add some looming *potential* risks and threats facing us in 2026 and beyond. These are my concerns…
    1. China’s deflation, driven my the ongoing property collapse and construction company defaults; high youth unemployment; unsustainable personal and local government debt; declining consumer consumption, and a demographic collapse will roil the country leading to unrest. The Chinese Communist Party and chairman Xi respond by invading Taiwan to distract the population and appeal to nationalism to restore unity. This brings the USA and Japan into the what will be called the war of the South China Sea. When the Russians enter the fray on the Chinese side, the conflict becomes WWIII and the Chinese break out their multi-warhead hypersonic nukes to bring an end to the conflict. This results in a global nuclear conflagration that sweeps the planet. #2026predictions #NewYear2026 #RiskAnalysis #War #China

  25. A quotation from Terry Pratchett

    And Sergeant Colon once again knew a secret about bravery. It was arguably a kind of enhanced cowardice — the knowledge that while death may await you if you advance it will be a picnic compared to the certain living hell that awaits should you retreat.

    Terry Pratchett (1948-2015) English author
    Discworld No. 21, Jingo (1988)

  33. "It is commonly stated that risk science is politically neutral. This perspective article discusses this assertion by scrutinizing the relationship between risk science and politics... Using some current risk problems as illustrating examples, including COVID-19 and climate change risk, the article argues that defending the political neutrality aim is paramount, especially with today's increasingly divisive political landscape."
