    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."


    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    TADEAS: Jeste jsem necetl, nicmene odkladam si na tema

    Long before the current AI power panic, there was another panic about a new technology with an insatiable thirst for electricity: the internet.

    In 1999, Peter Huber and Mark Mills wrote an article for Forbes Magazine titled “Dig more coal -- the PCs are coming.” Reading that story today is eery in its similarities to the current moment. In the opening paragraph, the authors write, “Somewhere in America, a lump of coal is burned every time a book is ordered on-line.” They go on to cite statistics about the staggering growth of the internet: “Traffic on the Web has indeed been doubling every three months.” And then they make a prediction: “It’s now reasonable to project that half of the electric grid will be powering the digital-Internet economy within the next decade.”

    Huber and Mills were, of course, right in their prediction about the ubiquity and importance of the internet. The technology changed nearly everything about our society, economy, and politics. They were correct in predicting that internet traffic, adoption, and infrastructure would explode. And yet, their forecast for how much electricity demand would ensue was fantastically wrong.

    > For many regions, this refinement yields predictions that are weighted towards the early part of the CMIP6 distribution, with transfer learning generally shifting the prediction earlier than without transfer learning. These results suggest a very high likelihood of 2.0 °C of regional warming by 2040 for the majority of regions, along with a likelihood of 3 °C by mid-century.

    The natural phenomenon is part of a recurring ocean-and-atmosphere pattern that warms and cools the eastern tropical Pacific through El Niño and La Niña events that last from one to three years. El Niño conditions usually lead to below-average hurricane seasons because of an increase in wind shear, which can disrupt the structure of tropical cyclones.
    On the other hand, the oceans were already record-warm. And warm sea surface temperatures tend to lead to above-average hurricane activity.

    “The Atlantic basin produced the most named storms of any El Nino influenced year in the modern record,” said Matthew Rosencrans, lead hurricane forecaster at NOAA’s Climate Prediction Center — a division of NOAA’s National Weather Service. “The record-warm ocean temperatures in the Atlantic provided a strong counterbalance to the traditional El Nino impacts.”

    Minsky moment: are pension assets at risk due to flawed climate analysis? | Netzeroinvestor
    https://www.netzeroinvestor.net/news-and-views/are-millions-of-pensions-at-risk-due-to-flawed-climate-analysis

    Widespread reliance on flawed research generates a disconnect between current investment decision making, which assumes relatively trivial impacts from climate change, and the likely real-world effects of global warming, Keen warned.

    "To ensure that the world moves into a new climate secure energy system, it’s crucial pension schemes send the market the right investment signals,” said Mark Campanale, the founder of Carbon Tracker.

    “The signal has to be that a swift, orderly transition is in everyone’s financial interests, particularly for scheme beneficiaries.”

    However, the relationship between economics, climate science and assessing financial risk is not a “comfortable one,” he continued, adding that “the advice pension schemes are receiving risks trivialising the potentially huge damage climate change will have to asset values."

    Campanale stressed that “these flawed climate risk models” are used throughout the financial system, lulling economic decision makers, from pension funds to central banks, into a false sense of security.

    “The result is cavalier positions such as US Federal Reserve Board Governor Christopher Waller who announced: ‘Climate change is real, but I do not believe it poses a serious risk to the safety and soundness of large banks or the financial stability of the United States’,” he said.

    The report issues a direct warning to asset owners for the serious prospect of an “unpleasant, abrupt and wealth destroying” so-called “Climate Minsky moment” with a sudden collapse in asset values as financial markets wake up to the gap between mainstream economist forecasts and the reality of climate impacts.

    Keen, who is also the former head of the School of Economics, History and Politics at Kingston University, London, contrasts scientists’ empirical research with predictions by climate economists that are “a ‘hunch’ based on rather spurious assumptions for global warming, which have been used to generate equally spurious estimates of damages to future GDP.”

    He underscored that global warming, at less than 1.5°C, is already affecting people and companies across the planet, pointing at record heatwaves, floods, and intensifying storms as they halt commerce, damage crops, create uninsurable areas, and impair infrastructure.

    Keen singled out scientific research which finds that exceeding the 1.5°C Paris target would be “dangerous”, passing 3°C would be “catastrophic”, and reaching 5°C will be “beyond catastrophic, raising existential threats”.

    Yet, despite scientific predictions, a survey of 738 climate economics papers in a number of top academic journals found the median prediction of economists was that 3°C of warming would reduce global GDP by just 5%, and warming of 5°C would see a 10% reduction.

    ...

    The researchers singled out investment managers and consultants such as Aon Hewitt, Hymans Robertson and Mercer as they "continue to rely on flawed research" when they advise pension funds on the impacts of global warming on members’ portfolios.

    For example, Mercer, in advice to Australian fund HESTA predicts only a -17% portfolio impact by 2100 in a 4°C scenario. It states that its model primarily reflects coastal flood damage and does not take account of climate tipping points.

    Mercer also advises LGPS Central, which manages £28.5 billion of retirement savings for a million members of Local Government Pension Schemes in the UK.

    One of these schemes, Shropshire County Pension Fund, told members that a trajectory leading to 4°C by 2100 would only reduce annual returns by 0.06% in 2030 and 0.1% by 2050, saying that it relied on LGPS Central for information.

    Moreover, in a 2022 report, Australian superannuation firm Unisuper concluded that even in a “worst case scenario” involving a 4.3°C increase in global temperatures by 2100, “the overall risk to our portfolio is acceptable.”

    “Each layer in the process of assessing the risks of climate change has assumed that the previous layer has done its job adequately, and has relied on the previous layers reputation, rather than scrutiny of the work undertaken," explained Professor Keen.

    “Pension funds rely upon consultants because of their reputation in the field; consultants rely upon academic economists, because their papers had passed academic refereeing,” he added.

    “The final impact is a series of flawed economic assumptions informing pensions’ decision making.”

    1. The collapse of the Atlantic Ocean circulation (AMOC) will be the most devastating event in the last 10,000 years of human history.
    2. It will happen overnight with sudden effects.
    3. It will be irreversible and continue for 1000s of years.
    4. It will destroy human civilisation because it will be impossible to grow food in northern Europe - temperatures would drop by 3.4°C. Enough to half the amount of land where you can grow wheat.
    5. 100s of millions of Europeans will have to move or starve to death. Those that move will be subject to holocaust events created by warlords and/or fascistic regimes.
    6. Coastal cities will have to be evacuated
    7. Monsoons in the tropics will collapse, resulting in 100s of millions more refugees.

    This is just the beginning - the collapse also will feed into other disastrous climate tipping points like the collapse of the Amazon rainforest. We are looking at billions of deaths and possible effective extinction this century - that now has to be the main concern.

    Last but not least, the above scenario is a conservative prediction because it doesn't take into account the non-linear effects of other systems on the AMOC collapse date (e.g the collapse of ice cover in the Arctic, methane release, and mega forest fires).

    Why is no one talking about this?
    Why aren't there emergency conferences of Europe's farmers?
    Why aren't the media going on strike till the government acts?
    Why aren't there mass sit-downs in cities for weeks on end?

    Because repressed scientists just say that it's "kind of scary" - like saying Auschwitz was "kinda of unpleasant".

    The situation is totally fucked.

    In August 2021, UNICEF warned that over one billion children are at extreme risk of the impacts of AGW [161]. According to the Children’s Climate Risk Index (CCRI) [161],
    240 million children are exposed to coastal flooding;
    330 million to riverine flooding;
    400 million to cyclones;
    600 million to vector borne diseases;
    815 million to lead pollution;
    820 million to heatwaves;
    920 million to water scarcity and
    one billion children to dangerously high levels of air pollution.
    Looking at the problem from different perspectives provides convergent evidence for an estimate of 1 billion deaths at 2 °C of warming:
    The estimate corresponds to 10% of the projected future world population. All 10 billion humans will need food and fresh water to survive, and AGW will seriously affect both.
    Since CO2 stays in the atmosphere for about a century, the prediction implies that, on average, 10 million additional deaths per year will be due to AGW.
    If the wet-bulb temperature exceeds skin temperature, perspiration can no longer cool the body. Already in 2022, this effect was life-threatening for a billion people in India and Pakistan [162]. In the same countries in 2023, maximum temperatures were consistently above 40 °C for over two weeks [161].

    TUHO: Abstract—In this paper, we present Pangu-Weather, a deep learning based system for fast and accurate global weather forecast. For this purpose, we establish a data-driven environment by downloading 43 years of hourly global weather data from the 5th generation of ECMWF reanalysis (ERA5) data and train a few deep neural networks with about 256 million parameters in total. The spatial resolution of forecast is 0.25◦ × 0.25◦, comparable to the ECMWF Integrated Forecast Systems (IFS). More importantly, for the first time, an AI-based method outperforms state-of-the-art numerical weather prediction (NWP) methods in terms of accuracy (latitude-weighted RMSE and ACC) of all factors (e.g., geopotential, specific humidity, wind speed, temperature, etc.) and in all time ranges (from one hour to one week). There are two key strategies to improve the prediction accuracy: (i) designing a 3D Earth Specific Transformer (3DEST) architecture that formulates the height (pressure level) information into cubic data, and (ii) applying a hierarchical temporal aggregation algorithm to alleviate cumulative forecast errors. In deterministic forecast, Pangu-Weather shows great advantages for short to medium-range forecast (i.e., forecast time ranges from one hour to one week). Pangu-Weather supports a wide range of downstream forecast scenarios, including extreme weather forecast (e.g., tropical cyclone tracking) and large-member ensemble forecast in real-time. Pangu-Weather not only ends the debate on whether AI-based methods can surpass conventional NWP methods, but also reveals novel directions for improving deep learning weather forecast systems.e

    Global Warming in the Pipeline
    https://youtu.be/v-ArA_xYxfs


    Dr. Peter Carter, Paul Beckwith and Regina Valdez discuss a recent paper called ‘Global Warming in the Pipeline’ by James Hansen et al. The paper explains global warming will likely pierce the 1.5°C ceiling in the 2020s and 2°C before 2050 under the current geopolitical approach to dealing with anthropogenic greenhouse gas emissions.

    This video was recorded on May 24th, 2023, and published on June 18th, 2023.

    Some of the topics discussed:
    - How one of the key characteristics of climate change known for decades has always been inertia and momentum. This paper shows that at the current levels of greenhouse gases in the atmosphere, the planet is slowly moving towards a 10°C rise in global average temperature.
    - How James Hansen is a voice crying in the climate wilderness as he always seems to have been because the scientific community is not agreeing with him.
    - How one of the big feedbacks in the climate system is ice sheet albedo and its key role in leading us to a 10°C rise.
    - How the methane emissions feedback from the warming of the wetlands will be inevitable.
    - How a new draft of the paper was released on May 19th.
    - How the Global Climate Models (GCMs) have been under predicting the global average temperature rates of change and how by using the Equilibrium Climate Sensitivity (ECS), which is how much the climate warms for a doubling of CO2 levels, we can arrive at much more accurate prediction of global average temperature rise from paleoclimate data.
    - The enormity of consequences of climate change demands a return to a Holocene-level global temperature with the required actions that include: 1) A global increasing price on GHG emissions; 2) An East-West cooperation in a way that accommodates developing world needs; 3) Intervention with Earth’s radiation imbalance to phase down today’s massive human-made “geo-transformation” of Earth’s climate.
    - and much more. . .

    How many models do we have for prediction of global temperature?
    There are 2179 model intercomparisons used for AR6, 2098 models used for simulations, and 151,223 models for regional simulations. However, it is important to note that the fitness-for-purpose of the climate models used for long-term projections is fundamentally difficult to ascertain and remains an epistemological challenge.

    The system (objective1) will combine initialised climate predictions on the multi-annual timescale with longer-term climate projections and high resolution regional downscaling, using observations for evaluation. Methodologies will be developed to characterise uncertainty and to seamlessly blend the predictions and projections. Users will be engaged through active user groups. The system will be utilised (objective2) with users to co-produce information suitable for European climate service activities. A set of demonstrators will show the value of this information in real-world applications with user involvement (objective3). Key outputs will include disseminating and publishing the project’s methodologies, and user-relevant data and knowledge (objective4).

    Mame vyroci.

    Today marks the 50th anniversary of a remarkable research paper on global warming.
    Written by meteorologist John Sawyer, the paper – entitled “Man-made carbon dioxide and the greenhouse effect” – was published by the journal Nature in 1972.
    The paper discussed some of the key concepts involved in human-caused global warming and makes one of the first predictions of future global warming – that temperatures would rise 0.6C by the end of the 20th century.
    Sawyer’s calculations turned out to be only a slight overestimate of how the world would warm in the decades after his paper was published.
    His paper noted that “in spite of the enormous mass of the atmosphere and the very large energies involved in the weather systems which produce our climate”, the impact of human activity was “approaching a scale at which they cannot be completely ignored as possible contributors to climate and climatic change”.

    Thirty years ago modelers created a "business-as-usual" scenario, known as IS92a, to help understand the potential future of carbon dioxide in the atmosphere.

    Relative to that prediction, all of our collective efforts have only slightly slowed the accumulation of carbon dioxide.

    The trajectory that is most often assumed as a baseline these days is that carbon dioxide will continue to rise during the next several decades before stabilizing near the end of the century (as emissions are brought down).

    This leads to ~2.7 °C of warming in 2100.

    Speaking on the 43C prediction, Steven said the American GFS model has been suggesting some, "really high temperatures." He explained: "That signal is still there, with some really exceptionally unprecedented heat being signalled by this particular model, affecting particular parts of eastern and southern England next weekend, perhaps into the early part of next week."

    The European model has a similar reading which makes the prediction more reliable, though Steven stressed the forecast will be subject to change over the next few days

    One of the truly thrilling papers I’ve read in recent years carried the plodding title “Empirically Grounded Technology Forecasts and the Energy Transition.” The authors looked at more than 2,900 forecasts for how fast the cost of installing solar power would fall from 2010 to 2020. The average prediction was 2.6 percent annually. No prediction was above 6 percent. But solar power costs actually fell by 15 percent per year. Other technologies have seen similar drops in costs. If these curves hold in the future — and they could well steepen if backed by better policy — then we are, even now, underestimating the possible path of progress.
