    TUHOKlimaticka zmena / Destroying the Future Is the Most Cost-Effective


    "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.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?

    Forget carbon neutral, Northwestern takes concrete NEGATIVE
    https://electrek.co/2025/03/25/forget-carbon-neutral-northwestern-develops-carbon-negative-concrete/

    We have developed a new approach that allows us to use seawater to create carbon-negative construction materials. Cement, concrete, paint, and plasters are customarily composed of or derived from calcium- and magnesium-based minerals, which are often sourced from aggregates –– what we call sand. Currently, sand is sourced through mining from mountains, riverbeds, coasts and the ocean floor. In collaboration with Cemex, we have devised an alternative approach to source sand — not by digging into the Earth but by harnessing electricity and CO2 to grow sand-like materials in seawater.

    🇦🇹 Co plánuje nová rakouská vláda v oblasti klimatu a energetiky?

    • Plánují pokrýt 100 % rostoucí domácí spotřeby elektřiny z obnovitelných zdrojů. (datum v dokumentu není)
    • Plánují nový klimatický zákon, který stanoví závazné roční emisní cíle a pravidelné pětileté revize, při nichž se vyhodnocuje dosažený pokrok a případně se upravují opatření s cílem dosáhnout klimatické neutrality do roku 2040.
    • Podpora rozšíření využívání zelených plynů, včetně biometanu a dalších obnovitelných plynů, na 6,5 TWh ročně do roku 2030.
    • Zavést regulační rámec pro postupný přechod od fosilního plynu ve vytápění budov směrem k nulovým emisím.
    • Připravuje se právní rámec pro vytvoření adekvátně dimenzované vodíkové sítě.
    • Rakouský model oceňování CO₂ bude převeden do schématu EU ETS 2. V EU ETS 1 se bude jednat s EU o úpravách proti carbon leakage, aby se zajistila spravedlivá konkurenceschopnost domácích podniků.
    • Vyvine se mechanismus pro řešení krizových situací v oblasti elektřiny, plynu a tepla na základě evropských právních norem, aby byly ceny dostupné i v náročných obdobích.
    • Program podporuje rozvoj baterií a zmiňujě např. využití protihlukových zdí pro instalaci fotovoltaiky.
    • Národní energetický a klimatický plán (NEKP) bude přepracován a implementace opatření bude dělána za účasti spolkových zemí.
    • Spolková vláda bere svou roli vzoru v otázkách ochrany klimatu vážně a proto rychle zavede klimaticky šetrnou správu ve své působnosti, využije veřejné zakázky jako účinný nástroj a zvažuje vytvoření prioritních oblastí (trhů) pro ekologicky udržitelné produkty a služby.

    Carbon-Negative Construction
    https://www.anthropocenemagazine.org/2022/01/carbon-negative-construction/

    Hemp’s rapid growth, dense canopy, and ability to grow in nutrient-poor soils make the plant more efficient than trees at sequestering carbon. In construction, hemp is combined with a lime-based binder to create hempcrete, a carbon-negative biocomposite that can sequester over 100 kilograms of CO2 per square meter.

    “Hempcrete’s not only healthy and nontoxic, but is also resistant to fire, pests, mold, and mildew,” says Drew Oberholtzer, cofounder of Coexist Build, an architecture studio with a regenerative organic farm that doubles as a research and development lab for hemp-based building materials. The sustainable building material also boasts benefits for indoor air quality and, as its name implies, can be precast in blocks. This eliminates the time needed for curing on site and makes it easy to incorporate it into existing construction trades.

    Although hempcrete can be cast like concrete, it isn’t a substitute. The lightweight material lacks the structural integrity needed for load-bearing. It can, however, be used in place of traditional drywall, insulation, and siding—where its high thermal mass offers energy-saving benefits by reducing the need for heating and cooling.

    https://www.smithsonianmag.com/science-nature/what-happens-to-a-tree-that-dies-in-a-forest-180986121/

    Rotting logs turn out to be vital to forest biodiversity and recycling organic matter
    ...
    Dormant fungi within the tree awaken to feast on it, joined by others that creep up from the soil. Bacteria pitch in, some sliding along strands of fungi to get deeper into the log. Termites alert their colony mates, which gather en masse to gobble up wood. Bit by bit, deadwood is decomposed, feeding new life along the way.
    ...
    Wood-gobbling life forms, in turn, nourish other living things. Many beetle species munch on the spores, mycelia or mushrooms of wood-decaying fungi, while some ants specialize in hunting and eating termites. Estimates suggest that one third of insect species in a forest rely on deadwood in some way—and these insects are food for other invertebrates, as well as birds and bats. Rotting logs create excellent spots for tree seedlings to grow, and for animal nests, dens and burrows.

    “It’s pretty clear,” Seibold says, “that this is a habitat type and resource that we need to maintain this part of life on Earth.”
    ...
    As a log disappears, where does the wood ultimately go? Wood-eaters use some of the carbon for energy, expelling carbon dioxide—and farting methane, in the case of termites—as a waste product. Carbon also goes into building bodies; some termites use their lignin-rich feces to build nests and mounds. When these structures decay, some of the carbon is released into the air, while a portion stays on the ground, alongside leftover wood bits. Collectively, these leftovers become part of the humus of the soil, helping retain water and support soil-dwelling microbes, invertebrates and roots.
    ...
    Earth system scientist Steven Allison of the University of California, Irvine, reckons that while most of deadwood’s carbon ends up in the air, some stays locked in the soil for more than a century. “Deadwood is really your friend,” he says. “You want more of it, and you want it to stick around longer.”

    Massive methane leaks detected in Antarctica, posing potential risks for global warming | Climate | EL PAÍS English
    https://english.elpais.com/climate/2025-02-12/massive-methane-leaks-detected-in-antarctica-posing-potential-risks-for-global-warming.html

    Scientists have found enormous columns of methane gas leaking into the atmosphere from Antarctica, with the potential for further leaks amounting to the sum total of what humanity emits over two years.

    ...

    A team of Spanish scientists exploring the Antarctic seabed has detected “massive emissions” of methane, a gas with a capacity to warm the planet around 30 times greater than carbon dioxide (CO₂). The researchers, on board the ship Sarmiento de Gamboa, have observed columns of methane in the ocean up to 700 meters long and 70 meters wide, according to the geologists Ricardo León and Roger Urgeles, leaders of the expedition, in statements to EL PAÍS. These previously unknown emissions could potentially represent an environmental bomb for the planet’s climate.

    The EU should cut its emissions to 90% below 1990 levels by 2040, according to a new roadmap released by the European Commission.

    This will require an expanded and emissions-free power system within 16 years and an 80% reduction in the use of fossil fuels for energy, the new guidance states.

    The goal is designed to bridge the gap between bloc’s existing short- and long-term emissions reduction targets.

    2024 Ruminating on soil carbon: Applying current understanding to inform grazing management
    https://onlinelibrary.wiley.com/doi/10.1111/gcb.17223

    Among options for atmospheric CO2 removal, sequestering soil organic carbon (SOC) via improved grazing management is a rare opportunity because it is scalable across millions of globally grazed acres, low cost, and has high technical potential. Decades of scientific research on grazing and SOC has failed to form a cohesive understanding of how grazing management affects SOC stocks and their distribution between particulate (POM) and mineral-associated organic matter (MAOM)—characterized by different formation and stabilization pathways—across different climatic contexts. As we increasingly look to grazing management for SOC sequestration on grazinglands to bolster our climate change mitigation efforts, we need a clear and collective understanding of grazing management's impact on pathways of SOC change to inform on-the-ground management decisions. We set out to review the effects of grazing management on SOC through a unified plant ecophysiology and soil biogeochemistry conceptual framework, where elements such as productivity, input quality, soil mineral capacity, and climate variables such as aridity co-govern SOC accumulation and distribution into POM and MAOM. To maximize applicability to grazingland managers, we discuss how common management levers that drive overall grazing pattern, including timing, intensity, duration, and frequency can be used to optimize mechanistic pathways of SOC sequestration. We discuss important research needs and measurement challenges, and highlight how our conceptual framework can inform more robust research with greater applicability for maximizing the use of grazing management to sequester SOC.

    While floating solar – the emerging practice of putting solar panels on bodies of water – is promising in its efficiency and its potential to spare agricultural and conservation lands, a new experiment finds environmental trade-offs.

    “There have been a flurry of papers about floating solar, but it’s mostly modeling and projections,” said Steven Grodsky, assistant professor of natural resources and the environment and assistant unit leader of the New York Cooperative Fish and Wildlife Research Unit in the College of Agriculture and Life Sciences at Cornell University, as well as a faculty fellow at the Cornell Atkinson Center for Sustainability. “This is the first manipulative study to produce empirical results. It’s saying, here’s what’s actually happening. And what we found was that there was increased greenhouse gas emissions from ponds with floating solar.”

    Grodsky and collaborators covered three ponds at the Cornell Experimental Pond Facility with solar panels, at 70% coverage, and found that, almost immediately, methane and carbon dioxide emissions increased – by 26.8% compared to ponds without solar panels – and dissolved oxygen throughout the ponds substantially decreased.

    Climate change target of 2C is ‘dead’, says renowned climate scientist | Climate crisis | The Guardian
    https://www.theguardian.com/environment/2025/feb/04/climate-change-target-of-2c-is-dead-says-renowned-climate-scientist

    “The Intergovernmental Panel on Climate Change (IPPC) defined a scenario which gives a 50% chance to keep warming under 2C – that scenario is now impossible,” he said. “The 2C target is dead, because the global energy use is rising, and it will continue to rise.” The new analysis said global heating is likely to reach 2C by 2045, unless solar geoengineering is deployed.

    ...

    A key focus has been on emissions from shipping. For decades, the sulphate particles produced by ships burning fuel have blocked some sunlight from reaching the Earth’s surface, suppressing temperatures. But in 2020, new anti-pollution regulations came into force, sharply cutting the level of the aerosol particles. This led to more heat from the sun reaching the surface, which scientists measure as watts a square meter (W/m2).

    Hansen’s team’s estimate of the impact of this – 0.5W/m2 – is significantly higher than five other recent studies, which ranged from 0.07 to 0.15 W/m2, but would explain the anomalous heat. Hansen’s team used a top-down approach, looking at the change in the reflectivity over key parts of the ocean and ascribing that to the reductions in shipping emissions. The other studies used bottom-up approaches to estimate the increase in heat.

    “Both approaches are useful and often complementary,” said Dr Gavin Schmidt, director of Nasa’s Goddard Institute for Space Studies. “But I think in this case, Hansen’s approach is too simple and doesn’t factor in changes in Chinese emissions, or internal variability.”

    The new study also argues that the planet’s climate sensitivity to rising carbon emissions has been underestimated, partly because of the underestimation of the impact of reduced shipping emissions.

    Catastrophic tipping point in Greenland reached as crystal blue lakes turn brown, belch out carbon dioxide | Live Science
    https://www.livescience.com/planet-earth/climate-change/catastrophic-tipping-point-in-greenland-reached-as-crystal-blue-lakes-turn-brown-belch-out-carbon-dioxide

    Record heat and rain turned thousands of Greenland lakes brown in 2022 as they hit a tipping point and began emitting carbon dioxide.
    ...
    Less sunlight was able to penetrate the lakes as they darkened, which had a ripple effect on the microscopic plankton living in the water. The number of plankton absorbing CO₂ through photosynthesis — the process of turning sunlight into energy — declined, while the amount of plankton breaking down and releasing carbon increased, according to a statement released by the University of Maine.

    The lakes normally absorb CO₂ in the summer, but by the following year they had flipped to become carbon dioxide producers. These types of widespread changes would normally take centuries. Researchers have observed the browning of lakes across the Northern Hemisphere, including the U.S., but it typically takes multiple decades — much longer than the transformation of Greenland's lakes.

    🇪🇺 European Commission dnes představila očekávaný Kompas konkurenceschopnosti, ve kterém v návaznosti na Draghiho zprávu nastiňuje, jak chce zvýšit konkurenceschopnost unijních podniků.

    Celé je to hodně o zjednodušování (povolovacích procesů, státní podpory, reportingu), inovacích, zvyšování soběstačnosti a odolnosti.

    💡 Důležité je pro mě opakované potvrzení, že cíle Zelené dohody a klimatické neutrality v roce 2050 zůstávají a že Komise stojí za emisním cílem −90 % pro rok 2040. Stejně tak zůstávají stejné emisní cíle pro automobilový průmysl (ač s explicitní zmínkou technologické neutrality a e-paliv).

    Jsem zvědavá na konkrétnější vykreslení dekarbonizačních opatření, které na konci února přinese Clean Industrial Deal.

    V samotném Kompasu mě ještě mj. zaujalo, že Komise navrhne vznik 28. právního režimu, ve kterém by pro inovativní podniky odpadaly starosti s 27 různými regulačními prostředími.

    Co v Kompasu zaujalo vás?

    ---
    Kompas obsahuje i časový rámec pro jednotlivé iniciativy, např.:

    – Clean Industrial Deal and an Action Plan on Affordable Energy [Q1 2025]
    – Amendment of the Climate Law [2025]
    – Industrial Decarbonisation Accelerator Act [Q4 2025]

    China's solar, wind power installations soared to record in 2024
    https://www.reuters.com/business/energy/chinas-solar-wind-power-installed-capacity-soars-2024-2025-01-21/

    China broke its own records for new wind and solar power installations again last year, official data showed on Tuesday, accelerating from a breakneck pace set in 2023 as the country looks to peak its carbon emissions before 2030.

    Installed solar and wind power capacity climbed 45.2% and 18%, respectively, in 2024, the National Energy Administration said on Tuesday.

    There is now 886.67 GW of installed solar power, up from 609.49 GW in 2023, it said. The United States had 139 GW in 2023, according to the International Renewable Energy Agency

    The installations mean China in July hit its 2030 target six years ahead of schedule, underscoring the speed of its clean energy rollout at a time when President Donald Trump has pulled the United States out of the Paris climate deal for a second time and pledged to make it easier to drill for oil and gas.

    By 2030, solar power capacity should meaningfully outstrip coal, which still dominates China's grid, at 1,780 GW to 1,440 GW, state-owned oil major China National Petroleum Company said at a separate briefing.

    Last in August, China's state planner unveiled a three-year plan to upgrade the power system, increasing its use of renewable energy and easing the strain of rising power demand on the national grid.

    z obecnejsi duskuze o politice asset managementu


    There was a phenomenon where in the five or six years after the Paris climate agreement, which was in 2015-2016, there was significant hope amongst large parts of the population and the professional classes that governments were getting serious about climate. The belief was that they were going to take measures, whether that's significant carbon taxes or whatever else it might be, that would really entail a shift away from fossil fuel capitalism.

    I think that what's happened over the last three or four years in particular is that the realization has kind of dawned—and people don't want to say it explicitly, but I think people are sort of implicitly seeing it—that it's not happening and that the governments are actually not serious about taking the types of actions that are necessary to keep temperatures at two degrees, two and a half degrees. You know, forget 1.5 degrees—governments aren't serious about keeping temperatures to two and a half degrees. I mean, of course they're not going to say that, but no, I don't think they're remotely serious about it.

    I was in Norway recently, and in May 2021, the International Energy Agency came out with this really, I think, incredibly significant report which they called "Net Zero by 2050." They basically said, look, for the energy sector, which is obviously the very heart of the climate problem, to be able to be net zero—not actual zero, net zero—by 2050, this is the kind of path it has to take over the next 29 years, whatever it was (it was 2021, so the next 21 years). And basically, for that to be possible, there can be no new approvals of oil and gas field developments and no new approvals of coal mines anywhere in the world from this day forward—none, zero—to have any chance of hitting net zero by 2050.

    And so, as I said, I was in Norway a few weeks ago. Over 160 approvals of new oil and gas field development licenses have been approved just in Norway since May 2021. So no, the governments aren't remotely serious. Oil and gas field development licenses have been showered like confetti around the world since then, and so I think the investment world looks at what governments are doing and they say, "Governments, which have to be the ones that take the lead, are not serious about this, so why should we be serious about this? If governments are not taking the types of actions that will make fossil fuel investments less profitable and green capitalism much more profitable, why would we bother with ESG?"

    Here is James Hansen's great piece on the natural science of the elite's emission of carbon, and not great piece on the social science of the elite's emission of carbon.

    Let's start with social science law number one. Power resides in sovereign states, not global courts. Even if global courts say that what the elites are doing is illegal, nothing will change.

    Social science law number two. States only fundamentally change - change their regimes - when there is material resistance from their populations - national strikes and mass occupations of the streets for several weeks or months. The only effective way to create structural political change in the time we have left is through this civil resistance - in comparison with alternative ineffective methods (voting, lobbying, legal challenge).

    This is a historical no brainer. It has happened hundreds of times over the past two hundred years - most recently in Bangladesh. The primary reason why it is not happening is because of the scientifically illiterate and irrational attachment of the Western liberal and administrative classes to means of change which simply do not work - have not worked for 30 years - and will not work in the future. Because entrenched power does not respond to such methods. Only when the young realise they are being duped by those who continually mislead them, will they do what they always do to create regime change - go on the streets and stay there.

    I have been saying this for 10 years now. Not because I have a particular ideological attachment to civil resistance or public disruption any more than those that report of climate breakdown want ecological collapse to happen. It is simply about what is real.

    Social science law number three is that the liberal class never moves in time. And that is why you end up having full blown revolutions. But of course no one wants to talk about that. Not yet. But it will come, as surely as an apple dropping to the ground. It's Newtonian determinism.
