    "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 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."

    Gaspard Koenig, philosopher: "The ecological transformation of our imagination is underway, and it is irreversible."
    https://archive.is/fapp1

    Today, the concepts of habitability, rewilding, and coexistence with non-human living beings are gaining ground. As anthropologist Philippe Descola puts it, "We have won." All avant-garde movements, whether scientific, literary, or activist, are moving in this direction. The 20th century is taking its time to die. Its agony is unbearable and convulsive, but it is doomed.

    The agroecological transition is key. Agricultural land currently covers half of France's surface area and a third of the Earth's land surface. While we can always add greenery to cities, the majority of the decline in biodiversity, and conversely, the potential for regeneration, stems from our fields and countryside.

    We must therefore rethink our relationship with humus. We must lower our gaze from the sky to the earth. Living soil is a reservoir of biodiversity, a sponge for water, a carbon sink, a diverse landscape, and even a healthy microbiota. Visually, it also means moving away from a monochrome and orthonormal aesthetic (yellow wheat, blue sky, straight lines) to appreciate a more anarchic beauty, that of spontaneous order. Finally, philosophically, it is a way to allow different species, including our own, to coexist. This is why our century must be physiocratic: the true source of wealth is the earth. By reinventing agriculture, we will simultaneously rethink society.

    It's too simplistic to think that abolishing capitalism would solve all our problems. Extractive industries predate and far surpass our current neoliberal madness. The Romans polluted their environment with lead, medieval peasants cleared land in unsustainable ways, and Soviet regimes were among the least respectful of nature. Our tendency to overexploit our environment is inherent in our humanity, even in our animal nature. As biologist Marc-André Selosse explains, deer grazing on young shoots or macaques gorging themselves on shellfish are simply responding to the dictates of natural evolution: short-term self-interest.
    We must therefore decouple the ecological question from that of the economic system. We are seeing the emergence of a kind of ecological socialism in China. We, for our part, can invent a liberalism constrained by planetary limits, as John Stuart Mill [1806-1873] already envisioned in the mid-19th century .

    Rather than relying on the goodwill of large corporations through corporate social responsibility, policymakers must establish rules or fiscal mechanisms that force the market to remain static. The circular economy and regenerative agriculture are good examples. It is perfectly possible to conceive of market exchanges without growth, by respecting a golden rule: only do what you know how to undo. Rather than vainly dreaming of transforming human nature, it is better to establish a system of incentives that harness its worst vices for the common good.

    I remain committed to defending the ideal of a society that is free, open, and ecological. First and foremost, there is one heartening certainty: life will emerge victorious from all climate and ecological crises. In a few million years—a mere trifle on the scale of natural evolution—ecosystems will have regenerated, and our mistakes will be forgiven.
    In the shorter term, we can clearly see the titanic struggle unfolding between two visions: that of artificial intelligence and that of living organisms. It is up to us to prove that the ecological project is not only more sustainable, but also more desirable. However, let's not fight the wrong battle. It is only when public opinion has shifted that political parties will finally take the environment seriously. The various doctrines can then be rebuilt on this foundation.

    The Financial Times first reported it, citing people briefed on the talks. Reuters, WSJ, and Bloomberg have independently confirmed via sources familiar with the matter.

    It's a consortium (Apollo, Blackstone, BlackRock GIP, Brookfield, Goldman, KKR) working with Nvidia to assemble a ~$500B funding package for AI infrastructure build-out (chips, power, data centers). Not a simple direct $500B loan to Nvidia. No official company statements yet; deal could be announced soon.

    Zachránili jsme ozonovou vrstvu. Náhradní chladiva ale přinesla problém věčné kyseliny – National Geographic
    https://www.nationalgeographic.cz/veda/nahradni-chladiva-freony-kyselina-tfa-znecisteni/

    Látky poškozující ozonovou vrstvu, zejména freony, začal svět po Montrealském protokolu postupně vyřazovat. Jejich náhrady – hlavně některá fluorovaná chladiva a také vybrané anestetické plyny – se v atmosféře mění na látku, která se v prostředí prakticky nerozkládá. Nová studie odhaduje, že mezi lety 2000 a 2022 se jí z těchto zdrojů na zemský povrch uložilo přes 335 000 tun.

    Od arktických ledovců po lidskou krev: kyselina trifluoroctová je přítomna všude na Zemi. Vědci z Lancasteru nyní ukazují, že významnou část globální depozice TFA – a patrně hlavní část jejího nárůstu v Arktidě – lze vysvětlit rozkladem náhrad freonů (CFC) a některých anestetik.

    Každý rok dopadá na povrch Země déšť, který nezanechává viditelné stopy. Přichází s obyčejnou srážkovou vodou, usazuje se v oceánech, prosakuje do půdy, mizí v arktickém ledu. Vědci tomuto procesu říkají depozice – látka „vypadne“ z atmosféry a usadí se v prostředí. Jednou uložená v prostředí se v běžných přírodních podmínkách prakticky nerozkládá a může se dlouhodobě hromadit zejména ve vodním prostředí. Kyselina trifluoroctová (TFA) patří mezi tzv. věčné chemikálie: látky tak chemicky stabilní, že v přírodě prakticky neexistuje mechanismus schopný jejich molekuly rozložit. Hromadí se rok od roku, bez úniku. A podle nové studie publikované v časopise Geophysical Research Letters je za její globální šíření z velké části odpovědné něco nečekaného – chladiva, která měla zachránit ozonovou vrstvu.

    ...

    Evropská agentura pro chemické látky TFA označuje za škodlivou pro vodní organismy – podobně jako jiné PFAS může narušovat ekosystémy jezer a řek. Německé úřady v roce 2025 navrhly harmonizovanou klasifikaci TFA jako látky toxické pro reprodukci, kategorie 1B. Německé úřady zároveň upozorňují, že klasifikace popisuje nebezpečnou vlastnost látky, nikoli sama o sobě skutečné riziko při konkrétní úrovni expozice. Právě proto je klíčové dlouhodobé sledování koncentrací TFA ve vodě, potravinách a biologických vzorcích. TFA byla detekována v lidské krvi i moči. Co to znamená pro zdraví? Vědci varují: TFA se hromadí rok od roku, a naměřené množství v prostředí nemusí být bezpečné navždy.

    Dr. Stefan Reimann, jehož výzkumný tým ve Švýcarsku soustavně sleduje atmosférické koncentrace F-plynů produkujících TFA, potvrdil, že jde o globálně konzistentní obraz: „Ve všech regionech, kde jsou k dispozici měření TFA, se rýsuje shodný obraz rostoucích atmosférických koncentrací a depozice na zemský povrch. Tato studie je výjimečná tím, že poprvé kombinuje všechny důležité zdroje atmosférické TFA v globálním měřítku. S rostoucím využíváním HFO bude akumulace TFA ve vodních útvarech potenciálně narůstat, a bez dlouhodobého sledování prostě nevíme, kam míříme."

    “We find that, since 2003, the decrease of cloudiness has been responsible for half of the increase of Earth’s energy imbalance. Analysing the drivers of global changes to cloud cover, we find that the decrease in cloudiness over the past two decades has been primarily driven by humans, rather than being caused by natural variations in Earth’s climate…

    Our research finds that about 40% of the low-level cloud decrease since 2003 was driven by warming of the ocean surface – in other words, the cloud feedback process. This is followed by the effects of greenhouse gases (21%) and aerosols (14%).”

    Major reversal in ocean circulation detected in the Southern Ocean, with key climate implications | Institut de Ciències del Mar
    https://www.icm.csic.es/en/news/major-reversal-ocean-circulation-detected-southern-ocean-key-climate-implications?

    “We are witnessing a true reversal of ocean circulation in the Southern Hemisphere—something we’ve never seen before,” explains Antonio Turiel, ICM-CSIC researcher and co-author of the study. “While the world is debating the potential collapse of the AMOC in the North Atlantic, we’re seeing that the SMOC is not just weakening, but has reversed. This could have unprecedented global climate impacts.”

    According to the research team, the consequences of this reversal are already becoming visible. The upwelling of deep, warm, CO₂-rich waters is believed to be driving the accelerated melting of sea ice in the Southern Ocean. In the long term, this process could double current atmospheric CO₂ concentrations by releasing carbon that has been stored in the deep ocean for centuries—potentially with catastrophic consequences for the global climate.
    ...
    “The new processor has allowed us to obtain surface salinity data of unprecedented quality in this region,” explains Verónica González. “Thanks to this improvement, we can now provide a coherent explanation for the rapid Antarctic sea ice loss that had puzzled the scientific community.”

    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.

    Surging Methane Emissions Could Be a Sign of a Major Climate Shift - Inside Climate News
    https://insideclimatenews.org/news/28082024/surging-methane-emissions-major-climate-shift/

    A 2021 pledge by more than 100 nations to cut methane emissions from anthropogenic sources 30 percent by 2030 might not slow global warming as much as projected, as new research shows that feedbacks in the climate system are boosting methane emissions from natural sources, especially tropical wetlands.

    A new trouble spot is in the Arctic, where scientists recently found unexpectedly large methane emissions in winter. And globally, the increase in water vapor caused by global warming is slowing the rate at which methane breaks down in the atmosphere. If those feedbacks intensify, scientists said, it could outpace efforts to cut methane from fossil fuel and other human sources.

    BP imposes hiring freeze and halts new offshore wind projects | BP | The Guardian
    https://amp.theguardian.com/business/article/2024/jun/27/bp-imposes-hiring-freeze-and-halts-new-offshore-wind-projects

    New boss Murray Auchincloss reverses move away from fossil fuels, which had weighed on company’s share price

    The head of BP has imposed a hiring freeze and halted new offshore wind projects, in an apparent attempt to placate investors who are unhappy with the oil company’s green targets.
    ...
    Looney, who had committed BP to some of the industry’s greenest climate goals, was ousted last September for failing to disclose relationships with colleagues.

    The decision to slow BP’s green ambitions has stoked concerns that Looney’s plan to move the company away from fossil fuels, with a pledge to “become a net zero company by 2050 or sooner”, may soon be derailed.

    BP has come under pressure from shareholders over its green targets because some renewable projects have proved more costly than expected, and profits from oil and gas have soared after Russia’s invasion of Ukraine more than two years ago.

    In response, the company set out plans earlier this year to cut oil and gas production by just 25% between 2019 and 2030 – well short of its previous target of a 40% reduction over the same timeframe.
    ...
    Earlier this month BP’s rival Shell set out its own plans to scale back its green growth ambitions, reducing the number of staff working on low-carbon solutions by about 200 roles while shifting the focus towards high-profit oil projects and expanding its gas business.
