“For the past two decades, low-level cloud cover has been declining, increasing the amount of sunlight absorbed by Earth and amplifying global warming.

As global temperatures have reached record highs in recent years, there has been concern that the decline in cloudiness may be enhancing warming more than previously expected.

In a new study, published in Atmospheric Chemistry and Physics Letters, we investigate how the decline in global cloudiness affects the Earth’s “energy imbalance” – the difference between absorbed solar energy and heat radiated into space that results in global warming.

This imbalance has more than doubled over the past 20 years, as greenhouse gases have trapped more heat in the atmosphere.

We find that, since 2003, the decrease of cloudiness has been responsible for half of the increase of Earth’s energy imbalance.”

“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%).”

Globally, permafrost is estimated to contain 1,700 billion metric tons of carbon, which is roughly three times the amount currently in the atmosphere.

Reduced economic activity caused by the current Iran war has not been sufficient to offset the surge in CO₂ emissionsgenerated by the conflict. While economic slowdowns typically lead to modest declines in emissions, the scale of disruption in this case has been relatively limited on a global level.

At the same time, the war has produced a sharp and concentrated spike in emissions from infrastructure destruction, fires, and intensified military operations, resulting in a clear net increase in CO₂ output. A key reason is that war-related emissions are largely additive rather than substitutive. Military fuel use, explosions, and the burning of oil and buildings introduce new emissions on top of ongoing civilian and industrial activity, rather than replacing it. Moreover, the destruction of infrastructure creates a pipeline of future emissions, as rebuilding cities, roads, and energy systems requires large amounts of carbon-intensive materials like cement and steel. These delayed emissions often outweigh any short-term reductions from decreased economic activity.

In addition, the war is triggering indirect effects that further raise emissions, such as shifts toward dirtier energy sources, increased fossil fuel investment for energy security, and longer transportation routes due to regional instability. Historical patterns from other conflicts show that even when emissions dip briefly during periods of disruption, they tend to rebound and exceed prior levels during recovery and reconstruction. Overall, the evidence indicates that the Iran war is contributing to a net increase in emissions both immediately and over the longer term, rather than being offset by reduced economic output.

Pesticides, pharmaceuticals and industrial chemicals found everywhere in seawater
https://www.lemonde.fr/en/environment/article/2026/03/22/pesticides-pharmaceuticals-and-industrial-chemicals-found-everywhere-in-seawater_6751696_114.html

The researchers detected a total of 248 human-made compounds in the waters of the Pacific, North Atlantic and Indian oceans, which, across all the samples analyzed, made up a median of 2% of dissolved organic matter. Among these were pesticides such as DEET and icaridin (both insect repellents), additives used in plastics such as phthalates, UV filters from cosmetics, surfactants and a whole range of pharmaceutical residues, including beta-blockers, antidepressants and anti-infectives such as chloroquine.

The analyses also revealed that levels of chemical pollution were particularly high near coastlines, with a median proportion of contaminants from human activity amounting to 20% of all dissolved organic matter, and reaching as much as 63% in the most extreme cases.

"I was quite shocked when we first saw the results. (...) When you think about it from a hydrological perspective, I think this also makes complete sense," noted Petras. "In Germany, for example, during the summer months, a large portion of water contribution to the major rivers comes from wastewater treatment plants. Those can currently not remove all/most of the organic compounds, so they will end up in the river and then in the ocean."

Marine waters contain "about 700 billion metric tons of dissolved organic carbon – a mix of proteins, carbohydrates, lipids and other molecules – mainly from the biological activity of marine organisms and river inputs," explained Sempéré. The fact that human-made molecules in the ocean account for 2% of the chemical signal is, in his view, "far from negligible," and a figure of 20% in coastal areas "is huge."

Energy crises must accelerate the fight against climate change
https://www.lemonde.fr/en/opinion/article/2026/03/21/energy-crises-must-accelerate-the-fight-against-climate-change_6751671_23.html

Breaking free from dependence on fossil fuels is, beyond the climate benefits a crucial issue of national sovereignty and the only way to protect ourselves against geopolitical shocks, such as those caused by the war in the Middle East.

The mistake would be to respond to this situation with broad subsidies for fossil fuels, as was done in 2022. At the time, the urgency justified massive price controls. Today, France no longer has the budgetary means, and Europe cannot afford to indefinitely subsidize its dependency.

Every euro of public funding must be directed toward measures that structurally reduce fossil fuel consumption: thermal renovation of buildings, electrification of uses and support for low-carbon industrial sectors.

Informal Institutions in Policy Implementation : Comparing Low Carbon Policies in China and Russia
Anna Korppoo, Iselin Stensdal, Marius Korsnes


"At a time of global climate crisis, this crucial book examines the prospects for implementing low-carbon policies in the two global superpowers of China and Russia, focusing on the role of informal institutions in achieving reductions in greenhouse gas emissions. Chapters shed light on how informal institutions function and work in practice, how and why they take shape and how they influence formal low-carbon policies. Forensically examining five critical cases relating to Chinese and Russian institutions, this book demonstrates how informal institutions can both support and obstruct the achievement of formal policy goals. Through comparisons within and between each country, it shows how these dynamics differ and offers key hypothesis on the role of these institutions in policy implementation. Comprehensive and incisive, this book will be important reading for scholars researching public policy in China and Russia, particularly those specialising in environmental science and politics. The practical insights derived from new case studies will also be useful for policymakers working on climate mitigation policy"-- Provided by publisher

SHEFIK: taktohle je podobné těm dratům v mořské vodě, na kterých se ti dělá vápenec. Otázkou je ten zdroj energie...

Taky historicky jsme se zajímali o doplňování kyslíku do atmosféry (jeho podíl totiž neustále klesá) a původní logika ve prospěch zalesňování a zazeleňování byla i tato - tedy produkce kyslíku. O tom se dnes už vůbec nemluví. Ale pokud CO₂ odbouráme nějakými industriálními postupy, tak se ten kyslík neuvolní (u téhle reakce vzniká uhličitan sodný, ale v tom je toho kyslíku spousta lapeného...)

Proto si myslím, že zazeleňování, tedy zvětšování kapacity biosféry, je přeci jen nejčistší cesta, protože řeší i druhou stránku rovnice - vrácení kyslíku do oběhu, nejen odbourání oxidu uhlčitého. Carbon capture bez té druhé poloviny rovnice je v jistém smyslu i trochu nebezpečný projekt. Atmosférický kyslík potřebujeme, není ho nekonečně.

Lesy nie sú len zásobárňou uhlíka, ako sa často hovorí. Nová vedecká štúdia ukazuje, že pre naše prežitie sú ešte dôležitejšie. Okrem toho, že viažu CO₂, regulujú teplotu a vodný cyklus tak, aby nám uľahčili život.

Výskumníci zhrnuli desiatky štúdií a zistili, že v lese je počas dňa v priemere o 4 °C chladnejšie než na priľahlých lúkach; v tropických oblastiach je rozdiel často dokonca väčší než 6 °C. V mestách dokáže stromová zeleň znížiť teplotu o 1,5–1,7 °C. Počas vĺn horúčav býva v lesoch pocitovú teplotu až o 6–14,5 °C nižšiu ako na otvorených priestranstvách.

Toto ochladzovanie nie je len príjemné, ale zachraňuje aj životy. Odlesňovanie v trópoch vystavuje stovky miliónov ľudí vyšším teplotám a prispieva k desiatkam tisíc úmrtí ročne v dôsledku prehriatia. Výskumníci tiež upozorňujú, že lokálne otepľovanie spôsobené výrubom môže byť v niektorých regiónoch porovnateľné alebo silnejšie ako samotný signál globálneho otepľovania.

Lesy sú zároveň dôležitou súčasťou vodného cyklu. Zachytávajú zrážky, zlepšujú vsakovanie a dopĺňajú podzemné vody. Odparovaním vracajú vlhkosť do atmosféry a stabilizujú prietok riek. V tropických a monzúnových regiónoch znižujú riziko záplav, no v suchších oblastiach môže prílišná výsadba stromov naopak znížiť dostupnosť vody.

Dôležitý je aj kontext. Najväčší prínos majú prirodzené "staré" lesy a to predovšetkým na miestach, kde sa prirodzene vyskytovali aj v minulosti. Vysádzať stromy do stepí či tundry sa nemusí oplatiť: tmavé koruny absorbujú viac slnečnej energie ako svetlé trávnaté plochy alebo sneh a môžu spôsobiť lokálne oteplenie. Naopak, staré porasty majú jedinečnú schopnosť tlmiť teplotné výkyvy a regulovať kolobeh vody.

Lesy ovplyvňujú aj veľkopriestorové procesy: uvoľňujú organické zlúčeniny, ktoré pomáhajú tvoriť oblaky, a recyklujú vlhkosť, čo ovplyvňuje zrážky aj stovky kilometrov ďaleko. Výskum z Bornea ukazuje, že rozsiahla strata lesa zvyšuje denné teploty, zintenzívňuje extrémy a významne znižuje množstvo zrážok, čo priespieva k väčšiemu suchu.

Lesy teda pôsobia ako klimatická "infraštruktúra": ochladzujú, hospodária s vodou a zmierňujú extrémy lepšie než mnohé technické riešenia. Nemôžu síce zastaviť globálne otepľovanie, ale môžu urobiť teplejší svet znesiteľnejším. Aj preto odborníci zdôrazňujú, že ochrana a obnova pôvodných lesov patrí medzi najefektívnejšie a najlacnejšie formy adaptácie na zmenu klímy.

Forests don’t just store carbon. They keep people alive, scientists say

SKORZENY: refeeuje to k segmentu predtim v tom samem videu:

Wind and solar reaching 30% in the EU is the visible numerator of a fraction whose denominator is shrinking. Industrial demand is leaving Europe which makes the renewable share look better while the economy gets worse. The energy transition did add renewables, but it also shut down nuclear, replacing zero-carbon base load with intermittency, severed Russian gas, replacing cheap pipeline gas with expensive LNG, and layered on carbon taxes and grid surcharge charges that made the total system cost uncompetitive.

Europe is running a real-time experiment in whether an advanced industrial economy can maintain its productive capacity at today's superorganism throughput level while fundamentally restructuring its energy system. And so far the answer is not without enormous economic pain and possibly not at all.

Researchers from ETH Zurich have found that two large lakes in the Democratic Republic of Congo — Lakes Mai Ndombe and Tumba — are releasing carbon that’s been locked away in surrounding tropical peatlands for thousands of years.

By analysing dissolved carbon in the lakes, they discovered that roughly 40% of the CO₂ emissions come from peat deposits 2,000–3,500 years old, not just from recent plant material. This shows that tropical peatlands, long considered stable carbon stores, can leak ancient carbon back into the atmosphere.

The study highlights a hidden climate risk: these peatlands could contribute to atmospheric CO₂, especially if disturbed by climate change or land‑use changes, challenging assumptions about how securely carbon is stored in tropical ecosystems.

France bets on nuclear in new plan to cut fossil fuel imports
https://www.lemonde.fr/en/environment/article/2026/02/12/france-bets-on-nuclear-in-new-plan-to-cut-fossil-fuel-imports_6750431_114.html

France's government on Thursday, February 12, presented an energy plan to use less imported fossil fuels, including by ramping up nuclear-fuelled power production over the next decade. France wants to phase out fossil fuels by 2050, and is hoping consumers will switch from burning oil and gas to consuming more low-carbon electricity to do so.

The plan, spanning from 2026 to 2035, foresees more use of the country's 57 nuclear power plants and the construction of six new ones, as well as more energy from offshore wind farms. But it aims to rely less on solar parks and land-based wind farms. The move is a reversal from a plan for 2019 to 2024, which had called for shutting down several of France's nuclear reactors.
