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.

Suicide (Paperback) – JUST RELEASED – Revolution in the 21st Century
https://rev21.earth/product/suicide/

From a cell in Wayland Prison, Roger Hallam—farmer, researcher, and co-founder of Just Stop Oil—delivers a searing indictment of a legal system that punishes those who resist, while protecting those who destroy. In July 2024, Hallam was dragged from a British courtroom for refusing to stay silent about the climate crisis. For “conspiracy to cause a public nuisance,” he was sentenced to five years in prison, the harshest punishment for civil disobedience in the UK in modern British history. The case made front-page news and drew global outcry.

Suicide is part memoir, part political reckoning. Drawing on Hallam’s award-winning research and experience representing himself in four Crown Court trials, it lays bare the moral and legal failures of a society sleepwalking into catastrophe. From climate science and the right of necessity, to the collapse of democratic norms and the illusions of secular reason, this is a radical call to rethink justice, truth, and duty in the face of extinction.

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.

Vo francúzskom Saint-Gladie namerali včera takmer 30 °C (29,6 °C) – na koniec februára mimoriadne nezvyčajná hodnota. V rovnaký deň pritom na severovýchode Európy klesali maximá hlboko pod −20 °C. Rozdiel teplôt naprieč kontinentom sa blížil až k 70 °C.

Takéto extrémy ukazujú, aké dynamické (a čoraz vyhrotenejšie) dokáže byť počasie v Európe. 🌍🔥❄️

France: A record temperature of 29.6°C was recorded this afternoon in Saint-Gladie in the Pyrénées-Atlantiques (64). That's 16°C above the norms! A temperature in line with the August monthly averages.

China's CO2 emissions were flat or slightly down, down 3/10ths of 1% in 2025. And again, every news outlet is framing this chart as proof the green transition is working. That's looking at the chart, but let's look at the system. Chinese coal production hit an all-time record of 4.8 billion tons in 2025, up 1.2%. Coal power capacity additions hit their highest level in a decade. New coal project proposals surged to a record 1.6 gigawatt and China still consumes nearly 40% more coal than the rest of the world combined.


So where did the emission savings come from?

Cement production collapsed close to 10% due to the real estate contraction. Building materials, metals, and steel all down. So the emissions decline isn't clean energy replacing dirty energy in a growing economy. It's partly a construction sector in freefall masking continued and growing coal dependence and the chemical sector which is coal to chemicals grew their emissions 12%.

This is the EU renewable story again just from the other direction. The metric and the graphics in the news — flat emissions — looks like progress. But the system — record coal, collapsing cement on a real estate crisis — tells us something very different

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.

The U.S. Supreme Court has agreed to hear a major case that could reshape how climate accountability lawsuits move forward across the country.

At issue is a lawsuit filed in Colorado that seeks to hold energy companies financially responsible for the local costs of climate change things like wildfire mitigation, infrastructure damage, extreme weather response, and public health impacts. The companies are asking the Court to throw the case out entirely.

The justices’ decision to take up the case is significant. While the Colorado lawsuit is the one directly before them, the ruling will likely determine whether similar cases brought by cities and states nationwide can proceed. Across the country, municipalities have filed lawsuits seeking billions of dollars in damages, arguing that fossil fuel companies misled the public about climate risks while continuing business practices that worsened those risks.

If the Court sides with the energy companies, many of these cases could be dismissed before they ever reach trial. If the Court allows the Colorado case to move forward, it could open the door for more local governments to pursue compensation through the courts.

This isn’t just about one state it’s about whether communities across the United States can use state courts to seek accountability for climate-related costs, or whether those efforts will be shut down at the federal level.
