TADEAS:

A landmark May 2026 study in Nature Climate Change (Duke/Fudan Universities) found that airborne microplastics are net warming agents — colored micro- and nanoplastics suspended in the atmosphere contribute to warming at a level equal to roughly 16% of that caused by black carbon (soot) (Gizmodo) . Dark or pigmented particles absorb up to 74.8 times more solar radiation than pristine clear plastic, and in regions like the North Pacific Garbage Patch, local warming from plastic rivals or exceeds that from soot. (Karmactive) Separately, microplastics also act as ice-nucleation seeds in clouds, triggering freezing at warmer-than-normal temperatures and potentially altering precipitation patterns and cloud cover globally. (psu) On glaciers, dark particles reduce surface reflectivity and accelerate melt. Storms amplify the problem: during typhoons, researchers recorded massive deposition events that redistribute ocean plastics onto land

The Trump administration is dismantling a $368 million deep-ocean monitoring network 900+ sensors tracking climate currents, fishery health, ocean carbon absorption, and coastal flooding along the East Coast. Ships go out in June to start pulling it up. Congress funded it twice after Trump tried to cut it 80%. NSF shut it down anyway. The Irminger Sea station alone was part of an international effort to monitor the Atlantic Meridional Overturning Circulation the global current system whose collapse would mean permanent, severe weather disruption across the Northern Hemisphere.

A volcano that erupted in the South Pacific in 2022 destroyed some of its own methane emissions, and scientists now think the chemistry behind it could become a new tool against one of the most potent planet-heating gases.

The Hunga Tonga-Hunga Ha'apai eruption on 15 January 2022 was one of the most violent of modern times, hundreds of times more powerful than the Hiroshima bomb, with a sonic boom that circled the planet twice. New research published in Nature Communications found that it also cleaned up after itself.

Studying satellite data, scientists spotted a huge cloud of formaldehyde, a gas that forms when methane is broken down. "We found a huge cloud of formaldehyde that should normally not be there", said study author Maarten van Herpen. They tracked it for 10 days, and since formaldehyde lasts only a few hours, the methane destruction must have continued for over a week.

The eruption blasted enough salty water vapour into the stratosphere to fill around 58,000 Olympic-size swimming pools. Sunlight hitting that salty mixture appears to have produced chlorine, which reacted with methane and broke it down, the same process previously observed when Saharan dust blows over the Atlantic. The team estimates the eruption produced around 330,000 tons of methane, of which roughly 900 tons were destroyed each day.

Why it matters: methane is about 80 times more effective at trapping heat than carbon dioxide over 20 years and accounts for roughly a third of global warming. Because it is short-lived, cutting it could slow warming relatively quickly. The findings raise the possibility of injecting iron-based particles into the air over the ocean to mimic the effect.

Independent scientists are cautious. Pete Edwards of the University of York called the results interesting but "very difficult" to confirm, warning of "potential unintended consequences on climate, air pollution and ecosystem health". Emily Dowd of the University of Leeds said the chemistry still needs thorough testing in atmospheric models before anyone counts on it.

Predstavte si 540 miliónov rokov klímy strednej Európy v jednej obrazovej sérii — od najstarších prvohôr až po to, ako môže naša krajina vyzerať o pár generácií.

Začneme v plytkom tropickom mori s trilobitmi (pred 520 mil. rokov). Pokračujeme do hustého uhoľného pralesa pri rovníku s 35-metrovými šupinatými stromami a vážkami s rozpätím krídel 70 cm (pred 310 mil. rokov). Stáda "raných" dinosaurov v polopúšti superkontinentu Pangea (pred 220 mil. rokov). Pravták Archaeopteryx krúžiaci nad tropickou bavorskou lagúnou (pred 150 mil. rokov).

V eocéne — pred 48 miliónmi rokov — bolo Nemecko ako Indonézia: palmy, krokodíly, prví primáti v korunách stromov. Bolo o 12 °C teplejšie ako dnes.

Potom dlhé ochladzovanie. Posledná doba ľadová pred 21 000 rokmi: mamutia step naprieč strednou Európou, stáda sobov a vlnatých nosorožcov, na fronte alpského ľadovca naši priami predkovia v kožiach. Pred 125 000 rokmi naopak medziľadová doba — teplejšie ako dnes, v Temži sa kúpali hrochy.

Po roztopení ľadovcov prví roľníci s drevenými dlhými domami ako ostrovy v mori hlbokých lesov. Stredoveké teplé obdobie okolo roku 1100 — anglické vinice, kvitnúce kláštory. Malá doba ľadová v 17. storočí — zamrznuté rieky, trhy priamo "na ľade".

A potom budúcnosť: +2 °C, +4 °C, +10 °C.

Najsilnejšia myšlienka? Posledný obraz série — Zem o 10 °C teplejšia okolo roku 2300 — stredná Európy vyzerá takmer identicky ako tá eocénna džungľa pred 48 miliónmi rokov. Palmy, tie isté krokodíly v rieke. More o 60 metrov vyššie. Panónska kotlina pod morom. A civilizácia? It´s gone (I suppose).

Paleoklimatológia nie je len o minulosti. Je to atlas našej budúcnosti — mapa, ktorú už raz Zem nakreslila. Stačí ju vedieť čítať.

Rainforests pushed to breaking point by new demands for resources, report says | Deforestation | The Guardian
https://www.theguardian.com/environment/2026/may/20/rainforests-pushed-to-breaking-point-by-new-demands-for-resources-report-says

Fresh demands for critical minerals, biofuels and pulp – used in fast fashion, processed food and packaging – are compounding existing pressures from cattle ranching, monocrops, oil and logging, the analysis finds.

Mining, in particular, has a far greater environmental footprint than previously thought owing to secondary impacts, such as water pollution and the construction of roads, settlements and other infrastructure development. Between 10% and one-third of the world’s forests are already affected and this proportion is expected to increase.

The authors say this highlights an urgent need to replace and reduce the use of products from forest regions, rather than simply adding new forms of consumption, as is currently the case.

The report tracks the commodity trends that are threatening forests in the Amazon, the Congo basin and south-east Asia, and weakening their capacity to regulate temperature, store carbon, recycle water and provide a home for nature.

Cattle ranching, agriculture and gold mining remain by far the biggest threats, finds the study, which was produced by the Dutch research organisation Profundo and commissioned by Rainforest Foundation Norway. All three are forecast to continue expanding.

Guest post: How declining cloudiness is accelerating global warming - Carbon Brief
https://www.carbonbrief.org/guest-post-how-declining-cloudiness-is-accelerating-global-warming/

“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."
