EPA says power for data centers can sidestep pollution laws
By Tim McLaughlin
July 27, 2026"Power sources providing electricity only to data centers and not the public grid may not be subject to federal pollution laws, the U.S. Environmental Protection Agency said on Monday.
"The EPA said if the power plants are not supplying electricity to the grid then they would not be subject to the federal #CleanAirAct's #AcidRain Program, which has been key to the dramatic reduction of #smog and #soot pollution from industrial facilities."

So, the rain we've gotten in Southern #Maine seems pretty clear (not full of ashes), but it does not smell good. No #petrichlor . Maybe an undertone of stale smoke? Not pleasant... Also #AlkalineRain is a thing like #AcidRain. While it would seem to neutralize Acid Rain, it ends up having the opposite effect.
Can Smoke Particles Neutralize or Enhance Acid Rain?
Smoke can neutralize acid if it contains alkaline ash, but often provides surfaces that accelerate acid formation.
"Smoke particles are chemically complex and can either neutralize or enhance the acidity of rain depending on their composition. Some wildfire smoke contains alkaline ash, which can help neutralize acidic gases in the atmosphere, potentially making the resulting rain less corrosive.
"However, many smoke particles also contain #sulfur and #nitrogen compounds that act as precursors to acid formation. Furthermore, the large surface area of fine smoke particles provides a platform for acidic gases to condense and react, which can lead to more concentrated acidic deposition.
The net effect depends on the type of fuel burned and the age of the smoke plume as it moves through the atmosphere."

The Destruction of Nature is a Cost of War
by Ci Davis
We have become accustomed to seeing the human impacts of war, from starvation in Sudan to the almost 100,000 killed in Gaza, but most people will be less familiar with the environmental impacts. On February 28th, another Middle East war broke out when the US and Israel launched an attack on Iran. In the first few hours, the Supreme Leader was killed, followed by the bombing of a school, killing 150 Iranian schoolgirls, and soon after, columns of smoke began to rise from targeted hits on petrochemical infrastructures.
Over the past three weeks, oil refineries, gas fields, tankers, nuclear facilities, desalination plants, oil storage tanks, air bases, and industrial areas have all been attacked. The water, marine and toxic-air pollution are a consequence of the smoke from the multiple infernos, from the widely dispersed toxic fragments, and from the many chemicals and heavy metals that escape into the soil and water, caused by thousands of bomb and missile strikes
The human and environmental costs of another war prompted two protests in Sheffield. On 21st March, 150 people demonstrated outside the Town Hall to call for an end to the war on Iran and also made connections with other current conflicts, including Gaza, Lebanon, Sudan, Ukraine and Cuba.
Our media tends to represent the environmental impacts of war as collateral damage, an unfortunate side effect, but really, they are a deliberate and targeted means of disrupting the lives of people by making their connection to land fragile or even untenable. No clearer example exists than the use of Agent Orange to defoliate the forests of Vietnam that left millions of Vietnamese and hundreds of thousands of US veterans with multigenerational health disorders and birth defects. Environmental harm is one of the ways that war impacts lives that can last many decades.
The environmental impacts of war cannot be separated from the environmental costs of the military machine itself, which is responsible for 5.5% of global greenhouse gas (GHGs) emissions, which rose by a staggering 9.4% in 2024. The US military is the largest institutional emitter of GHGs that are responsible for climate change, burning 270000 barrels of oil daily. Countries are not required to produce figures for the wartime emissions, but recently it is estimated that the war in Ukraine has produced 237 million tonnes of CO2, the Gaza conflict 32 million tonnes and in the first 5 days of the Iran war 5 million tonnes. At a time when all countries should be doing everything to reduce climate and environmental damage, the resort to war is escalating the harm.
Apocalyptic images, showing clouds of black toxic smoke blocking out the sun over Tehran, following the bombings of local oil depots on 7th March, are haunting. The oily residues, soot and sulphur-laden smoke, combined with a rare rainstorm, produced acid rain, causing immediate respiratory impacts with a lasting health legacy. For people who had already experienced chemical weapons attacks during the Iran-Iraq war, this environmental warfare was experienced as chemical warfare again.
Impact of War on the Environment Author: Sayedqudrathashimy1991 Source: Wikimedia CommonsThe Middle East is experiencing the climate crisis through water insecurity. The conflict in Syria, which displaced 1.5 million people between 2007 and 2010, was in part precipitated by drought. There are clear parallels to Iran today. After six years of drought, the water supply to Tehran was at just 11% capacity, and the shortage of water to drink or to supply agriculture contributed to protests in January 2026. War is exploiting this suffering, with all parties having targeted water and sewerage systems that, if continued, threaten to displace people throughout the region, as well as causing severe health impacts.
Most of us will be familiar with the skeletons of buildings and mountains of debris from TV images of Gaza. The 61 million tonnes of rubble are laden with asbestos, unexploded weapons, dead bodies, and untreated sewerage that has rendered the land unfit for agriculture. The clearance will take decades and burn through hundreds of thousands more tonnes of fossil fuel, and we are seeing the same thing being repeated across Iran and the Gulf.
Years after wars end, the land, air and sea will remain contaminated. Thankfully, the deliberate targeting of the environment is becoming recognised in International Law as a war crime or ecocide and can be punished under the ICC’s Rome Statute. If it is demonstrated that the military intentionally launched an attack, knowing that it will cause long-term severe damage to the natural environment, that is excessive to the military advantage anticipated, then prosecutions may follow.
As the war drags on, it risks total destruction of the oil-fields, spillage of nuclear material, and depleted Uranium contamination. These huge environmental threats will have global impacts, experienced as economic shocks and agricultural losses, threatening food security. War demonstrates our intimate connection with the land and the importance of environmental protection.
Most people oppose the war, the use of UK bases in support of it, and sending the military to the Middle East. We should make our voices heard, calling upon world leaders to respond to our opposition and pull back from the brink, for the sake of people and the planet.

"Both timber harvest and #AcidRain have removed large amounts of nutrients from ecosystems. In places where both occurred, regrowing #trees are starved for the nutrients they need to grow, and they invest growth below ground to build roots and fuel #microbes that can extract nutrients they need from underlying bedrock."

‘We’ve done it before’: how not to lose hope in the fight against ecological disaster.
Some days it can feel as if climate catastrophe is inevitable.
But history is full of cases – such as the banning of whaling and CFCs – that show humanity can come together to avert disaster.

Scientists Are Warning of A Brand-New Kind of #AcidRain
Story by Darren Orf
Key points:
- While acid rain caused by sulfur dioxide is an environmental threat of the past (at least, for now), a new kind of acid is proliferating in rain water—as well as groundwater, ice cores, and even human blood.
- #TrifluoroaceticAcid (#TFA) is a subclass of “#ForeverChemical” that’s been steadily increasing in concentrations around the world.
- With calls to consider this rise in TFA a planetary threat, some governments are starting ban chemicals linked to TFA—but the threat will require global cooperation."Acid rain may have a sequel, and like most sequels, it’s arguably worse.
"While the world’s first bout of acid rain (at least, in modern times) came from increased concentrations of sulfuric acid produced largely from coal plants, this new #anthropogenic source is possibly more pervasive, more persistent, and more sinister. Its name is Trifluoroacetic acid (TFA), a kind of 'forever chemical' that, for decades, has been steadily increasing in #RainWater—but not just rain water.
"Countries around the world have found increasing concentrations in #groundwater, #ArcticIceCores, #wine, and even #HumanBlood. In fact, TFA is likely the most pervasive form of per- and poly-fluoroalkyl (#PFAS)—technically, a subclass known as ultrashort-chain perfluoroalkyl acid (#PFAA)—on Earth due in part to the fact that longer-chain PFAS degrade into TFA via #incinerators or #SewageTreatment plants. They’re also used in #refrigerants instead of #chlorofluorocarbons and #hydrochlorofluorocarbons, which were famously known to deplete the Earth’s #OzoneLayer.
"In October of 2024, a team of European environmental scientists raised the TFA alarm, stating that a rise in concentration could be considered a threat to '#PlanetaryBoundaries' — a system designed to make sure the planet remains #habitable for human life (which we are doing a real bang-up job at following).
" 'Since the 1990s, it has been suggested that hazard-related concerns of TFA and other short-chain PFAAs are much lower than those of PFAAs with longer perfluoroalkyl chains, which are more #bioaccumulative and generally more #toxic,' the authors wrote back in October. 'However, these early reports did not consider TFA’s ubiquitous accumulation in the environment, in particular its observed accumulation in water resources and #bioaccumulation in various plants, including crops.'
"One of the most dangerous things about PFAAs is what we don’t know about them. Unlike other PFAS (of which there are, sadly, thousands of different kinds), TFA is so small (a.k.a. ultrashort) that it’s water-soluble, meaning it likely passes through the human body pretty quickly. A new Nature article reports that some scientists find this evidence compelling enough to not even consider TFA a kind of PFAS, but a growing chorus of voices are raising concerns that increased concentrations of TFA in water and food sources could render TFA’s fast-moving nature a moot point.
"In fact, TFA’s water-solubility could be a long-term headache. If scientists and governments eventually decide that TFA does need to be removed from drinking water and other sources, current filtration technologies are not up to the task. In other words, ridding the world of TFA will not only be immensely difficult, it’ll also be incredibly expensive. Current regulations to eliminate certain forms of PFAS are already proving to be fiscally onerous.
"Thankfully, some governments are taking action. #Denmark, for example, banned 23 substances earlier this month known to contain PFAS that contribute to rising TFA concentrations. Meanwhile, the #US is lagging behind—the Environmental Protection Agency [#EPA] doesn’t even define TFA as a 'forever chemical,' much to the dismay of #environmentalist groups and to the merriment of many #industry leaders.
"Rising concentrations of TFA is the acid rain sequel no one wanted. But just like every terrible sequel ever made, it seems like we’re getting it anyway."

In fact, TFA is likely the most pervasive form of per- and poly-fluoroalkyl (#PFAS)—technically, a subclass known as ultrashort-chain perfluoroalkyl acid (#PFAA)—on Earth due in part to the fact that longer-chain PFAS degrade into TFA via #incinerators or #SewageTreatment plants. They’re also used in #refrigerants instead of #chlorofluorocarbons and #hydrochlorofluorocarbons, which were famously known to deplete the Earth’s #OzoneLayer.
"In October of 2024, a team of European environmental scientists raised the TFA alarm, stating that a rise in concentration could be considered a threat to '#PlanetaryBoundaries' — a system designed to make sure the planet remains #habitable for human life (which we are doing a real bang-up job at following).
" 'Since the 1990s, it has been suggested that hazard-related concerns of TFA and other short-chain PFAAs are much lower than those of PFAAs with longer perfluoroalkyl chains, which are more #bioaccumulative and generally more #toxic,' the authors wrote back in October. 'However, these early reports did not consider TFA’s ubiquitous accumulation in the environment, in particular its observed accumulation in water resources and #bioaccumulation in various plants, including crops.'
"One of the most dangerous things about PFAAs is what we don’t know about them. Unlike other PFAS (of which there are, sadly, thousands of different kinds), TFA is so small (a.k.a. ultrashort) that it’s water-soluble, meaning it likely passes through the human body pretty quickly. A new Nature article reports that some scientists find this evidence compelling enough to not even consider TFA a kind of PFAS, but a growing chorus of voices are raising concerns that increased concentrations of TFA in water and food sources could render TFA’s fast-moving nature a moot point.
"In fact, TFA’s water-solubility could be a long-term headache. If scientists and governments eventually decide that TFA does need to be removed from drinking water and other sources, current filtration technologies are not up to the task. In other words, ridding the world of TFA will not only be immensely difficult, it’ll also be incredibly expensive. Current regulations to eliminate certain forms of PFAS are already proving to be fiscally onerous.
"Thankfully, some governments are taking action. #Denmark, for example, banned 23 substances earlier this month known to contain PFAS that contribute to rising TFA concentrations. Meanwhile, the #US is lagging behind—the Environmental Protection Agency [#EPA] doesn’t even define TFA as a 'forever chemical,' much to the dismay of #environmentalist groups and to the merriment of many #industry leaders.
"Rising concentrations of TFA is the acid rain sequel no one wanted. But just like every terrible sequel ever made, it seems like we’re getting it anyway."

The occasional complaints we see coming out of the US, about how smoke from wildfires in Canada is affecting USAnians (or, as some have put it, "ruining their summer") are a bit rich. Besides the whole "the fires are due to climate change, which the USA is one of the worst contributors to, and besides they're trying to become *worse* on purpose" thing, it's both hypocritical and completely ignorant of (recent!) history.
In the 1970s and 1980s, the big environmental issue in a large part of the west was acid rain. It was hard on everything from gardens and crops to the finish of your car. And the acid rain falling in (for example) southern Ontario was almost completely due to industrial smokestacks in the USA, from Michigan to Pennsylvania.
Anyways, just wanted to get that off my chest.

A new study connects recent regionally confined warming in China 2010ff to their strive for healthy air by scrubbing SO2 from their coal chimneys. *
In other news, India is lambasted by a politician for excluding most of their coal chimneys from SO2 scrubbing regulation. **
And here's a curious side effect of acid rain from SO2:
it reduces CO2 emissions from soil 💡
https://www.sciencedirect.com/science/article/abs/pii/S0341816221005725 "Acid rain reduces soil CO2 emission and promotes soil organic carbon accumulation in association with decreasing the biomass and biological activity of ecosystems: A meta-analysis" by Ziqiang Liu et al 2022So when large areas simultaneously get rid of SO2 pollution
, CO2 emissions start to rise noticeably? Europe's SO2 reduction was fastest, USA is her typical laggard, and China began 2010ff and is now already on par with a mid-1990s Europe, much faster than USA.
My musings:
I guess, it means, once the soil removes the acid, CO2 emissions start to rise.
AFAIK, acid removal is no automatism in forest soil but I can imagine, removal from agricultural land happens automatically bit by bit during subsequent harvests? (Yum!)Germany distributed chalk or something to her forest soils to counter the acidification and to rescue dying forests.
But. Plants and other beings suffer during acidification. And when forests recover they raise their carbon uptake. Crop yields also recover when the soil does, I reckon. (Indeed! see *** and pic 2, and also ****. Now I wonder whether the elsewhere celebrated yield gains are more due to cleaner air than genetical engineering and pesticides!)
Maybe, CO2 emissions from soil are balanced out by increased carbon uptake from healthier beings.
Does the paper say anything about all these musings?"Overall, the responses of soil GHGs emissions to acid rain vary across different ecosystems, climates, soil types and experimental duration, and thus no consensus has emerged yet" 😁

The main reasons for the release of heavy metals into the environment
What is more interesting: the main reasons
for the release of heavy metals into the environment are wastewater from various industrial facilities, some pesticides and fertilizers, acid rain (i.e. acidification).
Acid rain is associated with the fact that by reducing the pH of the soil, metals dissolve, falling into the aquatic environment. -

Interesting. Regarding the cooling from own SO2 emissions, China has done a U-turn like Europe, and is now at the cooling stage that Germany experienced in the early 1990s, from 10mio t SO2.
I say Germany, because due to the #jetstream it inherited the impact of the atmospheric SO2 emissions from North, West, and South, but not from East Europe, I guess. (While East Europe enjoyed SO2 from everybody else.)West-Germany in the early-mid 1990s was constantly flooded in my memory. I should look it up tho.
At the hight of forest die-off from acid rain, emissions in the Germany-impacting regions peaked at 35mio t SO2.
Exactly where China was in 2005.India now has 10mio t own emissions, as well. As does West Asia, from where India inherits a little atmospheric SO2, I guess. So both are also comparable to Germany in the early 1990s.
But India's SO2 emissions are still growing steeply. No U-turn in sight. West Asia is still recovering from Covid fallout, difficult to tell where they might be going.Haven't heard anything from Asia wrt #AcidRain. Have you?
Maybe their tree species and soil critters are more robust?
