What is moving · 1 of 4

Fuel getting dearer

High ↑

Diesel in Britain passed 2 pounds a litre for the first time. [13] US petrol costs about $4.40 a gallon, around 40% more than a year ago. [11] Electrek says dear petrol has replaced most of the US demand Tesla lost when the tax credit ended. [3]

What is moving · 2 of 4

Grids running out of room

Building ↑

Denmark passed an emergency law ranking who may connect to its full grid. [16] Japan has 172 gigawatts of grid batteries waiting in line, against 0.64 gigawatts connected. [17] Germany now lets batteries charge from the grid and sell power back when it is dear. [23]

What is moving · 3 of 4

US support pulled back

High ↑

The US cut its 2031 mileage target, and 26 states, cities and counties sued on Friday. [9] US sales of electric lorries are near a standstill after tax credits ended and grants were frozen. [15] A campaign group counts 3,446 clean-energy factory projects hit by US policy changes. [27]

What is moving · 4 of 4

Rain and rising water

Building ↑

About 40 people have died in Thailand's floods, and Bangkok's 50 districts are a disaster zone. [19] Nepal's Gandak river rose to its highest level since the 1960s. [20] The head of Aviva, a big British insurer, says 115,000 new English homes are planned in flood zones. [28]

Britain sells a record 99,199 electric cars in September, as Ford's US electric sales fall 80%

Swipe up for the story ↑Scroll down for the story ↓

Britain registered 99,199 battery-electric cars in September, a record, up 36.3% on a year earlier and 28.3% of all new cars, the carmakers' trade group SMMT says. [1]

Who is involved

Who is involved

Why it matters

Watch the UK government's review of the mandate: if it gives carmakers more credit for plug-in hybrids, Electrek expects more hybrids and slower growth in fully electric sales. [1]

What's really going on

Britain kept a rule that makes carmakers sell a rising share of electric cars, and in September they sold a record 99,199. [1]

What's really going on

The US ended its $7,500 buyer credit last September and its mileage fine is zero, and Ford sold 80% fewer electric cars than in last year's rush quarter. [2][3][12]

Why it works on people

A fall of 80% sounds like buyers turning away, but it is measured against the three months when US buyers rushed to beat the end of the tax credit.

Who gains

It sells an electric car at almost every price, and its electric registrations in Europe rose 58% this year. [5]

Who pays

Its shares hit a record low after it withdrew its sales forecast, down about half this year. [6]

Nobody knows yet

How far US demand for electric cars has really fallen.

Ford's 80% drop and Tesla's 2.1% dip are both measured against the rush before the credit ended in September 2025, and no source separates the rush from the slump. [2][3]

Nobody knows yet

What share of new US cars are electric.

One Electrek report puts it at about 6% to 7% this year, and another, the same day, at 8%. We show the lower range and cannot check either. [4][1]

Nobody knows yet

Whether Britain will ease its mandate.

The UK government's review is under way, and SMMT wants targets closer to demand; more credit for plug-in hybrids would change what carmakers push. [1]

Nobody knows yet

Whether Ford can build its Fathom pickup to sell at $28,350.

Ford's chief said a BYD battery once had about a 20% cost advantage, and that Ford has not yet reached mass production of the new design. [8]

Good news

Britain registered 99,199 battery-electric cars in September, more than in any month before. Cars with a plug made up 45.3% of all new cars sold there.

The whole story, in 13 parts ↓

Part 1 of 13 · Who else is involved

Part 2 of 13 · How it unfolded

Part 2 of 13 · How it unfolded

Part 3 of 13

Counting plug-in hybrids, cars with a plug were 45.3% of September's sales.

Part 3 of 13

Petrol cars fell from 45.2% to 37.6% of the market in a year. [1]

Part 4 of 13

Britain's rule, the zero-emission vehicle mandate, requires 33% of each carmaker's sales this year to be electric, up from 28% in 2025. [1]

Part 5 of 13

Carmakers can earn credits and borrow from later years to avoid fines, so New AutoMotive, a group Electrek cites, puts the real 2026 target at 24.6%. [1]

Part 6 of 13

There are 178 electric models on sale in Britain, more than double the 2023 count and about twice the US choice. [1]

Part 6 of 13

Electrek, an electric car news site, says the mandate made carmakers bring them and cut their prices. [1]

Part 7 of 13

SMMT's chief, Mike Hawes, credited more models and high fuel prices for the record.

Part 7 of 13

He wants the targets brought closer to demand in a government review. [1]

Part 8 of 13

In the US, Ford sold 6,047 electric cars from July to September, 80% fewer than a year earlier, including just 289 F-150 Lightning pickups. [2]

Part 9 of 13

A year earlier, US buyers rushed to claim a $7,500 federal tax credit before it ended on 30 September 2025, so this quarter is measured against a rush. [3]

Part 10 of 13

Tesla delivered 486,532 cars worldwide, 2.1% fewer than its all-time record in that rush quarter, but about 25,000 more than Wall Street expected. [3]

Part 11 of 13

Electric cars have been about 6% to 7% of US car sales this year, down from a peak above 10% in 2025, Electrek reports. [4]

Part 11 of 13

Rivian, a US electric carmaker, still delivered 58% more than in the previous three months as its smaller R2 arrived. [4]

Part 12 of 13

Kia's electric car registrations in Europe rose 58% from January to August.

Part 12 of 13

Its entry-level electric car there, the EV2, from 26,600 euros in Germany, is not coming to the US. [5]

Part 13 of 13

Volvo Cars withdrew its sales forecast after selling 11% fewer cars in the quarter.

Part 13 of 13

It blamed China and a slow US, and said Europe remains resilient. [6]

US states sue to bring back the mileage rule

Swipe up for the story ↑Scroll down for the story ↓

California, New York and two dozen other states, cities and counties sued the US Transportation Department on Friday. [9]

They want back the stricter fuel-economy rule it cut on Monday, from an average of 50.4 to 34.9 miles a gallon for 2031 cars. [9]

Five environmental groups, including the Sierra Club, filed a separate suit the same day. [10]

NHTSA, the department's road-safety agency, estimates a new car's driver will pay $1,624 more for fuel over the car's life. [11]

Why it matters

The states say drivers lose nearly $220 billion in fuel savings. [9] Congress had already set the fine for missing the federal target at zero. [12]

Why it matters

That leaves California's own emissions rules, which 18 other states and the District of Columbia have adopted, as the main limit on carmakers. [12]

How it works

Why a target on carmakers puts electric cars in the showroom

How it works

Britain fines carmakers who sell too few electric cars, so the carmakers bring more models and cut prices to sell them.

How it works · step 1 of 5

A government sets a share of sales that must be electric

How it works · step 2 of 5

A carmaker that falls short faces fines

How it works · step 3 of 5

So the carmaker brings more electric models and cuts their prices

How it works · step 4 of 5

Buyers find more choice at lower prices, and sales rise

How it works · step 5 of 5

Take the fine away, and the carmaker sells whatever earns it most

The twist

A rule that fines carmakers for every electric car they fail to sell makes the carmaker do the selling, with more models and lower prices.

The picture

Electric car models on sale. The US number is half of Britain's, from Electrek's 'about twice' comparison, so it is approximate.

Seen the same day

US states sue to bring back the mileage rule

The US fine for missing its mileage target is already zero, so the target no longer pushes carmakers, and the states are suing to bring back a stricter one.

Seen the same day

Chinese carmakers pour into Argentina

Argentina dropped tariffs on 50,000 electric and hybrid cars, and Chinese sellers brought their cars in, from about 2% of sales to 10%.

The catch

The push is only as strong as the fine.

The catch

Britain lets carmakers earn credits and borrow from later years, which puts the real target nearer 24.6% than 33%, and their trade group is asking for it to be eased.

The whole

A buyer in a British showroom sees 178 electric models and a discount. The target behind them sits in a law the buyer never reads.

The whole

A US driver paying about $4.40 a gallon lives with the opposite decision, made in a different law.

Who gains

The states say the nearly $220 billion drivers lose in fuel savings under the weaker mileage rule will benefit oil companies instead. [9]

Who pays

NHTSA's own estimate is $1,624 more for fuel over each car's life under the weaker rule. [11]

Nobody knows yet

Whether the courts restore the US mileage rule.

The states argue the rule is not set at the 'maximum feasible' level the law requires, and the environmental groups' petition does not yet state its legal arguments. [9][10]

Diesel passes 2 pounds a litre in Britain

Swipe up for the story ↑Scroll down for the story ↓

The average price of diesel in Britain rose above 2 pounds a litre for the first time, the RAC, a British motoring group, said. [13]

Filling a family car with diesel now costs about 110 pounds, almost 32 pounds more than when the war with Iran began. [13]

The cost of filling an average family car with diesel in Britain. The February figure is today's price minus the rise the RAC reports.

More than half of Britain's diesel is imported, and about 17% of its supply comes from the US. [13]

On Friday, EU governments discussed a French plan to release 50 million barrels of their emergency diesel. [14]

Why it matters

President Donald Trump has threatened to stop US diesel exports unless Europe releases more of its reserves, and a ban would push prices up in Britain and the EU, the BBC reports. [13]

Why it matters

Dear diesel also raises the cost of moving goods and growing food, so it reaches people who never fill a tank. [13]

Who pays

Filling a family car now costs about 110 pounds, almost 32 pounds more than when the Iran war began. [13]

Electric lorry sales set a record

Swipe up for the story ↑Scroll down for the story ↓

Nearly 160,000 medium and heavy electric lorries were sold worldwide in the first half of 2026, about 75% more than a year earlier, BloombergNEF, an energy research firm, counts. [15]

9 of 10

electric lorries sold in China, out of every ten sold worldwide

More than nine of every ten electric lorries sold in the first half of 2026 were sold in China.

More than nine in ten were sold in China, which BloombergNEF says has strong policies and its own battery supply chain. [15]

About one truck in five sold in China is now electric. [15] In the US the market is near a standstill after tax credits ended and grants were frozen. [15]

Why it matters

Dearer diesel since the Iran war makes an electric lorry pay back its higher price faster. [15]

Why it matters

In the first half, China exported more than twice as many electric tractor units, the front part that pulls a trailer, as in all of 2025, Bloomberg News reports. [15]

Who gains

More than nine in ten of the world's electric lorries were sold in China, and its exports of electric tractor units in the first half were double all of 2025. [15]

Good news

Nearly 160,000 electric lorries were sold around the world in the first half of 2026, about 75% more than a year earlier.

Denmark ranks who gets onto its grid

Swipe up for the story ↑Scroll down for the story ↓

Denmark's parliament has passed an emergency law that ends first-come, first-served connections to its electricity grid. [16] Grid companies, led by the state-owned operator Energinet, will sort applicants into four groups. [16]

Vital public services, new homes and ordinary use come first, then electric transport, heating, industry and renewable power. [16]

Batteries come third and the largest users, such as data centres, last, and those two groups can be refused when there is no room. [16]

Why it matters

Denmark's climate minister, Samira Nawa, called the state of the grid deeply serious. [16] The law starts on 12 October, and Finland is considering a similar system. [16]

Japan makes battery projects prove their land

Swipe up for the story ↑Scroll down for the story ↓

Since 1 October, any project in Japan granted a grid connection must prove within two months that it has the right to use its site, or lose its place. [17]

The rule comes from OCCTO, which coordinates Japan's power grids, and the industry ministry. [17]

At the end of 2025, about 172 gigawatts of grid batteries were waiting for a grid study, against 0.64 gigawatts actually connected. [17]

Grid batteries in Japan at the end of 2025. The connected amount is too small to see beside the queue.

At the end of September 2024 the queue was about 88 gigawatts. [17]

Why it matters

Japan's industry ministry says projects with little chance of being built were holding places, slowing the ones that could connect. [17]

Why it matters

It is the third rule this year aimed at the queue, after a cap on how many studies one company may ask for. [17]

Nobody knows yet

How much of Japan's 172-gigawatt battery queue is real.

The new rule makes projects prove their sites within two months, and nobody has said how many will drop out. [17]

Petrobras finds more oil off the Amazon mouth

Swipe up for the story ↑Scroll down for the story ↓

Petrobras, Brazil's state oil company, said on Friday it had found more oil in very deep water off Amapa state. [18]

The find is a second, deeper layer in the Morpho well, where it first found oil in August. [18]

The well is in the Foz do Amazonas basin, at the mouth of the Amazon, which Petrobras calls its most promising new oil frontier. [18]

Its chief executive, Magda Chambriard, said three more wells will test whether production would pay. [18]

Why it matters

The rocks there resemble those off Guyana, where ExxonMobil is developing huge oil fields. [18] Petrobras still needs licences for seven more wells in a basin Reuters describes as environmentally sensitive. [18]

Nobody knows yet

Whether Petrobras's find near the Amazon mouth can be pumped at a profit.

Three more wells must be drilled to tell, and seven more still need licences. [18]

Thailand's floods kill about 40

Swipe up for the story ↑Scroll down for the story ↓

About 40 people have died in the floods, some drowned and some electrocuted, the Thai government says. [19]

In parts of Bangkok roughly 300mm of rain fell in about two days, as much as London gets in half a year. [19]

All 50 of the city's districts are declared a flood disaster, and thousands of people stayed in more than 230 shelters. [19]

At one point this week about half of Thai Airways' staff could not get to work. [19]

Why it matters

Bangkok sits on the floodplain of the Chao Phraya river and drains through canals, pumps and dikes. [19]

Why it matters

Building over much of the canal network has left the city unable to cope with rain this heavy, the Guardian reports. [19]

Who pays

About 40 died in the floods, and thousands stayed in more than 230 shelters. [19]

Nepal's Gandak river hits a record

Swipe up for the story ↑Scroll down for the story ↓

Torrential rain from 24 to 27 September pushed the Gandak river, also called the Narayani, to record levels in Nepal and India, NASA reports. [20]

A gauge at Devghat in Nepal reached 11.94 metres on 27 September, the highest since measurements began in the 1960s. [20]

Water broke through embankments and flooded farms and towns for hundreds of kilometres, including parts of Bagaha in India. [20]

Why it matters

News reports say hundreds of villages were hit and thousands of people driven from their homes. [20]

Why it matters

The river runs from Nepal's mountains into India, so the rain in one country flooded villages in the other. [20]

Northwest buyers must pay for an idle coal plant

Swipe up for the story ↑Scroll down for the story ↓

The Federal Energy Regulatory Commission, which oversees US power markets, on Thursday rejected TransAlta's plan to recover $19.9 million for keeping its Centralia coal plant in Washington state open. [21]

The US Energy Department ordered the 730-megawatt plant to stay open in December, and has renewed the 90-day order since. [21] The plant made no electricity this year, through July. [21]

FERC said TransAlta may still be paid, but only by power buyers in the Northwest. [21]

Why it matters

TransAlta had wanted grid operators as far away as California and the central US to share the bill. [21]

Why it matters

Washington state's government and public power companies had argued nothing was owed for a plant that was not running, and FERC disagreed. [21]

Who gains

FERC ruled it can still be paid for keeping a plant open that made no power, from Northwest buyers. [21]

Who pays

FERC said only they should pay for the coal plant kept open by federal order, starting with $19.9 million for its first order. [21]

The US heads for its hottest year

Swipe up for the story ↑Scroll down for the story ↓

January to August 2026 was the hottest such stretch in the lower 48 US states since records began in 1895, according to NOAA, the US weather agency. [22]

It averaged 57.98F, just above the 2012 record for those months. [22]

The climate scientist Zeke Hausfather puts the chance that 2026 beats 2024 as the hottest full year at about 80%. [22]

A NOAA spokesperson said its data do not settle that yet. [22]

Why it matters

To miss the record, the last four months would need to be cooler than a typical recent autumn, Hausfather says. [22]

Why it matters

Kim Cobb, a climate scientist at Brown University, says a very strong El Nino could make 2027 worse. [22]

Nobody knows yet

Whether 2026 will be the hottest US year on record.

Zeke Hausfather puts the odds at about 80%, and NOAA says its data do not settle it yet. [22]

Germany lets batteries trade with the grid

Swipe up for the story ↑Scroll down for the story ↓

Germany's grid regulator, the Bundesnetzagentur, has approved long-awaited rules for batteries and for car chargers that can send power back. [23]

Until now, a battery storing subsidised solar power had to keep it apart from power bought from the grid. [23]

Now a battery can charge from the grid when power is cheap and sell it back when it is dear, without losing its solar support. [23]

Two-way car chargers count the same way. [23]

Why it matters

Germany's solar industry group called the rules a long-awaited key to using solar and grid power in one battery. [23]

Why it matters

It says batteries can now make better use of the grid already built, once meter and network operators put the rules in place. [23]

Chinese carmakers pour into Argentina

Swipe up for the story ↑Scroll down for the story ↓

Buenos Aires held its first Chinese car show on Friday, with more than 20 Chinese brands. [24] Argentina lets in up to 50,000 electric and hybrid cars this year without tariffs. [24]

Chinese brands took 10% of car sales in August, up from about 2% late last year, and BYD, a Chinese electric carmaker, is already the ninth best-selling brand. [24]

China is expected to export about 12 million cars this year, up from about 3 million in 2022. [25]

Why it matters

Ford's chief executive, Jim Farley, said on Tuesday that it is too late for Europe to hold back Chinese carmakers. [25]

Why it matters

The US keeps them out with tariffs above 100% and a ban on Chinese car software. [25]

How it works

Chinese carmakers pour into Argentina

Argentina dropped tariffs on 50,000 electric and hybrid cars, and Chinese sellers brought their cars in, from about 2% of sales to 10%.

The idea, in story 2: Why a target on carmakers puts electric cars in the showroom →

Who gains

A tariff-free allowance for 50,000 electric and hybrid cars took their share from about 2% to 10%. [24]

Europe's seas had their hottest summer

Swipe up for the story ↑Scroll down for the story ↓

European seas averaged 21.6C from June to August, the highest in 45 years of data, a Reuters analysis found. [26]

A marine heatwave is five or more days of water well above its usual temperature. [26]

The Bay of Biscay, off France and Spain, had 186 such days by the end of August. [26] In the 1980s it had only a handful a year. [26]

Why it matters

A marine ecologist at the University of Oviedo estimates that about 95% of the big kelp stands off Asturias in northern Spain have gone since 2010. [26]

Why it matters

Kelp needs water below about 20C, and the fish and shellfish that small fishing fleets there live on depend on it. [26]

A map of US clean factories hit by policy cuts

Swipe up for the story ↑Scroll down for the story ↓

The BlueGreen Alliance, a US campaign group that tracks clean-energy jobs, has published a map of 3,446 manufacturing projects it says have been hurt by Republican policy changes. [27]

The harms include lost tax credits, grants cancelled or delayed, and factories cancelled or stalled. [27] Lost tax credits are the largest group. [27]

An earlier report by the group put the losses at more than 111,000 jobs and $82 billion of investment. [27]

Why it matters

The tax credits were cut by a law Republicans in Congress passed in 2025. [27]

Why it matters

The new map lists jobs and money affected on each project but gives no new total, so it shows where the cuts landed rather than their full size. [27]

Who pays

A campaign group counts 3,446 projects hit by cuts to tax credits and grants. [27]

Aviva warns of homes built to flood

Swipe up for the story ↑Scroll down for the story ↓

Amanda Blanc, head of the insurer Aviva, said England is building homes that may one day be impossible to insure because of flooding. [28]

On current plans about 115,000 new homes will go up in flood zones in the next decade, she told the BBC. [28]

Aviva's research found one in nine homes built from 2022 to 2024 is at medium to high flood risk. [28]

About 6.3 million homes and businesses in England are at risk of flooding. [28]

Why it matters

The Met Office estimates that record wet winters like 2023-24 have gone from once in 80 years to once in 20 at today's warming. [28]

Why it matters

Blanc said homes built next to flood zones also need to be built differently. [28]

A California beach town votes on buying sand

Swipe up for the story ↑Scroll down for the story ↓

San Clemente, a California beach town of 62,000 people, votes in November on a 1% sales tax to pay for sand and wildfire protection. [29]

Rising seas and higher waves have split its North Beach, and crumbling cliffs keep closing a coastal railway, AP reports. [29]

The 7-mile stretch is part of a 351-mile line linking San Diego, Los Angeles and San Luis Obispo. [29]

The city says it is short of about 3 million cubic yards of sand. [29]

Why it matters

Trucking that much sand in would take 300,000 trips, the city manager says. [29] The railway also carries freight and military traffic, so the erosion reaches well beyond one beach. [29]

The world's tallest wind turbine reaches full height

Swipe up for the story ↑Scroll down for the story ↓

A pilot wind turbine in Schipkau, eastern Germany, has reached its full height of 365 metres, the tallest in the world. [30]

Its hub sits 300 metres up, where winds are stronger and steadier. [30]

GICON, which built it for Germany's innovation agency SPRIND, says it could make about twice the energy of a normal turbine with the same blades. [30]

It is rated at 3.8 megawatts and is due to start up in November. [30]

Why it matters

GICON says Germany's existing wind farms could hold up to 4,000 such turbines above the ones already there, with no new land. [30]

Why it matters

That is an estimate, and the extra output has not yet been shown in operation. [30]

Nobody knows yet

How much more power the 365-metre turbine really makes.

GICON's doubling is an estimate, and the turbine does not start until November. [30]

Ford's Michigan solar farm is finished

Swipe up for the story ↑Scroll down for the story ↓

DTE Energy, a Detroit power company, has finished a 100-megawatt solar farm near Coldwater, Michigan, paid for by Ford. [31]

The $194 million Cold Creek farm can power about 23,000 to 25,000 homes. [31] It is the first of several DTE projects meant to supply Ford's Michigan factories. [31]

Ford agreed in 2022 to buy up to 650 megawatts of renewable power. [31]

Why it matters

Ford now aims to build every vehicle it makes in Michigan on carbon-free electricity by the end of 2027. [31]

Why it matters

The goal was 2025 when the deal was signed, and the new announcement does not say why it moved. [31]

Spain tests solar panels on the sea

Swipe up for the story ↑Scroll down for the story ↓

Spain's first test-scale floating solar plant at sea has started tests in the Port of Valencia. [32] Its two 500-kilowatt platforms were built by BlueNewables with Naturgy, a Spanish energy company. [32]

They are named after Paiporta and Catarroja, two towns hit by the 2024 DANA storm. [32] The trial runs for two years, paid for with Spanish and EU recovery money. [32]

Why it matters

Floating panels can go where land is scarce or the grid is crowded, such as ports and islands. [32]

Why it matters

The test will show what they cost to run and repair in salt water. [32]

Italy runs a hydrogen plant on solar

Swipe up for the story ↑Scroll down for the story ↓

SIAD, an Italian chemical and engineering group, has opened a 2-megawatt plant near Caserta that splits water into hydrogen. [33] It runs only on a 2.37-megawatt solar field and a battery. [33]

The hydrogen will be compressed and sold to factories. [33] The project cost more than 12 million euros, 8 million of it from Italy's recovery fund. [33]

Why it matters

SIAD says the hydrogen is for industrial uses where running directly on electricity is hard. [33] Two thirds of the cost came from public money. [33]

A gas company pays for ground heat

Swipe up for the story ↑Scroll down for the story ↓

Vermont Gas, a gas utility, will pay for and own the underground pipes that heat and cool new affordable homes at Riggs Meadow in Hinesburg, Vermont. [34]

Ground-source heat pumps move heat between the ground and the buildings through those pipes. [34]

The ground stays at a steady temperature, so the system works in cold winters and hot summers. [34]

The development has 44 homes for people on low and moderate incomes, and 36 of them will use ground heat. [34]

Why it matters

The upfront cost of the pipes usually keeps affordable housing from using ground heat. [34]

Why it matters

For the gas company, owning the pipes is a way to offer heating and cooling that run on electricity. [34]

Good news

In Hinesburg, Vermont, 36 homes for people on low and moderate incomes will be heated and cooled from the ground, and the gas company is paying for the pipes.

A food pantry gets storm-proof power

Swipe up for the story ↑Scroll down for the story ↓

Beacon of Hope, a food pantry in Marshall, North Carolina, has installed 56 solar panels and three batteries. [35]

They can run its lights, internet, heating, cooling and fridges when the grid fails. [35]

The $100,000 system cost the pantry nothing: it came from a $5 million state programme for 24 microgrids, small grids that can run on their own. [35]

Hurricane Helene's floods nearly wiped out Marshall's downtown two years ago. [35]

Why it matters

The pantry feeds 1,700 families a month and it kept its power through Helene. [35]

Why it matters

Bigger microgrids are stuck because they need foreign parts that federal funding rules do not allow without a waiver. [35]

Good news

A food pantry in Marshall, North Carolina, that feeds 1,700 families a month now has solar panels and batteries to keep its fridges and lights on in the next storm. The $100,000 system cost the pantry nothing.

The Holei Sea Arch, a 27-metre lava-rock arch on Hawaii's Big Island, has fallen into the Pacific, the US National Park Service said. [36] It formed about 550 years ago. [36]

It was standing on 23 September and gone by 27 September, and probably fell while the park was closed for Tropical Storm Nolo. [36]

Earthquakes during the 2018 Kilauea eruption had damaged the cliffs. [36]

Why it matters

The park service warned in 2021 that the arch would fall. [36] It says new arches will form as the cliff slowly moves inland. [36]

US Coast Guard stops fuel bound for Cuba

Swipe up for the story ↑Scroll down for the story ↓

The US Coast Guard said on Friday it had stopped a cargo ship, the Grace, carrying fuel to Cuba on 5 September. [37]

It said the ship used tricks to hide where it was going, and that it seized a smaller boat earlier this summer. [37]

The Trump administration is enforcing a fuel blockade meant to force political change in Cuba. [37] The Coast Guard said only that intelligence showed the fuel was bound there. [37]

Why it matters

The New York Times says the blockade has helped cripple Cuba's economy and caused wide suffering among its 8 to 10 million people. [37]

Why it matters

The Times says the US is now using the military, not just tariff threats, to cut off Cuba's fuel. [37]

Prospectors stake claims in Bears Ears

Swipe up for the story ↑Scroll down for the story ↓

Prospectors filed 16 mining claims on 11 September, the first day that land cut from Bears Ears National Monument in Utah reopened. [38]

President Trump shrank the monument by about 90% in July. [38] Thirteen claims came from Kimmerle Mining, a family firm in Moab, and the claimants appear interested in uranium. [38]

Bears Ears was created in 2016 to protect 1.35 million acres. [38]

Why it matters

The July order also disbanded the tribal commission that helped run the monument. [38]

Why it matters

A claim is only the first step towards a mine, and environmental groups expect more claims to follow. [38]

Crushed rock on land shows up in a stream

Swipe up for the story ↑Scroll down for the story ↓

Scientists spread crushed basalt rock on land draining into a small stream, and the stream's water changed within weeks, a study in a Nature journal reports. [39]

Spreading rock dust, called enhanced weathering, is a way to pull carbon dioxide out of the air. [39]

Over two years, about a tenth of the rock's possible carbon removal flowed out in the stream as dissolved carbon. [39] The effect was strongest in summer and autumn. [39]

Why it matters

Carbon carried to the sea in this form can stay locked away for tens of thousands of years, the authors note. [39]

Why it matters

So measuring what leaves in streams is part of checking how much carbon the method really removes. [39]

Solar panels shade vines in Puglia

Researchers at the University of Bari grew grapevines under solar panels in Puglia, a hot, dry part of southern Italy. [40]

Average weight of a grape bunch in the Puglia trial. The test was in a hot, dry place only.

Under heavy shade, grape bunches averaged 164.9 grams, against 65.4 grams in full sun. [40]

The shaded grapes were less sugary: they scored 22.9 on the Brix scale of sugar, against 25.8 in full sun. [40]

Earlier work in cooler northern Italy found vines did better outside the panels. [40]

Why it matters

Panels can shield crops from extreme heat where summers are hot and dry, the lead researcher says. [40] He warns the result does not carry over to wetter places. [40]

Hybrid coffee beats pure Arabica

Swipe up for the story ↑Scroll down for the story ↓

A trial of 32 coffee varieties at 30 sites in 17 countries found that varieties bred with genes from other coffee plants beat pure Arabica, a study in a Nature journal reports. [41]

They gave more coffee and suffered less from leaf rust, a fungus disease. [41] Two hybrids, H1 Centroamericano and EC16, did best overall. [41]

Coffee is grown on about 12.5 million farms, most of them small family plots. [41]

Why it matters

How steady each variety's harvest was depended on local temperatures, and leaf rust depended on heat, rain and humidity together. [41]

Why it matters

The authors say this gives a basis for choosing which coffee to plant as the climate changes. [41]

Denser city districts, less carbon per person

Swipe up for the story ↑Scroll down for the story ↓

A study of 278 Chinese cities from 2013 to 2019 found that where homes and shops are packed more densely, each person emits slightly less carbon dioxide. [42]

A 1% rise in the density of people in those districts went with a 0.09% fall in carbon per person. [42]

The authors left factory land out of the density count, which earlier studies had mixed in. [42]

Why it matters

The authors say building compact districts for homes and shops can help China's cities cut carbon. [42] Separating factory land from homes was what made the link clear in their data. [42]

That's the whole Climate day.
