Up to 2cm a month: Nasa keeps track as Mexico City sinks into the ground

Powerful radar system is providing new data on city’s subsidence, which experts hope will draw more attention to it

Walking into Mexico City’s sprawling central Zócalo is a dizzying experience. At one end of the plaza, the capital’s cathedral, with its soaring spires, slumps in one direction. An attached church, known as the Metropolitan Sanctuary, tilts in the other. The nearby National Palace also seems off-kilter.

The teetering of many of the capital’s historic buildings is the most visible sign of a phenomenon that has been ongoing for more than a century: Mexico City is sinking at an alarming rate.

Fertiliser shortages will have ‘dramatic’ effect on global food prices, warns farming boss

Powerful property and farming firm Grosvenor Group says knock-on effect of Iran war could arrive next year

Fertiliser shortages caused by the Iran war have driven up costs for UK farmers by up to 70% and will have a “dramatic” impact on food prices globally next year, according to one of Britain’s most powerful property and farming companies.

Mark Preston, executive trustee of the 349-year-old Grosvenor Group, controlled by the Duke of Westminster, said fertiliser “was already quite expensive” before the 50% to 70% surge in prices since the start of the Iran war in late February.

Alaska’s 2025 mega tsunami highlights risk to cruise lines as glaciers retreat

Researchers say 481-metre wave in fjord was triggered by rockslide linked to climate crisis

A mega tsunami in Alaska last year in a fjord visited by cruise ships is a stark warning of the risks of coastal rockslides and glacier retreat fueled by the climate crisis, a new study warns.

Scientists recorded the world’s second-tallest tsunami after it struck the Tracy Arm fjord in south-east Alaska last August after a massive rockslide around the toe of a glacier. The tsunami reached 481 metres (1,578ft) in height; by comparison the Eiffel Tower is 330 metres (1082ft).

EU trade deal could force UK to restrict use of weedkiller linked to cancer

Glyphosate is currently sprayed on cereal and pulse crops to dessicate them and make them easier to harvest

A new trade deal with the EU could lead to restrictions on the use of the controversial weedkiller glyphosate on UK food crops.

The full-spectrum herbicide, which kills almost every plant it touches, is often sprayed on wheat, oats and other cereal and pulse crops shortly before harvest to desiccate them and make them easier to handle.

Norwegian fish farms polluting fjords with waste likened to ‘raw sewage of millions of people’

Exclusive: ‘Fish sludge’ in coastal waters now has nutrient levels equivalent to those in untreated effluent of country the size of Australia, report finds

Norwegian fish farms are filling fjords and other coastal waters with nutrient pollution equivalent to the raw sewage of tens of millions of people each year, a report has found.

Norway is the largest farmed salmon producer in the world, and nutrients in fish feed are excreted directly into coastal waters. Analysis from the Sunstone Institute found that Norwegian aquaculture released 75,000 tonnes of nitrogen, 13,000 tonnes of phosphorus and 360,000 tonnes of organic carbon in 2025.

Weather tracker: Cold spells in Greece and Turkey, and storms in Bangladesh

High winds have hit the South Aegean and heavy rain has fallen in Turkey, but Central Europe has felt summer heat

Greece and Turkey have found themselves in the grip of a late-season cold spell this weekend. Conditions will persist over the next few days as an area of low pressure situated over Turkey is pulling in colder, moisture-laden air from the north-east via the Black Sea; this meteorological set up has suppressed temperatures well below where they should be for the time of year. Away from the Mediterranean coast, much of Turkey struggled to reach double figures, which is around 10C below the average, while Greece saw a similar chill. In Athens, temperatures only crept into the low teens Celsius, a far cry from the mid-20s typically expected in early May.

But they haven’t just faced colder temperatures. Greece had gale force winds whipping through the islands in the South Aegean – gusting at around 60mph on Sunday evening and the unsettled weather has brought a surge of heavy rain to Turkey. The Central Anatolia region of Turkey would normally see about 50mm of rainfall across the entire month of May, but on Sunday had already seen many areas pick up half that total in just 24 hours. With colder air in place, higher elevations have even seen a return to winter, with up to 30cm of fresh snow forecast across the Anti-Taurus Mountains on Monday and Tuesday. In Ankara, temperatures on Monday were expected to peak at just 7C – nearly 14C below average – before slowly edging back towards normal by the weekend.

‘They don’t belong in our environment’: US vineyards battle spotted lanternflies as invasive insects spread

From Virginia to New York, the bugs drain vines, cut yields and leave growers resorting to one simple fix: squash them

Around grape harvest time about three years ago, an employee at Zephaniah Farm Vineyard in Leesburg, Virginia, noticed bugs, about 1in long with gray and black wings and a bright red underwing, atop some trees.

While the insects were pretty, they were there for the grapevines and not welcome guests at the vineyard, which sits atop a farm that the Zephaniah family has run since 1949.

Octopus Energy boss: some people would accept blackouts if bills cut

Greg Jackson argues against costly investments in UK’s power grid that are adding to household bills

The boss of the UK’s biggest energy supplier has suggested that some households would accept an occasional electricity blackout in exchange for much lower energy bills.

A year on from Europe’s largest power outage – which left tens of millions of people in Spain and Portugal without trains, metros, traffic lights, ATMs, phone connections and internet access – the chief executive of Octopus Energy argued against costly investments in the UK’s power grid that are adding to household bills.

‘Don’t fall!’: foil boarders describe hair-raising shark chase caught on video off California coast

Foil boarders were pursued by shark – likely a great white – off Santa Barbara before it lost interest and swam away

Ron Takeda and Tavis Boise were a few miles off the coast of Santa Barbara when they noticed the large mass trailing behind them.

“Tavis, is it a dolphin?” asked Takeda as he stood on his foil board, a specialized form of surfing, propelling himself through the waves. Boise, who was filming their run, recognized the question as an ominous sign – the veteran surfers are familiar enough with dolphins that Takeda should have recognized one immediately.

US supreme court weighs blocking lawsuits against Roundup makers alleging weedkiller causes cancer

Case centers on glyphosate, pesticide used in Roundup and other products that has been linked to cancer in some studies

Members of the US supreme court peppered lawyers for the former Monsanto Company with a barrage of questions over pesticide regulation on Monday, wrestling over whether federal law preempts state actions that permit consumers to sue companies for failing to warn of product risks such as cancer.

The case, Monsanto v Durnell, centers on glyphosate – a weedkilling chemical used in the popular Roundup brand and numerous other herbicide products sold by the former Monsanto company, which is now owned by Germany’s Bayer.

Renewable energy will boost national security and protect UK from sabotage, minister says

Widely dispersed wind farms and solar panels are harder to target than fossil fuel power stations, Michael Shanks says

Renewable energy will boost the UK’s national security and make the country more resilient against potential aggression or sabotage, the government’s energy minister has said.

Michael Shanks said widely dispersed wind farms and solar panels were much harder to target than large-scale fossil fuel power stations. They are also not vulnerable to supply shocks, such as the current oil crisis caused by the US-Israel war on Iran and the soaring gas prices that followed Russia’s invasion of Ukraine in 2022.

What counts as the woods? Judge axes Nova Scotia’s ban that defied ‘commonsense definitions’

The court sided with a Canadian hiker who deliberately challenged the order imposed to curb spread of wildfires

As wildfires raged across Nova Scotia last summer, the Canadian province made a simple plea to residents: stay away from the woods.

As the situation deteriorated, authorities turned the request into a prohibition: anyone caught hiking under the shade of the forest canopy faced a C$25,000 fine – a figure more than half the average worker’s yearly salary.

Officials hugely underestimated impact of AI datacentres on UK carbon emissions

Revised figures increase fears about how the energy-intensive sites could worsen the climate emergency

The UK government vastly underestimated the climate impact of artificial intelligence, it has emerged, after officials raised their estimate of carbon emissions from the technology by a factor of more than 100.

According to new data quietly published this week, energy use by AI datacentres in the UK could cause the emission of up to 123m tonnes of carbon dioxide (MtCO₂) – about as much as generated by 2.7 million people – over the next 10 years.
