Ocean-inspired artworks created using kelp-based pigment will be sold to raise funds for conservationLast year in early summer, Alex Glasgow could be seen hauling up a long string of orangey-black seaweed on to the barge of his water farm, located off the west coast of Scotland near Skye. Growing on the farm was what Glasgow described as perhaps the quickest-growing biomass on the planet": seaweed.The weed from Glasgow's farm, KelpCrofters, is used in everything from soil fertiliser to artisanal soaps to glass-making and is part of a burgeoning industry - not just in Scotland, but around the world.

As temperatures rise and countries back off their decarbonization efforts, we must confront a reality central banks can't correctInflation is, at base, a tax on consumption - and it hits the poor the hardest, since they consume more of their incomes and the rich consume less.That's one reason for concern over Donald Trump's tariffs, which will disproportionately affect the poor. When the 90-day pause on the tariffs expires, it is reasonable to expect prices to rise, and by a lot.Mark Blyth is a political economist and professor at Brown University. Nicolo Fraccaroli is a visiting scholar at Brown University. The views expressed here are the writers' own and not their institutions' Continue reading...

The Guardian is joining forces with dozens of newsrooms around the world to launch a year-long exploration of the silent majority' of people who want to fight climate changeThe Guardian US is launching a year-long collaborative reporting project that seeks to explore a pivotal but little-known fact about the climate crisis: the overwhelming majority of the world's people want their governments to take stronger action.The 89 Percent Project is a partnership between the Guardian US, Covering Climate Now, Agence France-Presse and dozens of other newsrooms across the globe. The collaboration builds on a slate of recent scientific studies finding that between 80-89% of the world's population want stronger climate action. This overwhelming global majority, however, does not realize that they are a majority; most think their fellow citizens don't agree. Experts agree breaking this spiral of silence" could be pivotal to spurring critical climate action. Continue reading...

Potential danger to humans and wildlife from harmful pesticide discovered in fish at 10 times safety limitResidues of the insecticide DDT have been found to persist at alarming rates" in trout even after 70 years, potentially posing a significant danger to humans and wildlife that eat the fish, research has found.Dichlorodiphenyltrichloroethane, known as DDT, was used on forested land in New Brunswick, Canada, from 1952 to 1968. The researchers found traces of it remained in brook trout in some lakes, often at levels 10 times higher than the recommended safety threshold for wildlife. Continue reading...

Island country deals with drought and hurricane damage as it pushes for reparations from countries that benefited from slaveryWhen category 4 Hurricane Beryl hit the Caribbean last June, the three-island nation of Grenada bore the brunt of its wrath. At the time, the country's prime minister, Dickon Mitchell, described the destruction as almost Armageddon-like". On the small island of Carriacou, it was estimated by officials that more than 90% of the buildings were damaged or destroyed. Agriculture and infrastructure for electricity and communication were almost completely wiped out.Nearly a year on, there are some signs of recovery and rebuilding, but hollowed-out buildings, roofless houses and charred, dying mangroves tell the story of a community that is still coming to grips with the devastation.

Cuts to science, environmental and safety agencies are a rejection of hard-won knowledge gained from studying the disaster that occurred 15 years agoLast month, I joined nearly 500 former and current employees of National Geographic, where I was executive vice-president and chief science and exploration officer for 17 years, urging the institution to take a public stance against the Trump administration's reckless attacks on science. Our letter pointed out that the programs being dismantled are imperative for the success of our country's economy and are the foundation of our progress and wellbeing. They make us safer, stronger and more prosperous." We warned that gutting them is a recipe for disaster.In the face of this danger, none of us can remain silent.Terry Garcia was National Geographic's executive vice-president and chief science and exploration officer for 17 years.

The energy secretary has accused Reform UK's leader of peddling dangerous falsehoods about renewable power

If green policy is going to survive the culture wars, it needs a new pitch - cleaner air, cheaper bills and healthier citiesFor a decade, green activists in Britain have been congratulating themselves on their luck. Unlike in many countries in Europe, where motorists, farmers and rightwing groups have been driving anti-climate action, the UK has long enjoyed a comfortable political consensus on the subject. But conditions for a greenlash are assembling.Most Britons still say they support climate efforts, but the price of decarbonising may at last be about to hit our wallets. Meanwhile, the Conservative party has come a long way since it sported a little green oak tree as its logo. Last month, Kemi Badenoch declared a full culture war against net zero, which she said couldn't be achieved without a serious drop in our living standards or by bankrupting us".Do you have an opinion on the issues raised in this article?

In an exclusive extract from Friederike Otto's new book, she says climate disasters result from inequality as well as fossil fuelMy research as a climate scientist is in attribution science. Together with my team, I analyse extreme weather events and answer the questions of whether, and to what extent, human-induced climate change has altered their frequency, intensity and duration.When I first began my research, most scientists claimed that these questions couldn't be answered. There were technical reasons for this: for a long time, researchers had no weather models capable of mapping all climate-related processes in sufficient detail. But there were other reasons that had less to do with the research itself. Continue reading...

Thousands go to hospital with respiratory problems after massive dust cloud blows in from Saudi ArabiaIraq was hit by its most severe sandstorm of 2025 this week, turning skies from blue to an orange haze. Visibility dropped to less than half a mile, causing travel disruptions, with two major airports halting flights, and streets in Basra, the largest city in southern Iraq, deserted. Respiratory problems sent thousands to hospital. The storm also affected Kuwait, where wind gusts exceeded 50mph, and visibility in some areas was diminished to zero.This massive dust cloud originated in Saudi Arabia before being blown into Iraq. While dust storms are common in Iraq, the climate crisis is expected to intensify them across the region in the future, fuelled by desertification in Saudi Arabia and Syria. Continue reading...

Exclusive: Henry Dimbleby joins farmers in voicing fears of lower standards and a poor deal for British food producersBritain's rural communities could be destroyed", the former government food tsar has said, if ministers sign a US trade deal that undercuts British farming standards.Ministers are working on a new trade deal with the US, after previous post-Brexit attempts stalled. Unpopular agreements signed at the time with Australia and New Zealand featured tariff-free access to beef and lamb and were accused of undercutting UK farmers, who are governed by higher welfare standards than their counterparts. Australia, in a trade deal signed by Liz Truss in late 2021 that came into effect in 2023, was given bespoke sanitary and phytosanitary (SPS) standards aimed to not be more trade-restrictive than necessary to protect human life and health".

Liberals in the US make up about 15% of the prepping scene and their numbers are growing. Their fears differ from their better-known rightwing counterparts - as do their methodsOne afternoon in February, hoping to survive the apocalypse or at least avoid finding myself among its earliest victims, I logged on to an online course entitled Ruggedize Your Life: The Basics.Some of my classmates had activated their cameras. I scrolled through the little windows, noting the alarmed faces, downcast in cold laptop light. There were dozens of us on the call, including a geophysicist, an actor, a retired financial adviser and a civil engineer. We all looked worried, and rightly so. The issue formerly known as climate change was now a polycrisis called climate collapse. H1N1 was busily jumping from birds to cows to people. And with each passing day, as Donald Trump went about gleefully dismantling state capacity, the promise of a competent government response to the next hurricane, wildfire, flood, pandemic, drought, mudslide, heatwave, financial meltdown, hailstorm or other calamity receded further from view.

Salmon is often marketed as the sustainable, healthy and eco-friendly protein choice. But what you may not realise is that most of the salmon you buy is farmed, especially if you live in the UK, because Scottish salmon producers are no longer required to tell you.Josh Toussaint-Strauss finds out why it is important for consumers to know where their salmon comes from, and examines the gap between the marketing of farmed salmon and the reality for our health, the environmental and animal welfare

From the rock sea-spurrey, which appears to grow out of solid rock, to the slender centaury that lives on a landslip, these plants exist where they do for good reasonI first encountered coastal wildflowers when I was 11. I was visiting my grandmother's friend in Devon and a lady said: Here, dear," and dug up a clump of Warren crocuses - a rare plant that, at the time, was only thought to grow in the seaside resort of Dawlish Warren. She gave them to me to grow in my garden at home. But of course they didn't grow away from the sea.That was when I realised there was something special about coastal wildflowers. They fascinate me because, as well as being beautiful flowers, they often grow in tough locations. Take the rock sea-spurrey: a delicate little plant that appears to grow out of solid rock, such as a crevice in a cliff base. It can put up with being splashed with sea spray and baked by the summer sun. And yet it seems to thrive in that difficult, harsh environment. Continue reading...

Up and down the country, volunteers are coming together to plant more of these nature-rich reservesThe 30-metre ridge runs across the moor near Yar Tor on Dartmoor, one of several faint lines that crisscross the land like aeroplane contrails. Although the open moorland looks wild, we are standing on some of the UK's oldest farmland. These ridges, called reaves, are the ghosts of farming's most wildlife-rich legacy: hedges.These reaves sadly have no function today other than to delight us. Or some of us," says ecologist Rob Wolton. But Dartmoor's reaves are the skeletons upon which more recent hedges were built: hundreds of thousands of miles of them. After Ireland, the UK is believed to be the most hedge-dense country in the world, and Wolton says the majority of them are more than 280 years old. Recent laser scanning shows England has enough hedges to wrap around the world almost 10 times. They are, by far, the country's biggest nature reserve, which is why community groups, farmers and charities are rallying together to plant hedges of the future that will offer the same support to wildlife as the ancient hedges of the past.

Previous estimates based on prints and sightings put the bear population at fewer than 8,000. Continue reading...

Researchers say urgent action needed to inform people about risks of heatwave temperatures and adapt homesThe number of UK homes overheating in summer quadrupled to 80% over the past decade, according to a study, with experts calling the situation a crisis.Heat already kills thousands of people each year in the UK and the toll will rise as the climate crisis intensifies. Urgent action is needed both to inform people on how to cope with high temperatures and to adapt homes, which are largely designed to keep heat in during the winter, the researchers said.

Exclusive: Ancient oaks as precious as stately homes' could receive stronger legal safeguards under new proposalsAncient and culturally important trees in England could be given legal protections under plans set out in a UK government-commissioned report.Sentencing guidelines would be changed so those who destroy important trees would face tougher criminal penalties. Additionally, a database of such trees would be drawn up and they could be given automatic protections, with the current system of tree preservation orders strengthened to accommodate this.In 2020, the 300-year-old Hunningham Oak near Leamington was felled to make way for infrastructure projects.In 2021, the Happy Man tree in Hackney, which the previous year had won the Woodland Trust's tree of the year contest, was felled to make way for housing development.In 2022, a 600-year-old oak was felled in Bretton, Peterborough, which reportedly caused structural damage to nearby property.In 2023, 16 ancient lime trees on The Walks in Wellingborough, Northamptonshire, were felled to make way for a dual carriageway.
