Historic hearing will receive submissions from people whose human rights have been affected by climate change

Julian Medina comes from a long line of fishers in the north of Colombia’s Gulf of Morrosquillo who use small-scale and often traditional methods to catch species such as mackerel, tuna and cojinúa.

Medina went into business as a young man but was drawn back to his roots, and ended up leading a fishing organisation. For years he has campaigned against the encroachment of fossil fuel companies, pollution and overfishing, which are destroying the gulf’s delicate ecosystem and people’s livelihoods.

Overseas firms sending key goods to UK would have to show they were paying for emissions or face CBAM

Ministers are under growing pressure to firm up plans for a green levy on imports to the UK before the general election campaign.

The government is consulting on plans to introduce a carbon border adjustment mechanism (CBAM) from 2027. Under the system, overseas companies wishing to export key goods to the UK would have to show they were paying for their carbon emissions, or face a levy equivalent to the price paid for carbon by UK manufacturers.

Proposed ‘fast-track’ law could see conservation concerns ignored and projects once rejected for environmental reasons given the green light

New Zealand’s parliament is considering a law that would allow major development projects to bypass environmental approvals – and that should be a cause for extreme alarm.

The proposed Fast-track Approvals Bill emerged from the coalition agreements that enabled a centre-right government to form after last year’s election.

Nicola Wheen and Andrew Geddis are professors of law at the University of Otago.

Europeans are dying from hot weather 30% more than they did two decades ago, report finds

Scorching weather has baked Europe in more days of “extreme heat stress” than its scientists have ever seen.

Heat-trapping pollutants that clog the atmosphere helped push temperatures in Europe last year to the highest or second-highest levels ever recorded, according to the EU’s Earth-watching service Copernicus and the World Meteorological Organization (WMO).

From right to roam to anger over polluted rivers, a new breed of activists is pushing back against environmental destruction

Something very interesting is happening in the UK, to do with nature, the expanses of land we think of as the countryside, and where all those things sit in our collective consciousness. The change has probably been quietly afoot for 20 or 30 years. Now, it suddenly seems to be blurring over from the cultural sphere into our politics, with one obvious consequence – the belated entry into the national conversation of issues that have long been pushed to the margins, from land access and ownership to the shocking condition of our rivers.

The prevailing British attitude to nature has long been in an equally messed-up state. From the 1600s onwards, endless enclosure acts pushed people off the land and seeded the idea of the countryside as somewhere largely out of bounds. Britain’s rapid industrialisation only accelerated the process. And despite occasional cultural and political tilts in the opposite direction – the bucolic visions of the 18th- and 19th-century Romantics, the mass trespass movement of the 1930s – most of us now show the signs of that long story of loss and estrangement.

Fly away home… You can have too much of a good thing

‘Look, a ladybird!’ This was how it started. My family were staying the night in a bed and breakfast near friends in rural England – we had driven through a landscape the colour of butter to park under a hillside upon which the shadows of clouds passed like curtains closing. I was medicated, pleasantly, can you tell, in a hangover from the most painful migraine of my life, and the clouds reminded me of the visual aura that flickers across your vision just before the headache begins. We put our bag on a chair, and there, inside the window frame, was a ladybird. And then, look, there was another one. The children gathered, by the window ready to be enchanted.

A group of ladybirds is called a “loveliness”, which, to me, sounds suspicious. Sounds problematic even. As if they have named themselves. A “conspiracy” of lemurs, that’s a good one, implies darkness, intelligence. A “bloat” of hippos, relatable. A “destruction” of wild cats, you’ve got a whole story there, beginning, middle, end. But a “loveliness”, please. Perhaps it’s my own must-work-on-it tendency towards tall poppy syndrome, perhaps I am inordinately disgusted by the ladybirds’ cloying self-satisfaction – I find the term embarrassing. However, there it was, a loveliness, crawling all over the window frame.

BBC nature presenter delivers eulogy at protest aimed at ‘scaring people a bit’ about the loss of biodiversity in the UK

The BBC nature presenter Chris Packham has joined hundreds of environmental activists in a mock funeral procession for nature to spotlight biodiversity loss in the UK.

The procession aimed to sound “code red for nature” and highlight the UK’s position as “one of the most nature-depleted countries in the world”, organisers said. It was planned to coincide closely with Earth Day on 22 April.

Chris Stark, head of the Climate Change Committee, says Tories’ decision to dilute key green policies has had huge diplomatic impact

Rishi Sunak has given up Britain’s reputation as a world leader in the fight against the climate crisis and has “set us back” by failing to prioritise the issue in the way his predecessors in No 10 did, the government’s green adviser has warned.

Chris Stark, the outgoing head of the Climate Change Committee (CCC), said that the prime minister had “clearly not” championed the issue following a high-profile speech last year in which he made a significant U-turn on the government’s climate commitments. The criticism comes after Sunak was accused of trying to avoid scrutiny of Britain’s climate policies by failing to appoint a new chair of the CCC.

Keir Starmer must learn from the Tories’ failures and ensure green projects are well planned and resourced

In the energetic pursuit of net zero, billions of pounds could be squandered needlessly. That’s the lesson from countries as diverse as Italy, the US and UK, where the rush to subsidise green projects suggests vast sums are at risk. Worse, they could be lining the pockets of multinational businesses and City financiers.

In the UK, 14 years of austerity has left the public sector struggling to make coherent, strategic decisions. When a decision is finally made, it is a panic measure that quickly unravels. The fallout could be that voters become disenchanted with green tech, especially if the dash for net zero leads to higher taxes and higher borrowing while early adopters unwittingly pay for costly mistakes.

Recordings of healthy fish are being transmitted to attract heat-tolerant larvae back to degraded reefs in the Maldives

An underwater experiment to restore coral reefs using a combination of “coral IVF” and recordings of fish noises could offer a “beacon of hope” to scientists who fear the fragile ecosystem is on the brink of collapse.

The experiment – a global collaboration between two teams of scientists who developed their innovative coral-saving techniques independently – has the potential to significantly increase the likelihood that coral will repopulate degraded reefs, they claim.

Exclusive: Whistleblowers point to broader sewage scandal, with wastewater systems manipulated to divert sewage

Whistleblowers say UK water companies are knowingly failing to treat legally required amounts of sewage, and that some treatment works are manipulating wastewater systems to divert raw sewage away from the works and into rivers and seas.

It is well known that water companies are dumping large volumes of raw sewage into rivers and seas from storm overflows but an investigation by the Guardian and Watershed Investigations reveals that the industry’s “dirty secret” is bigger, broader and deeply systemic.

Video shows trees and shrubs along Western Australia's south-west coastline turning brown after Perth recorded it hottest and driest six months since records began. There were similar scenes in the state's south-west eucalypt forests in 2010 and 2011 – a major die-back event that prompted more than a dozen studies. Drought-hit forests were hit by fire years later

Experts celebrate discovery of secretive and endangered Australasian bittern in recently restored wetlands

The “bunyip bird” – named after a mythological river-lurking, human-eating monster – is as elusive as its namesake. Also known as the Australasian bittern, it is heard more often than it is seen.

It means that when bittern expert Geoff Shannon discovered the bird at Tasmania’s recently restored Lagoon of Islands – the first time it had been seen there in 40 years – it was a “very special moment”.

A couple of weeks ago, Joe Fontaine stood in the middle of one of Western Australia’s eucalypt forests on another hot and dry day that was stripped of the usually raucous backing-track of bird calls.

“I could hear this scratching-crunching noise coming from the trees,” says Fontaine, a forest ecologist at Perth’s Murdoch University.

Superfund law requires industries responsible for PFOA and PFOS contamination in water or soil to pay for cleanup

The Environmental Protection Agency on Friday designated two forever chemicals that have been used in cookware, carpets and firefighting foams as hazardous substances, an action intended to ensure quicker cleanup of the toxic compounds and require industries and others responsible for contamination to pay for their removal.

Designation as a hazardous substance under the Superfund law does not ban the chemicals, known as PFOA and PFOS. But it requires that release of the chemicals into soil or water be reported to federal, state or tribal officials if it meets or exceeds certain levels. The EPA then may require cleanups to protect public health and recover costs that can reach tens of millions of dollars.

Research into release of ‘forever chemicals’ raises concerns about contamination and human exposure along world’s coastlines

Ocean waves crashing on the world’s shores emit more PFAS into the air than the world’s industrial polluters, new research has found, raising concerns about environmental contamination and human exposure along coastlines.

The study measured levels of PFAS released from the bubbles that burst when waves crash, spraying aerosols into the air. It found sea spray levels were hundreds of thousands times higher than levels in the water.

Exclusive: Study released at Cop28 misused research to underestimate impact of cutting meat eating, say academics

A flagship UN report on livestock emissions is facing calls for retraction from two key experts it cited who say that the paper “seriously distorted” their work.

The UN Food and Agriculture Organization (FAO) misused their research to underestimate the potential of reduced meat intake to cut agricultural emissions, according to a letter sent to the FAO by the two academics, which the Guardian has seen.

Analysis of 60o gardens shows wilder lawns feed caterpillars and create breeding habitat

Good news for lazy gardeners: one labour-saving tweak could almost double the number of butterflies in your garden, according to a new scientific study – let the grass grow long.

In recent years nature lovers have been extolling the benefits of relaxed lawn maintenance with the growing popularity of the #NoMowMay campaign. Now an analysis of six years of butterfly sightings across 600 British gardens has provided the first scientific evidence that wilder lawns boost butterfly numbers.

Marcus Decker dared to protest on climate and was punished. Now he could be deported. Is that a humane democracy?

When the traditional ruling class was obliged to concede to demands for democracy, it gave away as little as possible. We could vote, but it ensured that crucial elements of the old system remained in place: the House of Lords, the first-past-the-post electoral system, prerogative powers and Henry VIII clauses, and above all a legal system massively and blatantly biased towards owners of property.

In combination, these elements ensured that the system remained predisposed to elite rule, even while it pretended the people were in charge. The portcullis excluding us from power has never been properly lifted since the Norman conquest. The relationship between rulers and ruled remains, in effect, a relationship between occupier and occupied.
