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.

Exclusive: 80% of Welsh dairy farms inspected, 69% of English ones, 60% in Scotland and 50% in Northern Ireland breaching regulations

The majority of UK dairy farms are breaking pollution rules, with vast amounts of cow manure being spilled into rivers.

When animal waste enters the river, it causes a buildup of the nutrients found in the effluent, such as nitrates and phosphates. These cause algal blooms, which deplete the waterway of oxygen and block sunlight, choking fish and other aquatic life.

Noreen and Antonia, born last May, are among first cloned offspring of a native endangered species in the North America

Two more black-footed ferrets have been successfully cloned in an attempt to save the endangered species, the US Fish and Wildlife Service (USFWS) announced.

The national agency shared news about the births of ferrets Noreen and Antonia, who were both born last May.

Scientists estimate Vasuki indicus was up to 15m long, weighed a tonne and would have constricted its prey

Fossil vertebrae unearthed in a mine in western India are the remains of one of the largest snakes that ever lived, a monster estimated at up to 15 metres in length – longer than a T rex.

Scientists have recovered 27 vertebrae from the snake, including a few still in the same position as they would have been when the reptile was alive. They said the snake, which they named Vasuki indicus, would have looked like a large python and would not have been venomous.

Bill would stop private investors, including hedge funds, farmers and municipalities, from profiting off water scarcity

With private investors poised to profit from water scarcity in the west, US senator Elizabeth Warren and representative Ro Khanna are pursuing a bill to prohibit the trading of water as a commodity.

The lawmakers will introduce the bill on Thursday afternoon, the Guardian has learned. “Water is not a commodity for the rich and powerful to profit off of,” said Warren, the progressive Democrat from Massachusetts. “Representative Khanna and I are standing up to protect water from Wall Street speculation and ensure one of our most essential resources isn’t auctioned off to the highest bidder.”

A new analysis by Consumer Reports shows that pesticides have contaminated the US fruit and vegetable supply – even some organics

• What’s safe to eat? Here is the pesticide risk level for each fruit and vegetable

Watermelon, green beans and bell peppers are among the many common fruits and vegetables found in US supermarkets that contain potentially unsafe levels of pesticides, according to an analysis published today by Consumer Reports.

The new report – which analyzed seven years of US Department of Agriculture data on commonly eaten fruits and vegetables – offers one of the most comprehensive evaluations to date of pesticides found in US produce. The data was based on nearly 30,000 fruit and vegetable samples, including fresh, frozen, canned and organic, collected from supermarkets by the USDA as part of routine pesticide testing. Consumer Reports built a massive database to analyze the data – and scored different foods to provide actionable recommendations to help consumers shop and eat with less risk.

Even organic produce can contain unhealthy amounts of pesticide – see which fruits and vegetables rank best and worst

After reviewing the results of thousands of tests on fruits and vegetables, Consumer Reports has found unhealthy levels of pesticides in about 20% of US produce.

This chart, in alphabetical order, shows the risk from pesticides in conventional and organic produce, as well as whether the fruits and vegetables are domestically grown or imported. Consumer Reports “recommends those rated as very low, low or moderate risk. When possible, replace a food rated high or very high with a lower-risk one, or choose organic. Keep in mind that the risk comes from repeated servings over time.”
