Through the G20, Brazil’s president is challenging the dominance of the richest countries. This year will be a huge test of his strategy

The world stage often seems sepia-toned, dominated by the dusty international structures of the post-second world war era, favouring the world’s richest countries. However, it is increasingly clear that this setup isn’t sufficient to respond to the interests of the global south, including combating climate breakdown and expanding economic development.

Recognising this mismatch, Brazil under President Luiz Inácio Lula da Silva has positioned itself as an international leader, focused on the agenda of emerging economic powers who prize stability, and in fact have much to lose from conflict and power struggles between rich countries.

Onshore wind and solar could provide 226GWh of electricity without impairing food production, says Friends of the Earth

England could produce 13 times more renewable energy than it does now, while using less than 3% of its land, analysis has found.

Onshore wind and solar projects could provide enough electricity to power all the households in England two and a half times over, the research by Exeter University, commissioned by Friends of the Earth (FoE), suggested.

G20 countries spent $142bn in three years to expand operations despite a G7 pledge to stop doing so, study finds

The world’s biggest economies have continued to finance the expansion of fossil fuels in poor countries to the tune of billions of dollars, despite their commitments on the climate.

The G20 group of developed and developing economies, and the multilateral development banks they fund, put $142bn (£112bn) into fossil fuel developments overseas from 2020 to 2022, according to estimates compiled by the campaigning groups Oil Change International (OCI) and Friends of the Earth US.

If the anomaly does not stabilise by August, ‘the world will be in uncharted territory’, says climate expert

Another month, another global heat record that has left climate scientists scratching their heads and hoping this is an El Niño-related hangover rather than a symptom of worse-than-expected planetary health.

Global surface temperatures in March were 0.1C higher than the previous record for the month, set in 2016, and 1.68C higher than the pre-industrial average, according to data released on Tuesday by the Copernicus Climate Change Service.

Leaders need to persuade others of the need for environmental measures rather than capitulate in the face of political headwinds

Last month, a survey of public opinion in Germany, France and Poland found that a majority in each country would support more ambitious policies to tackle the climate emergency. The same study also found unexpectedly widespread support for pan-European action linking green goals to other priorities such as economic security. Who knew, at a time when warnings of a popular “green backlash” are rife?

Unfortunately, Europe’s politicians are now on a very different page. Rattled by farmers’ protests – which radical-right parties have swiftly co-opted as a new front in their culture wars – Brussels and national governments have been busily sounding a disorderly, panicked retreat on environmental targets. Since the turn of the year, the U-turns and capitulations have come thick and fast.

Australian limits on acceptable levels of these toxic chemicals in drinking water ‘orders of magnitude’ higher than in US

High levels of so-called forever chemicals have been found in surface and groundwater all over the world, with Australia one of several hotspots for toxic PFAS, a University of New South Wales study has found.

Researchers examined groundwater samples from around the world and found 69% had per-and poly-fluoroalkyl substances (PFAS) at levels above Canada’s safe drinking water criteria and 32% had levels higher than the US proposed drinking water hazard index.

Around 1m people, including 13,000 youths, especially vulnerable because they can do little to protect themselves, co-author says

Nearly half of US prisons draw water from sources likely contaminated with toxic PFAS “forever chemicals”, new research finds.

At least around 1m people incarcerated in the US, including 13,000 juveniles, are estimated to be housed in the prisons, and they are especially vulnerable to the dangerous chemicals because there is little they can do to protect themselves, said Nicholas Shapiro, a study co-author at the University of California in Los Angeles.

Livestock bosses celebrate outcome at online summit, while critics condemn failure to tackle meat and dairy consumption

Lobbyists for the world’s biggest meat companies have lauded a better than expected outcome at Cop28, which they say left them “excited” and “enthusiastic” for their industry’s prospects.

US livestock bosses reflected on the conference’s implication for their sector on a virtual panel, fresh from “sharing US agriculture’s story” at the climate summit in December.

Campaigners and climate scientists had hoped the summit, which was billed as a “Food Cop” because of its focus on farming, would result in governments agreeing to ambitious action to transform food systems in line with the goals of the Paris climate agreement.

Footage captures flooding near the rural township of Charleville following a weekend of heavy rain in parts of southern Queensland and northern New South Wales. Communities across the region have been impacted by flooding, with some isolated by road closures.

According to the Bureau of Meteorology, the Warrego River gauge near Bakers Bend, in south-west Queensland, recorded a peak of 10.16m on Monday morning

Russia’s government has declared flooding in the Orenburg region a federal emergency, state media has reported.

The floods, caused by rising water levels in the Ural River, forced more than 4,000 people, including 885 children, to evacuate, the regional government said. The state news agency Tass said a further 2,000 homes were flooded, bringing the total to nearly 6,300 in the region

When I set up my honeybee hive, I had no idea I might be harming wild bee species. Now I’ve found better ways to encourage biodiversity

I took up urban beekeeping more than a decade ago with the best intentions. I wanted to help to save bees from the many threats they faced in the countryside – the modern farming practices that douse crops in toxic pesticides and rob bees of wildflower meadows. My small back garden filled with bee-friendly flowers seemed like a paradise in comparison.

But what I didn’t know was that by keeping bees I would only be helping one species of bee – the domesticated honeybee, which doesn’t really need saving – and possibly harming others.

The last time Brood XIX and Brood XII emerged from underground at the same time, Thomas Jefferson was president

They look a little like cockroaches and have bulging orange eyes, and trillions of them are about to erupt from the earth in much of the midwestern and eastern United States. The emergence of two groups of cicadas will assemble a chorus of the insects not seen in several hundred years, experts say.

The simultaneous appearance of the two cicada broods – known as Brood XIX and Brood XII – is a rare event, not having occurred since 1803, a year when Thomas Jefferson was US president. “It’s really exciting. I’ve been looking forward to this for many years,” said Catherine Dana, an entomologist who specializes in cicadas at the University of Illinois at Urbana-Champaign. “For the public, it’s going to be a really special experience.”

Global concentrations of carbon dioxide, methane and nitrous oxide climbed to unseen levels in 2023, underlining climate crisis

The levels of the three most important heat-trapping gases in the atmosphere reached new record highs again last year, US scientists have confirmed, underlining the escalating challenge posed by the climate crisis.

The global concentration of carbon dioxide, the most important and prevalent of the greenhouse gases emitted by human activity, rose to an average of 419 parts per million in the atmosphere in 2023 while methane, a powerful if shorter-lasting greenhouse gas, rose to an average of 1922 parts per billion. Levels of nitrous oxide, the third most significant human-caused warming emission, climbed slightly to 336 parts per billion.

Experts say ‘bare minimum’ building codes and a lack of interest from builders are making Australian bathrooms less energy-efficient

• Get our morning and afternoon news emails, free app or daily news podcast

A long shower at the end of the day might be a relaxing escape from reality, but there is a reason to stay alert. Energy efficiency experts say the way Australian bathrooms are being built will drain your wallet – and the environment.

Alan Pears, a senior industry fellow at RMIT who helped develop Australia’s appliance energy star ratings, describes showers as “almost perfectly designed to waste energy and make you feel uncomfortable”. He says bathrooms lack “basic design principles” and are often cold and poorly ventilated, which exacerbates hot water use.

Climate activist detained after Extinction Rebellion protesters tried to block road near Dutch parliament

Greta Thunberg was detained by police at a demonstration in The Hague, in the Netherlands.

The climate activist was put in a bus by local police along with other protesters who tried to block a major highway into the city on Saturday.

Regulator faces accusation of acting unlawfully in its investigation of Global Warming Policy Foundation

The Charity Commission is facing a legal challenge by MPs over its failure to investigate campaigning by a thinktank that questions climate science.

Liberal Democrat MP Layla Moran, Labour’s Clive Lewis and Green MP Caroline Lucas, supported by the Good Law Project, have sent a legal letter to the regulator over an unresolved complaint they made in October 2022.

Testing of 40 types of bandages found 65% had alarming levels of ‘forever chemicals’ in adhesive flaps and pads that touch wounds

Many popular US bandage brands contain alarming levels of toxic PFAS “forever chemicals”, new research suggests, raising questions about the products’ safety.

Testing of 40 types of bandages made by companies such as Band-Aid, Curad, Walmart and CVS found 26 products, or 65%, contain alarming levels of a marker of PFAS. The chemicals were detected in the adhesive flaps and in absorbent pads that press against wounds.

A supermarket is using eye-tracking technology to find what messaging encourages take-up of unpackaged fruit and veg

With thick black frames and hidden cameras, the glasses look designed for espionage or the metaverse but instead the eye-tracking headgear is being deployed to get inside shoppers’ heads as part of the drive to cut plastic packaging from the weekly food shop.

It is an unlikely scene. Hooked up with the glasses a shopper is being tailed around a Waitrose produce department by a researcher carrying a large tablet that displays live footage of them picking up banal things such as potatoes, apples and bananas.

California, Vermont and Colorado push for ban after slow federal response to research finding forever chemicals in period products

State lawmakers in California, Vermont and Colorado are working to ban the sale of period products containing highly toxic “forever chemicals”, or PFAS, nearly a year after a report revealed the chemicals were found in everything from tampon applicators to period underwear.

Despite a growing awareness of the dangers and ubiquity of PFAS, federal regulators have been slow to respond to the bombshell 2023 report from the University of Notre Dame, in which researchers found forever chemicals in various menstrual products including those mentioned above and more. Federal bills designed to address PFAS in everyday consumer items – including period products – stalled last year in large part due to chemical industry lobbyists.
