Trials will test ways to block sunlight and slow climate crisis that threatens to trigger catastrophic tipping points
Real-world geoengineering experiments spanning the globe from the Arctic to the Great Barrier Reef are being funded by the UK government. They will test sun-reflecting particles in the stratosphere, brightening reflective clouds using sprays of seawater and pumping water on to sea ice to thicken it.
Getting this “critical missing scientific data” is vital with the Earth nearing several catastrophic climate tipping points, said the Advanced Research and Invention Agency (Aria), the government agency backing the plan. If demonstrated to be safe, geoengineering could temporarily cool the planet and give more time to tackle the root cause of the climate crisis: the burning of fossil fuels.

On average, five fatal whale strikes occur in the country’s waters each year, the highest in the world – and just a fraction of the total number killed, say researchers
Photographs by Francis Pérez
The memory of a blue whale gliding past his small boat haunts Patricio Ortiz. A deep wound disfigured the cetacean’s giant body – a big chunk had been ripped from its dorsal fin. Cargo ships are the only adversary capable of inflicting such harm on a blue whale, he says.
“Nothing can be done when they’re up against those floating monsters.”

Feeding the world sustainably is an incredibly complex challenge, yet some people are trying to sell us a bucolic fairytale
The fire that has just destroyed 500 hectares (1,230 acres) of Dartmoor should have been impossible. It should not be a fire-prone landscape. But sheep, cattle and ponies have made it so. They selectively browse out tree seedlings, preventing the return of temperate rainforest, which is extremely difficult to burn. In dry weather, the moor grass, bracken and heather covering the deforested landscape are tinder.
The plume of carbon dioxide and smoke released this week is one of the many impacts of livestock grazing. But several recent films, alongside celebrities, politicians, billionaires and far-right podcasts, seek to persuade us that cattle and sheep are good for the atmosphere and the living planet. This story, wrapped in romantic cottagecore, is now the most active and seductive frontier of climate-science denial. It is heavily promoted by the meat industry, which is as ruthless and machiavellian as the fossil fuel industry. It sows confusion among people desperately seeking to do the right thing in an age of misinformation.

Paper in Nature Climate Change journal reveals major role wealthy emitters play in driving climate extremes
The world’s wealthiest 10% are responsible for two-thirds of global heating since 1990, driving droughts and heatwaves in the poorest parts of the world, according to a study.
While researchers have previously shown that higher income groups emit disproportionately large amounts of greenhouse gases, the latest survey is the first to try to pin down how that inequality translates into responsibility for climate breakdown. It offers a powerful argument for climate finance and wealth taxes by attempting to give an evidential basis for how many people in the developed world – including more than 50% of full-time employees in the UK – bear a heightened responsibility for the climate disasters affecting people who can least afford it.

Ørsted cancels fourth stage of Hornsea project off Yorkshire coast, which was set to include enough turbines to power 1m homes
The world’s biggest wind power developer has cancelled plans for one of the UK’s largest offshore windfarms in a significant blow to the government’s green energy targets.
The Danish wind power company Ørsted said the Hornsea 4 project no longer made economic sense because of soaring costs in the industry’s global supply chain, after it won a government contract two years ago.

Data suggests pollution from energy is falling again after previously stalling, but experts say faster growth needed to achieve Labor goal of 82% renewable electricity by 2030

Renewable energy generation rose substantially in Australia’s main power grid over the past year, producing 43% of electricity used across the five eastern states and the ACT between January and March.
The increase – from 39% last year – came as generation from black and brown coal-fired power plants fell to its lowest level on record for the first quarter, in part due to ageing stations being unavailable due to outages. Gas-fired electricity generation was also down.

Emissions from abandoned coalmines, oil and gas wells globally are larger than any single country except China, the US and Russia
Abandoned coalmines and oil and gas wells are now one of the biggest sources of the powerful greenhouse gas methane, new data shows, and little effort is being made to clean them up.
The methane emissions from abandoned fossil fuel infrastructure now exceed those from Iran, and if considered as a country would be the fourth biggest source in the world, behind China, the US and Russia.

Whitehall analysis provides no data or research to support the government argument that environmental legislation holds up building
There is very little evidence that protections for nature are a blocker to development, the government has admitted in its own impact assessment of the controversial new planning and infrastructure bill.
The analysis by Whitehall officials provides no data or research to back up the government’s central argument that it is environmental legislation that holds up building.

Exclusive: Attack damaged €1.5bn containment structure over nuclear reactor with repair costs likely to be borne by western governments
A Russian Shahed drone costing up to £75,000 is estimated to have inflicted tens of millions worth of damage to the site of the Chornobyl nuclear power plant, according to initial assessments and engineering experts.
The cost of a full fix is likely to be borne by western governments including the UK, because initial estimates are that a complete repair will cost more than the €25m available in a special international contingency fund.

Termites -- infamous for their ability to destroy wood -- are rarely welcomed into rainforests that have been painstakingly replanted. But a new paper suggests that termite transplants may be necessary to help regenerating forests to thrive. Scientists found that termites are not thriving in replanted rainforests in Australia. Because decomposers like termites are essential for recycling nutrients and carbon, the researchers worry that the insect's slow recovery could hinder the growth and health of the young forests.
