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.

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.

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.

Professionals call for a fundamental transition including controlling flight numbers

The aviation industry is “failing dramatically” in its efforts to tackle its role in the climate crisis, according to a newly formed group of aviation professionals.

They say they are torn between their passion for flying and their concern for the planet and are calling for a fundamental transition of the industry, including controlling flight numbers.

Governor is expected to sign the ‘green fee’, which adds 0.75% levy to state’s existing tax on short-term lodging

Lawmakers in Hawaii have passed first-of-its-kind legislation that will increase the state’s lodging tax to raise money for environmental protection and strengthening defenses against natural disasters fueled by the climate crisis.

Hawaii’s governor, Josh Green, supports the creation of the so-called “green fee”, and is expected to sign it.

Analysis of the election result has barely begun, but this much is clear: the country has backed a rapid acceleration towards renewable energy. Labor didn’t say much about the climate crisis during the campaign, announcing only one new policy. But Anthony Albanese and his climate change and energy minister, Chris Bowen, emerged with their ambitious goal of the country getting 82% of electricity from solar, wind and hydro by 2030 not just intact, but emphatically endorsed.

Labor’s position has been relentlessly attacked by the Coalition, rightwing organisations backed by fossil fuel interests and one of the country’s biggest news media companies. Australians rejected this comprehensively.

Doug Paulley and Kevin Jordan say their lives being ruined, and lack of effective strategy infringes their human rights

Two men who say they are being failed by the UK’s flawed response to climate breakdown are taking their case to Europe’s top human rights court.

Doug Paulley and Kevin Jordan say their lives have been ruined by the rising temperatures and extreme weather caused by the climate crisis, and that the government’s response fails to respect their human rights.

Even before his call for a net zero ‘reset’, there had been criticism of ex-PM’s lucrative links with fossil fuel nations

From the lush gardens of the Four Seasons luxury hotel in Sharm el-Sheikh, amid banks of bougainvillaea and trailing jasmine, green lawns and air-conditioned courtyards, the surrounding desert is kept at bay by hidden sprinklers, and the chaotic poverty of the rest of Egypt by high walls and discreet security.

In late 2022, on the sidelines of the Cop27 UN climate conference, the former UK prime minister Tony Blair was holding high-level meetings with senior figures from politics and business. His role in the negotiations raised questions for some, who began to worry that, having been a respected elder statesman on the subject – one who as prime minister crafted the UK’s first real climate measures, and made it the priority for the UK presidency of the G8 group of countries in 2005 – he might now be becoming, in the words of one Whitehall insider, “a serious threat to sensible climate policy”.

Layoffs and funding cuts to Fema and Noaa will impact how they predict and respond to disasters, warns professor Samantha Montano

The Trump administration’s sweeping cuts to disaster management will cost lives in the US, with hollowed-out agencies unable to accurately predict, prepare for or respond to extreme weather events, earthquakes and pandemics, a leading expert has warned.

Samantha Montano, professor of emergency management at Massachusetts Maritime Academy and author of Disasterology: Dispatches from the Frontlines of the Climate Crisis, said the death toll from disasters including hurricanes, tornadoes and water pollution will rise in the US unless Trump backtracks on mass layoffs and funding cuts to key agencies. That includes the Federal Emergency Management Agency (Fema), whose work relies heavily on the National Oceanic and Atmospheric Administration (Noaa), which is also being dismantled.

Shorter winters and thinning ice are imperiling cultural activities in the north, including hockey, broomball and hunting

Janelle Oombash stands on the smooth ice of an outdoor rink, keeping score and watching the time as two teams of teenagers run across the ice, whacking a ball with sticks under the afternoon sun. Outside the rink, a bonfire crackles, keeping spectators warm as they watch the game.

Broomball has been played for more than a century in northern Ontario. The game is similar to hockey, but players use a ball instead of a puck and wear specialized shoes rather than skates. Now 31, Oombash started playing the game at age 11. Her dad is a coach and taught her to play. “It’s a big sport. Everybody plays broomball or hockey,” she said.

Gen Z want the government to address the big structural problems: housing supply, inequality and climate

• Live results: federal election votes tracker, electorates map and seat counts

I often write about how younger Australians are carving out a different political identity from older generations. But the election result has reminded us of what cuts across age and sits in our national core. That deep-seated Aussie reaction: “yeah-nah, that’s a bit much” when things go too far. We’re allergic to imported bravado, anything too loud, too messianic. And, when pushed, we don’t shout – we shrug.

This election was one long shrug. A rejection of chaos and division, not through fury but through an assertive, ballot-powered recoil.

Five of Australia’s biggest fossil fuel producers could be on the hook for hundreds of billions of dollars in damages after a US research team developed a method to link individual companies to specific climate harms and put a dollar figure to the impact.

This is the result of a new peer-review study published in the journal Nature that sought to establish a method that would allow courts to quantify the economic loss caused by fossil fuel producers for one kind of climate impact – extreme heat.

Two groups join forces for peer-reviewed research after key contributors on Congress-mandated report dismissed

Two major US scientific societies have announced they will join forces to produce peer-reviewed research on the climate crisis’s impact days after Donald Trump’s administration dismissed contributors to a key Congress-mandated report on climate crisis preparedness.

On Friday, the American Meteorological Society (AMS) and the American Geophysical Union (AGU) said that they will work together to produce over 29 peer-reviewed journals that will cover all aspects of climate change including observations, projections, impacts, risks and solutions.

Territory’s voluntary move comes as Trump administration makes good on pledge to end lawsuits against oil and gas

Puerto Rico has voluntarily dismissed its 2024 climate lawsuit against big oil, a Friday legal filing shows, just two days after the US justice department sued two states over planned litigation against oil companies for their role in the climate crisis.

Puerto Rico’s lawsuit, filed in July, alleged that the oil and gas giants had misled the public about the climate dangers associated with their products. It came as part of a wave of litigation filed by dozens of US states, cities and municipalities in recent years.

Patience Nabukalu, who has experienced climate-related flooding, joins protestors from around the world to deliver a letter to CEO Georges Elhedery criticising the financing of oil, gas and coal projects

At nine years old, Patience Nabukalu was devastated when her friend, Kevin, died in severe flooding that hit their Kampala suburb, Nateete, a former wetland. Witnessing deaths and the destruction of homes and livelihoods in floods made worse by extreme rainfall has had a profound impact on her.

She decided to try to bring about change – to do what she could to amplify the voices of those in the Ugandan communities worst affected by the climate crisis.

Tariff chaos hampers Trump’s pledge to ‘drill, baby, drill’, but analysis still shows surge in planet-heating emissions

• ‘A ruthless agenda’: charting 100 days of Trump’s onslaught on the environment

Donald Trump’s ambitions for the US to “drill, baby, drill” for more fossil fuels have ironically been hampered by the economic chaos unleashed by his own tariffs, but the US is still on track to increase oil and gas extraction, causing a surge in planet-heating emissions, a new analysis shows.

The US was already the world’s leading oil and gas power, producing more of the fossil fuels than any country in history during Joe Biden’s administration. But Trump has sought to escalate this further, declaring an “energy emergency” to open up more land and ocean for drilling and launching an unprecedented assault on environmental regulations in his first 100 days back in the White House.

Met Service issues red warning amid deepening low pressure, while Europe experiences above average temperatures

Strong winds and flooding spread across New Zealand last week, with a state of emergency declared in Christchurch, after the country was battered by a destructive area of low pressure. A red warning, the highest warning level, was issued by the MetService (the national meteorological service).

The area of low pressure quickly deepened in the Tasman Sea off the west coast of New Zealand and travelled eastwards, with the centre of low pressure moving across the northern island and creating very strong winds, particularly through the Cook Strait, the body of water that separates the two islands. The wind direction was a south-easterly to southerly, which caused the winds to strengthen as they were funnelled between the islands.

Warm weather means strawberries, aubergines and tomatoes have come weeks earlier than expected

A glut of early strawberries, aubergines and tomatoes has hit Britain with the dry, warm weather eliminating the usual “hungry gap”, growers say.

It has been a sunny, very dry spring, with the warmest start to May on record and temperatures predicted to reach up to 30C at the earliest point on record, forecasters have said.

If further confirmation was needed that the Peter Dutton-led Coalition would take Australia aggressively backwards on dealing with the climate crisis, his final election costings released on Thursday tell the story in black and white.

The Liberal and National parties plan to gut programs designed to cut emissions and help create green industries to give the country an industrial future as demand for fossil fuels falls. They also plan to ignore advice that Australian nature is in poor and deteriorating health and strip back already limited funding for environment programs.
