Poorer countries want rapid emission cuts and more financial help in face of US leader’s stance on global heating

Developing countries are calling on the rich world to defy the US president, Donald Trump, and bridge the global chasm over climate action, before the goal of limiting global temperatures to safe levels is irretrievably lost.

Diplomats from the developing world are rallying to support Brazil, which will host a crucial climate summit in November, after last year’s talks in Azerbaijan ended in disappointment and acrimony.

Bank moves climate targets from 2030 to 2050 and waters down environmental goals in plan for Georges Elhedery

HSBC is delaying key parts of its climate goals by 20 years, while watering down environmental targets in a new long-term bonus plan for its chief executive, Georges Elhedery, that could be worth up to 600% of his salary.

The London-headquartered lender said it had launched a formal review of its net zero emissions policies and targets – which are split between its own operations and those of the clients it finances – after realising its clients and suppliers had “seen more challenges” in cutting their carbon footprint than expected.

Study found electric vehicles and batteries added largest amount to country’s clean-energy economy

Clean energy contributed a record 10% of China’s gross domestic product in 2024, an analysis has found.

With sales and investments worth 13.6tn yuan (£1.5tn; $1.9tn), the sector has now overtaken real estate sales in value.

Denise Cheung resigns after Trump appointees demand she open grand jury investigation into EPA grants

A top federal prosecutor has quit after refusing to launch what she called a politically driven investigation into Biden-era climate spending, exposing deepening rifts in the US’s premier law enforcement agency.

Denise Cheung, head of criminal prosecutions in Washington, resigned on Tuesday after Trump appointees demanded she open a grand jury investigation into Environmental Protection Agency (EPA) grants based largely on an undercover video, multiple people familiar with the matter told CNN.

Ambitious UK project aims to forecast climate catastrophes using fleets of drones, cosmic ray detection, patterns of plankton blooms and more

An ambitious attempt to develop an early warning system for climate tipping points will combine fleets of drones, cosmic ray detection and the patterns of plankton blooms with artificial intelligence and the most detailed computer models to date.

The UK’s Advanced Research and Invention Agency (Aria), which backs high-risk, high-reward projects, has awarded £81m to 27 teams. The quest is to find signals that forewarn of the greatest climate catastrophes the climate crisis could trigger. Tipping points occur when global temperature is pushed beyond a threshold, leading to unstoppable changes in the climate system.

‘Make polluters pay’ laws, led by blue states AGs, and accountability suits will be a major front for climate litigation for the coming years

Donald Trump’s re-election has “turbocharged” climate accountability efforts including laws which aim to force greenhouse gas emitters to pay damages for fueling dangerous global warming, say activists.

These “make polluters pay” laws, led by blue states’ attorneys general, and climate accountability lawsuits will be a major front for climate litigation in the coming months and years. They are being challenged by red states and the fossil fuel industry, which are also fighting against accountability-focused climate lawsuits waged by governments and youth environmentalists.

It could be wildfires, a pandemic or a financial crisis. The super-rich will flee to their bunkers – the rest of us will have to fend for ourselves

Though we might find it hard to imagine, we cannot now rule it out: the possibility of systemic collapse in the United States. The degradation of federal government by Donald Trump and Elon Musk could trigger a series of converging and compounding crises, leading to social, financial and industrial failure.

There are several possible mechanisms. Let’s start with an obvious one: their assault on financial regulation. Trump’s appointee to the US Consumer Financial Protection Bureau (CFPB), Russell Vought, has suspended all the agency’s activity, slashed its budget and could be pursuing Musk’s ambition to “delete” the bureau. The CFPB was established by Congress after the 2008 financial crisis, to protect people from the predatory activity that helped trigger the crash. The signal to the financial sector could not be clearer: “Fill your boots, boys.” A financial crisis in the US would immediately become a global crisis.

Lobbyists argued it was unfair for their industry to be treated the same as others as end product – oil and gas – inevitably produced emissions

Experts have accused the fossil fuel industry of seeking special treatment after lobbyists argued greenhouse gas emissions from oilfields should be treated differently to those from other industries.

The government is embroiled in a row over whether to allow a massive new oilfield, Rosebank, to go ahead, with some cabinet members arguing it could boost growth and others concerned it could make the goal of reaching net zero emissions by 2050 impossible to reach. Labour made a manifesto commitment to halt new North Sea licensing, but Rosebank and some other projects had already been licensed and were awaiting final approval when the party won the general election.

Divers have documented evidence of what conservationists say is widespread coral bleaching at the Ningaloo Reef off Western Australia’s north-west coast. Waters off WA have been affected by a prolonged marine heatwave since September, with ocean temperatures 1.5C higher than average over a five-month period

• Large areas of WA’s Ningaloo corals could die in ‘weeks ahead’ after widespread bleaching documented

Conservationists call for urgent government action as prolonged heatwave affects renowned reef, including Turquoise Bay, Tantabiddi and Bundegi

Divers have documented evidence of what conservationists say is widespread coral bleaching at the Ningaloo Reef off Western Australia’s north-west coast.

Photographs show bleaching at several sites along the 260km-long reef, including Turquoise Bay, Coral Bay, Tantabiddi and Bundegi (Exmouth Gulf).

The US energy secretary, Chris Wright, has said he “would love to see Australia get in the game of supplying uranium and maybe going down the nuclear road themselves”.

Australia is already the world’s fourth-largest producer of uranium, but nuclear power remains banned at national level.

A climate protester was unarmed and posed no threat when he was hit with “excruciatingly painful” pepper spray by a Victorian police officer who later remarked “they needed that”, a court has heard.

But a lawyer representing the state – in the first class action against Victoria police in relation to alleged excessive use of oleoresin capsicum (OC) spray – said the protester was part of a group that “piled” into an area and blocked their attempts to make arrests.

Those supporting the deal hope it will raise billions to help poor countries deal with climate breakdown

Brazil has asked the UN to throw out plans for a new levy on global shipping that would raise funds to fight the climate crisis, despite playing host to the next UN climate summit.

The proposed levy on carbon dioxide emissions from shipping will be discussed at a crunch meeting of the International Maritime Organisation (IMO) that begins on Monday. Those supporting the deal, including the UK, the EU and Japan, are hoping the levy will raise billions of dollars a year, which could be used to help poor countries cope with the effects of climate breakdown.

Mountain communities in southern Appalachia begin rebuilding after climate crisis-fueled disaster

It’s hard to picture what Barnardsville looked like before Hurricane Helene converted the calm creek that meanders through this North Carolina mountain into a roaring river that engulfed the community.

More than 50 homes including an entire trailer park were destroyed when Ivy Creek flooded in late September after three days of unprecedented rainfall and hurricane-force winds uprooted thousands of trees – and this close-knit community’s sense of safety.

Harmful algae bloom off south-west coast blamed for deaths of marine life and poses threat to beaches

Environmentalists in Florida are calling on the governor, Ron DeSantis, to declare an emergency as a worsening “red tide” algae bloom off the state’s south-west coast threatens popular tourist beaches and is being blamed for the deaths of wildlife including fish and dolphins.

Several counties have issued health alerts in response to the outbreak, which scientists say began in the Gulf of Mexico last year when Hurricanes Helene and Milton tore up nutrient-rich waters that feed the algae.

And the problem isn’t limited to the region – across the US, nearly a third of new homes are at high risk

The Los Angeles wildfires last month destroyed thousands of homes, killed dozens of people and left a city reeling. They also raised serious questions about the region’s future – and where Americans choose to build.

A rapidly increasing share of US homes are built in areas that are at risk of fire. In 1990, about 13% of new homes were built in places at high risk of fire. By 2020, that number had more than doubled to 31%. The numbers come from ClimateCheck, a for-profit research company that compiles risk by studying trends including rainfall, wind and temperature. But the climate crisis is just one of the reasons that more homes are unsafe.

As wildfires, floods, droughts and record-breaking temperatures have shown, the post-climate change era has arrived. Now we need honesty and action from our leaders

Not yet a quarter of the way into this century and global average temperatures are already 1.75C above the preindustrial average. January 2025 was the hottest on record and has also set a record for the highest yearly minimum global surface temperature, and likely the highest minimum in the past 120,000 years. It is part of a clear pattern. Last year’s global average was 1.6C above the preindustrial – a sobering reality check, given that, only three months ago at the UN Cop29 summit in Baku, Azerbaijan, leaders were still declaring that limiting global temperature rises to 1.5C was within reach.

We are firmly in the post-climate change world now, and the serious implications of this demand honest acknowledgment. The reality is that we are living now in a time of continual disasters that are unfolding alongside our slower, planetary scale disaster. In this riskier time, we need to prepare.

Trend towards more extreme-weather events will continue to hit crop yields and create price spikes, Inverto says

Extreme weather events are expected to lead to volatile food prices throughout 2025, supply chain analysts have said, after cocoa and coffee prices more than doubled over the past year.

In an apparent confirmation of warnings that climate breakdown could lead to food shortages, research by the consultancy Inverto found steep rises in the prices of a number of food commodities in the year to January that correlated with unexpected weather.

Residents in Sierra Madre begin cleanup effort after strongest storm of year sweeps through southern California

Residents of a southern California mountain community near the Eaton fire burn scar dug out of roads submerged in sludge on Friday after the strongest storm of the year swept through the area, unleashing debris flows and muddy messes in several neighborhoods recently torched by wildfires.

Water, debris and boulders rushed down the mountain in the city of Sierra Madre on Thursday night, trapping at least one car in the mud and damaging several home garages with mud and debris. Bulldozers on Friday were cleaning up the mud-covered streets in the city of 10,000 people.
