Representatives of Heartland Institute linking up with MEPs to campaign against environmental policies

Climate science deniers from a US-based thinktank have been working with rightwing politicians in Europe to campaign against environmental policies, the Guardian can reveal.

MEPs have been accused of “rolling out the red carpet for climate deniers” to give them a platform in the European parliament, amid warnings of a “revival of grotesque climate denialism”.

Climate crisis is making it harder for insurance companies to operate, with many pausing or withdrawing policies

Homeowners in the United States are facing an enormous financial crunch due to the climate crisis, with many struggling to find insurance or even dropping premiums that are soaring due to a mounting toll of wildfires, hurricanes and other disasters, new federal government data shows.

The figures, the most comprehensive numbers ever released by the US treasury department on the issue, show insurance premiums are increasing quickly across the country, with people living amid the greatest climate-driven risks experiencing the steepest rises of all. In the four years to 2022, people living in the top 20% riskiest places for such perils paid, on average, 82% more than those in the 20% lowest climate risk zip codes.

António Guterres issues warning at Davos, days after Donald Trump pulled US out of Paris climate agreement

• Davos day two live – latest updates

The world’s addiction to fossil fuels is a “Frankenstein’s monster sparing nothing and no one”, the UN secretary general, António Guterres, told leaders at the World Economic Forum in Davos on Wednesday.

“Our fossil fuel addiction is a Frankenstein’s monster, sparing nothing and no one. All around us, we see clear signs that the monster has become master,” Guterres said in a speech days after 2024 was revealed to have been the hottest year on record and Donald Trump began his second term as US president by pulling the country out of the Paris climate agreement and pledging to “drill, baby, drill” for more oil and gas. The fossil fuel industry gave $75m (£60m) to Trump’s campaign.

Gusts could peak at 70mph (113km/h) along the coast and 100mph (160km/h) in the mountains and foothills

Winds picked up on Tuesday in southern California and at least a couple of new wildfires broke out as firefighters remained on alert in extreme fire weather, two weeks after major blazes started, two of them still burning, in the Los Angeles area.

The fresh high winds – that are coming amid still bone-dry conditions – mark the end of a break in dangerous high fire-risk conditions that have allowed the beleaguered city’s firefighters to largely contain the disastrous blazes that have burnt thousands of homes. The fires have killed at least 27 people and destroyed more than 14,000 structures since they broke out during fierce winds on 7 January.

More than 40% of individual corals monitored around a Great Barrier Reef island were killed last year in the most widespread coral bleaching outbreak to hit the reef system, a study has found.

Scientists tracked 462 colonies of corals at One Tree Island in the southern part of the Great Barrier Reef after heat stress began to turn the corals white in early 2024. Researchers said they encountered “catastrophic” scenes at the reef.

Critical CO2 stores held in permafrost are being released as the landscape changes with global heating, report shows

A third of the Arctic’s tundra, forests and wetlands have become a source of carbon emissions, a new study has found, as global heating ends thousands of years of carbon storage in parts of the frozen north.

For millennia, Arctic land ecosystems have acted as a deep-freeze for the planet’s carbon, holding vast amounts of potential emissions in the permafrost. But ecosystems in the region are increasingly becoming a contributor to global heating as they release more CO2 into the atmosphere with rising temperatures, a new study published in Nature Climate Change concluded.

Artisanal shellfish farmers face ruinous losses but money meant to help is going to the powerful fishing industry, say critics

Early on a warm September morning in southern Italy, Giovanni Nicandro sets out from the port of Taranto in his small boat. Summoning his courage, the mussel farmer inspects his year’s work – only to find them all dead, a sight that almost brings him to tears.

“We have many problems,” he says. “The problems start as soon as we open our eyes in the morning.” The loss is total – not only for Nicandro but also for Taranto’s 400 other mussel farmers, after a combination of pollution and rising sea temperatures devastated their harvest.

President pledges immigration crackdown, rolls back climate rules and pardons 1,500 January 6 rioters

• Donald Trump returns to office – live updates

Donald Trump launched his second term as US president with a barrage of executive orders reaching into broad swathes of American life, from pardoning hundreds of supporters who attacked Congress on January 6, including rightwing extremists convicted of seditious conspiracy, to rolling back LGBTQ+ rights and environmental rules while declaring an immigration emergency on the southern border.

Trump and his allies had long promised a “shock and awe” approach. They did not hold back.

Donald Trump took aim at federal support for the sale of electric vehicles (EVs) on Monday, amid a flurry of promised executive orders on his first day back in the White House.

“The United States will not sabotage our own industries while China pollutes with impunity,” Trump said during a ceremony at Capitol One Arena, where he signed a raft of executive orders before a roaring crowd.

• Donald Trump inauguration – live updates

Donald Trump’s new administration confirmed on Monday on his first day in office that he will repeat his first-term move and pull the world’s second biggest emitter of planet-heating pollution out of the 2015 Paris agreement, the global treaty seeking to avoid the worst impacts of the climate crisis.

The confirmation was in a White House document entitled President Trump’s America First Priorities, in a package of measures under the headline “Make America affordable and energy dominant again”.

The billionaire’s return to power signals a new era of upheaval in US politics, marked by authoritarian ambitions, glaring conflicts and polarisation

On the surface, Donald Trump’s inauguration looked like the usual transfer of power, with political rivals exchanging polite applause. This was a facade. Mr Trump’s address feigned conciliation but was, in reality, a rightwing call to arms against his enemies, rejecting the unity the ceremony represents. Mr Trump presented a grim picture of a country on its knees that only he can revitalise. He declared not one but two national emergencies, pledging to return “millions of criminal aliens” and “drill, baby, drill” for the “liquid gold under our feet”. His alarming call to “take back” the Panama Canal from China hints at ambitions to reshape the global order, potentially through force.

A flurry of Trumpian executive orders will accelerate the climate emergency, defy the US constitution over birthright citizenship and reduce the scope of legal protections. Forget the stirring rhetoric of Kennedy; Trump’s message was blunt: enemies at home and abroad, beware. Where Roosevelt once inspired hope, Mr Trump offered fear.

Altadena’s Village Playgarden education center served diverse families with outdoor classrooms, small farm and animals – till it was destroyed by flames

In Altadena, it had become the hot ticket among the preschool set.

But when Geoff and Kikanza Ramsey-Ray first bought the two-acre property at the edge of town in 2008, it was a shambles. The home was a rental for over 30 years and the grounds were woefully neglected. Yet the couple saw promise. Nestled against Angeles Crest national forest, with a mountain view and on a road with few other homes, the place felt protected and perfect for their vision: an early education center called Village Playgarden.

Some say Trump part two needs a new strategy as ‘the novelty of mass mobilization has kind of worn off’

Prominent leftwing activists across the US say a second Trump administration demands new tactics to achieve their goals, amid expectations the huge protests that marked both the Biden and first Trump presidencies won’t materialize in the same way.

As many as 4.6 million people attended Women’s Day marches in the US the day after Donald Trump’s first inauguration. The Saturday before Trump was inaugurated for a second time, thousands turned out in Washington DC and in cities around the country as part of the People’s March, this year’s version of the Women’s March – though the turnout was much smaller than in 2017.

Unlike tariffs, a new form of protectionism could target climate-wrecking, untaxed corporations and their billionaire owners

• Gabriel Zucman is a French economist

How should Europe respond before Donald Trump’s policies destabilise the global economy? All countries will soon have to take a stand on the new US president’s tariff threats. While a shift away from free trade clearly carries risks, it also presents a valuable opportunity to reimagine our outdated international economic relations – if we can grasp what makes this moment unique.

In many ways, Trump’s economic agenda follows the Republican party playbook that dates back to Barry Goldwater’s 1964 presidential run, which launched the party’s enduring mission to dismantle Roosevelt’s New Deal. Trump claims the US was never better off than under William McKinley’s presidency (1897-1901), when the federal government, before income tax existed, was pared down to a minimum.

The global south needs a fairer deal than this one, in which it funds the lifestyle and wealth of the global north

The World Bank calculated last month that the rich world earned more than $1.4tn (£1.15tn) in loan repayments from the developing world in 2023, with the sums likely to top $2tn a year by 2030. Rich countries have in effect become the world’s bankers, squeezing debtors in the global south. Poorer nations are forced to borrow in rich-world currencies to pay for their energy and food, while their exports consist mainly of low-value goods compared with their imports.

Colonial patterns of extraction plainly did not disappear with the withdrawal of troops, flags and bureaucrats. Whether a debt crisis in the developing world occurs depends on decisions beyond its control. The risk increases if US interest rates rise and if poor nations’ exports – often priced by commodity speculators or wealthy-world buyers – fail to generate enough dollar reserves to stabilise their exchange rates.

It’s not unusual to see individuals championed as heroes of climate action, with their efforts to install rooftop solar and buy electric cars promoted as pivotal in the fight to save the planet.

Hero figures can motivate others to follow suit, but a University of Sydney study suggests the way the energy sector shapes this narrative sets individuals up to fail.

Environmentalists are braced for new construction on the president’s signature border wall – and the damage that would wreak

During Donald Trump’s first presidential term, he began an ambitious and costly border militarization program, including the construction of over 450 miles of wall that severed wildlife corridors and fragmented ecosystems in some of the country’s most remote and biodiverse regions. With his second inauguration on Monday, environmentalists are bracing for any new phase of construction that could exacerbate the ecological toll of the border wall.

“It’s an absolute travesty and a disaster for border wildlife,” said Margaret Wilder, a human-environment geographer and political ecologist at the University of Arizona, regarding the environmental impact of the existing border wall and the prospect of renewed construction. She said the wall harmed efforts “after many decades of binational cooperation between the US and Mexico to protect this fragile and biodiverse region. I don’t think Americans realize what is at stake.”

Hunger and hope in Gaza, fires in California and the Australian Open in Melbourne: the past seven days as captured by the world’s leading photojournalists

As fires set LA ablaze, some houses are left standing amid ashes thanks to concrete walls, class A wood – and luck

When last week’s fires in Los Angeles set parts of the city ablaze, one viral image was of a lone house in Pacific Palisades that was left standing while all of the homes around it were destroyed.

Architect Greg Chasen said luck was the main factor in the home’s survival, but the brand-new build had some design features that also helped: a vegetation-free zone around the yard fenced off by a solid concrete perimeter wall, a metal roof with a fire-resistant underlayment, class A wood and a front-gabled design without multiple roof lines.
