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.

DoJ says Clean Air Act creates program to oversee air pollution and ‘displaces’ states’ ability to regulate it

The US justice department on Wednesday filed lawsuits against Hawaii and Michigan over their planned legal action against fossil fuel companies for harms caused by the climate crisis, claiming the state actions conflict with federal government authority and Donald Trump’s energy dominance agenda.

The suits, which legal experts say are unprecedented, mark the latest of the Trump administration’s attacks on environmental work and raise concern over states’ abilities to retain the power to take climate action without federal opposition.

Donald Trump signed 141 executive orders since returning to the presidency in January, including enacting steep tariffs, ending birthright citizenship, curbing DEI and “gender radicalism” in the military, and pardoning January 6 rioters.

The US president promised in his inaugural speech that these orders would amount to a “complete restoration of America”.

I support the Climate Paradox report from the Tony Blair Institute, but his foreword risks compromising what must be achieved

• David King was chief scientific adviser to the UK government under Tony Blair, and is founder and chair of the global Climate Crisis Advisory Group

I have always been proud of the progress the UK made between 2003 and 2007 in formulating a credible response to the climate change. Under Tony Blair’s leadership, the UK placed climate at the heart of global diplomacy. At the time, our understanding was based largely on scientific projections and models. Today, the crisis is in full view – faster and more devastating than many imagined. The world is now experiencing the daily impacts of climate breakdown, and our responses must reflect this escalating emergency. We need measured, strategic, sustained and, above all, urgent interventions to ensure a manageable future for humanity.

That is why I support much of the thrust of The Climate Paradox report from the Tony Blair Institute. It rightly recognised that the era of endless summits and slogans must give way to one of delivery and impact. But the comments I gave were prior to seeing the foreword, and while there has been some clear misinterpretation from elements of the media, I do believe it has removed the balance of the report in ways that risk undermining what still can – and must – be achieved.

Exclusive: Britain is key financial hub for destructive fossil fuel mega-projects, according to research

Banks in the City of London have poured more than $100bn (£75bn) into companies developing “carbon bombs” – huge oil, gas and coal projects that would drive the climate past internationally agreed temperature limits with catastrophic global consequences – according to a study.

Nine London-based banks, including HSBC, NatWest, Barclays and Lloyds are involved in financing companies responsible for at least 117 carbon bomb projects in 28 countries between 2016 – the year after the landmark Paris agreement was signed – and 2023, according to the study.

Donald Trump has launched an unprecedented assault upon the environment, instigating 145 actions to undo rules protecting clean air, water and a livable climate in this administration’s first 100 days – more rollbacks than were completed in Trump’s entire first term as US president.

Trump’s blitzkrieg has hit almost every major policy to shield Americans from toxic pollution, curb the worsening impacts of the climate crisis and protect landscapes, oceans, forests and imperiled wildlife.

Donald Trump has never been mistaken for an environmentalist, having long called the climate crisis a “giant hoax” and repeatedly lauding the supposed virtues of fossil fuels.

But the US president’s onslaught upon the natural world in this administration’s first 100 days has surprised even those who closely charted his first term, in which he rolled back environmental rules and tore the US from the Paris climate agreement.

A warming tundra has seen unexpected shifts, raising the alarm about fragile ecosystems and those who rely on them

Scientists studying Arctic plants say the ecosystems that host life in some of the most inhospitable reaches of the planet are changing in unexpected ways in an “early warning sign” for a region upended by climate change.

In four decades, 54 researchers tracked more than 2,000 plant communities across 45 sites from the Canadian high Arctic to Alaska and Scandinavia. They discovered dramatic shifts in temperatures and growing seasons produced no clear winners or losers. Some regions witnessed large increases in shrubs and grasses and declines in flowering plants – which struggle to grow under the shade created by taller plants.

Aluminium emissions from satellites as they fall to Earth and burn up is becoming more significant as their numbers soar

Right now there are more than 9,000 satellites circumnavigating overhead, keeping track of weather, facilitating communications, aiding navigation and monitoring the Earth. By 2040, there could be more than 60,000. A new study shows that the emissions from expired satellites, as they fall to Earth and burn up, will be significant in future years, with implications for ozone hole recovery and climate.

Satellites need to be replaced after about five years. Most old satellites are disposed of by reducing their altitude and letting them burn up as they fall, releasing pollution into Earth’s atmosphere such as aerosolised aluminium. To understand the impact of these growing emissions from expired satellites, researchers simulated the effects associated with an annual release of 10,000 tonnes of aluminium oxide by 2040 (the amount estimated to be released from disposal of 3,000 satellites a year, assuming a fleet of 60,000 satellites).

Labour politicians warn former PM had boosted Tory and Reform climate sceptics on the eve of local elections

Tony Blair has been forced by Downing Street to row back from his criticism of the government’s net zero strategy after furious Labour politicians warned he had given a boost to Tory and Reform sceptics on the eve of the local elections.

Climate experts also accused the former prime minister of granting political cover to fossil fuel interests and weakening momentum behind the UK’s legally binding target to reach net zero emissions by 2050.

Sir Tony Blair’s ill-conceived contribution to the climate debate was a political gift to Nigel Farage. But public support for the green transition remains strong

The Climate Change Committee’s latest report on the UK’s response to unprecedented environmental challenges makes for grim reading. Recalling the extreme weather swings of the last few years – which delivered both the wettest 18 months on record and the largest number of wildfires – the report’s authors deplore the current inadequacy of provision to protect the nation against risks which are now a lethal reality. The threat represented by flooding, said the chair of the committee’s adaptation group, Lady Brown, “is not tomorrow’s problem. It’s today’s problem. And if we don’t do something about it, it will become tomorrow’s disaster.”

An assessment so scathing, from such a source, deserved to be at the centre of political discussion ahead of Thursday’s local elections. Instead, Wednesday’s front pages were dominated by a considerably less useful contribution to the climate debate. In a foreword to a report from his eponymous Tony Blair Institute (TBI), Sir Tony Blair suggested that governments should dial down efforts to limit the use of fossil fuels in the short term, or risk alienating voters allegedly put off by the “irrationality” and cost of green policies. Politicians’ focus, he insisted, should shift to investing speculatively in technologies for the future such as carbon capture and storage.

Exclusive: Stuart Bonds could hand the Nationals the seat of Hunter thanks to a preference deal and ‘last minute’ change to how-to-vote cards

A One Nation candidate who could hand the Nationals the seat of Hunter, thanks to a handshake preference deal, has called public health officials “little Hitlers” and promoted a conspiracy theory alleging the government has used the climate crisis to control every aspect of people’s lives.

Stuart Bonds told a livestreamed forum with rightwing activists last week that the federal government should not do anything to address climate change. He also claimed “a crime” was committed against Australians during the Covid pandemic, alleging they were used “as an experiment to sell pharmaceutical projects”.

The former PM has form when it comes to pushing corporate interests and meeting populists halfway

When Tony Blair came out this week to say current net zero policies were “doomed to fail”, there was something familiar in his arguments: phasing out fossil fuels wouldn’t work because people perceived it as expensive, arduous and not their problem. Stop banging on about renewables; won’t someone think of the things we don’t know how to do, like carbon capture and such wizardry as is still locked in tech bros’ imaginations? Basically, net zero had lost the room, according to the former prime minister. And if anyone knows where the room is, and how to get it back, it must be him.

The Tony Blair Institute (TBI) issued a statement on Wednesday saying that, in fact, it believes the government’s net zero policy is “the right one”. But this is a familiar trajectory for the former prime minister. He said something similar about “woke”, which sadly lost the room in 2022. “Plant Labour’s feet clearly near the centre of gravity of the British people,” Blair advised Starmer. “[They] want fair treatment for all and an end to prejudice, but distrust and dislike the ‘cancel culture’, ‘woke’ mentality.” What exactly does “woke” mean, if not an end to prejudice? Just how effective is cancel culture if Blair himself could work as a lobbyist for a Saudi oil firm in 2016, advise the government of Kazakhstan after it brutally suppressed public protests in 2011, and yet still walk among us as the voice of the progressive left? Memo to my fellow cancellers: we are bad at this.

Former Labour PM accused of ‘handing talking points’ to Tories and Reform after saying net zero strategy faltering

• UK politics live – latest updates

Climate experts and politicians have criticised Tony Blair for claiming that any strategy that relied on rapidly phasing out fossil fuels was “doomed to fail”.

The former prime minister’s comments, published in a report from the Tony Blair Institute for Global Change (TBI), prompted an internal row in Labour, with some accusing him of playing into the hands of a narrative used by rightwing parties to delay climate action.

Temperatures south Asians dread each year arrive early as experts talk of ever shorter transition to summer-like heat

The summer conditions south Asian countries dread each year have arrived alarmingly early, and it’s only April. Much of India and Pakistan is already sweltering in heatwave conditions, in what scientists say is fast becoming the “new normal”.

Temperatures in the region typically climb through May, peaking in June before the monsoon brings relief. But this year, the heat has come early. “As far as Asia and the Indian subcontinent are concerned, there was a quick transition from a short window of spring conditions to summer-like heat,” said GP Sharma, the meteorology president of Skymet, India’s leading private forecaster.

Plans to protect UK from extreme weather are inadequate, Climate Change Committee says in scathing assessment

Labour is putting people, the economy and the environment in increasing peril by failing to act on the effects of the climate crisis, the UK’s climate watchdog has said.

Flooding, droughts and heatwaves are all increasing in severity due to climate breakdown, but current plans to protect people, land and infrastructure against extreme weather have been judged inadequate in a scathing assessment of the UK’s preparedness.
