State, which just had its hottest year since 1895, will ban offshore wind power, boost natural gas and reduce gas pipeline rules

Climate change will be a lesser priority in Florida and largely disappear from state statutes under legislation signed on Wednesday by the state’s governor, Ron DeSantis, in a move which experts say ignores the reality of Florida’s climate threats.

The legislation, which comes after Florida had its hottest year on record since 1895, also bans power-generating wind turbines offshore or near the state’s lengthy coastline.

Sir John Armitt urges ministers to act swiftly or risk impeding growth and jeopardising climate targets

Rishi Sunak’s U-turns over net zero have delayed progress on vital infrastructure that is needed for economic growth, the government’s advisers have said.

Sir John Armitt, the chair of the National Infrastructure Commission (NIC), said good progress had been made on renewable energy in the past five years, but changes to key policies, including postponing a scheme to boost heat pump takeup, had created uncertainty and delay.

The government will fail to meet its targets on heat pump rollout.

The promised lifting of a ban on new onshore windfarms has not gone far enough.

Massive investment is needed in the electricity grid.

There is no proper plan for rail in the north and Midlands now that the northern leg of HS2 has been cancelled, severely inhibiting economic growth in those regions.

Water bills will need to go up to fix the sewage crisis, and more reservoirs are needed to avoid drought, while water companies have done too little to staunch leaks.

The UK lacks a coherent strategy on flooding, with more than 900,000 properties at risk of river or sea flooding and 910,000 at risk of surface water flooding.

Good progress has been made on the rollout of gigabit broadband around the country.

Early springs mean food for young of arrivals from west Africa has already disappeared; this year they face the opposite problem

Migratory birds, especially those long-distance travellers that winter in sub-Saharan Africa, are struggling with the effects of climate change. Specifically, the trend towards earlier springs is causing problems, because when they arrive at their usual time – between mid-April and early May – nature’s calendar has shifted forwards and spring is almost over.

This is a particular problem for three species that travel from west Africa to breed in British oakwoods: the wood warbler, the redstart and the pied flycatcher. This trio feed their young on oak moth caterpillars, but when spring comes early these have already emerged and are beginning to pupate, so the chicks starve.

‘One woman heard tree branches snapping and jumped out of bed – just in time to see her mattress float away as the back half of her house melted into the darkness’

I started my Shifting Sands series seven years ago to look at how the world is running out of usable sand. It’s the next big resource crisis. I’m from Singapore, the world’s biggest importer of sand per capita, due to the scale of its land reclamation. That was the starting point of what I had initially mapped out as a global project, investigating the extraction of and uses of sand, its consequences and alternatives.

I photographed in Singapore, China, Malaysia and Vietnam. The Mekong Delta in Vietnam is experiencing rapid erosion due to large-scale sand mining and China damming the river upstream. I went to a number of villages with researchers. We went to the commune of Hiep Phuoc, southeast of Saigon, where this picture was made, just five days after a number of villagers – including tea-seller Nguyen Thi Hong, 45, who appears in this image – had lost their homes.

Beverly Lofton’s home in south Los Angeles used to have a water-guzzling grass lawn. Today, it’s a verdant microfarm that uses solar power and recycled water to grow carrots, beets, potatoes and more, with the bounty distributed to her neighbors. The 67-year-old’s switch was a bold move in a city ruled by cars and concrete, and where the impact of extreme heat and water shortages are acutely felt. It’s also a powerful rebuttal to food insecurity and big agriculture, in a neighborhood considered a “food desert”.

Exclusive: Judge accused Robert Courts of ‘mischaracterising evidence’ against Trudi Warner

The government’s most senior law officer is to appeal against a decision not to allow a contempt of court action against climate campaigner Trudi Warner for holding a placard on the rights of jurors outside a British court, the Guardian can reveal.

Mr Justice Saini ruled at the high court last month there was no basis to take action against Warner, 69, for holding up the sign informing jurors of their right to acquit a defendant based on their conscience. He said the government’s claim that her behaviour fell into the category of criminal contempt was “fanciful”.

Missing a target doesn’t mean the sense of emergency should fade. What it must do is stop politicians dithering – and fast

I remember the first time I heard the 1.5C target. It was in a room at the Copenhagen climate talks in 2009. With the expectation of a binding agreement slipping away and negotiations failing, some of us activists joined delegates from vulnerable African and island nations in chanting “1.5 to stay alive”. It was a frank recognition that the 2C goal the climate diplomats were endlessly talking about – though not pursuing – was insufficient to deal with the increasingly clear realities of climate science.

Since then, three things have happened.

Bill McKibben is the founder of Third Act, which organizes people over 60 for action on climate and democracy

Ban Khun Samut Chin, a coastal village in Samut Prakan province, Thailand, has been slowly swallowed by the sea over the past few decades. This has led to the relocation of the school and many homes, resulting in a dwindling population. Currently, there are only four students attending the school, often leaving just one in each classroom. The village has experienced severe coastal erosion, causing 1.1-2km (0.5-1.2 miles) of shoreline to disappear since the mid-1950s

Free-roaming animals reintroduced in Romania’s Țarcu mountains are stimulating plant growth and securing carbon stored in the soil while grazing

A herd of 170 bison reintroduced to Romania’s Țarcu mountains could help store CO2 emissions equivalent to removing almost 2m cars from the road for a year, research has found, demonstrating how the animals help mitigate the worst effects of the climate crisis.

European bison disappeared from Romania more than 200 years ago, but Rewilding Europe and WWF Romania reintroduced the species to the southern Carpathian mountains in 2014. Since then, more than 100 bison have been given new homes in the Țarcu mountains, growing to more than 170 animals today, one of the largest free-roaming populations in Europe. The landscape holds the potential for 350-450 bison.

Cross-party group of 50 calls on prime minister to appoint climate envoy and back Beyond Oil and Gas Alliance

A cross-party group of MPs and peers has urged Rishi Sunak to make a U-turn on his oil and gas extraction plans as part of a broader plea to increase efforts to address the climate crisis.

The 50 politicians, including three Conservatives, wrote to the prime minister calling for the UK to regain its international leadership on the crisis by ending the licensing of new oil and gas fields, appointing a climate envoy, and backing the Beyond Oil and Gas Alliance.

The practice of recording firsthand observations about nature goes back centuries and provides an invaluable resource

Britain has a long tradition of volunteer naturalists dating back 250 years to the Rev Gilbert White in Selborne, Hampshire, best known for his classic book The Natural History of Selborne (1789).

In recent times, Rosemary Parslow has detailed the plants of the Isles of Scilly, many found nowhere else in Britain thanks to the sub-tropical climate of the islands.

Human-caused climate crisis brought soaring temperatures across Asia, from Gaza to Delhi to Manila

The record-breaking heatwave that scorched the Philippines in April would have been impossible without the climate crisis, scientists have found. Searing heat above 40C (104F) struck across Asia in April, causing deaths, water shortages, crop losses and widespread school closures.

The extreme heat was made 45 times more likely in India and five times more likely in Israel and Palestine, the study found. The scientists said the high temperatures compounded the already dire humanitarian crisis in Gaza, where displaced people are living in overcrowded shelters with little access to water.

Democrats on the House oversight committee sent letters to oil executives asking about alleged $1bn quid pro quo offer

House Democrats have launched an investigation into a meeting between oil company executives and Donald Trump at his Mar-a-Lago home and club last month, following reports that the former president offered to dismantle Biden’s environmental rules and requested $1bn in contributions to his presidential campaign.

Democrats on the House oversight committee late on Monday evening sent letters to nine oil executives requesting information on their companies’ participation in the meeting.

Experts say changing climate is ‘threat multiplier’ and that US and Germany already include it in planning

The US, Germany and other countries are putting the climate crisis at the heart of their national security plans but the UK is failing to do likewise, experts have told the government.

Extreme weather and heat are killing increasing numbers of people, damaging economies and forcing millions around the world to flee their homes, adding to an already unstable geopolitical situation, MPs were told on Tuesday at a select committee hearing.

Extra 270 million adults aged 69 or over will suffer dangerous heat levels of 37.5C amid global heating and ageing populations

The heat exposure of older people will at least double in all continents by 2050, according to a study that highlights the combined risk posed by a heating world and an ageing population.

Compared with today, there will be up to an extra 250 million people aged 69 or above who are exposed to dangerous levels of heat, defined as 37.5C. The paper warned this is likely to create biological and social vulnerability hotspots with increasing concentrations of older adults and high temperature extremes.

IPS report says replacement fuels well off track to replace kerosene within timeframe needed to avert climate disaster

Hopes that replacement fuels for airplanes will slash carbon pollution are misguided and support for these alternatives could even worsen the climate crisis, a new report has warned.

There is currently “no realistic or scalable alternative” to standard kerosene-based jet fuels, and touted “sustainable aviation fuels” are well off track to replace them in a timeframe needed to avert dangerous climate change, despite public subsidies, the report by the Institute for Policy Studies, a progressive thinktank, found.

Jannine Mancilla, 32, and Nicole Macias, 34, bonded over a shared love of DIY fashion and hand-me-downs, and frustrations with an environmentally-destructive industry and a throwaway culture that creates huge amounts of waste. So they came up with a radical idea: asking people to offer up their old clothes – for free. Their Los Angeles clothing swaps have grown from humble origins to “overwhelmingly” popular events that receive hundreds of pounds of clothing donations each month, helping attendees save the planet and keep money in their pockets.

The climate crisis can seem intractable – especially in an election year. But the remarkable actions of individuals are reason for hope

The hottest year on record. Extreme drought, wildfires and flooding. Despairing scientists, wildlife loss and rampant waste. The sheer scale of the climate crisis can feel overwhelming.

And when it comes to taking serious action, politicians move at a glacial pace, and the very real possibility of another Donald Trump presidency could stymie progress even further.

British Columbia wildfire service says blaze is burning 2km from Fort Nelson and encourages remaining people to leave

An intense wildfire could hit a town in western Canada on Monday, based on forecasts of strong winds that have been fueling the out-of-control blaze which has already forced the evacuation of thousands, fire experts and officials warned.

The British Columbia wildfire service said the blaze is burning just 2km (1.2 miles) north-west of Fort Nelson, which has already seen about 3,500 people evacuated from there after an order to leave was issued on Friday.
