A ‘covalent organic framework’ can be used to capture carbon to store it or convert it for industrial use

An innocuous yellow powder, created in a lab, could be a new way to combat the climate crisis by absorbing carbon from the air.

Just half a pound of the stuff may remove as much carbon dioxide as a tree can, according to early tests. Once the carbon is absorbed by the powder, it can be released into safe storage or be used in industrial processes, like carbonizing drinks.

Satellite data analysis suggests algal blooms could be behind mass die-off in Botswana that sparked flurry of theories in 2020

More than 350 elephants that died in mysterious circumstances probably drank toxic water, according to a new paper that warns of an “alarming trend” in climate-induced poisoning.

The deaths in Botswana’s Okavango delta were described by scientists as a “conservation disaster”. Elephants of all ages were seen walking in circles before collapsing and dying. Carcasses were first spotted in north-eastern Botswana in May and June 2020, with many theories circulating about the cause of death, including cyanide poisoning or an unknown disease.

Early deaths from air pollution in US could be reduced by between 4,000 and 15,000 a year by 2035, study shows

The burning of fossil fuels that harms our climate also produces air pollution that damages ecosystems and harms our health. But we fail to tally up the benefits of reduced air pollution in our climate policies, and overlook opportunities to tackle these problems together.

A reminder of this failure is illustrated in a new study which has found that reduced air pollution from net zero policies in the US could result in a health gain of between $65bn (£51bn) and $128bn in 2035 alone.

Government approves up to four days of paid leave so workers can avoid travelling during weather emergencies

Spain’s leftwing government has approved “paid climate leave” of up to four days to allow workers to avoid travelling during weather emergencies, a month after floods killed at least 224 people.

Several companies came under fire after the 29 October catastrophe for ordering employees to keep working despite a red alert issued by the national weather agency. The firms said the authorities failed to inform them sufficiently and sent telephone alerts too late during the European country’s deadliest floods in decades.

The shortcomings of Cop29 increase the urgency for the ICJ to issue an advisory opinion on the legal obligations of states in respect to climate harm

The UN climate conference in Baku has ended with an agreement for $300bn annually, by 2035, to be provided in global finance to help less wealthy countries develop clean economies and adapt to damage from climate change. Estimates by independent economists have said the need will approach $1.3tn annually by 2030. The $1.3tn was acknowledged in the deal in Baku, but there were no firm commitments to reach that figure. The difference of $1tr each year sounds absurd, but is true.

This is why we brought a climate change case to the international court of justice (ICJ), to seek an advisory opinion on climate obligations. Hearings on the case begin next week in The Hague and the shortcomings of the Cop29 agreement make this unprecedented action – to clarify the legal obligations of states under international law in respect of climate change and the legal consequences for breaches – even more urgent.

Scientists warn Fifa’s ‘wet bulb’ temperature policy underestimates strain players undergo during matches

Footballers face a “very high risk of experiencing extreme heat stress” at 10 of the 16 stadiums that will host the next World Cup, researchers have warned, as they urge sports authorities to rethink the timing of sports events.

Hot weather and heavy exercise could force footballers to endure temperatures that feel higher than 49.5C (121.1F) in three North American countries in 2026, ­according to the study. It found they are most at risk of “unacceptable ­thermal stress” in the stadiums in Arlington and Houston, in the US, and in Monterrey, in Mexico.

Temperatures of this week would be exceptional for summer, says climatologist, never mind late November

Towns in south-west France roasted in “completely extreme” heat in the early hours of Tuesday, with overnight temperatures hitting 26.9C (80.42F).

“It’s very exceptional temperatures – even for the summer, let alone late November,” said Matthieu Sorel, a climatologist at Météo France.

Restoration projects awarded grants to convert defunct bogs to bring environmental benefits and restore wildlife

As millions of cranberries were being harvested for Thursday’s US Thanksgiving holiday, Massachusetts farmers were working to convert defunct cranberry bogs to back to wild wetlands, amid climate crisis woes.

Several restoration projects were awarded $6m in grants to carry out such initiatives, state officials announced this week.

Exclusive: National landscapes’ chiefs say environment secretary has given no budget assurances and they are to expect cuts

Proposed cuts to England’s most beautiful landscapes pose an “existential threat”, the managers of the National Landscapes Association have warned.

These 46 regions, including the Chilterns, the Cotswolds, the Wye Valley and the north Pennines, used to be known as areas of outstanding natural beauty but were renamed this year as “national landscapes”. They cover 15% of England, including 20% of the coastline.

Source of Philadelphia’s drinking water sees salt line pushed closer to city by drought and sea level rise

Salty ocean water is creeping up the Delaware River, the source for much of the drinking water for Philadelphia and millions of others, brought on by drought conditions and sea level rise, and prompting officials to tap reservoirs to push the un-potable tide back downstream.

Officials say drinking water is not imminently at risk, but they are monitoring the effects of the drought on the river and studying options for the future in case further droughts sap the area, amid the climate crisis.

Loyalists selected for important roles have offered staunch support to fossil fuels and downplayed climate crisis

Donald Trump’s cabinet picks have been eclectic and often controversial but a unifying theme is emerging, experts say, with the US president-elect’s nominees offering staunch support to fossil fuels and either downplaying or denying the climate crisis caused by the burning of these fuels.

Trump ran on promises to eviscerate “green new scam” climate policies and to “drill, baby, drill” for more oil and gas, and his choices to run the major organs of the US government echo such sentiments, particularly his picks relating to the environment, with Lee Zeldin chosen as the Environmental Protection Agency administrator, Chris Wright as energy secretary and Doug Burgum as interior secretary.

A parliamentary select committee has recommended insurance companies be forced to disclose insurance premium calculations amid a surge in the cost of household policies, especially for those living in and around areas prone to natural disasters.

The recommendation, one of eight flowing out of an inquiry into the impact of climate change on insurance premiums, comes during a period of rising stress for many homeowners who have received huge price increases in their renewal notices with little explanation.

Research reflects rising optimism about country’s green transition as it takes leading position on climate action

Nearly half of experts surveyed by a climate thinktank believe China’s carbon dioxide emissions have already peaked, or will do so in 2025, reflecting increasing optimism about the country’s green transition at a time when it is being called on to take a leading position on global climate action.

According to a report published on Tuesday by the Centre for Research on Energy and Clean Air (CREA), a research organisation, 44% of climate experts from academia and industry believe that China’s CO2 emissions will peak, at the latest, in 2025. In last year’s survey, only 21% of experts gave the same response.

The environmental harm caused by this shapeshifting, underregulated industry must be tackled

Local pushback against cruise ships in the world’s top tourist destinations is nothing new. More than three years ago, these vast vessels were barred from Venice’s lagoon on grounds of the risk they posed to the city’s historic buildings. This summer, cruise ships in Amsterdam and Barcelona were targeted by protesters, on grounds of chemical pollution but also as part of a wider movement against overtourism (as the negative impacts of huge influxes of visitors have become known). But – as revealed this week in a series of Guardian articles, The real cost of cruises – the environmental and social impact of this fast-growing industry goes way beyond individual cities, and requires action on a global scale.

The carbon emissions of a cruise are roughly double that of the equivalent flights plus a hotel stay. The industry is also responsible for a vast quantity of waste discharged directly into the sea, as well as high levels of toxic air pollution in the ports where ships are docked – usually with their engines running. Once seen as the exclusive pursuit of a minority of wealthy retired people, these holidays are now mainstream, with vast floating resorts designed and marketed for families and young adults. The largest ships have up to 20 floors and room for several thousand people.

The Australian government will claim it is on track to meet its legislated 43% emissions reduction target by 2030 after a departmental analysis found it had improved its position over the past year.

The government said annual emissions projections, based on an assessment of government policies and other trends, suggest national climate pollution would be at least 42.6% less than 2005 levels by the end of the decade, compared with 37% last year. The forecast included the impact of an underwriting scheme for new large-scale renewable energy and batteries, and vehicle efficiency standards that from next year require auto companies to start selling more zero and low-emissions cars.

It is only a matter of time before a mountainside is brought down. We need climate adaptation help – and we need it now

It’s “raining old ladies and sticks” is the Welsh equivalent of cats and dogs, and boy did those old ladies mean business when Storm Bert poured out nearly a month’s worth of rain on the Bannau Brycheiniog (Brecon Beacons) over Saturday night. By Sunday, the deluge was surging into the River Taff and through the Welsh valleys, forcing the Taff to burst its banks, bringing misery to communities along its length – including mine in Taff’s Well.

Neighbours, who had been devastated by Storm Dennis in February 2020, were shocked to find that everything they had done to rebuild was undone. Replastered front rooms were submerged yet again. New cars were bobbing once more in the streets.

A new generation is taking to the ocean in growing numbers – and fears over the environmental impact of cruise ships appear not to be denting their popularity

This summer was the first time 31-year-old Daisie Morrison had been on a cruise when she set sail on a two-week holiday with two friends, also in their early 30s.

“One of my friends suggested it,” she says. “She had seen different influencers on Instagram going on cruises. You go to so many places that we wanted to visit, so we were all quite keen.”

While an agreement on climate finance was eventually reached in Baku, many poorer countries were outraged

The Lamborghini showroom and a Tiffany branch sit at either end of Baku’s long boulevards beside the Caspian Sea. Adorned with grand 19th-century mansions, all plaster nymphs and columned facades, that were built by the first oil millionaires, they are a testament to the enduring power of fossil fuels. Oil has been very good to Azerbaijan.

It flows out of the ground here, and gas has seeped out, ignited and burned naturally in the area for so long that the country’s symbol is a flame and its nickname is the Land of Fire. Baku was the world’s first oil town, with wells exploited as early as the 1840s. Ilham Aliyev, the autocratic president, calls oil and gas “the gift of God” to his people. They represent 90% of Azerbaijan’s exports.

Madeleine Finlay hears from the Guardian’s environment editor, Damian Carrington, about the controversial climate finance deal that brought Cop29 negotiations to a close in the early hours on Sunday morning in Baku, Azerbaijan. Developing countries asked rich countries to provide them with $1.3tn a year to help them decarbonise their economies and cope with the effects of the climate crisis. But the final deal set a pledge of just $300bn annually, with $1.3tn only a target. Damian tells Madeleine how negotiations unfolded, and what we can expect from next year’s conference in Brazil
