Telecoms entrepreneur says continent’s people should be allowed to use their vast reserves

One of Africa’s richest entrepreneurs, the telecoms billionaire Mo Ibrahim, has criticised developed countries for seeking to dissuade African nations from exploiting their vast reserves of gas.

Ibrahim told the Guardian in an interview: “We need a balanced and a fair policy for everybody. Gas can be useful to our transition … [Those who say otherwise] are hypocrites.”

Climate crisis may explain fights as disappearing ice fuels interspecies competition – with goats nearly always winning

In one corner, there is the agile climber with steak knife-like horns. In the other is America’s largest wild sheep. They are locked in significantly one-sided combat in the mountains of the US west, scientists have found, in a battle over resources uncovered by the region’s vanishing glaciers.

In study sites across a 1,500-mile span of the Rocky Mountains, scientists have documented mountain goats and bighorn sheep competing over mineral deposits among the rocks, at elevations of up to 14,000ft.

Exclusive: investigation by charity WildFish says firms are avoiding mandatory reporting of sea lice

The Scottish farmed salmon industry is using loopholes to cover up evidence of environmental harm, poor animal welfare and high levels of disease, an investigation has found.

Using open data, investigators from the charity WildFish allege salmon farms are avoiding mandatory reporting of sea lice prevalence in fish to cover up the scale of parasite infestations, which in some cases are more than 20 times those stipulated in the industry’s own code of good practice.

Waterways across northern Victoria are peaking, with towns along the banks of the Goulburn and Campaspe rivers flooding or in danger of being inundated. Major flooding has peaked at Shepparton and Murchison, where the Goulburn reached 12 metres. It has also hit communities along the Avoca River to Charlton. More than 60 warnings have been issued across the state

Thames and Southern worst in England and Wales, as complaints to Thames on bills, sewerage and supply double in five years

Thames Water is at the top of a league table charting the number of written complaints made to water firms in England and Wales last year, with the number more than doubling since 2017.

The number of written complaints received by the firm from household customers has risen from 17,039 in 2017/18 to 40,060 in 2021/22, according to the most recent figures from the Consumer Council for Water (CCW). The firm accounted for nearly half (47%) of all written complaints to water and sewerage firms in England and Wales last year.

Only 5% of species now expected to survive as disease hits harder than first thought and prevention costs mount

Warburg Nature Reserve is one of the gems of the Chiltern Hills. In the autumn, its beech, birch and oak trees are transformed into a blazing canopy of red, yellow, brown and golden leaves. Buzzards and red kites swoop overhead while a startling array of fungi – from milkcaps to collared earthstars – push up through the woodland floor of the 100-hectare site.

This curtain of multicoloured delights hides a grim secret, however. A stroll through the reserve, which is owned by the Wildlife Trusts, reveals gaps that have recently appeared in the foliage.

One in five swimming spots in New South Wales have been rated as having “poor” or “very poor” pollution levels, including Sydney’s popular Coogee beach, after the state experienced its wettest summer in a decade.

Twice the number of beaches, lakes and lagoons have been exposed to concerning levels of pollution and sewage since 2019, according to the annual state of the beaches report released by the NSW Department of Planning and Environment.

New research has proposed a cost-effective way to recycle solar panels to help handle an increasing volume of retired photovoltaic (PV) cells expected by the end of the decade.

In a paper published by a team from the University of New South Wales last week, researchers outlined a process to collect and extract valuable materials from solar arrays to see if it was technically, economically and environmentally feasible.

Scorching summer left reservoirs depleted and unlikely to recover, as growers warn of supply chain collapse in leaked meeting

Farmers have warned they will not be able to grow crops next year if predictions that the drought will last until next summer prove accurate.

Leaked slides from a national drought group meeting, seen by the Observer, show there are concerns that because reservoirs are still empty due to record dry conditions, the fruit and vegetable supply chain could collapse.

A Louisiana power company’s plan to capture climate emissions is raising concerns about the state’s water supplies

A carbon capture proposal for a central Louisiana power plant has been titled “Project Diamond Vault” by its owner, Louisiana utility Cleco. The utility says the project will have “precious value” to the company, customers and state.

Yet less than six months after announcing the project to capture carbon from the plant’s emissions and store them underground near the plant, Cleco revealed in a recent filing to its state regulator the $900m carbon capture retrofit could reduce electricity produced for its customers by about 30%.

Exclusive: critics say stripped-down Environment Agency has not levied a fine in 12 years so no point to higher cap

The government’s pledge to raise the cap on the amount of money the Environment Agency can fine water companies for sewage pollution to £250m has been described as “hot air”, as the Guardian can reveal the regulator has failed to levy any such penalties since it was given powers to do so 12 years ago.

Variable monetary penalties (VMPs) were introduced in 2010 to enable the Environment Agency to directly levy fines for serious environmental offences without having to go through expensive and lengthy court proceedings, but to date the agency has not levied a single VMP against water companies.

Alok Sharma’s intervention puts pressure on Trump-appointed Bank chief who faces calls to resign

The UK has joined calls for sweeping reforms to the World Bank, to focus much-needed funding on the climate crisis, warning that its current structures are not working.

The intervention from Alok Sharma, the current president of the UN climate talks, heaps further pressure on beleaguered World Bank chief, David Malpass. He has faced calls to resign over an apparently climate-dismissing stance, and the Bank’s perceived failures to deliver climate finance.

Though there is situationist wit in throwing soup over Van Gogh’s Sunflowers, the protest is more likely to provoke eye-rolls than action

If you’re going to make a political statement by attacking an artwork then pick a big one. In the absence of the Mona Lisa, Just Stop Oil protesters today threw soup over one of 19th century’s most recognised images – immortalised on biscuit tins and tea towels the world over – Van Gogh’s Sunflowers. The National Gallery attack is the latest in a campaign that saw them glueing themselves to a reproduction of Leonardo da Vinci’s painting The Last Supper in the Royal Academy in July.

Such assaults are now so common that the Mona Lisa – most recently pelted with cake at the Louvre in Paris back in May – now smiles on from behind a pane of bullet-proof glass. The sunflowers themselves are unlikely to have suffered any damage, beyond the indignity of being eclipsed by a brighter shade of orange. The protesters will have known this, and there is a certain situationist wit in their choice of weapon – not a spray can but a tin of Heinz tomato soup, as immortalised by Andy Warhol, in the pop artist’s critique of exactly the sort of industrialisation that Just Stop Oil sees as responsible for the destruction of the planet.

Rainfall levels have not been sufficient to dampen soil and refill reservoirs after scorching summer

England could be in drought beyond spring 2023, ministers have said, after record low rainfall has left the country short on water.

The news will be particularly problematic for farmers, who were hoping for a damp autumn and winter to refill reservoirs so they could plant and harvest crops into next year.

Protesters then glue themselves to wall beneath painting at National Gallery in London

Activists from Just Stop Oil have thrown tomato soup over Vincent van Gogh’s Sunflowers at the National Gallery in London.

There were gasps, roars and a shout of “Oh my gosh!” in room 43 of the gallery as two young supporters of the climate protest group threw the liquid over the painting, which is protected by glass, just after 11am.

Plants damaged by extreme temperatures are most at risk of disease, Royal Horticultural Society says

Summer’s prolonged droughts and extreme heat have made plants more susceptible to problems such as fungi and insects this coming autumn, the Royal Horticultural Society has warned.

Plants stressed or damaged by the heat are most at risk of disease, but the charity’s experts say gardeners should also look out for specific plants that are typically more vulnerable such as tomatoes.

Failure to address country’s abuses will obstruct rollout of meaningful climate action, director of Human Rights Watch says

The Egyptian regime has successfully silenced the country’s independent environmentalists in the run-up to hosting this year’s UN climate talks, as part of a wider strategy to repress human rights that also threatens to derail meaningful global climate action, according to a leading advocate.

In an interview with the Guardian, Richard Pearshouse, environment director at Human Rights Watch, said failing to address abuses by Egypt and other authoritarian regimes will obstruct the rollout of ambitious climate policies needed to transition away from fossil fuels and curtail global heating.
