The Michelin-starred restaurateur has signed an open letter demanding delivery of £15m to divert produce to food banks and soup kitchens

Chef Tom Kerridge is teaming up with charities to demand delivery of a promised £15m fund to divert fresh but unused food from farms to food banks and soup kitchens across the country.

Repeated promises have been made by former ministers to fund the food waste reduction scheme, which effectively compensates farmers for harvesting, storing and packaging the food that would otherwise head into landfill or animal feed.

Hundreds of health workers sign letter to General Medical Council calling for halt to suspensions as GP faces jail for activism

Hundreds of health workers have called on the General Medical Council to stop suspending doctors imprisoned for peaceful climate activism ahead of a trial which could see the first jailing of a working GP for a non-violent climate protest in the UK.

Two retired GPs have been suspended by GMC-convened tribunals this year after receiving short sentences for non-violent offences during Just Stop Oil and Insulate Britain protests in 2021 and 2022. The medical regulator did not express concerns about the doctors’ clinical capabilities but said their actions undermined public confidence in the profession.

Legions of young people are getting organised, skilling up, raising their voices and placing their bodies in the path of those who profit from our addiction

Not long before the Nazis murdered him, the Lutheran pastor and resister Dietrich Bonhoeffer wrote that “the ultimate test of a moral society is the kind of world it leaves to its children”.

That moral challenge is timeless. But with the climate emergency upon us, it has an unsettling new edge, and with that in mind, I’ve been preoccupied lately by the under-appreciated power of solidarity.

Climate Change Committee advised Ed Miliband to cut level by 81% but activists want bigger promises

Climate campaigners have urged ministers to make steeper cuts in the UK’s greenhouse gas emissions after the government’s statutory adviser on the climate gave its verdict on new targets.

The Climate Change Committee, which advises the government, has written to Ed Miliband, the energy secretary, to advise cuts of 81% in the UK’s emissions, compared with 1990 levels, by 2035, if emissions from aviation and shipping are excluded.

Councillor has reportedly suggested using pills to control gulls, but experts say it may not be ethical or practical

Their brazen chip-snatching, swooping and aggressive squawking has earned seagulls a reputation as the scourge of seaside towns, terrorising unsuspecting tourists and enraging residents alike.

And as the marauding birds have ventured inland and established urban colonies, towns have deployed spikes, netting and even birds of prey as deterrents. Now Worcester city councillors appear to be contemplating a new escalation in the battle: bird contraceptives.

Researchers criticised and gaslighted after sharing fears with Guardian say acknowledging feelings is critical to their work

Climate scientists who were mocked and gaslighted after speaking up about their fears for the future have said acknowledging strong emotions is vital to their work.

The researchers said these feelings should not be suppressed in an attempt to reach supposed objectivity. Seeing climate experts’ fears and opinions about the climate crisis as irrelevant suggests science is separate from society and ultimately weakens it, they said.

Subtle temperature difference between ‘ocean skin’ and water beneath found to drive more CO2 absorption

A sliver of cool surface water less than 2mm deep helps oceans absorb carbon dioxide, a British-led team of scientists has established after months of voyages across the Atlantic painstakingly measuring gas and temperature levels.

The subtle difference in temperature between the “ocean skin” and the layer of water beneath it creates an interface that leads to more CO2 being taken in, the scientists observed.

Biotech giant’s alleged comments come as world leaders at Cop16 discuss how to share benefits from genetic code discoveries fairly

AstraZeneca has said it may cut jobs at its UK operation if the government enforces a global push to make companies share profits derived from nature’s genetic codes, multiple sources have told the Guardian.

The alleged comments from the company came amid a concerted lobbying push by the pharmaceutical industry against the profit-sharing measures.

Leaders are eager to fill us with positivity, but research shows people in distress are more likely to take collective action

If despair is the most unforgivable sin, then hope is surely the most abused virtue. That observation feels particularly apposite as we enter the Cop season, that time of United Nations megaconferences at the end of every year, when national leaders feel obliged to convince us the future will be better, despite growing evidence to the contrary.

Climate instability and nature extinction are making the Earth an uglier, riskier and more uncertain place, desiccating water supplies, driving up the price of food, displacing humans and non-humans, battering cities and ecosystems with ever fiercer storms, floods, heatwaves, droughts and forest fires. Still worse could be in store as we approach or pass a series of dangerous tipping points for Amazon rainforest dieback, ocean circulation breakdown, ice-cap collapse and other unimaginably horrible, but ever more possible, catastrophes.

Citizen power forced Germany’s greenest city-state into a binding agreement balancing housing and nature

When Fritz Schumacher laid out his vision for Hamburg a century ago, the sketch looked more like a fern than a town plan. Fronds of urban development radiated from the centre to tickle the countryside, bristling with dense rows of housing. The white spaces in between were to be filled with parks and playgrounds.

Schumacher was Hamburg’s chief building officer in the early 20th century, and a pioneer of green cities with widespread access to nature. “Building sites emerge even if you don’t invest in them,” he warned in 1932. “Public spaces disappear if you don’t invest in them.”

Expert reminds owners ‘freeze it, don’t squeeze it’ when it comes to a tick, ideally with a tick-freezing spray from a chemist

Dog owners have been warned about a tick boom unfolding along Australia’s east coast, with some experts predicting an unusually bad season for furry friends.

Veterinary scientist and parasitologist Peter Irwin, an emeritus professor at Murdoch University, said the severity of a tick season was largely determined by the preceding weather, and last summer had been very hot and wet along the east coast”.

Means to stop catastrophic global heating exist, says UN chief, but political courage is needed to end world’s fossil fuel addiction

The huge cuts in carbon emissions now needed to end the climate crisis mean it is “crunch time for real”, according to the UN’s environment chief.

An unprecedented global mobilisation of renewable energy, forest protection and other measures is needed to steer the world off the current path towards a catastrophic temperature rise of 3.1C, a report from the UN environment programme (Unep) has found. Extreme heatwaves, storms, droughts and floods are already ravaging communities with less than 1.5C of global heating to date.

More than 30m homes are thought to contain lead paint, including nearly 4m where children under age of six live

Two weeks after setting a nationwide deadline for removal of lead pipes, the Biden administration is imposing strict new limits on dust from lead-based paint in older homes and childcare facilities.

A final rule announced on Thursday by the Environmental Protection Agency sets limits on lead dust on floors and window sills in pre-1978 residences and childcare facilities to levels so low they cannot be detected.

Pace of growth helps maintain renewable energy when weather conditions interfere with wind and solar

Faced with worsening climate-driven disasters and an electricity grid increasingly supplied by intermittent renewables, the US is rapidly installing huge batteries that are already starting to help prevent power blackouts.

From barely anything just a few years ago, the US is now adding utility-scale batteries at a dizzying pace, having installed more than 20 gigawatts of battery capacity to the electric grid, with 5GW of this occurring just in the first seven months of this year, according to the federal Energy Information Administration (EIA).

Just designating key areas will not meet 30x30 target on nature loss, study says, pointing to oil drilling in parks

Biodiversity is declining more quickly within key protected areas than outside them, according to research that scientists say is a “wake-up call” to global leaders discussing how to stop nature loss at the UN’s Cop16 talks in Colombia.

Protecting 30% of land and water for nature by 2030 was one of the key targets settled on by world leaders in a landmark 2022 agreement to save nature – and this month leaders are gathering again at a summit in the Colombian city of Cali to measure progress and negotiate new agreements to stop biodiversity loss.

Plant enthusiast Darren Williams made the discovery in Marys Creek State Forest just west of Gympie in Queensland. The male platypus was freshly killed, probably after what would have been a fierce struggle with the ambush predator. Williams and his companion Elliot Bowerman photographed the roughly 2-metre long carpet python with its jaw firmly clasped around the platypus before quickly moving on. 'We didn’t want to disturb the snake,' Bowerman said

RHS says ensuring access to green space as part of housebuilding push could make Britons healthier

Requirements for gardens and the planting of trees must be included in Labour’s planned new rules for housebuilders, green groups have said.

The government is drawing up its future homes standard for new developments and it is not yet clear what requirements there will be for green space.

US firm Wolfspeed and German car parts supplier ZF postpone plans over doubts over viability

A project to build a €3bn factory making microchips for electric vehicles once hailed as part of a “return of the industrial revolution” in Germany has been put on hold, as the crisis in the country’s hi-tech manufacturing industry deepened.

US company Wolfspeed and German car parts supplier ZF have postponed plans to build an EV chip factory, adding to problems caused by a delay to two large-scale factories by US chip giant Intel and potential factory closures being considered by German carmaker Volkswagen.

Danish political scientist Bjorn Lomborg told the US cable host its biggest threat was not the climate crisis, but do his claims stack up?

Instead of an existential crisis for species worldwide, or threatening to submerge entire Pacific nations and coastal cities where hundreds of millions of people live, or a phenomenon driving unprecedented heatwaves and wildfires, the climate crisis was characterised somewhat differently on major US cable show Real Time with Bill Maher.

Climate change was “a problem”, Danish political scientist Bjorn Lomborg told comedian Maher, but would only shave a few percentage points off global GDP by the end of the century and in any case, he claimed, by then people would be much richer anyway.
