Carbon dioxide concentration has increased by more than 10% in just two decades, reports World Meteorological Organization

The concentration of planet-heating pollutants clogging the atmosphere hit record levels in 2023, the World Meteorological Organization (WMO) has said.

It found carbon dioxide is accumulating faster than at any time in human history, with concentrations having risen by more than 10% in just two decades.

The harm to babies and mothers is one of the warnings being sent to Cop29 decision-makers by leading scientists

Miscarriages, premature babies and harm to mothers caused by the climate crisis are a “blind spot” in action plans, according to a report aimed at the decision-makers who will attend the Cop29 summit in November.

Potential collapse of the Amazon rainforest, vital Atlantic Ocean currents and essential infrastructure in cities are also among the dangers cited by an international group of 80 leading scientists from 45 countries. The report collects the latest insights from physical and social science to inform the negotiations at the UN climate summit in Azerbaijan.

Australasian Centre for Corporate Responsibility alleges Santos’s plan to reach net zero by 2040 is ‘little more than a series of speculations’

A world-first greenwashing case that seeks to hold oil and gas company Santos accountable for its net zero commitments began in the federal court today, brought by one of its own shareholders, the Australasian Centre for Corporate Responsibility (ACCR).

The organisation claims Santos did not have a proper basis for saying it had a clear pathway to reduce emissions by 26% to 30% by 2030 and reach net zero by 2040, which constituted misleading or deceptive conduct in breach of Australian corporate and consumer laws.

Study says harmful gases linked to heart and lung disease shave nearly two years off a person’s life

Gas stoves kill 40,000 Europeans each year by pumping pollutants into their lungs, a report has found, a death toll twice as high as that from car crashes.

The cookers spew harmful gases linked to heart and lung disease but experts warn there is little public awareness of their dangers. On average, using a gas stove shaves nearly two years off a person’s life, according to a study of households in the EU and UK.

Consumption of world’s wealthiest people also making it increasingly difficult to limit global heating to 1.5C

The high carbon emissions of the world’s richest 1% are worsening hunger, poverty and excess deaths, a report has found.

Owing to luxury yachts, private jets and investments in polluting industries, the consumption of the world’s wealthiest people is also making it increasingly difficult to limit global heating to 1.5C.

Conham River Park is home to a group devoted to protecting and promoting the use of the river

In a shallow valley populated by reddening ancient oak trees, the River Avon snakes along quietly – the grind of Bristol unknowingly just metres away.

Despite the falling leaves and temperature, a group of women tentatively step into the 12.5C waters of the Conham River Park in the east of the city for a midday swim – a ritual they all insist is not just a hobby but a way of life.

Pledge signed by scientists from nine countries reflects concerns that offsets generated from forest-related projects may not have reduced emissions

Carbon offsets used by corporations around the world to lower their reportable greenhouse gas emissions are “ineffectual” and “hindering the energy transition”, according to more than 60 leading climate change scientists.

A pledge signed by scientists from nine countries, including the UK, US and Australia, said the “only path that can prevent further escalation of climate impacts” was “real zero” and not “net zero”.

Researchers gain deeper understanding of bird migration in study that could have ‘profound’ implications for windfarms

The yearly travel plans of birds up and down Australia’s east coast have been revealed for the first time, using the same tool that tracks the weather – a development experts say could have “profound” implications for conservation as more windfarms are built.

Scientists have used weather radars to show that bird migration across eastern Australia occurs in structured patterns. While many Australian bird species are known to be seasonally migratory, scientists previously did not know to what extent a distinct system existed.

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”.
