Chair of Nuclear for Australia denies that calling CO2 ‘plant food’ means he is a climate denier

Dr Adi Paterson’s statements are apparently at odds with the group’s official position, which says nuclear is needed to tackle the climate crisis

The chair of a leading Australian nuclear advocacy group has called concerns that carbon dioxide emissions are driving a climate crisis an “irrational fear of a trace gas which is plant food” and has rejected links between worsening extreme weather and global heating.

Several statements from Dr Adi Paterson, reviewed by the Guardian, appear at odds with statements from the group he chairs, Nuclear for Australia, which is hosting a petition saying nuclear is needed to tackle an “energy and climate crisis”.

Why do whales beach themselves? A vial of parasites in a Tasmanian museum may hold the answer

Pilot whale that beached itself in 1973 was infested with thousands of parasitic nematodes that may have eaten away at its blowhole

A vial of white parasitic worms left for decades in a Tasmanian museum may help solve a timeless mystery: why do whales strand themselves on beaches?

The worms were collected from the blowhole of a pilot whale that beached itself in 1973 and then stored in Launceston’s Queen Victoria Museum and Art Gallery.

‘The new reality’: Athens wildfire victims vow to adapt and stay put

People say they are determined and that prevention will be key to mitigating the effects of the climate crisis

“I used to talk to them every day.” Dimitris Petrou takes in the creatures that were once his fluffy chicks but now look like coals. The buckled cage with its carbonised birds is part of the cataclysmic scenery left behind by the fire that bore down on Athens after raging across the Attica plains consuming everything in its path.

The 72-year-old retiree and his wife, Frosso, though red-eyed and fatigued, are “somehow still going” but are profoundly shocked.

China adds new clean power equivalent to UK’s entire electricity output

Data shows continued surge in wind and solar power amid hopes Chinese greenhouse gas emissions may have peaked

China added as much new clean energy generation in the first half of this year as the UK produced from all sources in the same period last year, data shows, as wind and solar power generation continued to surge in the world’s biggest emitter of greenhouse gases.

Electricity generation from coal and gas dropped by 5% in China in July, year on year, according to an update from the Centre for Research on Energy and Clean Air (CREA) thinktank, basing its analysis on data released by the Chinese government on Thursday.

Canada’s 2023 wildfires produced nearly a decade’s worth of blaze emissions

Fires made at least three times more likely by climate crisis and emitted about 2bn tonnes of CO2, data reveals

Canada’s “record-shattering” wildfires last year produced nearly as much greenhouse gas emissions in one season as would be expected over a decade of fires in normal circumstances, data has shown.

The fires, in Canada’s “wildest season ever”, were made at least three times more likely by the climate crisis, and produced about 2bn tonnes of CO2, about a quarter of the total global emissions from wildfires last year, according to data in the State of Wildfires report, published on Wednesday.

Tuesday briefing: How Copenhagen is helping tourists go green

In today’s newsletter: As visitors overwhelm Venice, Barcelona and other famous cities, a model rewarding travellers for being more responsible could inspire other municipalities

Sign up here for our daily newsletter, First Edition

Good morning. Today we’re taking a little trip to Copenhagen to explore a new pilot initiative designed to reward tourists for “climate-friendly actions”. The CopenPay scheme has been designed to encourage visitors to act a bit more responsibly and think about their impact on the environment during trips to the Danish capital.

In return for small environmental actions – like cycling to attractions or fishing litter out of the canals – visitors have been rewarded with small gifts such as free ice-cream and museum tours.

Climate crisis | Hot weather inflamed by carbon pollution killed nearly 50,000 people in Europe last year, with the continent warming at a much faster rate than other parts of the world, research has found. Heat-related mortality was highest in Greece, with 393 deaths per million people.

Ukraine | Ukrainian forces have captured 1,000 sq km (386 square miles) of Russia’s bordering Kursk region, Kyiv’s top commander has claimed, as Vladimir Putin vowed a “worthy response” to the attack. 121,000 people have fled the region since the incursion began.

UK news | A shop security guard has described how he overpowered a knifeman as he stabbed an 11-year-old girl and her mother, 34, in a “horrific” and apparently random attack in London’s busy Leicester Square in front of shocked workers and tourists.

UK news | A “series of errors and misjudgments” in Valdo Calocane’s mental health care led to him being discharged, despite repeatedly not taking medication and showing signs of aggression, months before he killed three people in Nottingham, a report says. The Care Quality Commission warned of “systemic issues with community mental health care”.

Technology | Labour MPs have begun quitting X in alarm over the platform’s direction, with one saying Elon Musk had turned it into “a megaphone for foreign adversaries and far-right fringe groups”. Meanwhile, Donald Trump gave a rambling interview to Musk on the platform that was marred with technical issues initially preventing many users from watching the conversation.

Weather tracker: Storm Debby leaves power cuts and flooding in its wake

Meanwhile, a tropical disturbance in the Atlantic is likely to develop into a named storm within days

Storm Debby, which initially struck Florida as a hurricane, caused widespread destruction as it moved up the east coast, leaving many without power and dealing with severe flooding.

The storm brought significant damage across Ohio, New York, Pennsylvania and Vermont, with power outages affecting large areas days after the storm’s passage. In Steuben County in New York, heavy rain triggered flash flooding, leading to road closures and evacuations. In Pennsylvania, numerous water rescues were necessary as flood waters rose rapidly.

Pantanal waterway project would destroy a ‘paradise on Earth’, scientists warn

The South American wetland, which falls within Brazil, Bolivia and Paraguay, would be vulnerable to biome loss and increased wildfires

Dozens of scientists are sounding the alarm that carving a commercial waterway through the world’s largest wetlands could spell the “end of an entire biome”, and leave hundreds of thousands of hectares of land to be devastated by wildfires.

The Pantanal wetland – which falls within Brazil, Bolivia and Paraguay, covering an area almost half the size of Germany – is facing the proposed construction of a commercial waterway, as well as the expansion of industrial farming and spread of intense wildfires. A cohort of 40 scientists say the waterway development represents an existential threat to the ecosystem: reducing the floodplain, increasing the risk of fires and transforming the area into a landscape that could more easily be farmed.

Startling genome discovery in butterfly project reveals impact of climate change in Europe

Project to study all 11,000 species of butterflies and moths finds ‘two species in the act of being created from one’

The chalkhill blue has some surprising claims to fame. For a start, it is one of the UK’s most beautiful butterflies, as can be seen as they flutter above the grasslands of southern England in summer.

Then there is their close and unusual relationship with ants. Caterpillars of Lysandra coridon – found across Europe – exude a type of honeydew that is milked by ants and provides them with energy. In return, they are given protection in cells below ground especially created for them by the ants. Chalkhill blues thrive as a result, though their numbers are now coming under threat.

It looks like a cross between a koala and a possum – and it’s in big trouble, Australian conservationists say

Queensland Conservation Council is urging the state government to protect the endangered greater glider population as logging continues

There is “damning evidence” of logging occurring close to endangered greater glider populations, conservationists say as they call on the Queensland government to urgently act on a promise to create a park to protect the species.

Volunteers used drones in July to film logging in St Mary state forest near Maryborough, about three kilometres from where gliders had been seen.
