Scientists find ‘substantial ecological changes’ after greening initiative by major road in Melbourne, Australia

The benefits of urban greening initiatives are increasingly well documented: they can help mitigate the effects of urban heating, and improve physical health and mental wellbeing. And even small greening actions in cities can significantly improve local biodiversity, new research suggests.

Increasing the diversity of native plants in a single urban green space resulted in a sevenfold increase in the number of insect species after three years, Australian researchers have found.

Antarctica is experiencing disturbing changes – from missing winter sea ice to disintegrating ice shelves – and it’s almost certain things will get worse

After decades immersed in Antarctic science, I’ve learned that physical and biological changes rarely occur smoothly. More often than not, they unfold in sharp steps. Right now, Antarctica’s climate and ecosystems are experiencing disturbing changes.

Much of this winter’s sea ice is missing. A crucial ocean current is slowing down, and glaciers and ice shelves are disintegrating.

Changes in Antarctic and Southern Ocean environments are linked to, and influence, climate impact drivers globally.

Release plans approved by UN nuclear authority have caused outcry in China and concern for the reputation of Japan’s seafood

Japan is to begin releasing wastewater from the wrecked Fukushima Daiichi nuclear power plant from Thursday, in defiance of opposition from fishing communities, China and some scientists.

The prime minister, Fumio Kishida, has said that disposing of more than 1m tonnes of water being stored at the site is an essential part of the long and complex process to decommission the plant.

Report argues chickens should be kept in much smaller flocks and given more space

The industrial poultry farming sector needs to be radically restructured to stop the spread of bird flu, says a report that argues wild birds are victims rather than the main vectors of the disease.

Bird flu is spiralling out of control and being spread by intensive poultry farms, according toreport by the campaign group Compassion in World Farming (CIWF).

Falmouth sighting of cross between common and striped dolphins thought to be UK first

Rare hybrid dolphins have been spotted off the coast of Cornwall in what is thought to be a UK first.

The pair of cetaceans, seen in Falmouth, are a cross between a common dolphin and a striped dolphin.

Link to climate activism is seven times stronger for anger than it is for hope, say Norwegian researchers

Anger is by far the most powerful emotional predictor of whether somebody plans to take part in a climate protest, research suggests.

The study, which asked 2,000 Norwegian adults how they felt about the climate crisis, found the link to activism was seven times stronger for anger than it was for hope. The effects were smaller for other actions, but fear and guilt were the best predictors of policy support, while sadness, fear and hope were the best predictors of behavioural change.

Orchids are blooming early in the shade house at Cranbourne Royal Botanic Gardens this winter.

“We usually don’t see these warmer temperatures until early spring,” orchid conservationist Alex McLachlan said.

Australia is experiencing an unseasonably warm winter and experts are noticing some odd side effects in Australian flora. 'These warming temperatures are changing the way that plants would normally act and it can lead to decreases in population as there aren't enough pollinators out ready to pollinate the flowers,' explains orchid conservationist Alex McLachlan. Some orchid species, like the Caladenia valida, are flowering a month ahead of schedule at the Cranbourne botanic gardens in Melbourne

Weather ballon climbs to 5,300 metres before temperature falls to 0C amid late summer heatwave

A Swiss weather balloon had to climb to an unprecedented 5,300 metres (17,400ft) before the temperature fell to 0C (32F), meteorologists have said, as a late summer heatwave and wildfires continue to pummel swathes of continental Europe.

A man was found dead in a blaze raging north of Athens on Monday as the Greek government warned of an “extreme” risk of fire across the country, while more than half of mainland France was placed under an amber heat alert.

Archaeologists fear dangerous precedent if court approves new beach facilities at site of Phaselis on the Mediterranean coast

The construction of tourist facilities on two beaches that were part of the ancient city of Phaselis – a tentative nominee for Unesco world heritage status – has caused outrage at what is claimed to be the latest example of the Turkish culture ministry sacrificing heritage for tourism.

The Alacasu and Bostanlık beaches, on Turkey’s southern Mediterranean coast in the province of Antalya, were part of Phaselis, a Greek and Roman settlement thought to be the birthplace of Plato’s student Theodectes. Despite having ruins dating back to the second century BC, the beaches have never been subject to an archaeological dig.

The nation relies on tourism, yet many local people feel the right to enjoy these timeless places is being denied them

It was mid-August 1997; I was in my 20s and heading from Athens to the Aegean island of Sifnos with three friends. We hopped on a ship at the port of Piraeus and sailed out into the blue waters. Arriving late in the evening, we spent that first night on the beach, close to the port of Kamares.

It was bliss: the lapping of gentle waves a few metres away and the distant music from the bars as we gazed at the stars and the blazing meteors crashing through the atmosphere. You felt you were shedding your old skin like a reptile; it was painful and liberating; it was existential.

In the desert town of Rancho Mirage, close to Palm Springs, a city that typically gets around 4.6 inches (12 cm) of rain in an entire year could receive 6-10 inches from this one storm. "It's quite amazing. I've never seen anything like this. And the tropical storm hasn't even hit us yet," said one resident.

Kemi Badenoch wants gender-specific lavatories in new venues, but is it wise to release more excrement into our fatally compromised sewage systems?

There are important questions to be asked about lavatories, and Kemi Badenoch is certainly the Tory best suited to answering them. A report in the government’s Daily Telegraph mouthpiece announced that a new government initiative would see the equalities minister, Kemi Badenoch, appoint a Tory lavatories tsar, a task that would doubtless make her flush with pride. But the Independent then reported that the government had “distanced” itself from this appointment, for fear of increased bureaucracy, and also, presumably, across-the-board toilet tsar-based ridicule.

Apparently, Kemi Badenoch’s Tory lavatory tsar would have ensured that all new offices, schools, hospitals and entertainment venues have separate male and female lavatories; a big job and a massive piece of business. But our children’s generation seem largely ambivalent about gender identity, and the practical lavatorial considerations that come with it; first-wave feminists, in contrast, are understandably anxious that women’s hard-won recognitions are not, as they see it, eroded; meanwhile, some young women tell me they fear the loss of certified spaces in nightclubs and pubs for crying, vomiting up alcopops and avoiding young men; most young men, however, seem comfortable with the idea of urinating indiscriminately on the floor, while simultaneously passing wind, in any toilet, however Kemi Badenoch choses to designate the toilet’s gender.

Analysis of EU and US shows livestock farmers receive about 1,000 times more public funding than plant-based and cultivated meat

The “gigantic” power of the meat and dairy industries in the EU and US is blocking the development of the greener alternatives needed to tackle the climate crisis, a study has found.

The analysis of lobbying, subsidies and regulations showed that livestock farmers in the EU received 1,200 times more public funding than plant-based meat or cultivated meat groups. In the US, the animal farmers got 800 times more public funding.

Agency plans a ‘case-by-case’ approach that allows for flexibility, but critics say ‘this is not a new definition – it is a lack of definition’

The US Environmental Protection Agency (EPA) office responsible for protecting the public from toxic substances has changed how it defines PFAS for a second time since 2021, a move critics say they fear will exclude thousands of “forever chemicals” from regulation and largely benefit industry.

Instead of using a clear definition of what constitutes a PFAS, the agency’s Office of Pollution Prevention and Toxics plans to take a “case-by-case” approach that allows it to be more flexible in determining which chemicals should be subjected to regulations.
