Underwater curtains and ice thickening divert attention from cutting fossil fuel use, warns climate research group
Proposals to fight the impact of the climate crisis at the poles, from giant underwater curtains to scattering glass beads across the ice, have been dismissed by a group of scientists as an “unimaginably expensive” and “dangerous” distraction.
Geoengineering, which includes blocking sunlight with airborne particles and thickening ice with pumped seawater, has become highly divisive among scientists. Its proponents argue that, with cuts in carbon emissions going far too slowly, exploring options for “emergency brakes” would be valuable.

South Australians living with asthma or other types of respiratory illness have been warned of a “potential risk” posed by a toxic algal bloom dominating the state’s coastline at a Senate committee inquiry into the natural disaster.
The Senate committee had its first public hearing on Tuesday, and heard there were now toxins in the bloom that could exacerbate asthma; that very little was known about the species in the bloom, and that even its cause was not fully understood.

Biggest insect survey in world finds UK’s hot summer led to increase in numbers of many species, but overall trends are still concerning
Top 10 most-sighted butterflies in 2025’s Big Butterfly Count – in pictures
Butterfly numbers have bounced back after the dismal summer of 2024, but the hottest summer on record delivered only an average number of the insects in the annual Big Butterfly Count.
More than 125,000 citizen scientists joined the biggest insect survey in the world this summer, counting an average of 10.3 butterflies in each 15-minute count in parks, gardens and green spaces across Britain.

The Greens senator says the fact South Australia's algal bloom is yet to be declared a national disaster reflects the need for a new set of criteria for climate disasters, as the Senate begins an inquiry into the toxic event.'If this had been on the northern beaches of Sydney or on Bondi, would it have taken so long for the government to respond?', Hanson-Young said. 'Frankly, I think it probably wouldn't have'

Defra says blanket ban on ‘destructive’ fishing practice disproportionate as MPs urge minister to reconsider
Seabed bottom trawling, described by the chair of a Commons committee as a “destructive” fishing practice, will continue in English marine protected areas (MPAs), the government has announced.
Despite having official designation as protected areas for creatures including dolphins, puffins and seahorses, damaging industrial methods are still allowed to take place.

Researchers studying the phenomenon found in 2024 there were between 14 to 17 coyotes on Angel island
For nearly a decade, Angel Island in the San Francisco Bay has been home to what the state parks describes as a “budding population” of coyotes. Late last month park workers got a fascinating glimpse at the animal’s journey to the island.
Angel Island staffers traveling by boat saw a coyote swimming along Raccoon Strait, and filmed it paddling across the deep waterway between the island and mainland Marin county. The coyote was about a quarter mile from shore and safely returned to the island, the park posted online.

An estimated 129bn were being used every month around the world at height of pandemic, with no recycling stream
The surge in the use of disposable face masks during the Covid pandemic has left a chemical timebomb that could harm humans, animals and the environment, research suggests.
Billions of tonnes of plastic face masks created to protect people from the spread of the virus are now breaking down, releasing microplastics and chemical additives including endocrine disruptors, the research found.

From Covid misinformation to climate denialism, understanding the divergent paths of Australia and the US can help us fight the powerful forces that threaten our world
As two scientists who lived through Australia’s black summer bushfires and the Covid-19 crisis in the United States, we have seen firsthand how science in modern societies is under siege from an even more insidious “antiscience virus” of weaponised disinformation that undermines our ability to confront these crises.
There are five primary, interconnected forces behind the assault on science and reason. We call them the “five Ps”: the plutocrats, the petrostates, the pros (eg paid promoters of anti-science), the propagandists and – with important exceptions – the media. Together they have generated a perfect storm of antiscientific disinformation that now threatens humanity.
