Forecasters say ‘first meaningful rain for a long time’ will not reverse widespread drought conditions
Floods and drought could hit the UK at the same time this week, with heavy rain forecast to fall on hard, parched soil.
While some parts of the UK will have the “first meaningful rain for a long time” in the coming days, it will not reverse widespread drought conditions that have put pressure on wildlife, farmers, firefighters and water resources.

Scientists surprised to find all but two of 12 grizzlies were dead within a year of ‘feelgood’ release, unable to sustain their high-calorie diet and inclined to approach humans
The orphaned grizzly bear cubs were bulked up with a generous diet of roadkill, watermelon, dog food and snacks donated by the public. Their contact with carers was limited to two people. Then, after up to a year in rehabilitation, they returned home to the wilds of British Columbia.
“It’s a feelgood thing – people feel good when the cage opens,” says Dr Lana M Ciarniello, a bear specialist who tracked the Canadian yearlings in a recent study. There is a perception that bears will thrive in their natural habitat, she says. “The reality is they’re not followed up on.”

Officials have had to remove thousands of tons of sargassum from Florida’s beaches amid the climate crisis
Dealing with seaweed is the bulk of Chris Bumpus’s job during the summer. As chief of conservation for Miami-Dade county’s parks, recreation and open spaces department, Bumpus is in charge of cleaning sargassum off 17 miles (27km) of county beaches. But some days, the odds are stacked against him and his team.
More and more sargassum, a kind of floating brown algae, has been washing up on the beaches of south Florida, west Africa, the Gulf of Mexico and the Caribbean.

Woodland Trust says trees struggling in drought stress, with older ‘survivors’ disproportionately affected
England’s ancient oak trees are dying in the summer’s extreme heat and dry weather, according to the Woodland Trust, with trees and ecosystems unable to adapt fast enough to the changing climate.
The heatwaves across much of Europe this summer have had a notable impact on crop growth and plant health. To cope with the extreme conditions, many trees are undergoing “early autumn”, wilting and losing their leaves early.

Vegetable and grain growers call for urgent action, warning of ‘catastrophic’ harvests due to continent-wide drought
Successive intense heatwaves and an increasingly severe, continent-wide drought have left many of Europe’s farmers in an “unprecedented” crisis, with vegetable and grain growers in particular warning of “catastrophic” harvests.
French vegetable production is down by “a very significant extent” compared with previous years, French growers have said, with shortfalls put at 25% for courgettes, 35% for lettuces, 40% for peas, 60% for broccoli and 50% to 100% for artichokes.

From Aboriginal rock art to colonial encounters, sharks have been a figure of fear and fascination throughout the long human history of this continent
Is there a more primal fear among beach-goers than the shark? Although many more Australians drown each year at the beach than are killed by these creatures, it’s sharks that inhabit the jagged edges of our collective consciousness.
After a terrifying spate of bites earlier this year, calls for shark culls resurfaced. Ocean swimming and surfing didn’t seem quite the same healthy pursuits they had just months earlier.

Manufacturing company 3M knew more than 50 years ago that its firefighting products – including components in Pfas “forever chemicals” – could be hazardous to the health of humans and animals and damage the environment, the federal government has claimed in court documents.
In filings as part of its $2bn lawsuit against the multinational company, commonwealth lawyers said products sold to Australia were known to stay present in water and soil, were persistent in the human body and in animals, and contributed to conditions including reduced kidney function, alterations in immune function, effects on fertility and puberty and lower birth weight in babies.
