Critics said I was attacking motorists. It’s more important for me that the city’s children are no longer breathing dangerous levels of pollution Ulez led to better lung size and function among London children, study finds When I introduced London’s clean air zone – the ultra-low emission zone (Ulez) – more than seven years ago, no city had ever attempted anything quite like it. At the time, the scheme in central London provoked fierce opposition. When I decided to expand it – first in 2021, to inner London, and then again in 2023 to the whole city, making it the biggest clean-air zone in the world – my detractors were louder still. I had, they claimed, declared war on drivers in blind pursuit of a policy that may not even work. All the mainstream political parties, including my own, were opposed. In recent years, though, those critics have gone quiet. There is now a mountain of evidence to show that the Ulez has slashed air pollution and improved air quality across London, and research published by Imperial College London earlier this year showed that this is already saving lives. Between 2019 (when I first introduced the Ulez) and 2024, estimated deaths associated with air pollution in the capital fell by around 40%. But a new, independent study published by Queen Mary University of London today goes further still, showing how – by helping to clean up the capital’s air – the Ulez is improving the lungs and lives of London’s children.

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.” Continue reading...

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. Crow Leasow oak, Shropshire. Tea Party oak, Suffolk. King John oak, Devon.
