The tragic felling of the tree is making land managers reflect on how this barren landscape should look in future

Last Wednesday night, Britain was robbed of one of its best-loved trees. Mike Pratt, the CEO of Northumberland Wildlife Trust, describes the venerable, now-recumbent sycamore at Sycamore Gap on Hadrian’s Wall as a “totem tree; a touch point in the landscape”.

But the tree, standing alone in a national park, also reminded some of how nature-depleted England is. As environmentalist Ben Goldsmith said at the time: “That someone would have destroyed this iconic tree is beyond comprehension; but what’s even more shocking is that this was pretty much the only tree in that entire landscape. Our national parks can and should be so much better.”

Five people have been arrested after Just Stop Oil protesters disrupted a performance of Les Misérables at the Sondheim theatre in London’s West End.

During a performance of the song Do You Hear the People Sing? members of the Just Stop Oil group stormed the stage with banners to boos from the audience.

In a post on X, the group wrote: '4 people are locked to the stage of the French-revolution-themed show. Valjean steals bread to feed a starving child. How long before we are all forced to steal?'

Luca Locatelli, an Italian photographer, has been researching the circular economy: an economic model geared to the elimination of waste, involving the circulation of products and materials and the regeneration of nature. His photographs document stories, practices and initiatives in Europe inspired by the movement, and nature-based production solutions and processes which tackle socio-environmental issues

As our climate warms, urban trees will be needed more than ever. A study looks at how they can be protected

El Niño is officially under way and Australians are preparing for a hot spring and summer. Urban trees play a vital role in keeping cities cool, evaporating water to provide a natural form of air-conditioning, cooling air temperatures and reducing heat-related deaths by more than a third. But trees struggle with extreme heat. A study shows that simply planting trees isn’t enough; urban trees need continuing care.

Researchers investigated the impact of extreme heat on trees during Australia’s last major heatwave, in 2019 and 2020. They found species with large thin leaves, such as red maple, were particularly vulnerable to extreme heat, whereas trees with thicker leaves, such as ash and Chinese elm, were better able to regulate their temperature. The results, published in Global Change Biology, show that access to water is also crucial, with well-watered trees able to open their pores and evaporate water, preventing scorching of leaves.

Thinktank says rapid growth of wind and solar is near rate required if world is to hit 2030 target as part of 1.5C pathway

Carbon emissions from the global electricity sector may peak this year, after plateauing in the first half of 2023, because of a surge in wind and solar power, according to a climate thinktank.

A new report on global electricity generation found that the growth of renewables was so rapid that it was close to the incredibly fast rate required if the world is to hit the tripling of capacity by the end of the decade that experts believe is necessary to stay on the 1.5C pathway.
