Campaigners call for urgent action after data shows almost all bird types reducing in abundance

Woodland birds are facing an accelerating decline in the UK, with species at risk of extinction if the government does not act, experts have said.

A potential environmental game-changer, agroforestry has so far been overlooked and under-incentivised according to a US farming group, but the upcoming farm bill is an opportunity to switch up the rules.

A British energy company has teamed up with a carbon market digital infrastructure provider to facilitate the sales of credits to its customers, including those generated from its own projects.

Thousands of specimens from the 1500s show huge changes to Bologna’s flora due to climate crisis and migration, say researchers

A collection of pressed flowers taken from the hillsides of Bologna 500 years ago is unlocking knowledge about how the climate crisis and human migration is changing landscapes in northern Italy.

Picked between 1551 and 1586 by the Renaissance naturalist Ulisse Aldrovandi, the 5,000 delicately cut and dried plants form one of the richest collections of its time.

Trash Free Trails’ report finds average of 41 pieces of litter a kilometre as calls grow for deposit returns scheme

Litter is blighting the UK’s footpaths, with an average 41 pieces found a kilometre, according to a major study. Particularly frequently found brands included Lucozade, Coca-Cola, Red Bull, Monster and Walkers.

The State of Our Trails report, conducted by Trash Free Trails, is the first UK study that aims to establish a scientific understanding of the environmental consequences of the tonnes of litter in our landscapes. It drew together more than 1,600 submissions by 4,500 volunteers and with the data the authors have estimated as many as 9.1m individual pieces of litter could be found across the UK’s 220,000km of public rights of way. The surveys took place between July 2020 and August 2023.

The time for alarmist messages is over, and the organisation could help unite people in positive action

• Rupert Read is co-director of the Climate Majority Project

Gail Bradbrook, co-founder of Extinction Rebellion, has been found guilty of criminal damage, after she broke a window at the Department for Transport in an ecologically motivated protest against HS2 in 2019.

The timing of Bradbrook’s verdict is almost exquisitely ironic. Five years ago last week, Extinction Rebellion was launched in Parliament Square. Back then, a principal term of criticism lobbied at XR was that it was “alarmist”. Five years on, it’s plainly visible that it was not.

‘Alarming’ new research warns of risk to British woodlands from disease, extreme weather and wildfires, unless ‘call to action’ is heeded now

UK forests are heading for “catastrophic ecosystem collapse” within the next 50 years due to multiple threats including disease, extreme weather and wildfires, researchers have warned, with trees dying on a large scale.

The study, published in the journal Forestry, was put together by a panel of 42 researchers, with 1,200 experts consulted. Lead author, Dr Eleanor Tew, head of forest planning at Forestry England and visiting researcher at the University of Cambridge, described the finding as “sobering and alarming”.

While Europe is battered by the climate crisis, governments must reassure voters that green costs will be fairly shared

“At a time when we should be accelerating action, there is backtracking … We are hurtling towards disaster, eyes wide open.” A few months ago, the UN secretary general António Guterres used these words to warn that the collective battle against the climate crisis is losing political steam. Guterres was right: the collective response is pitiful. But it’s not just the politicians.

Clear evidence of climate fatigue emerges from recent opinion polls on voting intentions in the next European parliament elections, in June 2024. While European green parties are expected to lose more than a third of their seats, rightwing climate-sceptic conservatives are expected to win big.
