Warmer weather has benefited some species in Britain, but others that rely on specific plants or habitats have struggled
“Insectageddon” has not occurred, but there has been a loss of butterfly diversity over the past half a century, according to the world’s largest insect monitoring scheme.
More than 44m butterfly sightings scientifically collected in Britain since 1976 show that of the 58 native species recorded, 33 species have declined and 25 have increased in number.

Analysis shows whales’ coda vocalizations are ‘highly complex’ and remarkably similar to our own
We may appear to have little in common with sperm whales – enormous, ocean-dwelling animals that last shared a common ancestor with humans more than 90 million years ago. But the whales’ vocalized communications are remarkably similar to our own, researchers have discovered.
Not only do sperm whale have a form of “alphabet” and form vowels within their vocalizations but the structure of these vowels behaves in the same way as human speech, the new study has found.

With a summer glut on cards, customers are being urged to use more energy when renewables are abundant
Great Britain is on the brink of a record-breaking summer for renewable energy, which could lead to the first periods of zero-carbon electricity in the history of the power system.
These green milestones are an important step towards the government’s goal of creating a 95% gas-free grid by 2030 to power the electric vehicles, heat pumps and greener factories that will help the UK to reach its climate goals.

Exclusive: Climate action blockers including Saudi Arabia, Russia and major fossil fuel firms set to make extra $234bn by end of 2026
The world’s top 100 oil and gas companies banked more than $30m every hour in unearned profit in the first month of the US-Israeli war in Iran, according to exclusive analysis for the Guardian. Saudi Aramco, Gazprom and ExxonMobil are among the biggest beneficiaries of the bonanza, meaning key opponents of climate action continue to prosper.
The conflict pushed the price of oil to an average of $100 (£74) a barrel in March, leading to estimated windfall war profits for the month of $23bn for the companies. Oil and gas supplies will take months to return to pre-war levels and the companies will make $234bn by the end of the year if the oil price continues to average $100. The analysis uses data from a leading intelligence provider, Rystad Energy, analysed by Global Witness.

Report by Common Wealth argues rest of the world should pay for country’s transition as reparative climate finance
Cuba could beat the US’s crippling energy blockade for ever with just an $8bn investment in renewable energy. And the rest of the world should pay for it.
Those are the bold claims of a thinktank analysis of the embattled socialist republic’s energy policy, which claims that Cuba could show its Caribbean neighbours the way to a green energy future.

Prof Yasuyuki Aono’s meticulous work charted shifting bloom dates as a marker of climate change
Even in his final months, he counted the days until the cherry blossoms. Prof Yasuyuki Aono of Osaka Metropolitan University spent his career gathering data on the spring flowering dates of cherry trees in Japan in what is one of the world’s longest climate records tracking a seasonal occurrence.
Using sources dating as far back as the 9th century, he revealed that cherry tree flowerings have occurred progressively earlier in recent decades – a now famous marker of climate change.

Trump’s EPA chief Lee Zeldin’s presence shows how much influence climate deniers now have, experts say
As scientists confirmed that March was the United States’ most abnormally hot month in recorded history, dozens of climate deniers gathered to promote misinformation and tout their newfound influence on federal policy.
At a conference hosted by the prominent science-denying thinktank the Heartland Institute last week, a crowd of mostly middle-aged men in suits claimed the world is finally waking up to the idea that the climate crisis does not exist.

Air pollution caused by wildfires is another blow to northern Thailand’s tourism industry as businesses suffer amid war in Iran
The Doi Suthep temple in northern Thailand is known for its spectacular views of Chiang Mai and the lush forested mountains that surround it. Over recent weeks, though, visitors can see little of the city beyond a thick cloud of grey haze.
Persistent wildfires have caused intense air pollution across the north of Thailand, forcing three provinces to declare emergencies and triggering spikes in pollution-related illnesses.

From peak-bagging to thru-hiking, Americans have turned traversing land into personal milestones. This wilderness ranger and Indigenous writer has witnessed it firsthand
Këmituxwe Éhènta Wehikiyànkw
You are walking in our old homeland
After spending 12 years backpacking some of America’s wildest trails as a wilderness ranger for the US Forest Service – and then losing that job to politics – last spring I set out for the Appalachian Trail (AT), the longest hiking-only footpath in the world.

We delve into the best stories on how sport is changing around the climate crisis, and what can be done to navigate a way forward
Nelson Mandela said: “Sport can create hope where once there was only despair.” Too optimistic? In 2026, almost certainly. Sport is still a common language, uniting unlikely groups like an all-powerful Esperanto, but it is in trouble.
The pitches we play on, rivers we swim, seas we surf, mountains we climb, parks we run in, air we breathe – all are being degraded by the burning of fossil fuels as the climate crisis turns the sporting landscape upside down.
