Giant sequoias are built to withstand ordinary fires, but recent extreme wildfires killed thousands of trees that had survived for centuries or even millennia. A new analysis of about 26,400 sequoias found that trees in areas treated with prescribed burns were nearly four times more likely to survive. Researchers estimate the controlled fires prevented about 1,900 deaths and could have saved thousands more if used across every grove.

Efforts to contain wildfire that has consumed an area of four times the size of Paris impeded by windy conditions
Europe wildfires live – latest updates
Authorities are battling to contain a huge wildfire near Bordeaux in south-west France that has consumed an area of land four times the size of Paris.
Efforts to extinguish the blaze in the Gironde region, where nearly 220,000 people have been evacuated, were hampered by windy conditions on Saturday night.

A notorious snake invasion that devastated Guam’s native birds may have succeeded because the reptiles carried hidden genetic advantages. Using advanced long-read DNA sequencing, researchers uncovered more than 19,000 large genetic differences in brown tree snakes, many concentrated in genes tied to immunity and smell. This overlooked diversity may have helped a population founded by only a few snakes survive inbreeding, adapt to a new environment, and multiply to extraordinary densities.

Allowing use of two neonicotinoids to combat crop-ruining disease will kill bees and reduce harvests, union says
Beekeepers and environmentalists in France have reacted furiously after parliament approved a bill reauthorising two banned pesticides scientists say can poison bees.
“There are no words to describe the frustration,” said Carolyn Bouguet, a beekeeper in Essonne, greater Paris. “Bee populations have already been badly compromised by climate change, new parasites and loss of habitat. And now this.”

Temperatures of 95-105F (35-40C) are expected, spanning Gulf of Mexico coast to the Great Plains and the midwest
About 70 million people in the US are set to face excessive heat advisories as dangerously hot temperatures scorch much of the country’s southern and central states.
The third major “heat dome” event to hit the US in the past month is gathering strength over the weekend, spanning a vast swathe of the country, from the Gulf of Mexico coast to the Great Plains and the midwest.

Exclusive: Blunder at Rosebank, UK’s biggest undeveloped oilfield, comes as government considers granting licence
Production at Britain’s biggest undeveloped oil and gasfield could be delayed for months after equipment from a rig was accidentally dropped in the North Sea, the Guardian can reveal.
Andy Burnham’s new government is under pressure from the fossil fuel industry to allow oil to be retrieved from the Rosebank site despite opposition from climate campaigners and some Labour MPs.

Footage shows the extent of the devastation caused by wildfires in Cenicientos, in the Madrid region of Spain, on Friday. Members of Spain's military emergency unit sought to contain the blazes in the Madrid region and in Cuevas de Cañart in the country's north-east. In France, dozens of firefighters battled flames threatening homes around the towns of Saumos and Sainte-Hélène in the south-west as a wildfire swept the nearby forest. The virulence of the wildfires, fuelled by high temperatures and the long-term effects of the climate crisis, caught fire crews and authorities off-guard in both countries

Meanwhile, in the UK, a blaze in the Cairngorms national park has been described as ‘very serious’ by Scotland’s first minister
Tell us: have you been affected by wildfires in Europe?
The French prime minister, Sébastien Lecornu, has requested the armed forces to deploy an Airbus A400M military transport aircraft earlier than originally planned to help tackle the major wildfires in Gironde, according to Le Monde.
The French newspaper reported the aircraft’s use was not originally expected until the end of the month due to the technical preparations and tests required beforehand.
While the fires raging across forests in France are a dramatic reminder of three successive heatwaves in as many months, the state of the country’s rivers provides another, no less worrying insight into the impact of extreme heat supercharged by the climate crisis.
The Loire, France’s longest river, is at a historical low, with the flow of some branches, including through the city of Orléans, reduced to a trickle between sandbanks. Two weeks ago, 16% of French rivers were reported to have dried up. A quarter of small streams were stagnant or had disappeared altogether, according to the national low water observatory. There has been little rain since.

Campaigners urge government to introduce right of access to water, particularly as heatwaves become more common
Almost three-quarters of riverbanks in England have no public access, according to data released by the Right to Roam campaign.
Across the country, the public cannot use riverbanks or gain access to the rivers themselves in most of the river catchments from the west of Cornwall up to the Tweed, which flows through northern England and Scotland.
