Exclusive: British garden staple becomes plant most frequently reported as suffering in heat, charity reports
With their lush foliage and blooms which turn pink, purple or blue depending on the soil, hydrangeas are a firm favourite in Britain.
The shrubs bloom throughout summer and have historically thrived in the mild, damp British climate. But hotter summers and heatwaves such as the one hitting parts of England this week are putting the flower at risk in the south of the country, the Royal Horticultural Society (RHS) has warned.

Findings can inform conversations about global climate reparations and financing for mitigations, researchers say
Caribbean nations suffered $53.2bn (£40bn) of damage from climate-fuelled disasters between 2000 and 2024, research into the cost of the climate crisis to developing small islands has found.
The figure is more than 90% of the total $57bn in economic damage caused by floods, storms and drought across 39 developing island nations in the Caribbean, the Pacific, the Atlantic, the Indian Ocean and the South China Sea, according to a study by development thinktank ODI Global.

Ryder Williams, 16, saved a boy from drowning in Santa Cruz, California – the first rescue of his career
A rookie, teenage California lifeguard who saved a young boy from drowning amid massive waves – while a bystander recorded dramatic video – has spent his whole life preparing for such a moment, according to his father.
Ryder Williams, 16, said he refused to let go of the child because he knew the boy would almost certainly die if he did, the lifeguard’s father, Shane, recounted on Tuesday, three days after the pulse-pounding rescue.

Five years ago, I wrote an open letter asking climate scientists to speak out against fossil fuels. Now governments are in retreat, it is surely time to act
France and Spain race to contain huge wildfires before fresh heatwave begins
Such is the astonishing scale of the wildfires burning at the gates of Bordeaux and Madrid, that if they had happened 20 – even 10 – years back, they may well have shocked the world into taking action on the climate crisis. But like the proverbial frog in a pot of slowly heating water, we have become inured; not only to the ever more devastating impacts of climate breakdown, but increasingly to the actions needed to bring global heating to heel.
Even as more than 35,000 wildfires rage across the surface of our world, and as we continue to rewind our planet’s climate so it resembles hotter episodes from its distant past, governments and trading blocs are very deliberately turning away from climate action.

Authorities fear progress in containing the fires in the Gironde and Madrid regions may be set back by temperatures expected to hit the low 40s
in Brussels
The European Union’s crisis-management team is expecting difficult weeks ahead, fearing a further outbreak of wildfires in Italy and Greece as the summer goes on.
“A firefighter will focus on protecting people. They will focus on protecting houses, protecting a business, a company, because this is something that matters for all our society. And indeed, sometimes by focusing on that, they cannot extinguish fire, [as] they would do it if it would be just forest.
So this is new, this is worrying. And of course also, this means that we need to adapt our methods of fighting the fires.”

Biologists say cargo ships stranded in Gulf may carry highly potent invasive species around the world as trade resumes
The closure of the strait of Hormuz has created conditions for an extreme global biodiversity threat, with scientists warning that thousands of stranded ships could spread invasive marine species across the world’s oceans once they begin sailing again.
More than 1,500 commercial vessels have been stuck in the Gulf since the strategic waterway closed on 28 February after the outbreak of the US-Israel war on Iran. An international team of marine biologists said that with the stranded ships remaining motionless, their hulls were becoming encrusted with marine life – from microbes and algae to barnacles and other invertebrates – that could hitchhike to ports around the world when trade resumed.

Adopting organic free-range model in UK could lead to greenhouse emissions equivalent to 2,316,000 tonnes of CO2, study suggests
Organic eggs are twice as bad for the climate as eggs from chickens living in cages, research suggests.
According to the study, switching the UK’s entire egg production to an organic free-range model would lead to greenhouse gas emissions equivalent to 2,316,000 tonnes of CO2 (tCO2e), while production through a fully caged system would emit 1,184,000 tCO2e.

Federal-state stoush comes as rating agency warns that electricity bills could skyrocket

Queensland and the Northern Territory have rejected the federal government’s plans to mandate that AI datacentres use renewable power, rubbishing Anthony Albanese’s proposals to regulate the booming technology as “underdeveloped ideas that hand increased power to Canberra”.
The latest federal-state stoush on energy comes as S&P Global, the economic rating agency, warns that power use from datacentres could rise five-fold by 2035 to 10% of Australia’s total consumption, and that a mismatch between delivery timelines for datacentres and renewable projects could lead to energy bills skyrocketing.

New research linking the issue to Parkinson’s disease adds to the evidence of serious health repercussions from traffic volume and other sources
The roar of late-night traffic is not just annoying for those trying to sleep. It can also have profound effects on their health. A pioneering new study, published this month, has found a clear link between road noise and Parkinson’s disease. The research, which followed more than 3 million Danish participants, found a modest but consistent effect: for every 11.5dB rise in noise level, the risk of the degenerative disorder rose by 3% over the 18-year study.
The study adds to the growing body of evidence that auditory nuisance is associated with serious physical consequences. The European Environment Agency reported last year that more than 110 million people across the continent suffer high levels of health-damaging noise pollution, with physiological stress and sleep disturbance leading to 66,000 early deaths annually as well as heart disease, diabetes and depression. It found that the harm caused was greater than from secondhand tobacco smoke exposure.

Some have called for Nuremberg-style trials against big oil. But there are laws already on the books to describe companies’ conduct
The sky outside is hazy orange, and my five-year-old son is screaming bloody murder. “Sorry, buddy, we have to stay inside,” I say. “It’s not safe to breathe out there.” I had told him we’d be going to the beach today. Something inside me tears a little as I wonder how many promises he’ll see similarly broken in the coming years.
Far too many parents were forced to have some version of this conversation with their children this month, as smoke from record-breaking wildfires poured across the midwest and north-east. Some of them already had to tell their kids that their Fourth of July festivities were canceled because of the lethal heatwave that caused numerous mass casualty events earlier this month.
