Sea ice is melting fast, worsening the climate crisis, but a bold attempt to rethicken it is showing early signs of success

‘This would have been a wild dream a year ago,” says Andrea Ceccolini, standing on Arctic sea ice just a 4-mile snowmobile ride from the Inuit town of Cambridge Bay, northern Canada. To his left are sky blue ponds of meltwater created in the last few days by a sun that no longer sets in the high north summer. To his right, the sea ice is still a brilliant white, the light dusting of snow on top continuing to sparkle.

“It’s incredibly different, the boundary – I mean, you can point to it,” he says. The difference is the result of a bold geoengineering experiment being conducted by Ceccolini’s company, Real Ice, funded by the UK government.

‘I am going to fight on,’ said the PM. Perhaps his delusion was more deep-rooted than the others had feared

Shortly before he arrived in Évian at the beginning of the week, Emmanuel Macron set up a new WhatsApp group for world leaders. Keir Starmer wasn’t included. Call it the G6, if you like. The idea was to have a safe space to discuss how best to deal with the UK prime minister. Should they confront head-on that this was going to be his last G7? That next year’s outing would be an athleisure occasion with Andy Burnham (T-shirts just a tad on the small size)? Should they club together to buy him a leaving present? A French World Cup football shirt signed by all of them?

Or was it best not to mention it at all? Just proceed on the basis that this was a perfectly normal occasion and they would all soon be meeting again at another global get-together. Nothing to see here. A quick competition for a photo opportunity with President Zelenskyy, a few jokes, promises to make the world a better place and then everyone goes home without acknowledging that Keir is about to get booted out of their select club. At least Starmer was bringing his wife, Victoria. Maybe she would get to say a few goodbyes.

A sinister new tablet threatens the honest-to-goodness toys’ existence, but Buzz, Woody and Jessie’s big tech moral battle feels compromised

The fifth episode of the Toy Story franchise is as slick and smooth as you like, as glitchless as Toy Story 6 or Toy Story 7 might be … or will be. As a piece of family-entertainment content it has the unblemished sheen of a brand new smartphone. But at heart, it has gone dead. For all the intensive, high-energy creative work that has clearly gone into this film’s every frame, the jeopardy, the novelty, the ideas and the passion are lacking; the crucial Toy Story theme of mortality feels underpowered, and the film even calamitously loses its nerve with its own big idea – those squeamish about spoilers had better look away now – the sinister way addictive tech devices are undermining the imaginative play that kids once had with honest-to-goodness toys.

Here a creepy tablet device called Lilypad (voiced by Greta Lee) enters the children’s world, but ultimately proves to be capable of sentimental self-sacrificial heroism when it comes to their mental health. Really? At least Lots-o’-Huggin’ Bear, the villain from TS3, had the courage of his evil convictions.

Tuchel’s multicultural squad are less burdened by narrative than previous teams and can embrace the chance to live in the moment

Nice World Cup you’ve got there. Be a shame if something … happened to it. The opening acts of this bloated, roided-up summer tournament have been surprisingly fun, light and sparky.

Surprising, that is, if you’ve absorbed much of its doom-laden buildup. Football always does this. There is a reason this sport has become humanity’s great brain-wipe distractor ray, the tool of mega-brands and jumped-up administrators with a Football Jesus fetish. You can stretch it thin, loan it out to despotic regimes. But the games will still be good. Football remains an indestructible substance.

‘The studio wanted me to wear less. They wanted to see my muscles. But we were shooting outdoors in winter – and I had to put Vaseline on to keep my body heat in’

Cannon Films had the rights to Masters of the Universe and thought: “Let’s get this new guy. He’s blond, has good pecs … He can wield the sword.” I was convinced to do it but only very reluctantly – I didn’t want to play a toy. There was lots of excitement but also lots of worry. I’d been Soviet bad guy Ivan Drago in Rocky IV and now I was going to be this American hero. I was nervous and afraid people weren’t going to like it.

When UK mockumentary Alternative 3 tried to spook viewers that scientists were vanishing as part of a sinister space plot it succeeded. Today, the resulting conspiracy theory has even seen Trump’s government launch an investigation

Over the past few months, a strange story has been seeping into the mainstream media from the more excitable corners of Substack and YouTube. Its claim: scientists whose work related to aerospace and nuclear research are either dying or going missing. According to an influential report in the Daily Mail in March, the disappearances form a “chilling pattern”: two, for instance, had worked together at an air force laboratory. The implications, in some accounts, are Hollywood sinister, with scientists working on top-secret breakthroughs running into dark forces who wanted to get hold of what they knew – or ensure their silence. And it all seems to have something to do with what we used to call UFOs.

On examination, these claims collapse. The “scientists” actually worked in disparate fields, from chemical biology to plasma physics. Several were actually administrators. Two had retired. One died of natural causes; another in a shooting spree. In any case, as the debunker Mick West pointed out, the “US top secret-cleared aerospace and nuclear workforce” is around 700,000, so normal mortality rates would predict far more deaths over the 22 months concerned – about 4,000. Nonetheless, Congresspeople have been warning darkly of threats to “national security”. The Trump administration has launched an investigation into a phenomenon that is often said to go hand-in-hand with something called “Alternative 3” – whose origins might end up surprising Trump and co.

Shots fired within 500 metres of vessel near Isle of Wight amid heightened tensions between London and Moscow

A Russian warship fired warning shots within a few hundred metres of a British pleasure yacht sailing across the Channel on Tuesday morning amid a period of heightened tensions between London and Moscow.

The rare incident took place at 11.40am more than 20 miles south of the Isle of Wight and less than 40 miles north of Normandy, France, when the yacht, identified as the private vessel Bright Future, sailed close to the Admiral Grigorovich and ignored at least one warning.

• UK politics live – latest updates

Keir Starmer is leaving British troops underfunded and unable to carry out the operations he expects from them, according to scathing remarks delivered in parliament on Tuesday by three senior defence figures.

The prime minister came under fire in separate interventions from his former defence secretary John Healey, the former defence minister Al Carns and the country’s current senior military officer, Rich Knighton.

PM did not have bilateral meeting with US leader but says pair had ‘very productive’ conversations in group sessions

• Europe live – latest updates

Keir Starmer has denied being snubbed by Donald Trump at the G7 in France after the two did not have a bilateral meeting at the summit.

The prime minister, who did meet the US president in a series of discussions involving other leaders, said he had a series of “very productive, very good conversations” with Trump. He added that Britain was ready to play its “full part” in opening the strait of Hormuz after a peace deal between Iran and the US.

The countries are expected to sign a memorandum of understanding on Friday before proceeding to the next stage of talks
