Simon Stiell insists it is vital governments regulate the technology to blunt its dangerous edges

Harnessing artificial intelligence will help the world to tackle the climate crisis, but governments must step in to regulate the technology, the UN’s climate chief has said.

AI is being used to make energy systems more efficient, and to develop tools to reduce carbon from industrial processes. The UN is also using AI as an aid to climate diplomacy.

Deal will involve two transactions – OpenAI will pay Nvidia for chips, and the chipmaker will invest in the AI start-up

Nvidia, the chipmaking company, will invest up to $100bn in OpenAI and provide it with data center chips, the companies said on Monday, a tie-up between two of the highest-profile leaders in the global artificial intelligence race.

The deal, which will see Nvidia start delivering chips as soon as late 2026, will involve two separate but intertwined transactions, according to a person close to OpenAI. The startup will pay Nvidia in cash for chips, and Nvidia will invest in OpenAI for non-controlling shares, the person said.

If machines become superintelligent we’re toast, say Eliezer Yudkowsky and Nate Soares. Should we believe them?

What if I told you I could stop you worrying about climate change, and all you had to do was read one book? Great, you’d say, until I mentioned that the reason you’d stop worrying was because the book says our species only has a few years before it’s wiped out by superintelligent AI anyway.

We don’t know what form this extinction will take exactly – perhaps an energy-hungry AI will let the millions of fusion power stations it has built run hot, boiling the oceans. Maybe it will want to reconfigure the atoms in our bodies into something more useful. There are many possibilities, almost all of them bad, say Eliezer Yudkowsky and Nate Soares in If Anyone Builds It, Everyone Dies, and who knows which will come true. But just as you can predict that an ice cube dropped into hot water will melt without knowing where any of its individual molecules will end up, you can be sure an AI that’s smarter than a human being will kill us all, somehow.

London-based AI pioneer in talks to receive $500m investment from Nvidia as it funds its expansion in the US, Germany and Japan

British startup Wayve has begun testing self-driving cars with Nissan in Japan ahead of a 2027 launch to consumers, as the company said it was in talks for a $500m investment from the chip-maker Nvidia.

Wayve, based in London, said it had installed its self-driving technology on Nissan’s electric Ariya vehicles and tested them on Tokyo’s streets, after first agreeing a deal with the Japanese carmaker in April.

TBI says poll data threatens Keir Starmer’s ambition for UK to become artificial intelligence ‘superpower’

Nearly twice as many Britons view artificial intelligence as a risk to the economy than regard it as an opportunity, according to Tony Blair’s thinktank.

The Tony Blair Institute warned that the poll findings threatened Keir Starmer’s ambition for the UK to become an AI “superpower” and urged the government to convince the public of the technology’s benefits.

US president tells Fox News ‘a man named Lachlan is involved … that’s a very unusual name, Lachlan Murdoch’

Rupert Murdoch and his son Lachlan Murdoch will probably be part of a group of investors that will buy TikTok , Donald Trump said in an interview on Sunday.

The president was asked about the status of the sale of the app during an interview with Peter Doocy on The Sunday Briefing on Fox News. Trump administration officials have signaled that a deal for the Chinese-owned social media platform was imminent, though there has been some confusion about the status of the agreement.

Amid the feathered dancers at an adult industry event, regulators with clipboards have been advising compliance

Three Ofcom regulators with clipboards spent the weekend making their way around the exhibition floor of an international adult industry conference in Prague, trying to encourage the 1,700 delegates to comply with the UK’s new Online Safety Act .

“Don’t lie to us,” one of the regulators told a room full of pornography site owners and employees during a lunchtime presentation explaining the new age verification requirements introduced in July as part of the act’s measures to stop children seeing pornography. “Be honest and open. If your measures are not good enough yet, put that on your risk assessment.”

Dyson’s upgraded Airwrap promises faster results and smarter tech. Here’s what it gets right – and where it falls short

• The best hot brushes for a salon finish at home, tested

Once best known for its floor cleaners and hand dryers, Dyson has carved out a space in the electrical beauty market over the past decade. Its Supersonic hair dryer was followed by the Airwrap multi-styler, a revolution in hair styling that uses air rather than direct heat to curl hair – and regularly sells out in stores worldwide despite its high price.

There have been two updates to the Airwrap since – a 2022 upgrade and the app-driven Airwrap id , which launched last year with variants for both curly and straight hair. This summer’s Co-anda 2x is a completely re-tooled product, with a more powerful motor for faster styling, and new attachments, including an air-powered straightener. I tested the new model to find out if it could really be worth £580.

Child safety watchdog calls for child protection guidelines to be built into AI models from the outset

A chatbot site offering explicit scenarios with preteen characters, illustrated by illegal abuse images has raised fresh fears about the misuse of artificial intelligence.

A report by a child safety watchdog has triggered calls for the UK government to impose safety guidelines on AI companies, amid a surge in child sexual abuse material (CSAM) created by the technology.
