Good morning.

Humanity has failed to limit global heating to 1.5C and must change course immediately, the secretary general of the UN has warned.

In his only interview before next month’s Cop30 climate summit, António Guterres acknowledged it was now “inevitable” that humanity would overshoot the target in the Paris climate agreement, with “devastating consequences” for the world.

He urged the leaders who will gather in the Brazilian rainforest city of Belém to realise that the longer they delay cutting emissions, the greater the danger of passing catastrophic “tipping points” in the Amazon, the Arctic and the oceans.

• What does the UN say about world’s climate plans? Recently drafted climate plans from scores of countries fall drastically short of what is needed to stave off the worst effects of climate breakdown, analysis has shown.

Jamaicans have started to take shelter from Hurricane Melissa as the category 5 storm neared the coast, amid warnings of catastrophic flooding, landslides and extensive infrastructure damage.

The slow-moving giant, the strongest hurricane to hit Jamaica since records began in 1851, is due to make landfall early on Tuesday and to linger over the island.

The storm is expected to slice diagonally across the island, entering near the parish of St Elizabeth in the south and exiting around the parish of St Ann in the north, according to forecasters.

• What do forecasters predict? Some parts of eastern Jamaica could receive up to a metre (40in) of rain while western Haiti could get 40cm (16in), the US National Hurricane Center said. “Catastrophic flash flooding and numerous landslides are likely.”

Elizabeth Warren urges US regulators to investigate Jes Staley ties to Epstein

The Democratic senator Elizabeth Warren is calling for an investigation into bankers including Jes Staley over their alleged support for the convicted sex offender Jeffrey Epstein, in a move that could leave the former Barclays boss banned from working in the US financial sector.

In a letter privately filed with regulators, and seen by the Guardian, Warren called for investigations into “all current and former US banking executives who may have facilitated Jeffrey Epstein’s illicit conduct”.

• What was Epstein’s relationship with JP Morgan? During his 15-year relationship with JP Morgan, Epstein opened at least 134 accounts, processed over $1bn in transactions, and brought in several lucrative clients, Warren’s letter said.

• What did Warren say about Staley? That he is alleged to have helped protect the late financier’s access to the banking system during his stint working at JP Morgan in the early 2000s. Warren noted that Staley – who is already banned from the UK banking sector – had been described in media reports as Epstein’s “chief defender”.

Amazon is preparing to lay off tens of thousands of corporate workers, reversing its pandemic hiring spree. The cuts come months after its chief executive warned white-collar employees their jobs could be taken by artificial intelligence. The Amazon senior vice-president Beth Galetti wrote in a blog post that “this generation of AI is the most transformative technology we’ve seen since the Internet”, and added that Amazon need to be “organized more leanly, with fewer layers”.

“Nearly three years after OpenAI launched ChatGPT and ushered in a global frenzy over large language models (LLMs), chatbots are weaving themselves into almost every part of society in China, the US and beyond,” said Viola Zhou. “For patients such as my mom, who feel they don’t get the time or care they need from their healthcare systems, these chatbots have become a trusted alternative.”

Meanwhile, more than a million people every week show suicidal intent when chatting with ChatGPT, OpenAI estimates.

Or this: A third term for Trump would be unconstitutional. Here’s why

Donald Trump has declined to definitively say he will not seek an unconstitutional third term as US president. “I would love to do it: I have my best numbers ever,” the 79-year-old told reporters on Air Force One during a trip to Asia. The 22nd amendment states no person shall be elected president more than twice – but Trump allies could challenge it or seek a loophole. Will it be possible?
