The United Nations is warning that the world is on its way to "catastrophic" climate change, unless huge efforts are made to curb carbon emissions. It says the current goal of limiting warming to one-and-a-half Celsius above pre-industrial levels by the end of the century, will soon be dead. Current projections are closer to three degrees. We will speak to one of the authors of the UN report. Former president Donald Trump and vice president Kamala Harris have continued to attack each other as the US election draws closer. Immigration remains one of the major election issues and a top concern of American voters. Newshour's James Menendez has been travelling from Mexico to the southern United States to find out what's driving the debate. Also, grief and chaos for Palestinians as Israel predicts a ‘sharp conclusion’ in northern Gaza. We hear form a nurse, who filmed moments after an Israeli strike. And why the Foreign Minister of the Bahamas believes reparatory justice from the UK for the slave trade will happen at some point.

  • Hello, welcome to NewsHour.

  • It's coming to you from the BBC World Service Studios in London with me, Tim Franks.

  • And we'll also later in the program hear from my colleague James Menendez in San Anton.

  • We're going to begin with one of the UN Secretary General's favourite alarmist metaphors.

  • We are, he said today, playing with fire.

  • It is an apt image, given that he was talking in this case about the UN Environment Agency's annual report into how we're all doing in the effort to reduce greenhouse gas emissions.

  • Its sober conclusion, catastrophic, at least if we carry on with our current efforts, which leave us en route for an increase in global temperatures not within the target of 1.5 degrees above pre industrial levels, but 3.1 degrees.

  • We'll pick apart the figures and also try to explore how and why we shouldn't be despondent.

  • Let's begin, though, with the figures with our environment correspondent, Matt McGrath.

  • The emissions gap report has been produced for the last 15 years or so.

  • What it's been looking at is that amount of carbon produced in 2023 and seeing a significant increase now 1.3% mightn't sound like a huge increase, but it's much bigger than the preceding decade's average annual increase.

  • And what's driving it up in 2023 was the rebound from the COVID pandemic, more flying, more people driving, a range of industries kickstarting again.
