COP28: agreement calls for "transition away from fossil fuels"

Delegates at the UN Climate Change Conference have reached an agreement that - for the first time - calls on countries to "transition away from fossil fuels", although that doesn't include gas . . . We hear reaction from countries in the developed and developing worlds. And we ask whether the summit can be considered a success. Also in the programme: we board the night train from Berlin to Paris, revived after it was scrapped nine years ago; and we hear how brain tissue and technology are being brought together for the next generation of computers.(IMAGE: Sultan Ahmed Al Jaber, COP28 President and UAE"s Minister for Industry and Advanced Technology, bangs the gavel as he speaks following the 2023 United Nations Climate Change Conference (COP28), in Dubai, United Arab Emirates, 13 December 2023 / CREDIT: EPA / Martin Divisek)
