Nearly three decades since the United Nations climate talks began, we take a look at what it has achieved when it comes to tackling climate change. We also look towards COP 28 taking place in Dubai and ask what progress can be made at the latest round of negotiations. It’s the only international negotiation on climate change and a unique opportunity to get agreement on how to best tackle global warming – but it has its critics as well as its fans.
