Are we spending enough on renewable energy‪?‬ BBC World Service

Billions of dollars have been pumped into the promise of a climate-friendly way of producing meat, but is growing a steak in a lab any better for the planet than rearing a cow on a farm?
Supporters of the idea say it will dramatically reduce the impact of livestock, which is responsible for about 15% of the world’s planet-warming gases, as well as returning huge amounts of land to nature. But studies suggest cultivating meat in a lab might actually be worse for the planet, at least in the long-run – we put both claims to the test.
Graihagh Jackson presents an update of a programme first broadcast in 2023.
Guests:
Tasneem Karodia, co-founder of Mzansi Meat, in South Africa;
John Lynch, postdoctoral research associate at the University of Oxford, in the UK;
Nick Marsh, the BBC’s Asia business correspondent, in Singapore
Producer: Simon Tulett
Researcher: Matt Toulson
Series Producer: Alex Lewis
Editor: China Collins
Sound engineer: Tom Brignell
Production Coordinators: Debbie Richford and Sophie Hill

Graihagh Jackson is joined by her regular panel to answer climate-related questions from listeners. BBC climate editor Justin Rowlatt, Prof Tamsin Edwards of King's College London, and Dr Akshat Rathi, senior climate reporter for Bloomberg News, discuss telling children about climate change, solar panels, nuclear fusion and more.
Plus, Graihagh finds out if playing music really helps plants to grow.

China is scouring the globe for the raw materials of the future. How will we be affected? Graihagh Jackson investigates.

Today, more than half the world’s population live in cities – and as our numbers swell, so will our cities, especially those around the Pacific Rim, where it’s predicted our largest megacities of 10 million plus will be situated. And herein lies an opportunity: 60% of the buildings needed for 2050 are not yet built.
Could we shape our cities into places that are good for the climate and also good for our mental health? Can we design buildings and infrastructure that make green decisions easier and also help us deal with stress or depression?
Jordan Dunbar hears about examples in the Netherlands and Egypt. Are there win-win options out there that can help the world deal with two of its biggest challenges?

Experts say we need to be 40 per cent more energy efficient to meet our climate goals. Is that doable? And might it save us money too?
It's a solution that's been called the main route to net zero: energy efficiency - or using less energy to get the same or better results. But there’s an issue – it's got an image problem as many people think it’s boring. And it is hard to get excited about the idea of better lightbulbs!
But energy efficiency could save us money on our bills too - especially in a warming world, where many countries will need air conditioning just to function. So does this crucial area in the fight against climate change need a rebrand. And could it even become sexy?

NOTE: The speech made by President Jimmy Carter mentioned in the programme, was made in 1977 not 1974, as stated.

In this episode, Graihagh Jackson explores the new field of climate attribution science with leading climatologist Dr Friederike Otto. Dr Otto's team of experts can now rapidly assess to what extent extreme weather events such as heatwaves, droughts or floods have - or have not - been caused by man-made climate change.
Graihagh finds out how this information is becoming crucial for disaster planning and response. She is also joined by BBC World Service disinformation reporter Jacqui Wakefield to discuss how Dr Otto's data can help fight a growing tendency by politicians and journalists to overstate the role of climate change.
