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? Presenter Jordan Dunbar talks to: Dr Rose Mutiso - Research Director Energy for Growth Hub Prima Madan – Director, Cooling & Energy Efficiency, International Natural Resources Defence Council, India Kofi Agyarko – Director of Renewable Energy and Energy Efficiency, Ghana Energy Commission Thomas Naadi – BBC Correspondent GhanaProduction Team: Ben Cooper, Octavia Woodward, Brenda Brown, Simon Watts Sound Design: Tom Brignellemail: theclimatequestion@bbc.comNOTE: The speech made by President Jimmy Carter mentioned in the programme, was made in 1977 not 1974, as stated.

Leading climatologist Dr Friederike Otto discusses climate attribution science, determining if extreme weather events are caused by man-made climate change. The podcast explores how this data aids disaster planning and fights climate change misinformation by politicians and journalists.

In this extra episode, Graihagh Jackson hears from our friends on BBC podcast The Global Story about a case that could change the history of climate activism.For nearly a decade, a group of elderly women argued that Switzerland’s weak climate policies violated their human rights. Their victory – the first of its kind in the European Court of Human Rights – sets a precedent 46 countries must now follow. The BBC's climate reporter, Georgina Rannard, has been covering the case for years. She shares the women’s personal stories with presenter James Reynolds, while climate lawyer Sophie Marjanac explains what it could mean for those seeking climate justice everywhere.The Global Story brings you trusted insights from BBC journalists worldwide.

Corals protect humans and sustain 25% of all marine life. But reefs are under threat from climate change, and mass bleaching events mean that some scientists estimate they could disappear by 2100. In this episode, Graihagh Jackson is joined by BBC CrowdScience presenter, Caroline Steel. We go to Puerto Rico to see how self-duplicating, carnivorous coral could be the solution. We also speak to the scientist who helped discover what was causing coral bleaching in the first place - back when climate change was commonly denied. Guests: Dr Ove Hoegh-Guldberg, Professor of Marine Studies at the University of Queensland in Brisbane Dr Stacey Williams, Executive Director at the Institute for Socio Ecological Research Presenters: Graihagh Jackson and Caroline Steel Producer: Octavia Woodward Production co-ordinator: Brenda Brown Editor: Simon Watts Sound Engineer: Tom Brignell Got a climate question you’d like answered?
