The Climate Question BBC World Service

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

Ammonia has revolutionised the way we produce our food, helping us to grow much, much more... But it’s also helping to grow global greenhouse gas emissions too.
Synthetic fertilisers are actually responsible for around 5% of the planet-warming gases going into the air - that’s more than deforestation.
In this episode, Graihagh Jackson examines this challenge that modern agriculture poses to the climate, and finds out whether it’s possible to cut emissions from fertiliser use without cutting food production at the same time. She’ll also be joined by local reporters in Kenya to hear about innovative projects aiming to tackle this problem and turn farming green.

Delhi’s roads are being taken over by electric mopeds, scooters and rickshaws. More than fifty per cent of two- and three-wheelers are already electric, and the market is expected to continue growing. It’s good news for the fight against climate change. Why has the transition to green vehicles been so swift in India and what can the rest of the world learn from it?
Graihagh Jackson speaks to reporter Sushmita Pathak, who’s been chatting to those who’ve made the switch to electric as well as those who haven’t. Akshima Ghate from the RMI Foundation and Louise Ribet of C40 cities explain why these small vehicles are so popular and what countries like India and others gain from encouraging electric uptake. From better air quality and healthier children to energy security and manufacturing expertise, there are many benefits beyond mitigating climate change.

Every year, the great migration sees hundreds of thousands of wildebeest, gazelles, zebras and antelopes migrate from the Serengeti plains in Tanzania to the Maasai Mara in Kenya, in search of water and juicy grass. But rising temperatures and unpredictable weather are changing this epic animal journey dramatically. It’s the same for great white sharks, which are being spotted in areas where they’d never normally live.
Tanzanian safari guide Neema Amos takes us into the Serengeti to explain why the wildebeest migration is so important. And shark expert Trisha Atwood reveals how these changes affect not just the animals, but our fight against climate change itself.
Presenter Sophie Eastaugh is joined by:
Neema Amos, Safari Guide in Tanzania
Trisha Atwood, Associate Professor of Watershed Sciences at Utah State University
Joseph Ogutu, Senior Statistician at University of Hohenheim

The BBC’s Global Health Correspondent Tulip Mazumdar investigates how extreme heat fuelled by climate change is affecting pregnant women in India. New research shared with the BBC suggests that pregnant informal workers in Tamil Nadu who were exposed to high temperatures saw double the risk of stillbirth, premature birth, low birth weight and miscarriage.
Discussing her reporting from India with The Climate Question host and fellow mum Graihagh Jackson, Tulip hears the heart-breaking stories of women affected and explores simple solutions that would make their work in scorching agricultural fields safer.
