The Climate Question

The American lawyer, oil lobbyist and master strategist Don Pearlman is said to have chain-smoked his way through almost every UN climate gathering from the early 1990s until his death in 2005.

Some of those who saw Pearlman operate in Kyoto, where the first legally binding international agreement on climate change was agreed in 1997, say he created the playbook for stalling climate talks. The Kyoto protocol was never ratified by th...

Carbon dioxide is a molecule so important it has shaped life on Earth for billions of years. Without it, there would be no plants, no oceans, no people. But now, after centuries of burning coal, oil and gas, it's in the atmosphere at levels that alarm scientists.

In this episode of The Climate Question, Graihagh Jackson speaks to Peter Brannen, science journalist and author of The Story of CO2 is the Story of Everything, and Esme St...

Every year, tens of thousands of people — from world leaders to activists to celebrities— gather for one of the world’s most ambitious meetings: the UN’s annual climate summit, COP.

But what does it actually take to make it happen? How do you feed, transport and house 80,000 people, while trying to keep global negotiations on track?

The Climate Question hosts Graihagh Jackson and Jordan Dunbar talk to Helen Wright, who helped deliver...

The Amazon is probably the most famous rainforest on Earth. It’s home to Indigenous communities, one of the world's biggest rivers and a diversity of plant and animal life found nowhere else. But it’s also a region rich in sought-after resources — gold, iron ore, bauxite, coffee and rubber — and vast areas of forest have been cleared for cattle and soy production. Scientists warn that deforestation and climate change are drying ...

BBC Climate Editor Justin Rowlatt travels to Somalia to investigate the links between global warming and the decades-long conflict there. He hears how Somalis are responding by launching businesses and their own renewables industry. This programme was first broadcast in 2024.

Presenter: Justin Rowlatt Producer in Somalia: Stuart Phillips Producers in London: Miho Tanaka, Sara Hegarty Sound Mix: Tom Brignell and David Crackles Editor...

Mumbai is India’s economic engine, but every rainy season this megacity comes to a virtual standstill as torrential rains flood streets, homes and transport networks. In 2005, Mumbai faced one of its worst floods on record – and experts warn that climate change could make future rainfall even more intense.

This week, Graihagh Jackson and Jordan Dunbar explore what’s happening with Mumbai and the mighty monsoon – and how a city of mo...

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...

What can ice cores tell us about the atmosphere millions of years ago?

These cylinders of ice, drilled from glaciers and ice sheets around the world, preserve precious clues about our changing climate and records such as rainfall, temperature and greenhouse gases, even volcanic eruptions. But what can the past tell us about the future?

Host Graihagh Jackson hears from two ice core experts about their icy adventures in Antarctic...

Geothermal energy is renewable, reliable and powerful. So, why is most of it untapped? That’s what our listener, Anna in the UK, wants to know. Full disclosure, she’s a geologist and is thoroughly perplexed by the lack of uptake. Geothermal is renewable, reliable and abundant and yet, less than 1% of the world’s energy is generated from it. Host Graihagh Jackson hears about a team in Iceland who hope to "super-charge" geothermal...

Graihagh Jackson and the BBC’s former Global Health Correspondent Tulip Mazumdar investigate how extreme heat, fuelled by climate change, is affecting pregnant women in India. In the southern state of Tamil Nadu, Tulip hears the heart-breaking stories of some of the women affected and explores simple solutions that would make their work in scorching agricultural fields safer. The programme was first broadcast in 2024. Ema...

When people talk about tipping points in the climate, it’s usually bad news – the irreversible melting of ice sheets or the collapse of rainforests. But could there be positive tipping points too, moments where climate solutions break through and spread rapidly?

Tim Lenton, Professor of Climate Change at the University of Exeter and author of Positive Tipping Points: How to Fix the Climate Crisis, says it’s already happening – from ...

Africa gets a world beating amount of sunshine — but has just 1% of the world’s solar panels.

Over half the continent still lives without electricity, stalling progress and holding back people’s lives. But change may be coming — thanks to a surge in solar imports from China.

New data from energy think tank EMBER shows a 60% jump in solar panel shipments to Africa in the past year. If installed, they could generate 15 GW — nearly do...

The world's wetlands store carbon and can help us tackle some of the impacts of climate change. Are we overlooking their importance? And what can we do to protect them more?

Graihagh Jackson travels to wetlands near her home in East Anglia while Qasa Alom reports from the Bay of Bengal. And The Climate Question catches up with an old friend of the show, Dr Musonda Mumba, Secretary-General of the Convention on Wetlands.

Twenty years ago, Hurricane Katrina devastated America’s Gulf coast and overwhelmed the city of New Orleans. The destruction and the response to the storm became infamous and are debated to this day.

Climate scientists warn that the warming world is likely to make typhoons, cyclones and hurricanes more intense and so even more dangerous.

Graihagh Jackson and Jordan Dunbar ask what the world has learned since the disaster in New Orl...

This week Host Graihagh Jackson grabs a chat with the BBC’s correspondents in two countries that will shape our future climate.

Brazil is about to host the giant COP climate conference in the Amazon, but the pace of reducing deforestation has just slowed and there are concerns about potentially weaker environmental standards. Ione Wells in Sao Paulo also talks Graihagh through proposals for oil exploration in the mouth of the rainf...

Climate change is melting thousands of glaciers in the Himalayas and having a devastating impact on the people who live there. In 2024, the BBC's Caroline Davies visited the Pakistani side of the world's highest mountain range: she told Graihagh Jackson how villagers are coping, and how they are determined to stay put despite the risks of floods and the disruption to their traditional way of life.

You can watch Caroline's reporting ...

Bill Gates, the tech billionaire turned philanthropist, has been combating poverty, disease, and inequity around the world for decades. However, in recent years he has shifted focus and resources towards the climate crisis.

Gates believes fighting climate change and fighting poverty are two sides of the same coin. Food, health and economic crises will last longer and become more severe as climate threats escalate, disproportionately...

From coral reefs and mangroves to raising the land itself, how small island nations are using natural and innovative techniques to adapt to rising sea levels and extreme weather events linked to climate change.

Jordan Dunbar chats to Tina Stege, climate envoy for the Republic of the Marshall Islands, and Dr. Rosanne Martyr, senior scientist on coastal vulnerability and adaptation, Climate Analytics.

Plus, Anna Holligan, the BBC's ...

Rare earths have been described as the oil of the 21st century, incredibly valuable both economically and in the fight against climate change. There's a battle underway around the world to mine and control these minerals - a battle that is currently being won by China.

As demand rises, the problems with rare earths are also becoming clearer because getting them out of the ground requires strip mining and the use of poisonous chemic...
