Our changing climate affects all genders - with extreme weather events, heat, drought and flooding putting pressure on the lives and wellbeing of entire communities.
Yet the United Nations says that women and girls bear a disproportionate share of the burden and that by 2050, climate change may push up to 158 million more women and girls into poverty,16 million more than the total number of men and boys.
So why exactly are women and girls more affected by climate change? And how can we build a better future?
In this episode, Hosts Graihagh Jackson and Esme Stallard talk to Mary Robinson, former Chair of The Elders, former President of Ireland and former UN High Commissioner for Human Rights and Envoy on Climate Change.

The system of ocean currents known as the Atlantic Meridional Overturning Circulation or AMOC plays a crucial role in the global climate, helping to keep Europe relatively mild and to circulate vital nutrients for marine life.
But scientists are worried that the AMOC system might be starting to weaken because of climate change and that, in the worst case scenario, it might eventually collapse.
This could lead to freezing temperatures in Europe and changing rainfall patterns around the world. The Amazon rainforest could dry out, for example, and the monsoon in South East Asia might also be affected.
But there's a lot of uncertainty about the AMOC in climate models, as well as a lack of real world data because scientists have only been measuring this vital ocean system for a couple of decades.
In this show, The Climate Question hosts Graihagh Jackson and Esme Stallard talk to Professor Penny Holliday. Penny is the Chief Scientific Officer at the UK's National Oceanography Centre. She has been leading research on the strength and variability of AMOC for decades.

When a powerful El Niño strikes, it can devastate harvests, flood communities and kill thousands of people. Scientists have been warning for months that this one could become the strongest on record. The question is: are we ready?
In this episode of The Climate Question, hosts Graihagh Jackson and Jordan Dunbar find out how communities in Kenya and Peru are preparing for a potentially historic El Niño.
They speak to BBC Nairobi Correspondent Thomas Mukhwana and Miguel Aristegui from the international development charity Practical Action about the challenges that lie ahead. Miguel's charity worked with the Peruvian government on an action plan it introduced after a localised El Niño event in 2017.
From flood-prone neighbourhoods in Nairobi to Peru's newly installed meteorological radar network, we explore what happens when weather extremes collide with existing vulnerabilities. Can early warning systems, emergency planning and climate adaptation reduce the risks? Or will many communities remain exposed when the worst impacts arrive?

From Mongolia to Texas, record numbers of lithium-ion batteries are being added to the world's electricity grids - helping to provide more reliable power and speeding up the transition to renewable energy sources such as wind and solar.
China is installing over half of these new batteries, often in giant battery farms, followed by the United States and Europe. And with prices dropping fast, the trend is likely to continue and spread to more developing countries.
But is battery development moving fast enough to help us meet our climate goals? And what about alternatives to lithium-ion technology like using air, water or even sand? Could these types of batteries help us with other energy problems such as storing heat over the winter.
In this edition of The Climate Question, Hosts Graihagh Jackson talks to Akshat Rathi, senior climate reporter at Bloomberg News and host of Bloomberg Green's Zero podcast.

The United Nations says the world will pass its most important climate target within a few years. So can we bring the planet's temperature back down quickly? Or will the damage be irreversible?
In 2015, world leaders agreed in Paris to try to keep the global temperature below 1.5 degrees above pre-industrial levels to avoid the worst effects of climate change.
But the UN now says what scientists call "overshoot" is guaranteed, and it may have devastating consequences.
Experts are worried that the higher temperature may trigger "tipping points" in vital parts of our planet's climate system, including coral reefs, glaciers, rainforests and ocean currents.
Once past their tipping points, they could flip from helping to keep the Earth cool to making it even warmer.
In this show, The Climate Question hosts Graihagh Jackson and Jordan Dunbar talk to Johan Rockström, Director of the Potsdam Institute for Climate Impact Research

The Philippines and Pakistan are now the world's top solar panel importers. We find out why, and what other countries can learn from the boom!
Cheap solar panels, mainly imported from China, are transforming lives and slashing electricity bills across Asia.
In the last year, Filipinos have put up five times as many rooftop solar panels as the previous ten years combined. Installation companies are struggling to keep up with demand.
In Pakistan, where the boom started earlier, solar power has reached every sector of the economy from the textile industry to farming. Solar has helped Pakistanis weather the current energy crisis and reduced the country's reliance on imported fossil fuels.
The Climate Question Host Jordan Dunbar talks to Filipino climate journalist, Jhesset Enano, and Pakistani energy analyst, Zeeshan Ashfaq, from the Renewables First think tank in Islamabad.

Huge construction projects are transforming China - think enormous dams, giant solar power farms and a vast high-speed rail network. Will Beijing's "engineering mindset" help it deal with climate change?
China's senior leadership is dominated by engineers, starting with President Xi, who trained as a chemical engineer in the 1970s. They have overseen megaprojects like the 50-kilometre bridge joining Hong Kong and Macau, and a plan to move water from southern China to the much drier north.
The engineering mania extends to energy, where the world's largest polluter has invested trillions of dollars in wind and nuclear power, as well as high voltage transmission lines spanning the country.
But China still uses a huge amount of coal power, and its mega projects have often damaged the local environment and led to the displacement of millions.
So what does Beijing's approach mean for climate change? And can China build its way out of the problem?
In this edition of The Climate Question Host Jordan Dunbar and BBC Presenter Celia Hatton talk to Dan Wang, the author of Breakneck: China's Quest to Engineer the Future. Dan is currently a research fellow at Stanford University's Hoover Institution.

African forests are vital for food and economic development, as well as for supporting millions of species of animals and plants. We find out how to protect them better with one of Africa’s top environmentalists!
From the giant Congo rainforest to the Kenyan highlands and the mangroves of Mozambique, Africa’s forests are some of the most spectacular places on Earth. And these sensitive ecosystems are not just important for Africa: they play a vital role in the global climate because they store huge amounts of carbon dioxide and pump out oxygen.
Kenyan environmentalist Wanjira Mathai has been campaigning to protect and nurture forests for decades. She tells The Climate Question about the challenges they now face across Africa from rapid urbanisation, mining and logging. The solution, according to Wanjira, is to place a proper economic value on the environmental services provided by forests and the communities who live in them – whether that’s supplying water and food, or helping to prevent floods sweeping through cities such as Nairobi. Wanjira Mathai is Managing Director, Africa and Global Partnerships at the World Resources Institute. She’s been chatting to The Climate Question host Jordan Dunbar and BBC Senior Climate Reporter Esme Stallard.

Experts say we may now need to spend more on cooling our homes than heating them because of climate change. In fact, the International Energy Agency thinks the equivalent of 10 new air conditioners every second will be installed for the next 30 years!
This surge in air con will put strain on the world’s electricity grids, which are still mostly powered by fossil fuels. The units also pump heat into the streets outside our homes – making cities feel even hotter when we step outside.
But there are alternative options – like redesigning houses to include more shading and increase the air flow, or using fans and misting systems. We could also plant more trees or even change the colours of our homes to reflect more sunlight!
In this edition of The Climate Question, Host Graihagh Jackson talks to BBC Tokyo Correspondent, Kurumi Mori, and Radhika Khosla, Professor of Environmental Science and Policy at the University of Oxford.

Huge wildfires have been sweeping across Southern Europe and North America. Is climate change increasing the risk? And what can we do?
Weather experts say the world is starting to see new types of wildfire – including enormous Pyrocumulonimbus fire clouds that spit lightning and black hail.
These infernos can burn for more than a year. They can also spawn fire tornadoes, which move at more than 200 kilometres an hour, destroying everything in their path.
The Climate Question hosts Graihagh Jackson and Jordan Dunbar talk to John Vaillant, the author of “Fire Weather”, about how wildfires are increasing in intensity and frequency, and how they are burning in places they have never burned before.

Climate activists have blocked highways, scaled oil rigs and even thrown soup at master artworks. But have protests ever made a difference?
The modern green movement started in the 1970s when Greenpeace sailed a fishing boat towards a nuclear test site in Alaska. It now encompasses everything from bake-ins and marches to Radiohead concerts.
A small minority of activists even favour breaking the law to raise awareness about climate change. Some of them have superglued themselves to railings and blocked bridges.
BBC Climate Editor Justin Rowlatt has made a new podcast series about the green movement – and the heated splits among activists about tactics. He talks to Climate Question hosts Graihagh Jackson and Jordan Dunbar about the past - and future - of climate protest.

Scientists are warning that climate change and deforestation increase the risk of outbreaks of deadly diseases. How big is the danger? And what action can we take?
Dr Neil Vora is a so-called “disease doctor” - an epidemiologist who has travelled the world to help trace the sources of outbreaks of Ebola, cow pox and rabies.
Dr Vora tells The Climate Question hosts Graihagh Jackson and Jordan Dunbar about his specialism in zoonotic diseases, which are caused by infections passing from animals to humans. He is worried that the combination of climate change and cutting down forests will lead to more human-animal contact, and that the higher stress levels experienced by animals such as bats and monkeys will make them more likely to pass on deadly pathogens.
Dr Vora says we need to act now to protect forests and avoid the possibility of epidemics or even a pandemic.
Neil Vora started his career at the US Centres For Diseases Control and Prevention. He is now Executive Director at the Preventing Pandemics at the Source Coalition.

More than seven billion of us are expected to be living in urban areas by 2050. So what are the world’s great cities doing about climate change?
Humans are now city creatures – with more than half the world’s population already living in urban environments, and huge growth expected in cities in Asia and Sub-Saharan Africa during the rest of the 21st century.
So mayors are on the front line of dealing with climate change – whether it’s keeping people cool during heatwaves or redesigning cities to cope with floods.
In this edition of The Climate Question, Host Jordan Dunbar hears about inspiring solutions from cable cars in Colombia to water parks in the Netherlands and city gardens in the Philippines.
His guests are Yvonne Aki-Sawyerr, the mayor of Freetown in Sierra Leone and Co-Chair of the C40 Cities Coalition, and Rogier van den Berg, an architect and urban planner who’s Global Director at the WRI Ross Center for Sustainable Cities.
Jordan, Yvonne and Rogier also discuss the crucial role that cities need to play in reducing carbon emissions by making buildings more energy-efficient and rethinking transport.

Scientists say the El Niño weather pattern has started and this one is potentially so strong that it could have devastating effects in many parts of the world. So how does El Niño work exactly? And what’s the connection with climate change?
El Niño starts when water temperatures rise near the Pacific coast of South America, but the impact on weather is felt around the globe. Some regions are more likely to experience severe droughts or more powerful storms; others could face the threat of severe flooding.
This “Super” El Niño is likely to add 0.2 or 0.3 degrees to the global temperature. When added to the impact of climate change, scientists say the world could be headed for a new heat record in 2027.
In this edition of The Climate Question, hosts Graihagh Jackson and Jordan Dunbar chat to Mark Maslin, Professor of Earth System Science at University College, London, about what might happen and how the world can prepare.

Parts of India have been facing extreme heat - with temperatures soaring past 46 degrees Celsius. But a less familiar story unfolds after dark. When temperatures stay high after sunset, an essential human need is threatened: sleep.
Scientific research suggests that hot nights are leading many of us around the world to lose shut-eye already. Our bodies need to cool down to fall asleep – but hotter nights make that much harder. And the impacts go way beyond just feeling tired; disrupted sleep has links to poor cardiovascular health and depression. Women, children, the elderly and those living in hot countries with less income are most affected.
As global temperatures rise due to climate change, experts warn that the impact on our sleep – and our health – will only worsen.
Presenter Graihagh Jackson speaks to sleep expert Dr Sophie Bostock and BBC Marathi reporter, Janhavee Moole. They explore how rising temperatures are disrupting sleep in India and beyond – and share practical tips on how to stay cool in a warming world.

Scorching temperatures are expected at this year’s World Cup in the USA, Mexico, and Canada. How will players and fans cope? And how will it affect the action on the pitch?
Scientists are concerned about the impact of extreme heat on the biggest sporting event in history.
The organisers, FIFA, is introducing mandatory water breaks to keep players cool, but experts say the hot conditions may slow down the game and give an advantage to teams that play more matches in air-conditioned stadiums.
There’s also concern about the health effects on fans. FIFA has put in place measures such as cooling areas and misting systems, but some say the plans don’t go far enough.

In the global race for critical minerals - could the seabed provide solutions? Or should we leave these metal-rich environments undisturbed?
Governments and mining companies around the world are on the hunt for the critical minerals we need for the green tech transition. And there’s growing interest in an unlikely source – potato-shaped nodules that are found kilometres below the surface of our oceans.
These polymetallic nodules contain high levels of elements like cobalt, nickel, manganese and copper. Supporters of deep-sea mining say that harvesting them might be less damaging to the environment than mining on land. But many scientists support a moratorium; they say industrial activity on the seabed could damage the biodiversity of a fragile part of our planet.
The BBC’s Climate and Science Reporter Georgina Rannard has been following the deep-sea mining debate for five years. She chats to Hosts Graihagh Jackson and Jordan Dunbar.

In 1986, the Chernobyl nuclear accident devastated the Soviet Union and shocked the world. But, 40 years on, are we now seeing a nuclear renaissance? And what does that mean for the climate?
Climate Question host Jordan Dunbar has just visited the most contaminated place in the world for a BBC World Service documentary. He tells co-host Graihagh Jackson about the ghostly atmosphere in the former Chernobyl control room and the huge dome that now covers the remains of the nuclear reactor that exploded.
Jordan and Graihagh also discuss how the disaster set back the nuclear power industry for decades. Now, however, nuclear is firmly back on the international agenda because of rising power demand and concerns about energy security.

With more and more people moving to cities, informal settlements are expected to grow. When floods hit these unplanned places, it can be disastrous, as we often don’t know much about them. Crucial questions often remain difficult to answer, like how many people live there, what are the buildings made of, and could they withstand a flood?
