The Climate Question

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.
