How do we stay cool in a warming world?

Heatwaves are already the most deadly of climate risks. If we
don’t keep climate change in check, we’ll experience more of
them, reaching even higher temperatures.


Already we need cooling to keep our homes, hospitals and
workplaces comfortable, our vaccines stable and our food
nutritious. As the planet warms up we’ll have even greater need.


Currently the cooling industry is incredibly polluting – it
accounts for around 10% of global CO2 emissions. And the demand
for it is only going to increase. An International Energy Agency
report said that the amount of air conditioners will grow by 5.6
billion by 2050, up from 1.6 billion today – which amounts to 10
new ACs sold every second for the next 30 years.


So how can we cool our warming world sustainably?


This episode looks at the biggest problems with cooling, the
rapid rise in air conditioners and the surprisingly simple ways
we can keep things cool without using any energy at all.
