Artist Angela Palmer embarked on a mission two years ago to try to capture the physical properties of climate change - by finding what is thought to be the most polluted air on Earth, and the purest. Some of the discoveries Angela Palmer made on her journey - to Linfen in China, and Cape Grim in Tasmania - are on show at the Wellcome Collection in London. Take a tour with the artist herself.
