Summary
What effect does air travel have on the climate? That is the question listener Neil sent CrowdScience from New Zealand. If you have ever looked up at the sky and seen the wispy white streaks that airplanes leave behind, then you are looking at one of the major environmental impacts of air transport – contrails.
To find out more, Anand Jagatia goes on a journey through the rugged, lava-ridden Icelandic landscape with earth scientist Thor and discovers how both natural events like volcanic eruptions as well as man-made acts of terror can shed light on the environmental impact of aircraft. Plus, we meet a man who tailgates 737 airliners to measure their emissions.
