In the summer of 2003, Europe experienced its most intense heatwave on record - one that saw more than 70,000 people lose their lives. Experiencing the effects whilst on holiday in Tuscany, climate scientist Peter Stott was struck by the idea that just maybe, he could use a modelling system developed by his team at the UK’s Met Office Hadley Centre, to study extreme weather events such as this very heatwave mathematically; and figure out the extent to which human influences were increasing their probability. That’s exactly what he went on to do - and, through this work and more, Peter has helped to shine a light on the causes and effects of climate change. His career, predominantly at the Met Office Hadley Centre, has seen him take on climate change sceptics and explain the intricacies of greenhouse gas emissions to global leaders. His work with the Intergovernmental Panel on Climate Change even earned him a share of the 2007 Nobel Peace Prize. But the biggest challenge remains: Peter talks to Jim Al-Khalili about whether humanity can adapt quickly enough to deal with the increasingly dangerous effects of our warming world...
