This year, dramatic wildfires wreaked havoc across the globe from Australia to Siberia. CrowdScience listener Melissa wants to know the extent to which climate change is a factor in blazes that appear to be increasing in both frequency and intensity.

Presenter Anand Jagatia hears how scientists use alternative worlds in computer models, to understand the role that global warming plays. After Siberia’s hottest ever year on record, he discovers the impact of increasing temperatures on boreal forests – and how they could help release huge stocks of carbon that has been stored in the soil. But is there anything we can do to prevent this happening? He visits the UK’s Peak District region, where conservationists are re-wilding a massive area with a special species of moss, which may offer a solution to an increase in infernos.
