Live from Abu Dhabi Connect the World takes you on a journey across continents, investigating the stories that are changing our world.
An expedition team has set off on a long journey to cross Antarctica in winter. They will be traveling for several months in temperatures as low as minus 90 degrees Celsius. If that wasn't challenging enough – it's also going to be completely dark. Expedition co-leader Sir Ranulph Fiennes was forced to pull out of preparations at the end of February after he got frostbite. He's already lost several fingers during previous treks as an explorer.
Max Foster spoke to the British adventurer about the moment he realised he had to get help quickly or risk losing more fingers.
NOTE: We must warn you - you will see one picture of his frostbitten hand which some may find distressing.
