Exclusive: Military reservists and veterans set off on Antarctic climate change expedition

A group of military reservists and veterans has set off on a five-week trek across Antarctica to carry out climate change research.

The eight-strong team is heading to an area of the continent that has never been explored.

Along the way, the team will collect a mass of scientific data to help researchers understand the impact climate change is having on Antarctica.

The team will also mark the life of legendary Antarctic explorer Sir Ernest Shackleton, stopping near the Weddell Sea to mark the 100th anniversary of his last expedition.
