Last June, as we launched our campaign to save the Arctic, we made a promise. We promised that if a million joined our movement, we would take their names to the North Pole and plant them on the seabed 4km beneath the ice as statement of our joint commitment to Arctic protection.

Well you smashed that target in less than a month. And in the nine months that have passed since, our movement has tripled.

In a few short days, a group of brave adventurers will set off on a gruelling trek across the Arctic Ocean to fulfil this promise as part of a global movement now almost three million strong.

Meet the incredible team and learn all about their mission in this video – made with Oscar-nominated LA production company, Arctic defenders and all round heroes Dirty Robber
