Arctic ice is melting rapidly and irreversibly, but we can do something about it
Global warming has reduced the Arctic sea ice volume already by 75% over the last 40 years, and even in the most optimistic carbon emissions reduction scenarios, the Arctic sea is expected to experience ice-free summers as early as the thirties.
This will further accelerate the climate crisis and start a series of devastating feedbacks, since the Arctic sea ice functions as the earth’s refrigerator by reflecting the sun’s heat back into space.
We aim to restore the Arctic ice as heat shield by thickening the ice in winter through pumping sea water on top of it in strategically chosen locations across the Arctic Sea.

Ensuring effectiveness in extreme environments
Thickening large areas of ice by pumping seawater onto it, in extreme cold conditions, presents several challenges. One of the hurdles we’ve encountered is ensuring even spread the water. To tackle this, we’ve been testing hoses to optimise the distribution of water...
Our mission and approach in less than three minutes.
While restoring Arctic ice cannot replace the urgently needed reduction of carbon emissions, it is a crucial measure to avert the devastating feedback loops that come with Arctic sea ice loss.
