one of the key advocates of this approach is professor sir david kee, who chairs the centre for climate repair here at downing college in cambridge university. what we are planning is to imitate natural processes. so, in terms of looking at the arctic ocean, which is now 50% exposed to sunlight, for the three months of the polar summer, which is when these extreme weather events occured. how do we manage to keep the ocean covered with ice so that once again it reflects icepack? that is what we are trying to do. and the natural process we are focused on at the moment is what happens when there is a storm at sea, you create little droplets of sea water in the year. the smaller droplets are picked up by winds going up. that can create white cloud cover. what if we imitate this by creating tiny droplets of sea water in the ocean and simply pumping them over the surface of the ocean? we plan to encircle the arctic circle with these remotely driven ocean vessels which have been designed in great detail, so that when we get a met office information that the wind is blowing towards the arctic s
