Pump and freeze
Of all the news on television today the most outstandingly troubling piece of news is that our Arctic will not have ice in the summers real soon. Might we pump water to the surface during the winter months to build rebuild the ice packs. Not unlike a refrigerator the winter temperatures will freeze the water pumped to the surface. We can't just set back and measure the ice melting. We must take responsibility to ensure it's future. No costs are to high for our future.

Inappropriate?Hi Roland
Thanks for thinking about and sharing solutions and ideas.
However, in this case, Martin Hiller from our climate change team responded with the following:
I am afraid this won't work: water at deeper levels is warmer than water at the surface - check out the key word water anomaly, the fact that water is at its highest density (and therefore heaviest) when +4°C warm. That is why water freezes from the top not from the bottom. Also, quite frankly, the energy used to pump such quantities of water around as you seem to indicate would create more damage than good through massively increased emissions.
