By the way, because it takes a tremendous amount of heat to melt ice, melting of arctic ice provides a natural thermostat for the planet, so temperature increase is not as high as it would be without ice. But it is one-time deal; after ice is melted, the stabilizing effect is gone, so with every year there is less of temperature-stabilizing capacity. One has to understand that “temperature” and “heat” are different things, although related - so a mixture of ice and water will absorb heat WITHOUT temperature change, until all ice is gone, because it takes heat to destroy a cristal structure of ice. If someone could just make a soundbite out of this…
