Researchers conclude the North Pole has so much ice because of a temperature difference years ago that forced more water to evaporate in the summer (hotter summer) and then more snow in the winter (colder) to produce the ice we have today.
This is one of those theories that scientists must love to work on. I mean you can sit all day, think thoughts like this, develop a theory, and then spout it. But who cares? More to the point, how can anyone test this theory? Should we warm the planet, then cool it to see if the ice first melts away, and then reappears after the cooling?
