cold spell proof for global warming

today I read an article where scientists say that the current cold spell is a sign of global warming because of the deglaciation of the North Pole. Then I remembered from a physics book that to melt ice you need energy, i.e. you need heat. So where could the polar cap get the energy from - besides the Sun - to melt its ice? From the ocean! Thus it is logical that if the ice melts the ocean water gets colder and if that happens the air could get colder as well as it touches the ocean. I know weather is a rather complicated thing and many things influence it. But the deglaciation could indeed be responsible for the current cold spell and the supposedly contradiction global warming - cold weather would actually make sense. What do you think?

Yeah, the irony of things. We get colder weather due to the warming of the Earth. Weather is indeed a bit more complex to explain. Yet this thing about the polar ice cap beginning to melt causing cold spells really has some logic to it. And it's scary since the cold weather is a temporary thing. Then there will be continuous warmth that would eventually scorch everything.

right, once the ice has gone the oceans will warm up again and possibly get warmer than before amplifying the greenhouse effect. But who knows, perhaps there's some weather phenomena that can prevent that or maybe the Sun activity will reach a minimum so that the greenhouse effect outweighs the next ice age... wishful thinking I suppose
