Both could be connected so that the cold winds that belong in the Arctic have broken out southwards to chill us while warm winds melt the ice cap. Warm air goes north; cold air comes south. At the moment, this seems to be mainly affecting the Arctic sea ice, which is shrinking at an astonishing rate but does not of itself contribute to rising sea levels. Sea levels will rise for the rest of this century even if the ambitious targets of the Paris accords are met. Even if that happens, the latest research suggests that sea levels will continue to rise for another two centuries, and may do so by a completely catastrophic amount.
