As we all know in recent years the Artic has been suffering because of global warming. Global warming is causing the ice to melt in the Artic. The heat from global warming is caused by greenhouse gases that come out of power plants and other man made gas emitters around the world. Others think it is caused by natural occurences. In fact, the Artic has been heating up much faster then the rest of the world! Why should we care about what happens to the Artic? Well the reason is because the Artic distributes heat around the world because of ocean currents. Since the Artic is melting the water around it is becoming less salty and dense which weakens the distribution of heat. If this were to happen some areas on the Earth may get colder even though it is called Global Warming.
