9. Why does it become colder in some regions despite global warming?
Because of global warming, warm air masses are moving further north and significantly warm the Arctic. Simultaneously, cold air masses are repressed which move southward. In addition, the increasing melt water can repress warm sea currents into the South. It becomes less cold in the polar regions and warmer in the southern regions. This is comparable with an open refrigerator from which the cold air escapes. If this- cold air disappeared, the climate will also warm in those affected regions. These cold waves form the disappearing cold from the Arctic.
