Air temps 9 degrees above normal For example, autumn air temperatures in the Arctic are at a record 9 degrees Fahrenheit above normal. Rising temperatures help melt the ice, which in turn allows more solar heating of the ocean. In addition to global warming there are natural cycles of warming and cooling, and a warm cycle in the 1990s added to the temperature rise.
