Although the polar regions radiate away more heat energy than they receive by insolation in the course of a year, they are prevented from becoming progressively colder each year by the:

Conduction of heat through the interior of the earth
Release of latent heat to the atmosphere when polar ice melts
Concentration of earth's magnetic field lines at the poles
The insulating properties of snow
Circulation of heat by the atmosphere and oceans

Suppose yesterday morning you noticed ice crystals (frost) on the grass, yet the minimum temperature reported in the newspaper was only 35o F. The most likely reason for this apparent discrepancy is that:

The thermometer was read before the minimum temperature was reached for that day
The thermometer was read incorrectly
The thermometer was in error
The newspaper reported the wrong temperature
Temperature readings are taken in instrument shelters more than 5 feet above the ground
