Regions with a polar climate are characterized by a lack of warm summers (specifically, no month having an average temperature of 10 °C (50 °F) or higher). Regions with polar climate cover over 20% of the Earth. The sun shines 24 hours in the summer, and barely ever shines at all in the winter (see midnight sun and polar night). Polar climate results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice.

“In time your relatives will come to accept the idea that a career is as important to you as your family. Of course, in time the polar ice cap will melt.”

“Certainly parents play a crucial role in the lives of individuals who are intellectually gifted or creatively talented. But this role is not one of active instruction, of teaching children skills,... rather, it is support and encouragement parents give children and the intellectual climate that they create in the home which seem to be the critical factors.”
—David Elkind (20th century)
