Throughout December 2010 and early January 2011, Nunavut, northern Quebec and western Greenland set many high temperature records. In Coral Harbour, a high of 3.3 °C (37.9 °F) in mid-December broke the old record of 1.7 °C (35.1 °F) set in 1963. The daily minimum temperature on January 6, 2011, was about 30 °C (54 °F) warmer than normal. The unusual warmth was due largely to an unseasonal area of high pressure over Greenland, and very negative values of the Arctic oscillation and North Atlantic oscillation. Mostly in the 21st century, the conditions have combined to produce an Arctic dipole anomaly that brings warm air to the Arctic regions and cold air to the continents.

Famous quotes containing the word climate:
“Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.”
—Walter Lippmann (1889–1974)
“Ghosts, we hope, may be always with us—that is, never too far out of the reach of fancy. On the whole, it would seem they adapt themselves well, perhaps better than we do, to changing world conditions—they enlarge their domain, shift their hold on our nerves, and, dispossessed of one habitat, set up house in another. The universal battiness of our century looks like providing them with a propitious climate ...”
—Elizabeth Bowen (1899–1973)
“Then climate is a great impediment to idle persons; we often resolve to give up the care of the weather, but still we regard the clouds and the rain.”
—Ralph Waldo Emerson (1803–1882)
