The map shows where average surface temperatures were up to 7 degrees Celsius above (red), below (blue), or near (white) the long-term average (1971-2000) for the first half of 2010. The warming influence of an El Niño event in the tropical Pacific contributed to one of the two warmest January-June periods on record. The contrast between warmth in Canada and cool conditions across the North Atlantic is the influence of a strongly negative phase of the Arctic Oscillation.
