Arctic and Antarctic sea ice coverage remain at record, near-record lows
Despite the cooling influence of La Nina this winter, the global temperature ranked among the five warmest on record in January. Earth’s polar regions continued to experience record-low ice conditions.
Let’s dive deeper into NOAA’s monthly analysis to see how the planet fared in the first month of the year:
Climate by the numbers
January 2018
The average global temperature in January 2018 was 1.28 degrees F above the 20th-century average of 53.6 degrees, according to scientists from NOAA’s National Centers for Environmental Information. This average temperature was the fifth highest for the month of January in the NOAA’s record, which dates back to 1880. This was the 42nd consecutive January (since 1977) and the 397th consecutive month (since January 1985) with temperatures above the 20th-century average. The last four years (2015-2018) saw the five warmest Januarys on record.

Other notable climate facts from around the world last month included:
Near-record-low sea ice at the poles
The average Arctic sea ice coverage in January was 9.4 percent below the 1981-2010 average, the smallest for the month since records began in 1979.
Antarctic sea ice extent in January was 17.4 percent below average, the second smallest January on record.
Warmer-than-average lands and oceans
The globally averaged land-surface temperature was 2 degrees F above the 20th-century average, ranking as the eighth warmest for the month of January.
The globally averaged sea-surface temperature was 1.01 degrees F above average and tied with 1998 as the fifth warmest for January on record.
Oceania and Europe led the continental warmth rankings
Oceania has its warmest January on record; Europe, its second; South America, its 14th; Africa, its 21st; North America, its 24th; and Asia, its 26th (tied with 1997).
