   Low polar sea-ice coverage continues

  • The average Arctic sea ice coverage (extent) in May was 8.1 percent below the 1981–2010 average, the second smallest extent for May on record. The near-record low coverage stemmed from much-below-average sea ice in the Bering and Chukchi seas.

  • The Antarctic sea ice extent was 8.6 percent below average, the third smallest on record for May. Below-average ice coverage remained in parts of the Weddell Seaoffsite link.

   Warmer-than-average lands and oceans, again

  • The globally averaged land-surface temperature was seventh highest on record for May and the fifth highest for the March–May period and the year to date.

  • The globally averaged sea-surface temperature was fourth highest on record for May and the March–May period, and the fifth highest for the year to date.

   The heat was on in Europe

  • Europe had its warmest May on record; North America, its second; South America, its sixth; Africa, its ninth; Asia, its 15th; and Oceania had its 35th warmest.
