1. “The average combined global land and ocean surface temperature for August 2012 was 0.62°C (1.12°F) above the 20th century average of 15.6°C (60.1°F). This is the fourth warmest August since records began in 1880.
The globally-averaged land surface temperature for August 2012 was the second warmest August on record, at 0.90°C (1.62°F) above average, while the globally-averaged ocean surface temperature was the fifth warmest on record, at 0.52°C (0.94°F) above average.
The average combined global land and ocean surface temperature for June–August 2012 was 0.64°C (1.15°F) above the 20th century average of 15.6°C (60.1°F), marking the third warmest June–August on record.
The globally-averaged land surface temperature for June–August 2012 was the all-time warmest June–August on record, at 1.03°C (1.85°F) above average.
The combined global land and ocean average surface temperature for January–August 2012 was the ninth warmest such period on record, at 0.56°C (1.01°F) above the 20th century average.”
2. “The average global temperature across land and oceans during August 2012 was 0.62°C (1.12°F) above the 20th century average of 15.6°C (60.1°F) and ranked as the fourth warmest August since records began in 1880. Monthly global temperatures anomalies have been among the five highest for their respective months for five consecutive months, since April 2012. August 2012 marks the 36th consecutive August and 330th consecutive month with a global temperature above the 20th century average. The last below-average August temperature was August 1976 and the last below-average temperature for any month was February 1985. At the hemispheric scale, the Northern and Southern Hemisphere each also ranked as fourth warmest on record.”
3. “Over land, the monthly average global surface temperature for August was 0.90°C (1.62°F) above the long-term average, tying with 2001 and 2011 as the second warmest August in the 133-year period of record, behind 1998. The Southern Hemisphere land tied with 2005 as the third warmest (0.86°C / 1.55°F above average) while the Northern Hemisphere land ranked seventh warmest (0.91°C / 1.64°F above average). The greatest anomalous warmth occurred across far eastern Canada, southern Greenland, central and southern Europe, western Kazakhstan, Japan, Western Australia, and Paraguay. Parts of Siberia were notably cooler than average.”
4. “For the period June–August, the average global temperature across land and oceans was 0.64°C (1.15°F) above the 20th century average, making this the third warmest such period on record. It was the second warmest June–August in the Northern Hemisphere and ninth warmest in the Southern Hemisphere.
Considering global land surfaces only, June–August 2012 was record warm, at 1.03°C (1.85°F) above average. The highest anomalies occurred across parts of the Northern Hemisphere, including most of the contiguous United States and Canada, southern and eastern Europe, Kazakhstan, and eastern Siberia. Even with cooler-than-average temperatures in Alaska and northern Europe, the Northern Hemisphere observed its all-time warmest summer on record. And even with below-average temperatures across much of southern South America and northern and eastern Australia, the Southern Hemisphere observed its tenth warmest winter on record.”
