A wide range of temperature data indicate that the earth continues to get warmer. September 2012 was tied for the warmest September since the dawn of temperature records. These were the findings of the State of the Climate Global Analysis, September 2012 from the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center.
Global Averages
The average combined global land and ocean surface temperature for September 2012 tied with 2005 as the warmest September on record, at 0.67°C (1.21°F) above the 20th century average of 15.0°C (59.0°F). Records began in 1880. The globally-averaged land surface temperature for September 2012 was the third warmest September on record, at 1.02°C (1.84°F) above average. The globally-averaged ocean surface temperature tied with 1997 as the second warmest September on record, at 0.54°C (0.97°F) above average.
The average combined global land and ocean surface temperature for January–September 2012 was the eighth warmest such period on record, at 0.57°C (1.03°F) above the 20th century average.
Hungary
Following the second warmest summer (June–August) for Hungary since national records began in 1900, monthly temperatures remained above average across the entire country during September, ranging from about 1.0°–3.5°C (1.8°–6.3°F) above the 1971–2000 average, according to the country’s national meteorological service, Országos Meteorológiai Szolgálat.
Australia
Australia experienced its third warmest September since records began in 1950, with the nationally-averaged maximum temperature 1.94°C (3.49°F) above the 1961–1990 average. The minimum temperature was also above average but not quite as extreme as the maximum, at 0.42°C (0.76°F) above the long-term average.
Argentina
According to Argentina’s national meterological service, Servicio Meteorológico Nacional, the monthly-averaged daily, maximum, and minimum temperatures were all above normal across Argentina, particularly in the central and northern regions of the country. Record high September minimum temperatures were observed across parts of the midwest.
Japan
As indicated in the land and ocean temperature percentiles map above, Japan observed record warmth during September. According to the Japan Meteorological Agency, the greatest warmth was observed across northern Japan (regions of Hokkaido and Tohuko), which was 3.7°C (6.7°F) above average. It was below average across Okinawa, which had been impacted by Super Typhoons Sanba (middle of the month) and Jelawat (end of the month).
