Year 2013 Ties with 2003 as 4th Warmest Year (NOAA)
NOAA has released its Global Analysis for 2013 temperature and precipitation events. Highlights include:
- The year 2013 ties with 2003 as the fourth warmest year globally since records began in 1880. The annual global combined land and ocean surface temperature was 0.62°C (1.12°F) above the 20th century average of 13.9°C (57.0°F). This marks the 37th consecutive year (since 1976) that the yearly global temperature was above average. Currently, the warmest year on record is 2010, which was 0.66°C (1.19°F) above average. Including 2013, 9 of the 10 warmest years in the 134-year period of record have occurred in the 21st century. Only one year during the 20th century—1998—was warmer than 2013.
- Separately, the 2013 global average land surface temperature was 0.99°C (1.78°F) above the 20th century average of 8.5°C (47.3°F), the fourth highest annual value on record.
- The 2013 global average ocean temperature was 0.48°C (0.86°F) above the 20th century average of 16.1°C (60.9°F) and tied with 2006 as the eighth highest annual temperature on record and the highest since 2010, the last time El Niño conditions were present in the central and eastern equatorial Pacific Ocean. ENSO-neutral conditions were present in this region during all of 2013.
- Precipitation measured at land-based stations around the globe was near average on balance for 2013, at just 0.31 mm above the long-term average. However, as is typical, precipitation varied greatly from region to region. This is the second consecutive year with near-average global precipitation at land-based stations.
