2014 Confirmed as Hottest Year on Record
2014 ranks as Earth’s warmest since record keeping began in 1880, according to independent analyses by scientists at NASA and the National Oceanic and Atmospheric Administration (NOAA).
The analyses, released today, take into account surface temperatures over both land and sea. They further confirm the findings of the Japan Meteorological Agency, which announced 2014 as the warmest year on record on January 6. NASA, NOAA, and the Japan Meteorological Agency constitute three of the four major government agencies that track global temperature trends; the fourth, the United Kingdom’s Met Office Hadley Centre, has yet to report.
“This is the latest in a series of warm years, in a series of warm decades. While the ranking of individual years can be affected by chaotic weather patterns, the long-term trends are attributable to drivers of
Although the 2014 temperatures carry on Earth’s long-term warming trend, scientists still expect to see year-to-year variability in average global temperatures as a result of phenomena such as El Niño and
NOAA’s National Climatic Data Center (NCDC) released the 2014 temperature finding as part of their State of the Climate global analysis, which considers a wide range of climatic variables. Some other key findings from the State of the Climate:
- 2014 was the 38th year in a row that the yearly global temperature was above the long-term average.
- 2014 was also a record-warm year for global oceans.
- Including 2014, 9 of the 10 warmest years in the 135-year period of record have occurred in the 21st century.
