2015 is the Warmest Year on Record

Have You Heard?

  • 15 of the 16 warmest years on record globally have occurred since 2001.
  • The globally-averaged temperatures from 2014 to 2015 increased by 0.23 degrees Fahrenheit, the greatest year-to-year temperature increase on record.
  • Earth’s average temperature has risen about 1.62 degrees Fahrenheit above the 20th century average.

The global average annual temperature in 2015 was the warmest on record. This is the 15th time since 2001 that a year has concluded as the warmest on record, continuing a long-term warming trend that has been tracked and predicted by NASA and NOAA scientists.

While 2015 was the warmest on record globally, there were regional variations in average annual temperature. For example, NASA and NOAA reported that the 2015 annual mean temperature for the contiguous 48 United States was the second warmest on record.

The warming effect from El Niño in the tropical Pacific Ocean had an assist in the record-breaking temperatures, but it is ultimately the cumulative effect of the long-term warming trend that has resulted in 2015 being the warmest year on record globally.
