Earth's Warming Trend Continued in 2018

  • NASA and NOAA ranked 2018 as the fourth warmest year on record.
  • The US experienced 14 billion-dollar weather disasters in 2018, which resulted in the deaths of at least 247 people and approximately $91 billion in damage.
  • Since the 1880s, the average global surface temperature has risen about 2°F.

Continuing earth's long-term warming trend, NASA has reported that globally averaged temperatures in 2018 were 1.5°F warmer than the 1951 to 1980 mean. The warmest year on record was 2016

While 2018 was the fourth warmest year on record globally, there were regional variations in average annual temperature. For example, NOAA reported that the 2018 annual average temperature for the contiguous 48 United States was the 14th warmest year on record. While some parts of the contiguous US experienced near-normal temperature much of the contiguous US was warmer than average, particularly west of the Rockies and across the coastal Southeast. 

NOAA reports that 2018's weather story was more about wetness than heat. Precipitation for the contiguous US averaged 34.69 inches above average, the third wettest year on record.
