2018 fourth warmest year on record: NASA, NOAA

The NASA and NOAA reports are consistent with analyses by other governments, including the Japan Meteorological Agency and the European Union's Copernicus Climate Change Service, both of which also concluded that 2018 was the fourth-warmest year on record.

The year 2016, which was 1.69 degrees Fahrenheit warmer than the 20th-century average, holds the top spot, with 2018 at 1.42 degrees F warmer.

Earth's higher-than-average global surface temperatures in 2018 resulted in the year being named the fourth warmest on record, according to independent analyses released by two USA agencies Wednesday.

Overall, global temperatures have risen about 2 degrees Fahrenheit (1 degree Celsius) in the last 138 years.

While this planet has seen hotter days in prehistoric times, and colder ones in the modern era, what sets recent warming apart in the sweep of geologic time is the relatively sudden rise in temperatures and its clear correlation with increasing levels of greenhouse gases like carbon dioxide and methane produced by human activity.

"The impacts of long-term global warming are already being felt a" in coastal flooding, heat waves, intense precipitation and ecosystem change", said Schmidt.


NASA's global temperature analyses use surface temperature recordings from 6,300 weather stations around the world, incorporating ship- and buoy-based measurements of ocean surface temperatures as well as measurements of surface temperatures from Antarctic research outposts. The following year, 2017, is ranked as the second warmest. "That means kids graduating from high school have only known a world of record-breaking temperatures". It also said that the 20 warmest years in history all occurred within the last 22 years. It's part of a continued global warming trend.

The U.S. temperature in 2018 was the 14th warmest on average, said NOAA climate monitoring chief Deke Arndt.

The Earth experienced its fourth-hottest year in more than 136 years in 2018.

WMO also released a report on Wednesday that the globally averaged temperature in 2018 was about 0.38 degrees Celsius above the 1981 to 2010 long-term average.

Despite worldwide efforts, planet-warming emissions are trending upward. "These included the awful wildfires in California and the devastating hurricanes Florence and Michael, all of which bear the fingerprints of climate change".
