2018 has officially been named the fourth hottest year on Earth, according to a new report by NASA and the National Oceanic and Atmospheric Administration.

Global temperatures rose 1.5 degrees Fahrenheit (0.83 degrees Celsius) than the mean of warming from 1951 to 1980. The data confirms a continued stretch of warming since record-keeping began in 1880.

In fact, the past five years have been, “collectively, the warmest years in the modern record,” according to NASA. 2016 currently ranks as the hottest year on record, with 2017 coming in second and 2015 third.

Overall, global temperatures have risen about 2 degrees Fahrenheit (1 degree Celsius) in the last 138 years. The report stated that much of the warming can be attributed to an increase in carbon emissions from human activity.

“The impacts of long-term global warming are already being felt — in coastal flooding, heat waves, intense precipitation and ecosystem change,” Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, said in a statement. “2018 is yet again an extremely warm year on top of a long-term global warming trend.”

Berkley Earth and Europe’s Copernicus Climate Change Service both also reported, in January, that 2018 was the fourth warmest on record. The release of the NASA/NOAA report was delayed by the US government shutdown.

NASA adds that temperatures do vary by region. Due to the continued loss of sea ice, the Arctic has experienced the strongest warming. But in the contiguous 48 states, 2018 marked the 14th warmest on record.

“The long-term temperature trend is far more important than the ranking of individual years, and that trend is an upward one,“ Petteri Taalas, secretary general of the World Meteorological Organization, told The Guardian.

“The 20 warmest years on record have been in the past 22 years. The degree of warming during the past four years has been exceptional, both on land and in the ocean.”
