Last year was Earth’s 4th-warmest year on record, coming in behind 2016, the planet’s warmest recorded year, as well as 2015 and 2017, according to information released Wednesday by NOAA, NASA and the U.K. Met Office.

Why it matters: The yearly rankings don’t tell the whole story of long-term climate change, since natural variability can still push or pull an individual year up or down the rankings. However, the overall picture is growing starker with each passing year. Nine of the 10 warmest years on record since reliable data began in 1880 have occurred since 2005. At the same time, greenhouse gases from the burning of fossil fuels — as well as deforestation and intensive agriculture — have skyrocketed to levels not seen in more than 800,000 years.

By the numbers: For 2018, the average temperature across global land and ocean surfaces was 1.42°F (0.79°C) above the 20th century average, according to NOAA.

According to NASA’s Goddard Institute for Space Studies, global temperatures in 2018 were 1.5°F (0.83°C) warmer than the 1951 to 1980 mean.Analyses from the U.K. Met Office and the World Meteorological Organization also ranked 2018 among the top four warmest years on record.
