This past year, 2017, was among the warmest years on record, according to new data released by NASA and the National Oceanic Atmospheric Administration.
The planet's global surface temperature last year was the second highest since 1880, NASA says. NOAA calls it the third warmest year on record, because of slight variations in the ways that they analyze temperatures.
Both put 2017 behind 2016's record temperatures. And "both analyses show that the five warmest years on record have all taken place since 2010," NASA said in a press release.
