NASA Confirms 2017 Among the Warmest Years on Record

NASA / National Aeronautics and Space Administration, January 18, 2018. “Earth’s surface temperatures in 2017 were the second warmest since  1880, when global estimates first became feasible”, NASA scientists found.

“This continues a decades-long trend of global warming. As the global climate continues to warm, polar ice melts, sea levels rise, and fire seasons burn hotter and longer”.
Global temperatures in 2017 were second only to 2016, which still holds the record for the hottest year. However, 2017 was the warmest year without an El Niño.

In a separate, independent analysis, NOAA (The National Oceanic and Atmospheric Administration) scientists found that 2017 was the third-warmest year in their record. The minor difference is due to different methods to analyze global temperatures used by the two agencies, although over the long-term the records remain in strong agreement.

“Despite colder than average temperatures in any one part of the world, temperatures over the planet as a whole continue the rapid warming trend we’ve seen over the last 40 years,” said GISS (Goddard Institute for Space Studies) Director Gavin Schmidt.

NASA and NOAA are two keepers of the world’s temperature data and independently produce a record of Earth’s surface temperatures, as well as changes based on historical observations over oceans and land.
