Global temperatures in 2015 have set a new record for the hottest year since 1880, according to NASA’s report.
They shattered the previous record set in 2014 by 0.13°C degrees, the institution stated.
The planet’s average surface temperature has risen around 1°C since the late 19th century, it added.
That’s due to a change largely driven by an increase on carbon dioxide and other human-made emissions into the atmosphere.
Phenomena such as El Niño or La Niña, which warm or cool the tropical Pacific Ocean, could contribute to short term variations in the global average temperature, according to NASA.
In fact, a warming El Niño affected the planet during most of 2015, it stated.
NASA Administrator Charles Bolden said: “Climate change is the challenge of our generation, and NASA’s vital work on this important issue affects every person on Earth. Today’s announcement not only underscores how critical NASA’s Earth observation program is, it is a key data point that should make policy makers stand up and take notice – now is the time to act on climate.”
