The final numbers are in: 2014 is officially the hottest year on record in the past 135 years, NASA and the National Oceanic and Atmospheric Administration (NOAA) announced Friday.

The record does not come as a surprise as it’s another marker of the sustained accumulation of heat in the atmosphere thanks to the unabated emissions of greenhouses gases such as carbon dioxide. Nine of the 10 warmest years on record have all occurred in the 21st century, with the exception of the blockbuster El Nino year of 1998. It also marks 38 straight years of above-average global annual temperatures.
