In a time of climate anxiety, 2019 was the second-warmest year since scientists began taking temperatures in 1880, government scientists announced Wednesday.
The near-record temperatures cemented the past decades title as the warmest in modern human history, according to data from NASA and the National Oceanic and Atmospheric Administration. The steady increase in land and ocean temperatures around the world has been fueled almost entirely by greenhouse gas emissions since the onset of the Industrial Revolution.
The decade that just ended is clearly the warmest decade on record, said Gavin Schmidt, director of NASAs Goddard Institute for Space Studies in New York. Every decade since the 1960s clearly has been warmer than the one before.
