The year 2014 ranks as Earth’s warmest since 1880.
Earth is getting warmer, and global temperatures observed in 2014 are an example of just that. An analysis of surface temperature measurements by scientists at NASA’s Goddard Institute of Space Studies reveals 2014 was the warmest year on record. Since 1880, the start of the modern meteorological era, Earth’s average surface temperature has warmed by about 1.4 degrees Fahrenheit (0.8 degrees Celsius). The majority of that warming has occurred in the past three decades, largely driven by the increase in carbon dioxide and other human emissions into the planet’s atmosphere. With the exception of 1998, the 10 warmest years have now taken place since 2000. Watch the video to see how global temperatures have changed from 1880 through 2014.
