Animated: 140 Years of Global Surface Temperatures
For hundreds of years, Earth’s average surface temperature has been steadily increasing. And over the last decade, this global heating appears to have intensified.
Since 1880, the global average temperature has risen by an average of 0.08°C (0.14°F) every 10 years, according to the National Oceanic and Atmospheric Administration (NOAA).
But since 1981, warming has been occurring at more than twice that rate, by about 0.18°C (0.32°F) per decade.
This graphic by Pablo Alvarez shows 140 years of global surface temperatures, highlighting the 10 coldest and warmest years from 1880-2021 using data from NOAA.
Global Surface Temperatures Over Time
Over the last century and a half, there have been fluctuations in global surface temperatures, with some of the coolest years on record occurring in the late 19th century and early 20th century.
However, the last two decades have seen unprecedented warming, with the 10 warmest years on record all occurring within the last 20 years. Here’s a look at the 10 hottest years since 1800, and how they compared to the 20th century average:
