Animated: Comparing Two Centuries of Global Surface Temperature

Comparing Two Centuries 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 …
