Indicator: Global Surface Temperatures
Key Points: Since the 1880s, the average global temperature has increased by 1.8°F. Since the 1980s, average temperatures have exceeded the last century's average every year. About the Indicator: Global average temperatures include air temperatures measured on land and sea surface temperatures measured from ships and buoys worldwide. The data shown in the graph were drawn from the National Oceanic and Atmospheric Administration (NOAA) Global Historical Climatology Network (GHCN) and International Comprehensive Ocean-Atmosphere Data Set (ICOADS). Why It's Important: Changes in global temperatures over the past century provide one important line of evidence for the effects of increasing greenhouse gas emissions. Such evidence can inform national and international policy discussions.
