  • Globally, 2019 temperatures were second only to those of 2016 and continued the planet’s long-term warming trend: the past five years have been the warmest of the last 140 years.
  • Using climate models and statistical analysis of global temperature data, scientists have concluded that this increase mostly has been driven by increased emissions into the atmosphere of carbon dioxide and other greenhouse gases produced by human activities.
  • NASA’s temperature analyses incorporate surface temperature measurements from more than 20,000 weather stations, ship- and buoy-based observations of sea surface temperatures, and temperature measurements from Antarctic research stations.
