It it felt like this past year was hotter than usual, you were not imagining things. According to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA), Planet Earth’s surface temperatures during 2016 were the warmest since modern recordkeeping began in 1880. This finding makes 2016 the third year in a row to set a new record for global average surface temperatures and continues what has been a long-term warming trend. Globally-averaged temperatures in 2016 were 1.78°F warmer than the mid-20th century mean.
