    Five-Year Global Temperature Anomalies from 1880 to 2014

    Jan. 16th, 2015
    (updated Aug. 25th, 2023)

    This color-coded map in Robinson projection displays a progression of changing global surface temperature anomalies from 1880 through 2014. Higher than normal temperatures are shown in red and lower then normal termperatures are shown in blue. The final frame represents the global temperatures 5-year averaged from 2010 through 2014. || NASA Finds 2014 Was Warmest Year in Modern RecordThe year 2014 ranks as Earth’s warmest since 1880, according to an analysis by NASA scientists.The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000. This trend continues a long-term warming of the planet, according to an analysis of surface temperature measurements by scientists at NASA’s Goddard Institute of Space Studies (GISS) in New York.In an independent analysis of the raw data, NOAA scientists also found 2014 to be the warmest on record.For understanding climate change, the long-term trend of rising temperatures across the planet is more important than any year’s individual ranking. These rankings can be sensitive to analysis methods and sampling. While 2014 ranks as the warmest year in NASA’s global temperature record, it is statistically close to the values from 2010 and 2005, the next warmest years.Since 1880, the average surface temperature of Earth has warmed by about 1.4 degrees Fahrenheit (0.8 degrees Celsius), a trend that is largely driven by the increase in carbon dioxide and other human emissions into the planet’s atmosphere. The majority of that warming has occurred in the past three decades.Regional differences in temperature in any year are more strongly affected by weather dynamics than the global mean. For example, in the U.S. in 2014, parts of the Midwest and East Coast were anomalously cool, while Alaska and three western U.S. states – California, Arizona and Nevada – recorded their warmest years on record, according to NOAA, which assesses official U.S. temperature records.The GISTEMP analysis website is located at: http://data.giss.nasa.gov/gistemp/ ||

    2014 Global Temperature Anomalies: United States to Global view

    Jan. 16th, 2015
    (updated May 3rd, 2023)

    This visualization of annual global temperature anomalies from 2014 starts with a local view of the United States and then zooms out to the global color-coded map. Blue represents colder then normal temperatures and red represents warmer then normal temperatures. || The year 2014 ranks as Earth’s warmest since 1880, according to an analysis by NASA scientists.
