the year 2014 now ranks as the warmest on record since 1880 according to an analysis by nasa scientiststhis video shows a time series of five-year global temperature averages mapped from 1880 to 2014 as estimated by scientists at nasas goddard institute for space studies giss in new yorkwhile scientists expect temperatures to fluctuate from year to year the average temperature of the planet as a whole has warmed by about 14 degrees fahrenheit 08 degrees celsius since 1880 this trend is largely driven by increasing human emissions of carbon dioxide and other greenhouse gases into the atmospherethe giss analysis incorporates temperature measurements from 6300 weather stations around the world ship- and buoy-based ocean temperature readings and data from antarctic research stations these measurements are plugged into an algorithm that then estimates average global temperature the computer code for this process is freely available for download from the giss web sitehttp:wwwnasagovpress2015januarynasa-determines-2014-warmest-year-in-modern-recordthis video is public domain and can be downloaded at: http:svsgsfcnasagovcgi-bindetailscgiaid=4252like our videos subscribe to nasa039s goddard shorts hd podcast:http:svsgsfcnasagovvisitunesfor find nasa goddard space flight center on facebook:http:wwwfacebookcomnasagsfcor find us on twitter:http:twittercomnasagoddard
