If you think it feels warmer than it used to be, you’re right. The National Oceanic and Atmospheric Administration (NOAA) reports that 2017 was the third hottest year since 1880 when record-keeping began.
A slightly different analysis by NASA ranks 2017 as second hottest, but both agencies agree that the hottest year so far has been 2016.
In Salt Lake City, the average 2017 temperature was 56.1º F which was 3.3º above normal. Around the globe the average temperature was 1.51º F above the 20th century average. During the past 100 years, the Earth surface has warmed by about 2º F, which doesn’t sound like much but the Paris Agreement calls to keep global temperatures rise in this century below 3.6º F above pre-industrial levels.
