What NOAA actually had to say:
- Earth’s temperature has risen by 0.14° Fahrenheit (0.08° Celsius) per decade since 1880, but the rate of warming since 1981 is more than twice that: 0.32° F (0.18° C) per decade.
- 2021 was the sixth-warmest year on record based on NOAA’s temperature data.
- Averaged across land and ocean, the 2021 surface temperature was 1.51 °F (0.84 °Celsius) warmer than the twentieth-century average of 57.0 °F (13.9 °C) and 1.87 ˚F (1.04 ˚C) warmer than the pre-industrial period (1880-1900).
- The nine years from 2013 through 2021 rank among the 10 warmest years on record.

The
year culminated as the sixth warmest year on record for the globe with a temperature that was 0.84°C (1.51°F) above the 20th century average. The years 2013–2021 all rank among the ten warmest years on record. The year 2021 was also the 45th consecutive year (since 1977) with global temperatures, at least nominally, above the 20th century average. Of note, the year 2005, which was the first year to set a new global temperature record in the 21st century, currently ties with 2013 as the 10th warmest year on record and 2010 ranks as the ninth warmest on record.

According to the
2017 U.S. Climate Science Special Report, if yearly emissions continue to increase rapidly, as they have since 2000, models project that by the end of this century, global temperature will be at least 5 degrees Fahrenheit warmer than the 1901-1960 average, and possibly as much as 10.2 degrees warmer. If annual emissions increase more slowly and begin to decline significantly by 2050, models project temperatures would still be at least 2.4 degrees warmer than the first half of the 20th century, and possibly up to 5.9 degrees warmer.
Earth's surface temperature has risen about 2 degrees Fahrenheit since the start of the NOAA record in 1850. It may seem like a small change, but it's a tremendous increase in stored heat.
