Another year, another record:
Earth’s 2016 surface temperatures were the warmest since modern recordkeeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).
Globally-averaged temperatures in 2016 were 1.78 degrees Fahrenheit (0.99 degrees Celsius) warmer than the mid-20th century mean. This makes 2016 the third year in a row to set a new record for global average surface temperatures.
Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year – from January through September, with the exception of June – were the warmest on record for those respective months. October, November, and December of 2016 were the second warmest of those months on record – in all three cases, behind records set in 2015.
The NOAA is much more conservative:
During 2016, the average temperature across global land and ocean surfaces was 1.69°F (0.94°C) above the 20th century average. This was the highest among all 137 years in the 1880–2016 record, surpassing the previous record set last year by 0.07°F (0.04°C). The first eight months of the year had record high temperatures for their respective months. Since the start of the 21st century, the annual global temperature record has been broken five times (2005, 2010, 2014, 2015, and 2016).
No wait, they’re saying the same thing as NASA (although NASA says 2016 was .09°C above 2015).
If you look at the temperatures since 1880 there is no obvious pattern (the data is from here, Credit: GISTEMP Team, 2017: GISS Surface Temperature Analysis (GISTEMP). NASA Goddard Institute for Space Studies. Dataset accessed 20Y17-01-18at https://data.giss.nasa.gov/gistemp/):
Well, there’s no obvious pattern if you’re paid to see no pattern.
