Chart from Climate Central: The running average of global temperatures throughout 2016 compared to recent years. Each month shows the average of that month’s temperature and each month before it
Earth is nearing the end of the the third record-breaking hot year in a row. 2014 was the hottest year ever, but was beaten by 2015. Now 2015’s heat takes second place to 2016’s heat.
2016’s record-breaking heat too fuel in part from an El Nino through the first nine months of the year; with a La Nina weather pattern developing now, there will be some cooling, but the cooling will not be enough to keep 2016 from being the warmest year ever recorded in human history.
Notes on this milestone can be found in several places; Climate Central’s explanation covers it succinctly.
The National Oceanic and Atmospheric Administration released its temperature data through the end of October on Thursday and found that for the year-to-date, the global average temperature is 1.75°F above the 20th century average of 57.4°F. That puts the year 0.18°F ahead of last year, the current hottest year titleholder, with just two months to go.
“It’s likely that we will end up as record warmest,” Jessica Blunden, a climate scientist with NOAA’s National Centers for Environmental Information, said during a press teleconference.
October itself tied as the third warmest in 136 years of record-keeping, coming in at 1.31°F (0.73°C) above the 20th century average of 57.1°F, according to NOAA. (NASA, which uses a different baseline and slightly different methods, put October in second place.)
September was the first month of the year to not be record warm (it came in second place), as temperatures began to cool slightly with the demise of El Niño and the move toward La Niña. It ended a streak of 16 consecutive record-setting months, itself a record.
Maybe more shocking, it’s been 115 years since we had a record cold year, according to Climate Central.
In fact, global temperatures have been above-average for 382 months in a row by NOAA’s reckoning, going all the way back to the Reagan administration. To find a record cold month requires going all the way back to February 1929. The last record-cold year was even further back, in 1911.
382 months. Anyone under the age of 31 has never experienced a single month of temperatures as low as the 20th century average, in their lifetime. A generation has been raised with global warming climate change as the norm. How will that affect voting patterns and public opinion to change government policies?

The United States and North Africa were also particularly warm. The largest area of cooler than average temperatures stretched across Russia. (Source: NASA GISS)
