2016 - “Hottest Year On Record” — 2016. Atmospheric CO2 on Nov. 14, 2016 = 402.61.
“Preliminary data for October 2016 indicate that global temperatures are at a sufficiently high level for 2016 to remain on track for the title of hottest year on record. This would mean that 16 of the 17 hottest years on record have been this century (1998 also in 20th Century).”

U. N. World Meteorological Organization (WMO), press release, November 14, 2016.
The World Meteorological Organization (WMO) recently briefed United Nations Secretary-General Ban Ki-moon on global warming data that indicates 2016's global temperatures are approximately 1.2 degrees Celsius above pre-industrial levels. Other 2016 record-breaking climate change indicators show concentrations of CO2 in the atmosphere now at 402.61 parts per million continue to increase to new records. Arctic sea ice remains at low level and the Greenland ice sheet melted earlier and longer. Good news: Earth System Science Data (ESSD) reports slow down in CO2 emissions from fossil fuels and industry to a 0.2% increase in 2016. See: WMO. Also see: Daily CO2 and ESSD.
