My amateur spreadsheet tracking and projecting the monthly NASA GISS values suggests that while 2018 and 2019 are likely to be cooler than 2017, they may also be the last years on Earth with
global average land and ocean
surface temperature anomaly
below 1C above pre-industrial
average (using 1850 - 1900 proxy).
