Abstract.  Global surface temperature in 2018 was the 4th highest in the period of instrumental measurements in the Goddard Institute for Space Studies (GISS) analysis.  The 2018 global temperature was +1.1°C (~2°F) warmer than in the 1880-1920 base period; we take that base period as an estimate of ‘pre-industrial’ temperature.  The four warmest years in the GISS record all occur in the past four years, and the 10 warmest years are all in the 21st century.  We also discuss the prospects for near-term global temperature change.
