Global temperature data shows that 2018 was one of the warmest years on record in decades. According to The Daily Caller, scientists expect 2018 to rank as the fourth-warmest on record in terms of surface temperature data.
The average global temperature for 2018 is expected to be about 1.4 degrees F above the average of 57.5 degrees.
While most surface temperature surface temperature datasets will show that we had the fourth warmest year, satellite data of lower tropospheric temperatures will show it was only the sixth warmest. A researcher’s explanation:
2018 was the sixth warmest year in the lower troposphere in RSS TLT data. It will likely be the 4th warmest in most surface temperature datasets. Why the difference? El Nino events are more pronounced in the troposphere, elevating 1998 and 2010 above 2018. pic.twitter.com/U4dAcXVYke

By either measure, Earth is warming quickly, and recent years have been warmer than any time for at least 100,000 years.
