They were all above average.
Each year was warmer than the previous year.
They were all below average.
Temperatures fluctuated near the average temperature.
During this time period, global temperatures were generally fluctuating around the average temperature. There were some years that were slightly above average and some years that were slightly below average, but overall there was no consistent trend towards warming or cooling during this time period.
