But rather than using the baselines those agencies employ, Climate Central compared 2016's temperature
anomalies to an 1881 - 1910
average temperature baseline, the earliest
date for which global temperature data are considered reliable.
As far as I can see you got the tied for 10th highest GISTemp
anomaly part right (I assume you have the Land - Ocean Temperature Index in mind, not the land only numbers) but my spreadsheet disagrees with your claim that the

This was defined as the
date when the «globally and annually

Finally, there is a database of 1,732 local annual temperatures
dating 1850 - 2006 AD (also expressed as
