That's 1.20°C (2.16°F) above their earliest 30-year period, 1880-1909.
If you do a linear fit to their results, the total warming is now 1.06°C (1.91°F), which now rounds to "1.1°C."
But there's now a nontrivial acceleration to the warming, which (for the entire dataset) is 0.016°C/dec2.
More details here. Here's their anomaly map for the month. Notice Siberia.

With La Nina under way, looks like 2020 will come in second behind 2016.
I was a little surprised Sept was a record, with the La Nina already getting underway then.
