I am extremely curious about the error bars on these numbers. Are we really measuring the temperature in enough places around the globe with 0.01 degree resolution to make this a meaningful statement?
The raw data is available at:

Putting all that together into a single temperature requires a model. The error analysis of the model is on their web site. There's certainly more than enough data to justify four significant figures.
(The weird part: the authors of the report are both prominent climate change deniers. One says that the problems are real but not man-made; the other says that the problems are real and man-made but not actually a problem. They are the guys who run the satellite and integrate the data.)

And that's before you get to the way they rewrite the past in the temperature databases. It leads to problems like this:
Jeff Berardelli, WFLA-TV (Tampa Bay) Chief Meteorologist and Climate Specialist: “In case you missed it. The temperature soared as high as 100 degrees in the Northwest Territories on Saturday, the hottest temperature ever measured north of 65 degrees latitude in the Western Hemisphere”. Tough keeping up with all this climate chaos.”

100 degrees, hottest ever measured in north of 65 degrees latitude. A factual statement?
No, because it's not true. It reached 100F at Fort Yukon (66.6 degrees latitude) in 1915, according to government logbooks since erased from their websites:

This happens because climatologists engage in data fraud. They not only constantly change how they combine individual readings into global aggregates, but also rewrite the temperature history of every single weather station too. It leads to constant 1984-esque dystopian events, like trusted news sources claiming a new record has been broken when you can find records of that "record" having been previously already been reached or exceeded in newspaper archives and old documents.
