Not according to the RSS and UAH satellite tropospheric data sets.
The MSU and AMSU sensors have issues, but still have wider coverage and superior accuracy to the ground station data the NOAA is using. Additionally, RSS and UAH are two different teams, with different methodologies, and using different sensors, with corroborating data.

[EDIT] I'm absolutely wrong. Both the RSS and UAH data confirm that November is the hottest November in the sattelite record also.
Thanks jacobolus for pointing this out (and making sure I stop assuming the NOAA is exaggerating on its hottest month claims.)
- jacobolus 11y agoHere are some of the relevant rows from your second link (hottest values in one of the “GLOBAL” columns). I’m not sure I completely understand what the columns all mean though. Can you elaborate a bit?

I’m not sure what I should be looking at.
- merpnderp 11y agoWow, I totally missed that. November was incredibly warm. This will bring up the long term trends significantly. Looks like you excerpted the UAH data which is year, month, global average, Northern Hemisphere, Southern Hemisphere, Tropics, not sure what No.Days is for, and then the 12 month running mean for each of the previous. I'm just so used to the NOAA saying "Warmest month ever" and it being contradicted by the MSU/AMSU data, it didn't even occur to me they were right. Thank you so much for double checking me.
- Roodgorf 11y agoAccording to that then it looks like the 12 month running average is significantly lower, is that to be expected/in line with predictions/at all statistically relevant? I'm still not sure I actually understand what those numbers represent. EDIT: After jacobolus updated with more columns and checking some other years from the link provided, that does not actually appear to be a trend. My apologies.
