October a Scorcher: biggest monthly anomaly on record, from both NASA and JMA

A few days ago I learned that JMA (the Japan Meteorological Agency) had released their global temperature data for October, according to which this year’s October beat the pants off any preceding:

I wasn’t sure what other organizations would report, but NASA just released their October update — and this year’s October beat the pants off any preceding:

...
By the way, this month wasn’t just the hottest October temperature anomaly on record in NASA data. It was the hottest month, period.

This is the first time the NASA monthly anomaly has gone over 1 degree Celsius above the 1951-80 base period. And no other month in the JMA record has reached this 0.53C anomaly above their 1981-2010 baseline.

And I thought for sure I'd exit before the worst of it hit. Lately, I'm not so sure.

Japan says just over 0.5c anomaly and NASA says 1c anomaly. Which is more accurate?

On edit, I see...different baselines. Why does NASA use a period that had a cooling trend in it? If both have a record going back to the late 1800's, why not use the full period to establish the baseline? Wouldn't it be more accurate when determining anomalies?

Japan's current baseline can only have been used very recently, since it goes up to 2010. If they were producing global anomaly measurements like this before that, they'd have had to use an earlier baseline; perhaps they updated it so that the mid 90s figures that Kyoto is measured against are roughly in the middle of it. NASA's baseline may reflect the period they initially felt confident with for number of measurements after WW2.
