"There have now been 360 consecutive months when the global temperature was above the 20th century average."

360 months = 30 years. 1200 months = 100 years = 20th century.

Half of the 20th century temps were above average. Half were below average. That's what "average" means.

I think we can figure out the relative significance of this.

Half of the 20th century temps were above average. Half were below average. That's what "average" means.

No, that's a median.

Here's an example using this series of numbers: 1,2,3,4,5,100,101.

The median is 4.
The mean/average is the sum (216) divided by 7 = 30.86.
