I don't know how they came up with this sentence. I'm sure it is true in some sense of the word "true." But just look at the data:

Perhaps OP is talking about some older data before the cutoff of this graph.

Edit: the Guardian article posted elsewhere shows the opposite:

Amusingly, the Guardian illustration is credited to the same person who wrote the article I cite: Zeke Hausfather.

It is due to the adjustments of the ocean temperature data. The SST data has been adjusted upward. Due to the adjustments the global temperature is estimated to be warmer in the past than the raw data show (http://variable-variability.blogspot.com.au/2015/02/homogeni...)
