Unfortunately
using global average surface air temperatures as a measure of total warming ignores the fact that most of the heat (more than 93 %) goes into our oceans, which continue to warm without any sign of a pause, as you can see below.
Not exact matches
The
global temperature records
use a blend of
air and sea -
surface temperatures, while
global average temperatures from climate models typically
use just
air temperatures.
There is to mention, that the globally
average temperature of the
air near the
surface (y = T) of about 288 K was calculated
using the definition of a
global average, too.
However, for changes over time, only anomalies, as departures from a climatology, are
used, most commonly based on the area - weighted
global average of the sea
surface temperature anomaly and land
surface air temperature anomaly.
