Post-World War II
global warming
was from 1975 to 2003
-- there was almost no change
in the global average temperature
from 2003 through the end of 2018.
The UAH weather satellites
capture almost all of that
warming period.
Satellites were not yet in the sky
to capture the lack of global warming
from 1940 to 1975, while CO2 levels
increased rapidly.
