Despite a consistent rise
in atmospheric CO2
over the past 150 years,
there were periods
of global warming,
and there were periods
of global cooling.
of global cooling.
The two largest warming
periods in those 150 years
were between
1910 and 1945, and
1975 and 2005.
The temperature changes
were similar, despite a CO2
increase from 1975 to 2005
that was five times larger
than the CO2 increase
from 1910 to 1945.
You don't have to go back
many years to refute the
climate alarmist claim that
CO2 levels "control" the
global average temperature.
The correlation between
CO2 and temperature
keeps changing !
Climate alarmists
can not explain
this changing
CO2 - Temperature
relationship:
1910 to 1945:
CO2 up +10 ppm
Temperature up +0.5 degrees C.
1946 to 1974
CO2 up +20 ppm
Temperature DOWN (-0.15_ degrees C.
1975 to 2005
CO2 up +50 ppm
Temperature up +0.6 degrees C.
