claim: It was the post war  industrialization that caused the rapid rise in global CO2 emissions,  but by 1945 when this began, the Earth was already in a cooling phase  that started around 1942 and continued until 1975.
evidence: The average global temperature on Earth has increased by about 0.8° Celsius ( 1.4° Fahrenheit ) since 1880; Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20 °C per decade.
