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: This is due to the greenhouse effect, which is caused by greenhouse gases, which trap heat inside the Earth's atmosphere because of their more complex molecular structure which allows them to vibrate and in turn trap heat and release it back towards the Earth.
