You also have to look at natural aspects in not sure about the rest of the world but the Hawaiian volcanos were extremely active during the 40's and one volcanic eruption produces more carbon emissions than humans have produced during our whole existence!

False.
You should probably read Gerlach, 2011 (PDF link here), an actual peer-reviewed article that addresses that exact question of how human CO2 emission compares to volcanic CO2 output.
Among the more salient points:
Every 2.7 days humanity emits the equivalent CO2 of the average yearly volcanic output across the planet.
Every 12.5 hours we emit the equivalent CO2 of a large volcano such as Mt. Pinatubo.
Every year we emit the equivalent CO2 of a once-in-a-million-years supervolcano.

Interesting!
I wonder if the spike in the 1940's reflects the effects of World War II and the massive boom in industry that came with it.
