CO2: Evil Gas? Or Just Hot Air?

(1) Arctic cooled 50 years, from 1945-1990s: CO2 was rising. CO2 causes arctic cooling? 

(2) CO2 is produced in the oceans & jungle

(3) Real science is about Cause & Effect. CO2 doesn't explain temperature trends in the arctic. Period.

CO2 increased since 1945
CO2 production on Earth (dark areas are high production)

Arctic cooled for 50 years while CO2 increased: opposite correlation

CO2 is produced in oceans & jungle, especially in Africa. More CO2 is produced on the glaciers of Greenland than highly industrialized USA. Ouch! Seems scientists don't truly know much about CO2. Yet they are sure it causes global warming.
