How many gigatons Gt of carbon dioxide are released into the atmosphere per year?
9 Gigatons
There are about 5,100,000,000,000,000,000,000 grams of air in the atmosphere, and using unit conversions and some algebra, we know that 9 Gigatons of Carbon per year is approximately the same as 4 ppm per year.
