Yes but those 440 Gt are naturaly reabsorbed (mostly plant and planktonic emission). If the system was in a natural state it would be a zero sum (aside volcanic outbursts).I was at 440 gigatons of natural emissions for 26 of humqan origin..Granted it´s a little more than 3%..

Climate myths: Human CO<SUB>2</SUB> emissions are too tiny to matter
Carbon dioxide sources and sinks Carbon dioxide levels as measured at Mauna Loa in Hawaii Past and future carbon dioxide concentrations See all climate myths in our special feature. Ice cores show that carbon dioxide levels in the atmosphere have remained between 180 and 300 parts per million...www.newscientist.com
We just added an inflation of +5 to 9% (26 to 40 Gt dependind of estimates) every year.
I don't think it is neglictible anymore in term of increase. That' s also why we are going toward 380 to 400 ppm of CO2 while before industrial era it was around 300 ppm.
Again a not neglictible jump.
We are terraforming earth through that way.
Of course it is not the only way.
