We are burning the equivalent carbon of millions and millions of years of plant growth, trapped in fossil. Our current available plant mass, even if we cover every square inch of the earth with vegetation, cannot absorb millions of years of carbon. As another poster has replied, plants also release that carbon back when they decompose, unless they are buried. The only answer to digging up millions of years of dead organic matter and burning it is to suck it back into the ground, or fire it into space, or anything else that actually removes it from being recycled in the biosphere.
