Not remotely possible. Numbers don't work.
The carbon from one year's of emissions is 500 to 1000 years of plant growth from back in the Cretaceous or whatever
Can you show me your numbers as to how you arrived at this?
It was from memory. The number from a scientific source is >400.
The fossil fuels burned in 1997 were created from organic matter containing 44 × 1018 g C, which is >400 times the net primary productivity (NPP) of the planet’s current biota.
Today’s average U.S. Gallon (3.8 L) of gasoline required approximately 90 metric tons of ancient
plant matter as precursor material.
To make up from human fossil emissions, you'd need to grow and somehow sequester from decay (no known mechanism today) dozen's of Earths of plants every year.
Oh and don't give me the "CO2 increases plant growth" line. That shows how ignorant your botanical knowledge is. Increasing plant growth does occur but the nutrient level is lower. So you might have more apples but you need to eat more of them DUH!!!!
