The tree starts to offset CO2 as it starts to grow
This is not true. Ignorance of this simple fact makes me question your education. How much do you know about trees?

And if you are saying that anything planted today will hasten climate change, that's simply not true. Planting trees is not an answer, it's one of the solutions in the complex set of actions we should take.
