Only 42 % of the emitted CO2 stays in the atmosphere[1], the rest is soaked up by land and ocean. The article only relates to the CO2 in the atmosphere.
That factor changes "5 years" to 12. Which is still less than that because our emissions still increase.
I don't suggest that trees aren't important, just that they are definitely still just a tiny part against what we put in the atmosphere at the moment if we contiue to do so (and we do too little to change that).
