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

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).
