While I appreciate the sentiment, I think it’s unrealistic to expect the greenhouse gas concentration in the atmosphere to decrease. For that, we already would need net 0 emissions AND some sort of carbon capture system in place.
For now, what must decrease is greenhouse gas emissions, and the article admits that that is what happened (but the decrease was so low it could be attributed to natural fluctuations).
There are natural systems capturing carbon as well. The problem is that it takes 10,000 years or so to capture all humans have released to date. So zero emissions would already lower concentration over time.
