You're looking at total atmospheric CO2, which is increasing at an increasing rate. The OP's claim was about CO2 emissions, however, which are increasing at a decreasing rate.
That data lags because it's noisy and because it's measuring the air, which lags production of the CO2. The rate of increase has been increasing as India and especially China have been undergoing economic revolution, but China is also now known to be pivoting on their energy policy. That's already underway, not just planned (https://news.ycombinator.com/item?id=45545644).
No, that is true already. Look at the "rate" tab of the Mauna Kea data, it shows growth on average. Of the rate of CO 2 growth.
