'Co2 is heavier than air and naturally draws back to the lowest point, the sea from when's it came as the earth cools.'
No it doesn't or we would all be walking round in puddles of carbon dioxide and small dogs would keel over suffocated. It is to do with diffusion gradients as the carbon dioxide is dissolved into the ocean water:
Air-sea gas exchange is a physio-chemical process, primarily controlled by the air-sea difference in gas concentrations and the exchange coefficient, which determines how quickly a molecule of gas can move across the ocean-atmosphere boundary. It takes about one year to equilibrate CO2 in the surface ocean with atmospheric CO2, so it is not unusual to observe large air-sea differences in CO2 concentrations. Most of the differences are caused by variability in the oceans due to biology and ocean circulation. The oceans contain a very large reservoir of carbon that can be exchanged with the atmosphere because the CO2 reacts with water to form carbonic acid and its dissociation products. As atmospheric CO2 increases, the interaction with the surface ocean will change the chemistry of the seawater resulting in ocean acidification [which damages ocean ecosysytems].
'O' level chemistry.

By the way sea level has risen and will almost certainly go on rising. Climate change is long term stuff, short term is called 'weather' and in between are variations that need careful analysis to unmask the underlying factors (land up/down lift, - a mere levelling of sea level change since 2014 means nothing - you have ot look at the longer term picture. By the way I think your diagram is a fake to be found on a number of the more virulent climate change denial websites - the 2017 data has yet to be published:
