Of course if the recent sea level rise has been 0 and it continues so, it will never reach the level depicted in the National Geographic. Whereas in previous years the temperature records have been shown unadulterated, now we have presentation of a single figure for each decade; surely an attempt to mislead rather than inform

The concentration of carbon dioxide (CO2) in Earth's atmosphere determines its contribution to the greenhouse effect and the rates of plant and algal photosynthesis. Even if equilibrium is reached, including dissolution of carbonate minerals, the increased concentration of bicarbonate and decreased or unchanged concentration of carbonate ion will give rise to a higher concentration of un-ionized carbonic acid and dissolved carbon dioxide gas
