Decrease in Benthic O18 Corresponds with Elevated CO2 in the Past 800,000 years

---

This diagram shows the excellent relationship between atmospheric CO2 increase, sea level increase and O18 decrease is sea shell foraminifera (forams) for the past 800,000 years.  Forams are foraminifera that died and deposited their shells in sea sediment during the same time periods.
Increased mortality of forams was possibly caused by increased acidification of oceans due to high atmospheric CO2.  
The excellent correlation of these 3 sets of data corroborates the relationship between high atmospheric CO2, acidification of oceans, greenhouse effect, global warming, melting of ice caps and corresponding sea level rise.
As you can see by how well the data correlate, increasing atmospheric CO2 beyond the current average of 400 ppm has far reaching consequences.
