Since 1870, average global sea level has risen by about 8 inches. The below 1 point graph shows predictions based on the current rate of sea level rise and the
current rate of CO2 increase. The red Maximum line shows a worst-case
scenario if nothing is done to slow down the emissions of CO2, as
predicted by the National Oceanic and Atmospheric Administration. Why
exactly would sea levels be higher if CO2 increases? *
