This is a comparison of the CO2 concentrations measured in air bubbles frozen in the ice cores of Antarctica dating back 400,000 years to past sea levels. You can see that every rise in CO2 has a corresponding rise in sea level that is significant.
This is because with every great rise in CO2 in the atmosphere, there was a corresponding Global Warming Greenhouse Affect causing glacial and ice cap melting. If the CO2 rise was significant enough, Global Warming was enough to completely melt the ice caps raising sea levels more than 100m (greater than 300 feet).
Keep in mind that the rise in sea level during these inter-glacial warming periods was achieved with CO2 concentrations below 300 ppm. In a previous blog post, I showed you that an average of 400 ppm atmospheric CO2 was recorded in Hawaii and with the current rate of fossil fuel consumption, it is likely to head much higher.
With CO2 concentrations heading higher than 400m what massive sea level rise can we expect? Well, judging by the past 800,000 years of data, sea level rise is likely to be massive, and likely to be higher than ever recorded because we are surpassing even 400 ppm in the coming years.
Higher sea levels also bring, bigger storms and higher associated storm surges.
