20 million years of CO2 and ice sheet/sea level correlation

When you look at the ice core record, there’s a significant amount of correlation between sea level rise and the amount of carbon dioxide (CO2) in the air at the time. But the ice core record goes back less than a million years. A study published a couple of weeks ago in the journal Science measured proxy data for CO2 concentration in the ocean and compared that data to other data on the stability of ice sheets. The authors discovered that there is strong correlation between the two going back at least 20 million years.
One of the challenges that the authors had was the fact that few available previous studies didn’t show correlation between the amount of CO2 in the air and the global climate prior to the start of ice core data. The authors hypothesized that this was a problem with the other datasets and developed a set of tests to check their hypothesis.
