The correlation matrix and time plots show that these geophysical parameters are all significantly correlated and trending higher over time. More importantly, multiple regression analysis corroborates the findings of the previous studies [1,2]: mid-ocean seismic activity is significantly correlated (p<0.05) with changing temperatures. However, CO2 concentrations, along with NMDP displacements, do not explain a significant percentage of the total variance (p>0.05) when they are included and must be dropped from the analysis. This high degree of multicollinearity is a prominent finding.
