Distinctly Different Trends

Trends in temperature (red bars), (NOAA), tropospheric chlorine (green line) (Solomon, 1999), and ozone depletion (black line) (Staehelin et al., 1998) (WOUDC, 2014) over the past 70 years are distinctly different from trends in concentrations of greenhouse gases such as carbon dioxide (blue dashed line) (NOAA, 2014). Ocean heat content (Levitus et al., 2012) increased with increasing ozone depletion and continues to increase while ozone depletion remains greater than levels prior to 1970. Carbon dioxide levels appear related to ocean heat content, the solubility of CO2 as a function of water temperature.
