Primary Climate Trends

Increased SO2 pollution (dotted black line) does not appear to contribute to substantial global warming (red line) until total column ozone decreased (black line, y-axis inverted), most likely due to increasing tropospheric chlorine (green line). Mean annual temperature anomaly in the Northern Hemisphere (NOAA, 2014) (red line) and ozone (black line) are smoothed with a centered 5 point running mean. OHC is ocean heat content (dotted purple line).
