Cooling Caused by Volcanic Eruptions Appears to Accumulate

Modeled sea level change suggests an accumulation of cooling caused by large volcanic eruptions (Krakatoa  and  Pinatubo VEI =6, Agung and El Chichón VEI=5). The annual time series is shown of global-mean sealevel change due to thermal expansion using the HadCM3 model with volcanic forcing only. The curve is shifted vertically to start from zero in 1860 and divided by five. Based on Figure 5 in Gregory et al. (2006)
