The large volcanic eruptions that occurred during the Little Ice Age and the Post-Holocene Climate Optimum period during the last 8,000 years were associated with grand solar minima or maxima of sun spot numbers. Such large magnitude volcanic eruptions had disastrous consequences on global agriculture through cold, ice, drought, and flooding. Scientists tell us that if a Laki-like volcanic eruption (Iceland, 1783) occurred today, the global crop production losses would be in the region of one year’s food supply for one-third of the world’s population. There is no publicly available plan (energy, water, food, emergency) to manage a large magnitude volcanic eruption because the Intergovernmental Panel on Climate Change dismissed its prospect in its 5th Assessment Report climate predictions and risk assessments provided to our governments.
