This abundantly illustrated book provides a concise overview of our understanding of the entire mantle, its evolution since early differentiation and the consequences of superplumes for earth surface processes. The book’s balanced authorship has produced a state-of-the-science report on the emerging concept of superplumes. This presents a new concept to explain catastrophic events on Earth through geologic time.

Superplumes: Beyond Plate Tectonics

We are at the terminal point of the warm interglacial period, and the next glacial age may anytime start. The first step of the global cooling is predicted by the author to come in 2035, when the food production will surely decrease. The population is expanding and the shortage of food and drain of natural resources result in the limits to the growth of the human society. It was predicted by the Rome Club (1972) that The Limits to Growth would come in 2020. All these conditions together corroborate to bring a severe crisis to human beings in near future. If the earth would be meeting warming in near future as predicted by IPCC, then the crisis would be mild. However, it is not the case. The atmospheric temperature of the earth will surely become cold, because most of major controlling factors of the atmospheric temperature, i.e., solar activity, cosmic rays, and geomagnetism are changing in a way to the cooling. The effect of carbon dioxide gas only cannot be too much evaluated. The effort of decreasing carbon dioxide gas is important in the sustainability of our limited resources, however, we have to seriously consider the measures for the approaching crisis of global cooling and the limits to growth.
