The viewpoint of this paper is based on earth system science; that is, every sphere-layer of the earth is considered as a subsystem, and each subsystem of them is combined to one another and keeping interacting. According to the observation of intraplate earthquakes, high intensity volcano activities, and plume phenomenon, the impact of greenhouse effect is not only on atom sphere, hydrosphere, biosphere, and lithosphere, but also on the mantle, because the influence of greenhouse effect had changed the gradient of temperature in the mantle.
