Study: plate tectonics modulates volcanic activity, which in turn modulates climate forcings

From Rice University comes this study that tries to equate an analog circuit component onto a climate forcing component. It is an interesting approach. The idea that plate tectonics serves to modulate episodic volcanic activity also makes sense. Volcano location … Continue reading

Volcanic Disruptions

Guest Post by Willis Eschenbach The claim is often made that volcanoes support the theory that forcing rules temperature. The aerosols from the eruptions are injected into the stratosphere. This reflects additional sunlight, and cuts the amount of sunshine that … Continue reading
