Hiding in the Trees

At http://phys.org/print275123990.html … the Cluster satellites have shown space plasma is full of turbulent swirls – and so called  magnetic reconnection, it is said, has been detected.

At http://phys.org/print275141064.html … we are told that volcanoes can cool global temperatures, presumably by emitting lots of particles into the atmosphere that create an opaque sky, hindering the ability of the Sun to warm the surface of the Earth. However, in a new study published in the journal Geology we learn that changes in climate can affect volcanic activity – and even that volcanic activity closely follows Milankovitch forcings. The study, predictably, involves geological computer modelling in order to reach deep time. Less controversial is the idea that growing ice sheets, or declining ice sheet, might cause tectonic activity.
