Formal ratification of the subdivision of the Holocene Epoch (Quaternary System/Period): two new Global Boundary Stratotype Sections and Points (GSSPs) and three new Stages/subseries. The abrupt climate change near 4,400 yr BP on the cultural transition in Yuchisi, China and its global linkage.

But the belt of “subduction metamorphic rocks” is paralleled by a second belt of metamorphic rocks, with a higher temperature signature, the rocks forming in association with the accompanying volcanic arc.

Note the small “BIF blip” that coincides with the timing of the Neoproterozoic Snowball Earth glaciations. (Callan Bentley figure, redrawn from Klein (2005)) It suggests that the first animals (which were very cool) were sucking all the oxygen out of the oceans.

Discuss how the Earth’s spheres interact through flows of energy and materials. Identify ways that changes in one sphere can effect changes in other spheres and even lead to changes in dynamic equilibrium of the entire Earth system. Discuss how remote sensing data is important in understand the complexity of the Earth system. Understand the importance of time scales for Earth systems research.
