SUMMARY:The Great Migration:  3.8 billion years of carbon circulation thro
 ugh Earth - Matthieu Galvez\, ETH-Zurich

DESCRIPTION:Over geological time\, the carbon cycle has connected surface 
 ecosystems to the interior of the Earth. The complexity of the carbon cycl
 e arises from at least two key properties: it is an evolved system — an 
 emergent macroscopic structure shaped by biological evolution — and it e
 volves on a dynamic planet. For this reason\, its complexity owes both to 
 tectonic and biochemical factors. I will discuss\, in particular\, recent 
 advances in understanding the mechanisms\, longevity\, and planetary singu
 larity of the weak but sustained leaks of organic carbon between the surfa
 ce\, the lithosphere and the mantle of our planet through time.
