Geology Today

Join me for discussion of current trends in geology, and related disciplines.  Post articles, thoughts, reflections, questions etc. about developments in the study of the Earth.  What is the latest on global warming?  What new fossil finds are rewriting the evolutionary history of life (including our own)?  What are the latest developments in astrobiology (search for life outside of Earth)?  What is the latest research on volcanoes, and Earthquakes?  Anything related to the study of the Earth is fair game here, so join in.  =)
