The Anthropocene Epoch in Cosmic Evolution - David Grinspoon (SETI Talk
Δημοσιεύτηκε στις 19 Φεβ 2015
Informed
by comparative planetology and a survey of the major episodes in Earth
history, Dr. Grinspoon will offer a taxonomy of planetary catastrophes
meant to illuminate the unusual nature of the “Anthropocene”, the
current epoch of human-driven planetary-scale changes, and reframe our
current environmental and technological predicaments as part of a larger
narrative of planetary evolution. This saga has now reached the pivotal
moment when humans have become a dominant force of planetary change,
and geological and human history are becoming irreversibly conjoined. Is
this a likely or even inevitable challenge facing other complex life in
the universe? Possible implications for exoplanet characterization and
SETI will be considered, as well as the choices our civilization faces
in seeking to foster a wisely managed Earth.
