Planet H/eaters - a global
warning
Dr Andrew Glikson is an Earth Scientist at the
Australian National University, with a 40 year record in geological surveys in
inland Australia and studies of the early history of the Earth, origin of
continents and oceans, and the role of volcanic eruptions, asteroid impacts and
greenhouse effects in terrestrial evolution. His talk "Planet H/eaters - a
global warning" will explore the nature and origin of the current climate
change, the consequence of anthropogenic combustion of the carbon products of
more than 400 million years of biological evolution. The imbalance created
between the innovative powers of an overgrown human neocortex and the primitive
mammalian brain threatens advanced life forms on Earth. Random creativity
results in, often destructive, technological determinism. On the other hand, the
strongest force on Earth remains the Life Force, which has survived for
four billion years despite major volcanic, tsunami, asteroid/comet impacts, ice
ages and greenhouse episodes.
