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.
