The scientists emphasize that the rapid expansion of human activities since the industrial revolution has now generated a global geophysical force equivalent to some of the great forces of nature.
"We are entering the Anthropocene, a new geological era in which our activities are threatening the Earth’s capacity to regulate itself. We are beginning to push the planet out of its current stable Holocene state, the warm period that began about 10,000 years ago and during which agriculture and complex societies, including our own, have developed and flourished," says co-author Professor Will Steffen, Director of the ANU Climate Change Institute at The Australian National University. "The expanding human enterprise could undermine the resilience of the Holocene state, which would otherwise continue for thousands of years into the future."First assumption, the Earth regulates itself.
Second assumption, that the author of this piece knows what the future holds.
Neither are presented with evidence, theory and the peer reviewed process normally required for scientific knowledge to be accepted.
This isn't science, it is religion.
