Humanity has etched its way into Earth’s geology, atmosphere and biology with such strength and permanence, a special team of scientists figures we have shifted into a new geologic epoch, one of our own creation. It’s called the Anthropocene
is sometime around 1950 to 1954. The specific date will be determined soon, probably by levels of plutonium in new measurements from the bottom of the special lake site.
There are distinct and multiple signals starting around 1950 in Crawford Lake showing that “the effects of humans overwhelm the Earth system,” said Francine McCarthy, a committee member who specializes in that site as an Earth sciences professor at Brock University in Canada. The Anthropocene — derived from the Greek terms for ‘human’ and ‘new’ — shows the power and the hubris of humankind, several scientists told The Associated Press.
This puts the power of humans in a somewhat similar class with the meteorite that crashed into Earth 66 million years ago to kill off dinosaurs, starting the Cenozoic Era and the what is sometimes called the age of mammals. But not quite. That meteorite started a whole new era, scientists propose humans started a new epoch which is a much smaller geologic time period.
