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.
New Orleans Saints running back Alvin Kamara pleaded no contest to a misdemeanor charge, his attorney said Tuesday., nuclear bomb detonations spotted in soil around the globe, plastics and nitrogen from fertilizers added on land and dramatic changes to species that make up the rest of the Earth characterize the new epoch, scientists said.The idea of the Anthropocene was proposed at a science conference more than 20 years ago by the late Nobel Prize winning chemist Paul Crutzen.
“The remarkably preserved annual record of deposition in Crawford Lake is truly amazing,” said U.S. National Academies of Sciences President Marcia McNutt, who wasn’t part of the committee. “It is just as important to the beginning of an era dominated by one category of Earth species as it is to mark the end.”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.Geologists measure time in eons, eras, periods, epochs and ages.

Scientists now say a new epoch – the Anthropocene, marked by human impact on Earth – began in 1950sThe burning of coal, oil and gas that’s changing Earth’s climate and atmosphere, nuclear bomb detonations spotted in soil around the globe, plastics and nitrogen from fertilizers added on land and dramatic changes to species that make up the rest of the Earth characterize the new epoch, scientists said.
