A group of scientists will explain on Tuesday Geological field showing in his view that the Anthropocene, the geological period caused by human activity, had already begun. This announcement does not mean that the scientific term that has been circulating among experts for more than two decades will become part of planet Earth’s calendar, beginning about 4.6 billion years ago.
The history of planet Earth is divided into eras, eras, eras and geological eras. We are currently in the Cenozoic era, the Quaternary era, the Holocene era.
According to climate scientists and ecologists, who demand an end to fossil fuels above all, humankind is pushing the planet into a certain environmental crisis with its need for energy and food.
Geologists involved in this cause think that the Anthropocene can be classified as a new era, from which we will leave the Holocene.
Announcement of the geological zone that embodies the Anthropocene is scheduled at 19:00 (5:00 pm GMT) during two scientific conferences in Lille (northern France) and Berlin.
HE The concept of “human age” was first proposed in 2002 by Nobel Prize laureate Paul Crutzen.He estimated that it could be applied from the middle of the 20th century.
It coincides with rising greenhouse gas concentrations, pollution from microplastics, radioactive waste from nuclear testing, and a dozen other markers of our species’ growing impact on the planet.
An international group of geologists began working on this definition ten years ago and selected nine places they believe show the impact of such human activity. Selected locations include a Canadian lake, a Japanese gulf, a crater in China, or an arctic region.
The main difficulty Geologists and scientists defending the cause of the Anthropocene argue that the relative importance of this effect iscompared to the very long chronology of our planet.
The environmental impact of humans is undeniable, but experts from the International Commission on Stratigraphy (ICS) and the International Union of Geological Sciences (IUGS, the highest body on the subject) disagree on characterizing their weight compared to a calendar. It has been changing very slowly over millions of years.
If aliens had landed on Earth a million years from now and studied the rocks and sediment there, would they have detected a significant enough trace of humanity’s transition? The working group meeting this Tuesday gives the clear answer: Humans have already caused the planet to emerge from the Holocene 11,700 years ago, which began after several glacial cycles. Other experts think instead that we are just in an interglacial period, like many others where Earth is currently inhabited. And that includes large changes in the CO2 concentration in the atmosphere..
Confirming the importance of the Anthropocene will force us to reflect on humanity’s impact on the environment.
Crutzen, Nobel Prize winner for describing man-made chemicals that destroy the protective ozone layer. I was hoping that the concept and reality of the Anthropocene would be a cry of warning about the challenges ahead..
“This could mean a paradigm shift in scientific thinking,” he said at a symposium in 2011. In the opinion of this commission’s secretary, Phil Gibbard, “geological phenomenon”.
“The conditions that caused the ice ages (a dozen cycles in the last million years) have not changed, so we can predict that the Holocene was another interglacial period,” this expert warned in 2022.
