Científicos creen que una nueve época comenzó en la década de 1950

July 14, 2023 - Un equipo de científicos cree que debe agregarse una nueva época a la
escala de tiempo geológico a partir de la década de 1950 – con el nombrede Antropoceno – debido al enorme impacto de la humanidad sobre la Tierra.

A team of scientists think a new epoch should be added to the geological time scale beginning in the 1950s.

Called the Anthropocene (from the Greek for “human” and “new”), the proposed epoch started between 1950 and 1954 when humans began impacting the world by burning fossil fuels, detonating nuclear weapons and dumping fertilisers and plastics into the environment.

A key indicator of these actions can be measured at Crawford Lake, near Toronto in Canada, where the annual effects of human activity on the soil, atmosphere and biology are preserved in its layers of sediment.

Scientists aim to determine a specific start date of the Anthropocene by measuring plutonium levels at the bottom of the lake.
