Writer Fuel: Nuclear Testing Set Off a New Age on Earth – the Anthropocene

Nuclear weapons testing in the 1950s and early 1960s left the first obvious and indelible marks of “overwhelming” human activity on Earth, and these events may signal the beginning of a new geological epoch known as the Anthropocene, geologists say.

Fallout from these tests snowed down from the atmosphere and became trapped in the earth as layers of sediment rich in a radioactive form of plutonium, called plutonium-239.

Scientists argue that blankets of plutonium-239-rich sediment at the bottom of a small lake in Canada present the earliest tangible record of human activities shifting the balance of natural systems — which is why they’re naming this potential new epoch “anthro” after humans.
