What is the Anthropocene?
- Coined in 2000, the Anthropocene refers to the present geological time interval characterized by significant human impact on Earth’s ecosystem.
- It emerged with the onset of the Industrial Revolution and encompasses various phenomena such as global warming, sea-level rise, and environmental degradation.
What is the Holocene Epoch?
- The Holocene is the current geological epoch that began approximately 11,700 years ago after the last major ice age.
- It is marked by a relatively stable and warm climate, as well as the development of human civilization.
- The Holocene follows the Pleistocene epoch and is part of the Quaternary period.
Geological Time Scale:
- Geologists divide Earth’s 4.6-billion-year history into slices of time: Eon, Era, Period, Epoch, and Age.
- Each division corresponds to significant events like continental shifts, climate changes, and the emergence of different life forms.
