Environmental Science: Planetary Boundaries

What is the 'Anthropocene'?

• A period where global systems will be defined by human activity

• A historically recent period of stable geological/environmental conditions

• A strategy for accurately measuring global temperature shifts

• The net energetic consumption of the Earth's human population
