Anthropocene: Earth Futures & Geoengineering
Anthropocene: Earth Futures & Geoengineering
💡 Key Takeaways
- Define the Anthropocene and its relevance to Earth system science.
- Identify key human drivers shaping future Earth systems, including climate, land use, biodiversity, and technology.
- Summarize geoengineering approaches (carbon dioxide removal and solar radiation management) and their scientific and governance trade-offs.
- Discuss the ethical, legal, and societal considerations involved in evaluating geoengineering as part of climate action.
❓ Frequently Asked Questions
What is the Anthropocene?
A proposed geological epoch in which humans are the dominant force shaping Earth's surface, climate, ecosystems, and future trajectory through activities like fossil-fuel use, land-use change, and pollution.
What does 'Earth futures' refer to in this topic?
Possible long-term outcomes for the planet under human influence and natural dynamics, including climate change, technological developments, policy choices, and ecological responses.
What is geoengineering?
Deliberate, large-scale interventions in the climate system intended to counteract climate change, such as removing CO2 from the atmosphere (CDR) or reflecting sunlight (SRM).
Why are ethics and governance important in geoengineering?
Because these technologies could affect people differently, involve risk and uncertainty, and require decisions about accountability, funding, and international governance before deployment.
