Solutions Flashcards
What is Geoengineering?
Geoengineering refers to deliberate large-scale intervention in Earth’s natural systems to counteract climate change.
How does Enhanced Weathering help mitigate climate change?
Enhanced Weathering involves accelerating natural weathering processes, such as the breakdown of silicate minerals, to remove carbon dioxide from the atmosphere and store it in rocks.
What is Carbon Capture and Storage (CCS)?
Carbon Capture and Storage (CCS) involves capturing carbon dioxide emissions from industrial processes and storing them underground to prevent their release into the atmosphere.
How does Afforestation contribute to mitigating climate change?
Afforestation involves planting trees on lands that were not previously forested, which helps sequester carbon dioxide from the atmosphere through photosynthesis.
What is Bioenergy with Carbon Capture and Storage (BECCS)?
BECCS involves using bioenergy sources such as plants or algae for energy production and capturing the carbon dioxide emitted during the process for storage underground.
What is Solar Radiation Management (SRM)?
Solar Radiation Management (SRM) aims to reflect a portion of incoming sunlight away from Earth to reduce global temperatures.
What is the concept behind Stratospheric Aerosol Injection?
Stratospheric Aerosol Injection involves injecting sulfate aerosols into the stratosphere to scatter sunlight and enhance the Earth’s albedo, thus cooling the planet.
What is the purpose of Space-based Reflectors?
Space-based Reflectors involve deploying mirrors or other reflective surfaces in space to intercept sunlight and redirect it away from Earth, reducing solar radiation reaching the planet’s surface.
How does Marine Cloud Brightening work?
Marine Cloud Brightening involves spraying seawater into low marine clouds to increase their reflectivity, thereby reflecting more sunlight back into space and cooling the Earth.
How does Land-based Albedo Modification help mitigate climate change?
Land-based Albedo Modification involves increasing the reflectivity of surfaces such as rooftops or agricultural land to reduce the absorption of solar radiation and mitigate warming.
How does Bioenergy with Carbon Capture and Storage (BECCS) differ from traditional bioenergy?
BECCS differs from traditional bioenergy by capturing and storing the carbon dioxide emitted during energy production, thus achieving negative emissions.
What are the potential risks associated with Geoengineering methods?
Potential risks of Geoengineering methods include unintended environmental consequences, geopolitical tensions, and ethical concerns regarding their deployment and impacts.
What are the challenges in implementing Carbon Capture and Storage (CCS)?
Challenges in implementing CCS include high costs, technological limitations, and concerns about the long-term integrity of underground storage sites.
How can international cooperation help address the challenges of Geoengineering?
International cooperation is essential for coordinating research, establishing governance frameworks, and addressing transboundary impacts and concerns associated with Geoengineering.
What are the limitations of Enhanced Weathering as a climate mitigation strategy?
Limitations of Enhanced Weathering include the need for large-scale deployment, potential impacts on soil and water quality, and uncertainties regarding its effectiveness and feasibility.
