P2U2 12Adaptation and Mitigation Strategies e.g. Geo-engineering

What is biogas and how is it used?

• Biogas is a type of fossil fuel used for heating homes.

• Biogas is methane collected from decomposing organic waste, used to produce energy.

• Biogas is a renewable energy source derived from solar power.

• Biogas is a chemical compound used in fertilizers.

What is geoengineering?

• Methods designed to directly address the impacts of climate change.

• A technique to increase global temperatures.

• Strategies to reduce carbon emissions.

• Natural processes that enhance biodiversity.

What are the two main types of geoengineering?

• Carbon Dioxide Removal (CDR) and Radiation Management (RM)

• Solar Panel Installation and Wind Turbine Development

• Nuclear Energy Production and Hydroelectric Power

• Recycling and Waste Management

What are biofuels and how are they used?

• Biofuels are derived from fossil fuels and are used to power vehicles.

• Biofuels are derived from plants and are considered nearly 'carbon neutral' because the plants absorb CO2 as they grow.

• Biofuels are synthetic fuels made from chemicals and are used in industrial processes.

• Biofuels are a type of renewable energy that comes from nuclear reactions.

What are giant space mirrors in the context of RM?

• Mirrors placed in space to reflect sunlight away, cooling the planet.

• Mirrors used to enhance the brightness of stars in the night sky.

• Mirrors designed to capture solar energy for use on Earth.

• Mirrors that create artificial moons for aesthetic purposes.

How can switching to renewable energy reduce CO2 emissions?

• By replacing coal-burning power plants with renewable sources like wind and solar, or nuclear power.

• By increasing the use of fossil fuels in energy production.

• By promoting the use of electric vehicles only.

• By encouraging deforestation to create more space for solar panels.

How does reforestation help in reducing CO2?

• It increases the amount of CO2 in the atmosphere.

• It prevents soil erosion and improves water quality.

• It involves planting more trees, which absorb CO2 through photosynthesis, acting as a carbon sink.

• It reduces the need for fossil fuels by providing alternative energy sources.

What is Carbon Dioxide Removal (CDR)?

• A process that increases carbon dioxide emissions.

• Strategies focused on removing carbon dioxide (CO2) from the atmosphere.

• A method for capturing and storing oxygen.

• Techniques for enhancing carbon dioxide production.

What is cloud seeding with aerosols in the context of RM?

• Releasing aerosols from planes to form clouds that reflect sunlight away from Earth.

• Using chemicals to enhance rainfall in agricultural areas.

• Injecting water vapor into the atmosphere to create storms.

• Deploying drones to monitor weather patterns.

What is Radiation Management (RM)?

• RM involves strategies aimed at reflecting sunlight back into space to reduce the heat that reaches Earth's surface.

• RM is a method for increasing the absorption of solar energy by the Earth's surface.

• RM refers to the management of radioactive waste in nuclear power plants.

• RM is a technique used to enhance the greenhouse effect for agricultural purposes.
