Climate Engineering, also known as geoengineering, involves deliberate, large-scale interventions in the Earth’s climate system to mitigate or reverse the effects of global warming. It encompasses two main categories: Carbon Dioxide Removal (CDR), which focuses on extracting greenhouse gases from the atmosphere through methods like direct air capture, afforestation, and ocean fertilization; and Solar Radiation Management (SRM), which aims to reduce incoming solar energy by techniques such as stratospheric aerosol injection or marine cloud brightening. These approaches seek to address climate change challenges but require careful evaluation of potential environmental, social, and ethical implications.

Part 2: 20 Climate Engineering Quiz Questions & Answers
or
1. Question: What is the primary goal of climate engineering?
Options:
A. To reduce greenhouse gas emissions from fossil fuels
B. To deliberately manipulate the Earth’s climate system to counteract global warming
C. To adapt human societies to the effects of climate change
D. To promote renewable energy sources worldwide
Correct Answer: B
Explanation: Climate engineering, or geoengineering, involves intentional interventions to alter the climate, such as removing CO2 or reflecting sunlight, specifically to mitigate the effects of global warming.
2. Question: Which of the following is an example of carbon dioxide removal (CDR) techniques?
Options:
A. Stratospheric aerosol injection
B. Direct air capture and storage
C. Marine cloud brightening
D. Space-based sun shields
Correct Answer: B
Explanation: Direct air capture involves removing CO2 directly from the atmosphere and storing it, which is a key CDR method aimed at reducing atmospheric greenhouse gases.
3. Question: What is solar radiation management (SRM)?
Options:
A. A process to enhance plant growth to absorb more CO2
B. Techniques to reflect a portion of the sun’s radiation back into space
C. Methods for capturing methane from industrial sources
D. Strategies for increasing ocean absorption of CO2
Correct Answer: B
Explanation: SRM focuses on reducing incoming solar energy to cool the planet, such as through aerosols or mirrors, rather than addressing greenhouse gas concentrations directly.
4. Question: Which gas is most commonly targeted in climate engineering for removal?
Options:
A. Methane
B. Carbon dioxide
C. Nitrous oxide
D. Water vapor
Correct Answer: B
Explanation: Carbon dioxide is the primary greenhouse gas responsible for global warming, making it the main focus of many climate engineering efforts like CDR.
5. Question: What are the potential risks associated with stratospheric aerosol injection?
Options:
A. Ocean acidification
B. Disruption of regional weather patterns and ozone depletion
C. Increased biodiversity in forests
D. Enhanced agricultural yields
Correct Answer: B
Explanation: Injecting aerosols into the stratosphere could alter precipitation, cause acid rain, and damage the ozone layer, leading to unintended global weather changes.
6. Question: How does bioenergy with carbon capture and storage (BECCS) work?
Options:
A. By planting trees to naturally sequester carbon
B. By burning biomass for energy and capturing the emitted CO2 for storage
C. By reflecting sunlight with artificial clouds
D. By cooling the oceans to absorb more CO2
Correct Answer: B
Explanation: BECCS combines bioenergy production with CO2 capture technology to remove carbon from the atmosphere while generating energy, making it a hybrid CDR approach.
7. Question: What is a major ethical concern with climate engineering?
Options:
A. It could lead to over-reliance on technology instead of emission reductions
B. It promotes more fossil fuel use
C. It has no impact on biodiversity
D. It only affects developed countries
Correct Answer: A
Explanation: Ethical issues include the risk of moral hazard, where climate engineering might delay necessary emission cuts by providing a perceived quick fix to warming.
8. Question: Which international agreement discusses the potential regulation of geoengineering?
Options:
A. The Kyoto Protocol
B. The Paris Agreement
C. The Convention on Biological Diversity
D. All of the above
Correct Answer: D
Explanation: While the Paris Agreement addresses climate change broadly, the Convention on Biological Diversity specifically calls for a moratorium on geoengineering, and the Kyoto Protocol touches on related emissions.
9. Question: What is the difference between mitigation and climate engineering?
Options:
A. Mitigation focuses on preventing emissions, while climate engineering intervenes after emissions occur
B. They are the same thing
C. Mitigation involves solar radiation techniques
D. Climate engineering is always cheaper
Correct Answer: A
Explanation: Mitigation aims to reduce or prevent greenhouse gas emissions at the source, whereas climate engineering seeks to alter the climate directly to counteract existing warming.
10. Question: Which technique involves enhancing the reflectivity of clouds?
Options:
A. Iron fertilization of oceans
B. Marine cloud brightening
C. Afforestation
D. Direct air capture
Correct Answer: B
Explanation: Marine cloud brightening uses sea salt aerosols to make clouds more reflective, thereby reducing the amount of solar radiation absorbed by the Earth.
11. Question: What could be a side effect of large-scale ocean iron fertilization?
Options:
A. Increased oxygen levels in the atmosphere
B. Algal blooms that deplete oxygen and create dead zones
C. Global cooling without any risks
D. Enhanced coral reef growth
Correct Answer: B
Explanation: Fertilizing oceans with iron to promote algae growth could lead to harmful algal blooms, which consume oxygen and harm marine life, disrupting ecosystems.
12. Question: Why is climate engineering considered a controversial solution?
Options:
A. It is inexpensive and risk-free
B. It may have unforeseen global impacts and unequal effects on regions
C. It has been proven effective in all trials
D. It requires no international cooperation
Correct Answer: B
Explanation: The potential for irreversible environmental damage, geopolitical conflicts, and unequal benefits or harms makes climate engineering highly debated.

Options:
A. They monitor the effects of geoengineering techniques
B. They generate energy for CDR processes
C. They directly inject aerosols into the atmosphere
D. They have no role

Options:
A. It is too effective and inexpensive
B. High energy requirements and costs make it impractical at scale
C. It has no environmental footprint
D. It only works in cold climates
