Global warming refers to the long-term rise in Earth’s average surface temperature, primarily driven by human activities that release greenhouse gases into the atmosphere. These gases, such as carbon dioxide from burning fossil fuels and methane from agriculture and landfills, trap heat from the sun, creating a blanket effect that warms the planet. As a result, glaciers and polar ice caps are melting at unprecedented rates, leading to rising sea levels that threaten coastal cities and low-lying islands. Extreme weather events, including more intense hurricanes, droughts, and heatwaves, are becoming more frequent, disrupting ecosystems, agriculture, and human health. Biodiversity is declining as species struggle to adapt to rapidly changing climates, and ocean acidification is harming marine life. Addressing global warming requires urgent global action, including transitioning to renewable energy sources, reforestation efforts, and policies to reduce emissions, to mitigate its devastating impacts and preserve the planet for future generations.

Part 2: 20 global warming quiz questions & answers
or
1. Question: What is the primary cause of global warming?
Options:
A. Volcanic eruptions
B. The greenhouse effect from human activities
C. Solar flares
D. Natural climate cycles
Answer: B
Explanation: The greenhouse effect, intensified by human activities like burning fossil fuels and deforestation, traps heat in the Earth’s atmosphere, leading to global warming.
2. Question: Which gas is the most significant contributor to the enhanced greenhouse effect?
Options:
A. Oxygen
B. Carbon dioxide
C. Nitrogen
D. Methane
Answer: B
Explanation: Carbon dioxide, mainly from fossil fuel combustion and land-use changes, is the largest contributor to the enhanced greenhouse effect, as it absorbs and re-emits infrared radiation.
3. Question: How does deforestation contribute to global warming?
Options:
A. By increasing oxygen levels
B. By releasing stored carbon dioxide into the atmosphere
C. By cooling the planet through shade
D. By reducing water vapor
Answer: B
Explanation: Trees absorb carbon dioxide; when they are cut down, the stored carbon is released, increasing atmospheric CO2 levels and amplifying global warming.
4. Question: What is a major effect of global warming on ocean levels?
Options:
A. Decreased evaporation
B. Rising sea levels due to melting ice caps
C. Increased ocean salinity
D. Reduced wave activity
Answer: B
Explanation: Global warming causes polar ice caps and glaciers to melt, adding more water to the oceans and leading to higher sea levels, which threatens coastal areas.
5. Question: Which international agreement aims to limit global temperature rise to below 2 degrees Celsius?
Options:
A. Kyoto Protocol
B. Paris Agreement
C. Montreal Protocol
D. Rio Convention
Answer: B
Explanation: The Paris Agreement, adopted in 2015, commits countries to limit global warming to well below 2 degrees Celsius, preferably to 1.5 degrees, through emission reductions.
6. Question: What role do fossil fuels play in global warming?
Options:
A. They cool the atmosphere
B. They release greenhouse gases when burned
C. They increase biodiversity
D. They reduce acid rain
Answer: B
Explanation: Burning fossil fuels like coal, oil, and gas releases carbon dioxide and other greenhouse gases, which trap heat and drive global warming.
7. Question: How does global warming affect weather patterns?
Options:
A. It makes weather more predictable
B. It increases the frequency of extreme events like hurricanes
C. It reduces rainfall globally
D. It stabilizes ocean currents
Answer: B
Explanation: Rising temperatures disrupt weather systems, leading to more frequent and intense extreme weather events, such as storms and droughts, due to changes in atmospheric circulation.
8. Question: What is a key strategy for mitigating global warming?
Options:
A. Increasing deforestation
B. Transitioning to renewable energy sources
C. Expanding urban sprawl
D. Burning more coal
Answer: B
Explanation: Switching to renewable energy sources like solar and wind reduces greenhouse gas emissions, helping to mitigate global warming by lowering reliance on fossil fuels.
9. Question: Which ocean process is worsened by global warming?
Options:
A. Ocean alkalization
B. Ocean acidification
C. Increased fish populations
D. Slower currents
Answer: B
Explanation: Global warming increases CO2 absorption by oceans, leading to acidification, which harms marine life like coral reefs and shellfish by disrupting their ability to form shells.
10. Question: How does global warming impact biodiversity?
Options:
A. It increases habitat availability
B. It causes species extinction due to habitat loss
C. It promotes invasive species everywhere
D. It stabilizes ecosystems
Answer: B
Explanation: Rising temperatures and changing climates destroy habitats, leading to species extinction as plants and animals struggle to adapt or migrate quickly enough.
11. Question: What is the carbon footprint?
Options:
A. The amount of carbon in soil
B. The total greenhouse gas emissions from an activity or entity
C. The size of forests absorbing CO2
D. The weight of fossil fuels used
Answer: B
Explanation: The carbon footprint measures the total amount of greenhouse gases produced by an individual, organization, or product, contributing to global warming.
12. Question: Which factor exacerbates global warming through a feedback loop?
Options:
A. More ice reflection
B. Melting permafrost releasing methane
C. Increased vegetation growth
D. Ocean cooling
Answer: B
Explanation: Melting permafrost releases trapped methane, a potent greenhouse gas, which further warms the planet, creating a feedback loop that accelerates global warming.
13. Question: What is an adaptation measure for global warming?
Options:
A. Building sea walls to protect coasts
B. Increasing emissions
C. Deforesting areas
D. Ignoring climate data
Answer: A
