Climate Change Quiz
Questions: 16 · 10 minutes
1. Which statement accurately compares climate mitigation and climate adaptation?
Mitigation addresses local weather, while adaptation addresses global weather.
Mitigation is carried out only by governments, while adaptation is only personal.
Mitigation limits climate change; adaptation reduces vulnerability to its effects.
Mitigation begins after impacts occur, while adaptation must happen beforehand.
2. A coastal community restores wetlands between developed land and the sea. How can this support climate resilience?
Wetlands can absorb wave energy and floodwater while also storing carbon.
Wetlands permanently stop tropical storms from reaching land.
Wetlands prevent all future sea-level rise near the community.
Wetlands cause seawater to evaporate before it reaches buildings.
3. Which policy most directly puts a financial cost on releasing greenhouse gases?
A building code requiring stronger flood protection
A ban on construction within an erosion zone
A grant for monitoring endangered species
A carbon tax based on the amount of emissions produced
4. Scientists observe warming oceans, retreating glaciers, rising sea levels, and shifting seasonal patterns. Why is this combination especially informative?
Only glacier retreat is relevant because oceans respond too slowly.
Each indicator must have exactly the same local cause.
Multiple independent indicators point toward a broadly warming climate system.
The indicators show that climate varies naturally but cannot reveal a trend.
5. Which statement best describes the main cause of the rapid global warming observed since the mid-20th century?
The natural greenhouse effect began only after industrialization.
Natural changes in the Sun have supplied substantially more energy to Earth.
Human activities have increased heat-trapping gases, mainly through fossil fuel use and land-use change.
Heat released directly by cities and machines has warmed the entire planet.
6. A commuter wants to reduce greenhouse gas emissions from regular trips where practical. Which change is most directly aligned with that goal?
Driving the same distance at a different time of day
Using public transit, cycling, or walking for suitable journeys
Taking a longer route that avoids congested streets
Replacing an older gasoline car with a larger, newer gasoline car
7. A forest is cleared and burned for a new land use. Why can this contribute to climate change?
Stored carbon can be released, and fewer trees remain to take up carbon dioxide.
Removing trees matters only if the land is later paved.
The change affects rainfall but not atmospheric greenhouse gases.
Only the smoke blocks sunlight, creating permanent global cooling.
8. Why does carbon dioxide affect climate even though it makes up a small fraction of the atmosphere?
It is the most abundant gas in the atmosphere.
It produces heat whenever it mixes with oxygen.
It blocks nearly all sunlight before it reaches the surface.
It absorbs infrared radiation at wavelengths relevant to Earth's heat loss.
9. After an unusually cold day, someone says global warming cannot be happening. What is the strongest response?
Cold days no longer occur when the global climate is warming.
Only summer temperatures are relevant to climate trends.
A cold day proves that global temperature records are unreliable.
One local weather event does not overturn a long-term global temperature trend.
10. An office improves insulation, seals air leaks, and installs efficient heating and cooling equipment. What is the most likely climate-related benefit?
The building will no longer require any energy during extreme weather.
The improvements will remove greenhouse gases directly from outdoor air.
Lower energy demand can reduce associated greenhouse gas emissions.
The building will generate renewable electricity from its insulation.
11. What is the clearest distinction between weather and climate?
Weather occurs locally, whereas climate occurs only at the global level.
Weather describes short-term atmospheric conditions; climate describes longer-term patterns and averages.
Weather can be measured directly, whereas climate cannot be measured.
Weather concerns temperature, whereas climate concerns precipitation.
12. Sea ice floating in the ocean melts. Which consequence most directly amplifies warming?
The darker ocean absorbs more solar energy than reflective ice did.
The ocean stops absorbing carbon dioxide once ice disappears.
The melted ice immediately raises sea level by its full former volume.
The exposed ocean releases enough geothermal heat to warm the atmosphere.
13. What is the greenhouse effect?
Certain atmospheric gases absorb and re-emit some infrared energy leaving Earth's surface.
Clouds reflect all outgoing heat back toward Earth's surface.
The ozone layer traps visible sunlight in the lower atmosphere.
Air pollution creates a permanent warm layer around cities.
14. A landfill captures methane and uses it to generate energy instead of releasing it directly. Why can this help limit warming?
Burning methane creates no greenhouse gas emissions under any circumstances.
Methane damages only the ozone layer and has no influence on temperature.
Captured methane removes carbon dioxide already present in the atmosphere.
Methane is a potent greenhouse gas, so preventing its direct release can reduce its warming effect.
15. Two regions use the same amount of electricity. Region A relies mostly on coal, while Region B relies mostly on wind and solar power. What is the best inference?
Their operational greenhouse gas emissions must be identical because electricity use is equal.
Region B will generally have lower greenhouse gas emissions from electricity generation.
Region A has lower emissions because coal plants require less land.
Region B must use less electricity because renewable sources cannot supply the same amount.
16. A city is experiencing more frequent heat waves. Which action is primarily an example of climate adaptation?
Replacing a coal-fired power station with wind turbines
Opening cooling centers and expanding shade in the hottest neighborhoods
Setting a national target for lower carbon dioxide emissions
Subsidizing electric vehicles to reduce future emissions
