Which greenhouse gas is released in the greatest volume by burning fossil fuels?
Methane
Carbon dioxide
Nitrous oxide
Water vapor
Carbon dioxide is the main greenhouse gas produced when fossil fuels are burned, making it the largest contributor. Methane and nitrous oxide are also greenhouse gases but are emitted in lower quantities from combustion. Water vapor levels are controlled largely by atmospheric processes rather than direct fossil fuel burning.
Which human activity is the largest source of methane emissions globally?
Rice cultivation
Cement production
Coal mining
Cattle and livestock farming
Livestock, especially cattle, produce methane during digestion (enteric fermentation), making agriculture a major source. Rice paddies, coal mining, and cement production contribute methane but to a lesser extent.
Which practice is the major source of nitrous oxide emissions?
Burning natural gas for heating
Use of synthetic fertilizers in agriculture
Deforestation
Industrial steel production
Synthetic fertilizer application releases nitrous oxide through soil microbial processes. Fossil fuel burning, deforestation, and steel production emit other greenhouse gases but are not the primary nitrous oxide sources.
What term describes the long-term rise in Earth's average surface temperature?
Global warming
Climate variability
Global cooling
Ozone depletion
Global warming refers to the long-term increase in Earth's average surface temperature, driven largely by greenhouse gas emissions. Climate variability describes short-term fluctuations, while ozone depletion and global cooling are unrelated phenomena.
How does planting trees help mitigate climate change?
Trees absorb carbon dioxide through photosynthesis
Trees reflect sunlight to space
Trees emit oxygen which cools the atmosphere
Trees release water vapor to form clouds
Trees sequester carbon dioxide by converting it into biomass during photosynthesis, reducing atmospheric CO2 levels. While they release oxygen, that does not directly cool the atmosphere, and they have limited impact on reflection or cloud formation compared to carbon uptake.
Which sector is responsible for the largest share of global greenhouse gas emissions?
Land use change
Residential buildings
Energy production and use
Waste management
Energy production, including electricity generation and heat, is the largest emitter of greenhouse gases globally. Waste management, buildings, and land use change contribute significantly but at lower levels.
What is 'radiative forcing' in the context of climate change?
The change in net energy at the top of the atmosphere
The amount of solar energy reflected by clouds
The force of wind on the Earth's surface
The rate of greenhouse gas emissions per year
Radiative forcing quantifies the change in net energy flux at the top of the atmosphere caused by factors like greenhouse gas concentrations. It is not a measure of wind force, emission rate, or cloud reflectivity alone.
Ice core records provide evidence of past climates primarily by measuring which of the following?
Surface albedo of the ice sheets
The color of ice layers
Mineral deposits in ice layers
Trapped air bubbles indicating historic CO2 levels
Ice cores contain air bubbles that trap past atmospheres, allowing scientists to measure historic CO2 concentrations. Color, mineral layers, and albedo offer additional information but are not the primary climate proxies in this context.
Which human activity significantly contributes to increased atmospheric methane aside from agriculture?
Automobile exhaust emissions
Cement manufacturing
Landfill decomposition of organic waste
Nuclear power generation
Landfills produce methane as organic waste decomposes anaerobically. Automobiles emit CO2 and other pollutants, cement manufacturing emits CO2, and nuclear power emits negligible greenhouse gases.
How does deforestation primarily increase atmospheric CO2 levels?
Reduces the number of trees that absorb CO2 and releases stored carbon when burned or decomposed
Increases soil reflectivity, trapping heat
Raises methane production in nearby wetlands
Decreases evaporation from plant leaves
Deforestation removes trees that sequester carbon and often involves burning or decay of biomass, releasing CO2. Changes in albedo, methane production, or evapotranspiration are secondary effects.
Which strategy is an example of climate change mitigation?
Improving the energy efficiency of buildings
Developing drought-tolerant crops
Building seawalls to protect coastal cities
Conducting early warning systems for storms
Improving energy efficiency reduces greenhouse gas emissions, directly mitigating climate change. Seawalls and early warning systems are adaptation measures, and drought-tolerant crops adapt to changing conditions.
What is an example of an adaptation measure in agriculture to cope with drought?
Planting drought-resistant crop varieties
Installing carbon capture on tractors
Reducing fertilizer application
Increasing fossil fuel use for irrigation
Drought-resistant varieties help crops survive low-water conditions, making them an agricultural adaptation. Reducing fertilizer or capturing carbon on tractors addresses emissions, not water stress, and increasing fossil fuel use worsens emissions.
How do greenhouse gases warm the Earth's surface?
By increasing the Earth's albedo
By reflecting incoming solar radiation
By blocking visible sunlight
By trapping outgoing infrared radiation
Greenhouse gases allow solar radiation to enter but absorb and re-emit outgoing infrared radiation, warming the atmosphere and surface. They do not reflect sunlight or increase albedo, nor block visible light.
Which observation is direct evidence of ocean acidification?
Rising sea surface temperature
Increasing ocean salinity
Expansion of marine dead zones
Decreasing pH levels in seawater over time
A drop in seawater pH demonstrates increased acidity due to CO2 dissolution. Temperature rise, salinity changes, and dead zones are impacts of climate change but are not direct measures of acidification.
What urban planning practice helps reduce the urban heat island effect?
Increasing green spaces and vegetation cover
Building higher concrete walls
Installing more asphalt pavements
Minimizing tree canopy for airflow
Green spaces cool urban areas through shade and evapotranspiration, mitigating heat islands. Concrete walls and asphalt trap heat, and reducing canopy removes shade, worsening the effect.
Which greenhouse gas has the highest global warming potential (GWP) over a 100-year time horizon?
Methane (CH4)
Carbon dioxide (CO2)
Sulfur hexafluoride (SF6)
Nitrous oxide (N2O)
SF6 has an extremely high GWP (over 23,000 times that of CO2 over 100 years), making it the most potent greenhouse gas listed. CO2, CH4, and N2O have much lower GWPs over the same period.
Which technology combines biomass energy production with CO2 removal from the atmosphere?
Enhanced weathering
Bioenergy with carbon capture and storage (BECCS)
Direct air capture
Solar photovoltaic panels
BECCS involves growing biomass that captures CO2, using it for energy, and then capturing and storing the combustion emissions. Direct air capture removes CO2 directly, photovoltaics generate electricity, and enhanced weathering accelerates natural mineral CO2 uptake.
A country emits 20 GtCO2 annually. If it reduces emissions by 20% through renewable energy and land-use changes add 1 GtCO2, what are its net annual emissions?
19 GtCO2
16 GtCO2
15 GtCO2
17 GtCO2
A 20% reduction of 20 GtCO2 equals 4 GtCO2, so emissions drop to 16 GtCO2; adding 1 GtCO2 from land use brings the net to 17 GtCO2. Calculating reductions then additions yields the net emission.
Which scenario best illustrates a climate 'tipping point'?
Rapid melting of the Greenland ice sheet leading to irreversible sea-level rise
Minor fluctuations in daily temperature extremes
Seasonal shift in monsoon timing that returns to normal
Annual variability in El Niño and La Niña events
A tipping point is a threshold where a small change triggers a large, often irreversible shift, such as the Greenland ice sheet collapse. Seasonal monsoon shifts and interannual variability are part of natural cycles.
Observations show that over the past century, over 90% of the excess heat trapped by greenhouse gases has been absorbed by the oceans. What does this imply about the Earth's climate system?
Ice sheets are the principal heat reservoirs
Most warming occurs in the stratosphere
Oceans act as a major heat sink, delaying surface warming
The land surface temperature rises faster than the ocean
Oceans absorb and store the majority of excess heat, moderating atmospheric temperature increases. Stratospheric warming is limited, ice sheets do not store heat the same way, and land warms faster but holds less heat overall.

Cheat Sheet

  1. Primary Greenhouse Gases - Gases like carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and fluorinated gases act like a thermal blanket around Earth, trapping heat and keeping our planet cozy. They're released by everything from power plants and cars to rice paddies and refrigerators, so it pays to know your CO₂ from your CF₄! EPA: Overview of Greenhouse Gases
  2. Human Impact on CO₂ Levels - Since the Industrial Revolution, we've been burning coal, oil, and gas like there's no tomorrow, sending atmospheric CO₂ skyrocketing. This extra carbon dioxide is a major driver behind rising global temperatures, so understanding our own role is the first step to making a change. UN: Causes & Effects of Climate Change
  3. Data on GHG Trends - Scientists track greenhouse gas concentrations with high-precision instruments, revealing a clear upward trend over the past century. Linking these data points to temperature records shows a tight correlation: more gases, more warming. EIA: Greenhouse Gases & the Climate
  4. Climate Change Indicators - From record-hot summers and melting ice caps to rising sea levels and shifting wildlife patterns, the evidence for a warming world is everywhere. Spotting these indicators helps us see just how fast - and how dramatically - the planet is changing. UN: Causes & Effects of Climate Change
  5. Adaptation Strategies - When floods, droughts, or heatwaves come knocking, smart solutions like green roofs, flood barriers, and drought-resistant crops can save the day. Adaptation isn't just surviving - it's thriving in a world that's warming up. UN: Causes & Effects of Climate Change
  6. Mitigation Strategies - Cutting emissions at the source is the dream: think wind turbines spinning, solar panels soaking up rays, and super-efficient buildings that barely need heating or cooling. These strategies slow down climate change before it speeds out of control. UN: Causes & Effects of Climate Change
  7. Understanding Carbon Footprints - Every time you choose the bus over a car, or swap a beef burger for beans, you shrink your personal carbon footprint. Simple lifestyle tweaks add up to big emission cuts when millions join in! UN: Causes & Effects of Climate Change
  8. International Climate Agreements - The Paris Agreement and its global buddies unite countries around the goal of limiting warming to well below 2°C. By pledging cuts and reporting progress, nations work together to keep our Earth from overheating. UN: Causes & Effects of Climate Change
  9. Deforestation & the Carbon Cycle - Trees are Earth's natural carbon sponges, but when forests are felled, stored CO₂ gets released back into the atmosphere. Protecting and restoring forests is a win-win for biodiversity and climate. UN: Causes & Effects of Climate Change
  10. Scientific Consensus & the IPCC - Thousands of experts review decades of research to produce Intergovernmental Panel on Climate Change (IPCC) reports - our gold standard for understanding climate risks and solutions. When the world's scientists agree, it's time to listen! EIA: Greenhouse Gases & the Climate
