Which gas is the largest contributor to the enhanced greenhouse effect caused by human activities?
Methane (CH?)
Carbon dioxide (CO?)
Nitrous oxide (N?O)
Ozone (O?)
Carbon dioxide is the primary greenhouse gas emitted through human activities such as fossil fuel combustion and deforestation, driving most of the recent warming trend. Its long atmospheric lifetime means it continues to affect climate for centuries. Methane and nitrous oxide are also significant but occur in smaller quantities. Learn more.
Approximately what is the current concentration of carbon dioxide in the atmosphere as of recent measurements?
350 parts per million
415 parts per million
500 parts per million
280 parts per million
Atmospheric CO? levels have risen from about 280 ppm before the Industrial Revolution to over 415 ppm today, according to the NOAA's global monitoring laboratory. This increase is primarily driven by fossil fuel burning and land-use changes. Rising CO? is directly linked to global temperature increases. NOAA data.
Which of the following gases has a global warming potential many times greater than carbon dioxide over a 100-year period?
Argon (Ar)
Methane (CH?)
Oxygen (O?)
Nitrogen (N?)
Methane has a global warming potential around 28 - 36 times greater than CO? over a 100-year period, even though it remains in the atmosphere for a shorter time. It is released by sources like natural gas systems, landfills, and livestock. Reducing methane emissions is a fast way to slow warming. EPA greenhouse gases overview.
Which renewable energy technology converts kinetic energy from wind into electricity?
Hydroelectric dams
Solar panels
Wind turbines
Geothermal plants
Wind turbines capture the wind's kinetic energy through rotating blades, which spin a generator to produce electricity. They are one of the fastest-growing sources of renewable energy globally. Unlike solar panels, they operate day and night as long as wind is available. DOE on wind energy.
What does the term "radiative forcing" refer to in climate science?
The balance between incoming solar and outgoing infrared radiation
The amount of greenhouse gases in the stratosphere
The concentration of aerosols in the troposphere
The rate of sea-level rise per decade
Radiative forcing measures the change in energy flux at the top of the atmosphere due to factors like greenhouse gas increases or aerosol changes. Positive forcing warms the climate, while negative forcing cools it. It is a key metric in IPCC assessments. IPCC AR4 explanation.
Which feedback mechanism accelerates warming by decreasing Earth's reflectivity as ice and snow melt?
Carbon uptake feedback
Ice - albedo feedback
Cloud feedback
Water vapor feedback
Ice - albedo feedback occurs when warming causes ice and snow to melt, reducing the surface's reflectivity and absorbing more solar energy, which leads to further warming. This cycle is especially strong in polar regions. It is a key positive feedback in climate models. NASA on ice - albedo.
Ocean acidification is primarily caused by which process?
Absorption of atmospheric CO?
Plastic pollution
Increased ocean warming
Oil spills
When CO? dissolves in seawater, it forms carbonic acid, lowering ocean pH and reducing carbonate ion concentrations. This acidification harms calcifying organisms like corals and shellfish. It is an ongoing impact of anthropogenic CO? emissions. NOAA Ocean Acidification.
Which economic sector currently contributes the most to global greenhouse gas emissions?
Agriculture, forestry, and land use
Electricity and heat production
Transportation
Industrial processes
Electricity and heat production, largely from coal and natural gas, accounts for about one-quarter of global emissions, making it the largest single sector. Shifting to renewables and improving efficiency are critical mitigation strategies. Other sectors like agriculture and transport also play significant roles. IEA emissions data.
By approximately how much has the global average surface temperature risen since pre-industrial times (1850 - 1900)?
About 0.5°C
About 1.1°C
About 3.5°C
About 2.0°C
Global surface temperatures have increased by about 1.1°C relative to the 1850 - 1900 baseline, according to the IPCC Sixth Assessment Report. This warming is unprecedented in at least the last two millennia. Continual CO? emissions could push warming beyond 1.5°C soon. IPCC AR6 Summary.
In IPCC terminology, which Representative Concentration Pathway (RCP) corresponds to a high-emission scenario with roughly 8.5 W/m² of radiative forcing by 2100?
RCP4.5
RCP6.0
RCP8.5
RCP2.6
RCP8.5 represents a high-greenhouse-gas-emission scenario leading to about 8.5 W/m² of radiative forcing by 2100. It is often used as a worst-case pathway in impact studies. Lower RCPs like 2.6 and 4.5 assume stronger mitigation. IIASA on RCPs.
What does "equilibrium climate sensitivity" measure?
Short-term weather variability
Sea-level change per degree of warming
The long-term temperature increase after CO? doubling
Annual fluctuation in solar output
Equilibrium climate sensitivity estimates the steady-state global temperature increase following a doubling of atmospheric CO? concentration. It incorporates slow feedbacks like ice sheet changes and water vapor feedback. Estimates typically range between 1.5°C and 4.5°C. IPCC SR15.
Which landmark international agreement has the goal of limiting global temperature rise to well below 2°C above pre-industrial levels?
Kyoto Protocol
Montreal Protocol
Paris Agreement
Rio Declaration
The Paris Agreement, adopted in 2015, aims to limit warming to well below 2°C, with efforts to cap it at 1.5°C. It relies on Nationally Determined Contributions from each country. Unlike the Kyoto Protocol, it includes both developed and developing nations. UNFCCC on Paris.
What is meant by the term "carbon budget" in climate policy discussions?
The yearly target for renewable energy investment
The amount of CO? that oceans can absorb annually
The maximum cumulative CO? emissions to stay below a temperature threshold
The economic cost limit for carbon trading
A carbon budget defines the total amount of CO? that can be emitted while keeping warming below a specified temperature threshold, such as 1.5°C. It is calculated based on climate sensitivity and remaining allowable emissions. Policymakers use it to set emission reduction targets. IPCC SR15 Chapter 2.
