Climate Change Environmental Science Fundamentals 5

Question 1

What is the difference between weather and climate in scientific terms?

Accepted Answer

Weather describes short-term atmospheric conditions; climate is the long-term average pattern over decades

Answer

Weather refers to global patterns; climate refers to local daily conditions

Answer

Weather is measured by satellites; climate is measured by ground stations

Answer

Weather applies only to the troposphere; climate includes all atmospheric layers

Question 2

How does the 'social cost of carbon' inform climate policy decisions?

Accepted Answer

It quantifies the economic damages caused by emitting one additional ton of CO₂

Answer

It measures the total cost of building renewable energy infrastructure

Answer

It calculates the market price of carbon credits in emissions trading systems

Answer

It estimates the cost of transitioning workers from fossil fuel industries

Question 3

What is 'carbon capture and storage' (CCS) and what is its primary limitation at scale?

Accepted Answer

Capturing CO₂ at emission sources and injecting it underground; limited by high costs and storage capacity uncertainty

Answer

Planting forests to absorb CO₂; limited by available land

Answer

Removing CO₂ from the atmosphere using chemical scrubbers; limited by energy requirements

Answer

Storing carbon in agricultural soils through no-till farming; limited by measurement difficulties

Question 4

Which feedback mechanism involves increased water vapor amplifying warming caused by CO₂?

Accepted Answer

Water vapor feedback

Answer

Ice-albedo feedback

Answer

Cloud radiative feedback

Answer

Lapse rate feedback

Question 5

What is 'environmental justice' in the context of climate change impacts in the United States?

Accepted Answer

The principle that low-income and minority communities bear disproportionate climate burdens and deserve equal protection

Answer

Legal action taken against companies that violate EPA emissions standards

Answer

International agreements ensuring equal emission reduction commitments from all countries

Answer

The right of future generations to a stable climate under current US law

Question 6

What does 'parts per million (ppm)' measure in the context of atmospheric CO₂ monitoring?

Accepted Answer

The number of CO₂ molecules per million total air molecules

Answer

The percentage of Earth's surface covered by CO₂-absorbing vegetation

Answer

The mass of CO₂ in millions of metric tons per year

Answer

The concentration of CO₂ per million liters of ocean water

Question 7

Which international agreement set legally binding emission reduction targets for developed nations for the first time?

Accepted Answer

The Kyoto Protocol (1997)

Answer

The Paris Agreement (2015)

Answer

The Montreal Protocol (1987)

Answer

The Rio Earth Summit Declaration (1992)
