A
The potential for intense precipitation can increase.
B
Every region will receive more annual precipitation.

Which statement best describes the central idea of climate justice?

A
Climate justice requires every person and country to have identical emissions and identical impacts.
B
Climate justice considers unequal responsibility, unequal impacts, participation, and fair distribution of costs and benefits.
C
Climate justice means climate policies should focus only on total global emissions.
D
Climate justice requires that every location experience the same climate effects.

Which statement best explains why reflective aerosols do not eliminate long-term warming caused by increasing greenhouse-gas concentrations?

A
Aerosols permanently remove greenhouse gases from the atmosphere.
B
Aerosols can temporarily offset some warming but do not eliminate long-term greenhouse-gas warming.
C
Aerosols increase the amount of infrared energy escaping because they absorb all greenhouse gases.
D
Aerosols prevent the oceans from absorbing excess heat.

A region warms after an increase in carbon dioxide. Which change best illustrates a water-vapor feedback?

A
Water vapor reflects all incoming sunlight and therefore always cools the surface.
B
Water vapor is not affected by temperature, so its concentration remains constant.
C
Warming can increase atmospheric water vapor, which can produce additional warming.
D
Warming converts water vapor into carbon dioxide, which is the only greenhouse gas.

Which scenario best demonstrates why climate change can increase both flood risk and water scarcity in the same region?

A
A place can experience both greater flood risk and water scarcity if precipitation becomes more intense and less reliably stored.
B
Any increase in annual precipitation guarantees greater water availability throughout the year.
C
Reduced snowpack always decreases flooding and increases groundwater recharge.
D
Climate change affects only surface water, not evaporation, soil moisture, or groundwater.

Which example is a climate-related phenological mismatch?

A
Birds move to a higher latitude while the insects remain at the same latitude.
B
Birds and insects both shift their seasonal timing by exactly the same amount.
C
Birds increase their population because warmer temperatures provide more food.
D
Insects reach peak abundance before migrating birds arrive to feed their young.

D
Developing a drought-response plan for farms.
