Question 1

Why is the anthropogenic enhancement of the greenhouse effect radiatively more consequential than the extra heat released directly by fossil-fuel combustion?

Fossil-fuel combustion adds greenhouse gases that trap outgoing longwave radiation continuously for decades to centuries, so each tonne of CO₂ multiplies radiative forcing far beyond the one-time heat of burning Burning fossil fuels cools the atmosphere, so only greenhouse gases can warm it Direct combustion heat is the sole climate driver; greenhouse gases play no role CO₂ reflects sunlight back to space more strongly than combustion heat warms the air

Correct Answer:

Question 2

In an eA analysis of Earth's radiation budget, what happens to outgoing longwave radiation when global surface temperature rises under fixed greenhouse-gas concentrations?

Outgoing longwave emission increases roughly with the fourth power of temperature (Stefan–Boltzmann), providing a negative feedback that tends to restore energy balance Outgoing longwave radiation permanently falls to zero once temperature rises Outgoing longwave radiation becomes independent of temperature Only albedo can change; longwave emission is fixed by solar constant alone

Correct Answer:

Outgoing longwave emission increases roughly with the fourth power of temperature (Stefan–Boltzmann), providing a negative feedback that tends to restore energy balance

Question 3

How does the water-vapour feedback amplify anthropogenic warming?

A warmer atmosphere holds more water vapour (Clausius–Clapeyron); because water vapour is itself a greenhouse gas, the initial CO₂-driven warming is reinforced Water vapour destroys all CO₂, so humidity cools the planet Increased humidity always increases albedo enough to cancel any greenhouse warming Water vapour only affects weather, never the planetary radiation budget

Correct Answer:

A warmer atmosphere holds more water vapour (Clausius–Clapeyron); because water vapour is itself a greenhouse gas, the initial CO₂-driven warming is reinforced

Question 4

Which statement best captures the ice–albedo feedback as a climate amplifier?

Warming melts ice and snow, lowering surface albedo so more shortwave radiation is absorbed, which further warms the surface and accelerates melt Melting ice always increases albedo because open water is brighter than ice Ice melt only affects sea level; it has no radiative feedback Albedo feedback operates only on Venus, not Earth

Correct Answer:

Warming melts ice and snow, lowering surface albedo so more shortwave radiation is absorbed, which further warms the surface and accelerates melt

Question 5

ENSO (El Niño–Southern Oscillation) is a key teleconnection. What defines an El Niño phase in the tropical Pacific?

Anomalously warm eastern/central equatorial Pacific sea-surface temperatures with weakened trade winds and a shift of convection eastward, altering rainfall and circulation patterns globally Permanent cooling of the entire Atlantic Ocean only Strengthening of the northeast trades that cools the eastern Pacific below normal A purely stratospheric ozone anomaly with no ocean involvement

Correct Answer:

Anomalously warm eastern/central equatorial Pacific sea-surface temperatures with weakened trade winds and a shift of convection eastward, altering rainfall and circulation patterns globally
