← GeographyWhich global outcome results when increased aerosol concentrations amplify Earth's albedo effect?
A)Reduced ocean salinity in polar regions
B)Weakened Walker circulation in Pacific
C)Diminished Hadley cell convection strength✓
D)Accelerated permafrost thaw in Siberia
💡 Explanation
When aerosols increase albedo, more solar radiation is reflected, reducing surface heating because less energy is absorbed, weakening the temperature gradient that drives the Hadley cells. Therefore diminished convection strength results, rather than salinity changes, altered Walker circulation, or altered permafrost thaw, each having different drivers.
