Negative climate forcing occurs when solar radiation is more:

Negative climate forcing occurs when solar radiation is more:

• A. reflected
• B. absorbed
• C. emitted by the surface
• D. generated by geothermal sources

Answer: (A)

Negative climate forcing happens when less energy stays in the planet system because more of the incoming solar radiation is sent back to space. When solar radiation is more reflected, the planet’s albedo increases, so a smaller portion of the Sun’s energy is absorbed by land, ocean, and atmosphere. With less energy absorbed, the overall energy input drops, which tends to cool the climate. Emitting energy from the surface or geothermal heat adds energy to the system and tends to warm it, not cool it, so those options don’t produce negative forcing.
