← GeographyWhich mechanism amplifies the initial Milankovitch cycle forcing on global temperatures?
A)Isostatic rebound modifying continental tilt
B)Dust deposition altering atmospheric albedo
C)Ice-albedo feedback increasing solar absorption✓
D)Oceanic thermohaline circulation weakening drastically
💡 Explanation
When initial Milankovitch cycles induce slight warming, ice-albedo feedback occurs because melting ice exposes darker surfaces that absorb more solar radiation, amplifying the initial warming. Therefore ice-albedo feedback increases solar absorption, rather than rebound, dust changes, or circulation shifts, each needing independent forcing scenarios.
