Ice-Albedo Feedback Bifurcation
Budyko-Sellers EBM:
C·dT/dt = Q·(1-α(T)) - A - BT
α(T) = α_ice if T < T_ice
α_ocean if T > T_melt
Snowball Earth: global bifurcation
Hysteresis: unstable middle branch
Solar constant Q (W/m²):
342
Outgoing LW: A+BT (A):
202
α_ice (ice albedo):
0.62
α_ocean (ocean albedo):
0.10
