The reaction part exhibits a jump discontinuity (at the snow line). Here we introduce a Babuska-Duhem hysteresis in order to account for a frequent repetition of sudden and fast warming followed by much slower cooling as observed from paleoclimate proxy data. Existence of global solutions and of a trajectory attractor will be established for the resulting system of a parabolic differential inclusion and an ode.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0362546X05007352http://www.sciencedirect.com/restricted access517.91equationsEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
