Summary: | <p>Palaeoclimate records display a continuous background of
variability connecting centennial to 100 kyr periods. Hence, the dynamics at
the centennial, millennial, and astronomical timescales should not be
treated separately. Here, we show that the nonlinear character of ice sheet
dynamics, which was derived naturally from the ice-flow conservation laws,
provides the scaling constraints to explain the structure of the observed
spectrum of variability.</p> |
