The pacing of glacial–interglacial cycles during the Quaternary period (the past 2.6 million years) is attributed to astronomically driven changes in high-latitude insolation. However, it has not been ...

Figure 1: Time series of forcing and responses of Northern Hemisphere ice sheets. Figure 2: Hysteresis of equilibrium states and transient evolution of the Northern Hemisphere ice sheets. Figure 3: ...

Science has struggled to explain fully why an ice age occurs every 100,000 years. As researchers now demonstrate based on a computer simulation, not only do variations in insolation play a key role, ...
