These records may suggest an expansion to the north and northeast following the Pleistocene Epoch. Fossil records have documented sage-grouse during the late Pleistocene (13,000-18,000 BP) well south of their current range (Howard and Miller, 1933; Harris 1989; Brasso and Emslie, 2006).

While we are technically still within the ice age that began 2.6 million years ago at the start of the Pleistocene epoch because the Greenland, Arctic and Antarctic ice sheets still exist, the current global warming situation can dramatically and quickly reduce those ice sheets and cause significant changes in the Earth's magnetic field.
Climate-wise, the Earth had begun a drying and cooling trend, culminating in the glaciations of the Pleistocene Epoch, and partially offset by the Paleocene-Eocene Thermal Maximum.
