What's more, the group found evidence that the last major glacial period prior to the last ice age, from a time dating to 150,000 years ago, mirrored North American climate for the same period.

During the last glacial period, the climate of the Northern Hemisphere was characterized by rapid, large-amplitude temperature fluctuations through cycles lasting a few thousand years1,2,3.
