Earth’s orbit affects millennial climate variability

There is ample geological evidence to show that Earth’s climate experienced millennial-scale variability superimposed on glacial-interglacial fluctuations during the Pleistocene. The magnitude of millennial climate variability has been linked to glacial cycles over the past 800 thousand years (kyr). For the period leading up to the mid-Pleistocene transition, when global glaciations were less severe but […]
