Earth’s orbit affects millennial climate variability

Abundant geological evidence demonstrates that Earth’s climate has experienced millennial-scale variability superimposed on glacial-interglacial fluctuations through the Pleistocene. The magnitude of millennial climate variability has been linked to glacial cycles over the past 800 thousand years (kyr). For the period before the Mid-Pleistocene Transition, when global glaciations were less pronounced but more frequent, scientists had been […]
