1 sie 2013 · Interglacial SST trends from the high northern and mid-southern latitudes (Sites 982, 1123, 1090; R < 0.4) show no discernible long-term change across the Pleistocene whereas SST trends from the mid-northern latitudes (Sites 607, 1020) show a slight cooling (R > 0.4; Table 3; Fig. 4 b).
16 lut 2024 · Interglacial cycles initially lasted roughly 41 000 years. Then around 1 million years ago, they slowed to a length of around 100 000 years. This surprising shift in glacial-interglacial pacing is known as the Mid-Pleistocene Transition. Its origin is a mystery.
1 sie 2024 · During the Mid-Pleistocene Transition, between ~1.2 million and 700 thousand years ago, the length of Earth’s glacial cycles changed from ~41,000 years to ~100,000 years, but the reason for this shift is not clear.
Pleistocene Epoch, earlier and major of the two epochs of the Quaternary Period of Earth’s history, an epoch during which a succession of glacial and interglacial climatic cycles occurred. It ended 11,700 years ago. It was preceded by the Pliocene Epoch and followed by the Holocene Epoch.
3 kwi 2019 · The long-term CO 2 decrease leads to the initiation of Northern Hemisphere glaciation and an increase in the amplitude of glacial-interglacial variations, while the combined effect of CO 2 decline and regolith removal controls the timing of the transition from a 41,000- to 100,000-year world.
1 wrz 2024 · We hypothesize that cumulative insolation perturbations have disrupted the heat balance within Earth's climate system, contributing to the Pleistocene long-term climate change. The early Pleistocene long-term cooling, as indicated by the GSSTA, implies a reduction in heat within the climate system.
21 wrz 2016 · Abstract. On the basis of fossil and archaeological data it has been hypothesized that the exodus of Homo sapiens out of Africa and into Eurasia between ~50–120 thousand years ago occurred...
