The plio-pleistocene 405-kyr climate cycles
Webb19 aug. 2014 · Lectures on YouTube. Environmental hypotheses of African faunal evolution propose that major faunal speciation, extinction, and innovation events during the Pliocene-Pleistocene were mediated by changes in African climate or shifts in climate variability. Marine and terrestrial sediment sequences demonstrate that subtropical African climate ... Webbbeen linked to glacial–interglacial climate cycles. It is gener-ally thought that the 100,000-yr glacial cycles of the past 800,000 yr are a result of orbital eccentricity1–4. ... because the internal climate feedbacks responsible for Plio-Pleistocene 100-kyr cycles are inhibited by strong precession forcing.
