East African megadroughts between 135 and 75 thousand years ago and bearing on early-modern human origins
Christopher A. Scholz,Thomas C. Johnson,Andrew S. Cohen,John W. King,John A. Peck,Jonathan T. Overpeck,Michael R. Talbot,Erik T. Brown,L. Kalindekafe,Philip Y.O. Amoako,R. P. Lyons,Timothy M. Shanahan,Isla S. Castañeda,Clifford W. Heil,Steven L. Forman,Lanny R. McHargue,Kristina R.M. Beuning,Jeanette Gomez,James Pierson +18 more
TL;DR: Results from new scientific drill cores from Lake Malawi are presented, the first long and continuous, high-fidelity records of tropical climate change from the continent itself, providing evidence for dramatically wetter conditions after 70 kyr ago.
Journal ArticleDOI
Lake Baikal Record of Continental Climate Response to Orbital Insolation During the Past 5 Million Years
Douglas F. Williams,John A. Peck,Eugene B. Karabanov,Alexander A. Prokopenko,Vadim A. Kravchinsky,John W. King,Mikhail I. Kuzmin +6 more
TL;DR: The sedimentary record of biogenic silica from Lake Baikal in south-central Siberia suggests that this region of central Asia was impacted by two major cooling episodes at 2.8 to 2.6 and 1.6 million years ago.
Journal ArticleDOI
Atlantic Forcing of Persistent Drought in West Africa
Timothy M. Shanahan,Timothy M. Shanahan,Jonathan T. Overpeck,Kevin J. Anchukaitis,J. W. Beck,Julia E. Cole,David L. Dettman,John A. Peck,Christopher A. Scholz,John W. King +9 more
TL;DR: It is found that intervals of severe drought lasting for periods ranging from decades to centuries are characteristic of the monsoon and are linked to natural variations in Atlantic temperatures, indicating that themonsoon is capable of longer and more severe future droughts.
Journal ArticleDOI
The time-transgressive termination of the African Humid Period
Timothy M. Shanahan,Nicholas P. McKay,Konrad A Hughen,Jonathan T. Overpeck,Bette L. Otto-Bliesner,Clifford W. Heil,John W. King,Christopher A. Scholz,John A. Peck +8 more
TL;DR: In this article, the termination of humidity was spatially variable, moving towards progressively lower latitudes in Africa during the early to mid-Holocene, during which Africa was more humid than today.
Journal ArticleDOI
Continental climate response to orbital forcing from biogenic silica records in Lake Baikal
Steven M. Colman,John A. Peck,Eugene B. Karabanov,Susan J. Carter,J.P. Bradbury,John W. King,Douglas F. Williams +6 more
TL;DR: This paper used the record of biogenic silica in Lake Baikal as a proxy for climate change in this high-latitude mid-continental region and found a good correlation between this record and that of marine oxygen isotopes4.
