Journal ArticleDOI
Holocene climatic instability: A prominent, widespread event 8200 yr ago
Richard B. Alley,Paul Andrew Mayewski,Todd Sowers,Minze Stuiver,Kendrick C. Taylor,Peter U. Clark +5 more
TL;DR: The most prominent Holocene climatic event in Greenland ice-core proxies, with approximately half the amplitude of the Younger Dryas, occurred ∼8000 to 8400 yr ago.
Journal ArticleDOI
A 25,000-Year Tropical Climate History from Bolivian Ice Cores
Lonnie G. Thompson,Mary E. Davis,Ellen Mosley-Thompson,Todd Sowers,Keith Henderson,V. Zagorodnov,P.-N. Lin,Vladimir Mikhalenko,R. K. Campen,J. F. Bolzan,Jihong Cole-Dai,Bernard Francou +11 more
TL;DR: The abrupt onset and termination of a Younger Dryas-type event suggest atmospheric processes as the probable drivers of regional accumulation during the LGS, during deglaciation, and over the past 3000 years, which is concurrent with higher water levels in regional paleolakes.
Journal ArticleDOI
Temperature dependence of metabolic rates for microbial growth, maintenance, and survival.
P. Buford Price,Todd Sowers +1 more
TL;DR: The rate micros(T) for repairing molecular damage by means of DNA- repair enzymes and protein-repair enzymes such as methyltransferase is found to be comparable to the rate of spontaneous molecular damage, which supports the view that, far below the freezing point, liquid water inside ice and permafrost is available for metabolism.
Journal ArticleDOI
Timing of abrupt climate change at the end of the Younger Dryas interval from thermally fractionated gases in polar ice
TL;DR: In this article, the authors demonstrate that rapid temperature change fractionates gas isotopes in unconsolidated snow, producing a signal that is preserved in trapped air bubbles as the snow forms ice.
Journal ArticleDOI
Extending the Vostok ice-core record of palaeoclimate to the penultimate glacial period
Jean Jouzel,Jean Jouzel,Nartsiss I. Barkov,J. M. Barnola,Michael L. Bender,Michael L. Bender,Jérôme Chappellaz,Christophe Genthon,V. M. Kotlyakov,Vladimir Ya. Lipenkov,C. Lorius,J. R. Petit,J. R. Petit,Dominique Raynaud,Grant M. Raisbeck,Catherine Ritz,Todd Sowers,Michel Stievenard,Françoise Yiou,Pascal Yiou +19 more
TL;DR: The ice-core record of local temperature, dust accumulation and air composition at Vostok station, Antarctica, now extends back to the penultimate glacial period (∼140-200 kyr ago) and the end of the preceding interglacial as discussed by the authors.
