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.
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.

TL;DR: In this paper, the North Greenland Eemian Ice Drilling (NEEM) ice core was extracted from folded Greenland ice using globally homogeneous parameters known from dated Greenland and Antarctic ice-core records.
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.

Centennial-scale changes in the global carbon cycle during the last deglaciation

TL;DR: CO2 and methane records of the last deglaciation from a new high-accumulation West Antarctic ice core are presented with unprecedented temporal resolution and precise chronology and suggest that processes operating on centennial timescales seem to be influencing global carbon-cycle dynamics and are at present not widely considered in Earth system models.
