Climate Change 2021—The Physical Science Basis
The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body responsible for assessing the science related to climate change. The Sixth Report from IPCC Working Group 1 publishedExpand
Holocene climatic instability: A prominent, widespread event 8200 yr ago
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. This Holocene event affectedExpand
The 8k event: cause and consequences of a major Holocene abrupt climate change
Abstract A prominent, abrupt climate event about 8200 years ago brought generally cold and dry conditions to broad northern-hemisphere regions especially in wintertime, in response to a very largeExpand
Observations: Changes in Snow, Ice and Frozen Ground

The Younger Dryas cold interval as viewed from central Greenland
Abstract Greenland ice-core records provide an exceptionally clear picture of many aspects of abrupt climate changes, and particularly of those associated with the Younger Dryas event, as reviewedExpand
Abrupt increase in Greenland snow accumulation at the end of the Younger Dryas event
THE warming at the end of the last glaciation was characterized by a series of abrupt returns to glacial climate, the best-known of which is the Younger Dryas event1. Despite much study of the causesExpand
Timing of abrupt climate change at the end of the Younger Dryas interval from thermally fractionated gases in polar ice
Rapid temperature change fractionates gas isotopes in unconsolidated snow, producing a signal that is preserved in trapped air bubbles as the snow forms ice. The fractionation of nitrogen and argonExpand
The Greenland Ice Sheet Project 2 depth-age scale : Methods and results
The Greenland Ice Sheet Project 2 (GISP2) depth-age scale is presented based on a multiparameter continuous count approach, to a depth of 2800 m, using a systematic combination of parameters thatExpand
The role of seasonality in abrupt climate change
Abstract A case is made that seasonality switches dominated by wintertime were instrumental in abrupt climate changes in the North Atlantic region during the last glaciation and into the Holocene.Expand
Flow-law hypotheses for ice-sheet modeling
Ice-flow modeling requires a flow law relating strain rates to stresses in situ, but a flow law cannot be measured directly in ice sheets. Microscopic processes such as dislocation glide and boundaryExpand
