Ice-sheet initiation and climatic influences of expanded snow cover in Arctic Canada
TLDR
In this article, a large increase in extent of October 1st snow cover in the Canadian Arctic from 1967-1970 to 1971-1975 is compared to changes in other climate variables over the area of snow-cover expansion.About:

Oxygen-isotope analyses and Pleistocene ice volumes
Alan C Mix,William F. Ruddiman +1 more
TL;DR: In this article, a simple numerical model of the isotopic response of the oceans to ice-volume change was developed, and the major features it simulates are (1) the changing mean isotopic composition of snow as a function of ice volume, and (2) selective preservation of isotopically more negative (colder, higher-latitude) ice.

Initiation and development of the Laurentide and Cordilleran Ice Sheets following the last interglaciation
Peter U. Clark,John J. Clague,B. Brandon Curry,Aleksis Dreimanis,Stephen R. Hicock,Gifford H. Miller,Glenn W. Berger,Nicholas Eyles,Michel Lamothe,Banks Miller,Robert J. Mott,R.N. Oldale,R.R. Stea,J.P. Szabo,L. H. Thorleifson,J.-S. Vincent +15 more
TL;DR: Fossil records from sites overridden by or adjacent to the Laurentide Ice Sheet indicate that the climate of the last interglaciation (Oxygen-Isotope Substage 5e, ca. 130-116 ka) was warmer than today.
Journal ArticleDOI
The geologic record of climatic change
TL;DR: In this paper, the authors surveyed the time interval from the formation of the Earth 4.6 billion years ago to the development of the instrumental record and investigated major results from paleoclimatic investigations.
Journal ArticleDOI
Dynamics of the North American Ice Sheet complex during its inception and build-up to the Last Glacial Maximum.
TL;DR: In this article, the authors explore the inception and growth of ice (120-20 ka) using a glacial systems model which has been calibrated against a large and diverse set of data relating to the deglacial interval.
Journal ArticleDOI
Keewatin Ice Sheet—Re-evaluation of the traditional concept of the Laurentide Ice Sheet
TL;DR: The authors showed that the Keewatin Ice Divide and its precursors represent the centers of an independent, land-based ice sheet that probably existed throughout the period of Wisconsin Glaciation.

Variations in the Earth's Orbit: Pacemaker of the Ice Ages
TL;DR: It is concluded that changes in the earth's orbital geometry are the fundamental cause of the succession of Quaternary ice ages and a model of future climate based on the observed orbital-climate relationships, but ignoring anthropogenic effects, predicts that the long-term trend over the next sevem thousand years is toward extensive Northern Hemisphere glaciation.

The Seesaw in Winter Temperatures between Greenland and Northern Europe. Part I: General Description
Harry van Loon,Jeffery C. Rogers +1 more
TL;DR: In this paper, the authors investigated the well-known tendency for winter temperatures to be low over northern Europe when they are high over Greenland and the Canadian Arctic, and conversely, they found that these pressure anomalies are so distributed that the pressure in the region of the Icelandic low is negatively correlated with the pressure over the North Pacific Ocean and over the area south of 50°N in the North Atlantic Ocean, Mediterranean and Middle East.

Insolation changes, ice volumes, and the O18 record in deep‐sea cores
Wallace S. Broecker,Jan van Donk +1 more
TL;DR: In this article, a detailed curve of ice volume versus time is needed in order to test the validity of the hypothesis that changes in the earth's orbital parameters are the cause of oscillations in Pleistocene climate.

Astronomical theory of climatic change: support from new Guinea.
H. Herbert Veeh,John Chappell +1 more
TL;DR: Radiocarbon and thorium-230 dates of uplifted coral reef terraces on New Guinea appear to support theories of glaciation which utilize Milankovitch cycles as a controlling trigger mechanism, suggesting a marine transgression between 50,000 and 35,000 years before the present.
