The Earth shape, gravity and rotation are highly affected by climatic variations associated with the glacial cycles
in the late Pleistocene.
Climate changes associated with glacial cycles
and diverse topography almost certainly influence the distribution of salamanders (Pielou 1991; Hewitt 2004).
For this purpose, we adopt the ICE-5G global ice model (Peltier, 2004) that encompasses the last full glacial cycle
In recent decades, notes Kerr, a Science staff writer, scientists have come to think that the glacial cycles
were somehow linked to slight variations in the shape (or eccentricity) of the Earth's orbit that occur at about the same 100,000-year intervals.
This part of the study aims at unravelling the mechanism responsible for the observed discrepancies and developing innovative trapped charge dating measurement protocols based on quartz that will yield reliable ages for and beyond the last interglacial glacial cycle

Contrary to the theory of ocean floor stability, the diversity of species rose and fell in sync with the glacial cycle
For ice-sheets, the objectives are to increase our understanding of and ability to model the coupled evolution of ice-sheets and climate on multi-millennial timescales, in particular regarding the last glacial cycle
and the long-term future of the Greenland ice-sheet.
Scientists had thought that decreasing levels of carbon dioxide in the atmosphere caused a major change in Earth's glacial cycle
some time between 1.
Since the late 1800s, scientists have theorized that subtle shifts in Earth's orbit orchestrate the glacial cycle
Former studies found significant re-organisations of ocean dynamics during the last glacial cycle
, but were not able to provide robust, quantitative estimates of past changes in ocean circulation.
Scientists who study the glacial cycle
have traditionally relied on climate records constructed by measuring the oxygen isotopes in seafloor sediments.
They suggest the gas changes amplify slight variations in Earth's orbit, which serve as the pacemaker for the glacial cycle
Though the direct effects of the eruptions have faded from view, climate feedback from ice sheets, wind patterns, and changes in the earth orbit are enough to keep us in the glacial cycle
deep-freeze ice ages that return every 20,000 to 100,000 years.
Computer experiments now suggest the rise of the two great plateaus on either side of the Northern Hemisphere primed the planet for entering the current glacial cycle
, which began 2.
