Abstract

Changes in the moment of inertia of the earth, brought about by the redistribution of ocean water from the tropics to ice at high latitudes, couple energy from the spin of the earth into convection in the liquid core. This mechanism may help provide the driving energy for the earth's dynamo. Sufficiently rapid ocean level changes can disrupt the dynamo, resulting (in half of the cases) in a geomagnetic field reversal. The model can account for the previously mysterious correlation reported between geomagnetic reversals and mass extinctions.

Rise of global mean sea level as an indication of climate change

Journal Article Etkins, R ; Epstein, E S - Science (Washington, D.C.); (United States)

Rising mean sea level, it is proposed, is a significant indicator of global climate change. The principal factors that can have contributed to the observed increases of global mean sea level in recent decades are thermal expansion of the oceans and the discharge of polar ice sheets. Calculations indicate that thermal expansion cannot be the sole factor responsible for the observed rise in sea level over the last 40 years; significant discharges of polar ice must also be occurring. Global warming, due in some degree presumably to increasing atmospheric carbon dioxide, has been opposed by the extraction of heat necessarymore »« less

Climate controls on high sea surface temperatures

Journal Article Waliser, D E - World Resource Review

The ocean`s immense thermal inertia imparts a significant mediating effect on the Earth`s weather and climate. This suggests that the authors ability to predict surface temperature changes over land under a scenario of climate change will only come from an understanding of the climate controls on the surface temperatures over the oceans. In addition, research over the last decade or more has shown that the seasonal, interannual and long-term natural climate fluctuations in the equatorial and mid-latitude regions are particularly sensitive to the sea surface temperature distribution in the warm tropical oceans. In response to these implications, a significant amountmore »« less
Modeling Abrupt Change in Global Sea Level Arising from Ocean - Ice-Sheet Interaction

Other Holland, David M

It is proposed to develop, validate, and apply a coupled ocean ice-sheet model to simulate possible, abrupt future change in global sea level. This research is to be carried out collaboratively between an academic institute and a Department of Energy Laboratory (DOE), namely, the PI and a graduate student at New York University (NYU) and climate model researchers at the Los Alamos National Laboratory (LANL). The NYU contribution is mainly in the area of incorporating new physical processes into the model, while the LANL efforts are focused on improved numerics and overall model development. NYU and LANL will work togethermore »« less

An eddy-permitting ocean-sea ice general circulation model (E3SMv0-HiLAT03): Description and evaluation

Technical Report Zhang, Jiaxu ; Weijer, Wilbert ; Maltrud, Mathew Einar ; ...

We document modeling setups and present results for simulated ocean and sea ice climate from a recently developed, intermediate-resolution global ocean-sea ice model [Energy Exascale Earth System Model version 0 configured for High-Latitude Application and Testing at 0.3° resolution (E3SMv0-HiLAT03)]. The horizontal resolution of HiLAT03 ranges from 33 km in the tropics to 8.5 km at high latitudes, with 100 vertical levels. This resolution allows the explicit representation of some mesoscale eddies, particularly at lower latitudes, therefore being named as an “eddy-permitting model”. Analyses are presented based on the output of two 186-yr control simulations forced by modern atmospheric conditionsmore »« less

The spatial extent and dynamics of the Antarctic Cold Reversal

Journal Article Pedro, Joel B. ; Bostock, Helen C. ; Bitz, Cecilia M. ; ... - Nature Geoscience

Antarctic ice cores show that a millennial-scale cooling event, the Antarctic Cold Reversal (14,700 to 13,000 years ago), interrupted the last deglaciation1,2,3. The Antarctic Cold Reversal coincides with the Bølling–Allerød warm stage in the North Atlantic, providing an example of the inter-hemispheric coupling of abrupt climate change generally referred to as the bipolar seesaw4,5,6,7,8,9. However, the ocean–atmosphere dynamics governing this coupling are debated10,11,12,13,14,15. Here we examine the extent and expression of the Antarctic Cold Reversal in the Southern Hemisphere using a synthesis of 84 palaeoclimate records. We find that the cooling is strongest in the South Atlantic and all regionsmore »« less
