A simple carbon-cycle box model allows for very simple quantitative insight into the evolution of climate over the next millennium. While melting ice sheets, rising sea levels, and ocean acidification are well recognised, we show that a further consequence of the repartitioning of ocean carbon is a dramatic rise in atmospheric carbon dioxide on a millennial time scale.

    The East Antarctic ice sheet is likely more stable than its West Antarctic counterpart because its bed is largely lying above sea level. However, the ice sheet in Dronning Maud Land, East Antarctica, contains marine sectors that are in contact with the ocean through overdeepened marine basins...

    Atmospheric CO2 levels during interglacials prior to the Mid Bruhnes Event (MBE, ~ 430 ka BP) have lower values of around 40 ppm than after the MBE. The reasons for this difference remain unclear. A recent hypothesis proposed that changes in oceanic circulation, in response to differences in...

    The article discusses a study by R.M. DeConto and colleagues on the impact of glaciation on the concentration of carbon dioxide in the atmosphere. The researchers used numerical modeling to constrain the timing of the initiation of glaciation in relation to decreasing levels of carbon dioxide....

    One hundred thousand years of ice sheet buildup came to a rapid end ~25-10 thousand years before present (ka BP), when ice sheets receded quickly and multi-proxy reconstructed global mean surface temperatures rose by ~3-5 °C. It still remains unresolved whether insolation changes due to...

    The article discusses a climatology model that suggests prehistoric sea level rise was not the result of the melting of the East Antarctic ice sheet, as previously thought. Topics include the results of a study appearing in a 2012 issue of the journal "Nature" by Maureen Raymo of Columbia...

    The largest uncertainty in projections of future sea-level change results from the potentially changing dynamical ice discharge from Antarctica. Basal ice-shelf melting induced by a warming ocean has been identified as a major cause for additional ice flow across the grounding line. Here we...

    The article presents a study on the assessment of a parametric uncertainty model in projections of ice sheet behavior in Greenland. It mentions that its computer models offer one of several ways to estimate future sea level rise in response to mass loss from ice sheets. It also notes the...

    Calcification by coral reef communities is estimated to account for half of all carbonate produced in shallow water environments and more than 25% of the total carbonate buried in marine sediments globally. Production of calcium carbonate by coral reefs is therefore an important component of the...
