Sentences with phrase «ice sheet extent»

Most modelling studies of this period do not treat ice sheet extent and elevation or CO2 concentration prognostically, but specify them as boundary conditions.
Terrestrial glacial geologists (such as ourselves) can gain information of past glacial behaviour from mapping and dating former ice sheet extents, and determining the rates at which they receded and thinned, [e.g., 16, 17 - 19].
The uncertainty in the regions affected by high - end climate change during DJF (the Arctic) is mostly due to differences in modelled temperature increases, which are caused by biases in simulated ice sheet extent and snow cover.
However, no correlation was observed, indicating that any relationship between modelled preindustrial ice sheet extent and temperature increases is complex and nonlinear.
Most modelling studies of this period do not treat ice sheet extent and elevation or CO2 concentration prognostically, but specify them as boundary conditions.
Ice core data suggest that the Greenland Summit region was ice - covered during this period, but reductions in the ice sheet extent are indicated in parts of southern Greenland.
Albedo depends of flora, geology and ice sheet extent, these things can be worked out.
