    A geometric glacier model for sea-level change calculations (2000)
    In:  EPIC3Journal of Glaciology, 46, pp. 357-368
    Details
    Publication Date: 2019-07-17
    Description: Towards accounting for the dynamic response of glaciers and ice caps in the estimation of their contribution to sea-level rise due to global warming, a mass-balance degree-day model is coupled to a geometric glacier model. The ice dynamics are treated implicitly in the geometric model by using scaling parameters that have been extensively investigated in the literature. The model is tested by presenting a case-study of the glacier Hintereisferner, Austrian Alps. The results are compatible with geomorphological data and other modelling studies. An estimate is made of the volume decrease due to initial disequilibrium. An extensive sensitivity study using generalized glacier shapes and sizes allows a comparison of results with dynamic theory. According to the geometric model, glaciers with a narrowing channel change more with a change in mass balance than glaciers with a widening channel, due to their shape and the way in which that shape changes with a changing climate. Also their response time is longer. As time progresses after a mass-balance perturbation, the longer response time for continental glaciers compared to glaciers with a larger mass turnover offsets the effect of their smaller static sensitivity. Thus, although for the next century we may expect greater changes in volume from alpine glaciers, the equilibrium or committed change is greater for the continental glaciers.

    The Potential for Sea Level Rise: new estimates from Glacier and Ice Cap area and volume distributions (2005)
    In:  EPIC3Geophysical research letters, 32, L055020.
    Details
    Publication Date: 2019-07-17
    Description: Projections of sea-level rise from mountain glaciers and ice caps for the next century and beyond should be based on an assessment of the ice available for melting. Projections to date are based on all regions except Greenland and Antarctica (the latter are considered separately by the IPCC), yet no sound estimates for the appropriate volume of ice and its potential for sea level rise are evident in the literature. An ice cap data set is compiled allowing the separate treatment of glacier area coverage data. Glacier inventory data are comprehensive enough in some regions to allow the estimation of glacier size distributions. The differences in the distributions are related to a metric of the regional topographic variability, allowing glacier size distributions to be estimated on a 1o latitude longitude grid of cells containing glaciers. Appropriate volume-area scaling for glaciers and for ice caps gives global estimates of glacier and ice cap volumes by size class. This leads to an estimate of the total ice volume of 0.087 ± 0.010 106 km3 and a sea level rise equivalent of 0.241 ± 0.026 m. The glaciers and ice caps contribute 41% and 59% to these estimates respectively. These values are based on data sets compiled during several decades, mainly in the second half of the 20th Century. We compare our results to published results that include the glaciers and icecaps at the margins of the Greenland and Antarctic ice sheets

    Glaciers and their contribution to sea level change (2002)
    In:  EPIC3Physics and chemistry of the earth, 27, pp. 1445-1454
    Details
    Publication Date: 2019-07-17
    Description: Increased melting of glaciers and ice caps, excluding Greenland and Antarctica, will probably represent the second largest contribution to global sea level rise by 2100. The temperature sensitivity of sea level rise depends upon the global distribution of glacier areas, the temperature sensitivity of glacier mass balance in each region, the expected change of climate in each region, and changes in glacier geometry resulting from climate change. None of these are particularly well known at present. Improvements in global climate models should eventually give better information about expected climate changes in regions where glaciers occur but there is also much work for glaciologists. For example, glacier areas, altitudes, shape characteristics and mass balance sensitivity are still not known for many glacierized regions and ways must be found to fill gaps.

    The contribution to sea level change from different glacier regions indicated by two key parameters (2002)
    In:  EPIC3European Geophysical Society XXVII General Assembly, Nice (F)April 2002., 21
    Details
    Publication Date: 2019-07-17
    Description: For predictions of sea level change, there are two stages to the modelling of glacier response to climate change. Firstly, to calculate the change in mass balance over the glacier areas (static response) and secondly to calculate the change in glacier area and volume (dynamic response) that results from the mass balance change. The static response is primarily controlled by climate while the dynamic response depends on glacier geometry as well as the static response. The change in glacier volume can be characterised by a parameter from each of the two calculation stages. For the mass balance, the static sensitivity is the change in mass balance from the initial profile due to a 1 K temperature increase at the mean glacier altitude for a particular region. For changes in glacier geometry (in particular the area/altitude distribution) the relevant parameter is the glacier response time. We present estimates of these two parameters for different glacier regions, reflecting different climatic regimes and topography. We discuss the implications for the contribution to sea level change from the different regions.
