| Zusammenfassung |
| A single large glacier can contain tens of millions of times the mass of a
small glacier. Nevertheless, very small glaciers (with area ≤1 km2) are so numerous that their contribution to the world's
total ice volume is significant and may be a notable source of error if
excluded. With current glacier inventories, total global volume errors on the
order of 10% are possible. However, to reduce errors to below 1%
requires the inclusion of glaciers that are smaller than those recorded in
most inventories. At the global scale, 1% accuracy requires a list of all
glaciers and ice caps (GIC, exclusive of the ice sheets) larger than 1 km2, and for regional estimates requires a complete list of all
glaciers down to the smallest possible size. For this reason, sea-level rise
estimates and other total mass and total volume analyses should not omit the
world's smallest glaciers. In particular, upscaling GIC inventories has been
common practice in sea level estimates, but downscaling may also be necessary
to include the smallest glaciers. |
