Preknowledge
climate changes in polar regions could affect mass balance of the polar ice sheets and the resulting changes in sea-level would have global impllications
 * Metereological records began on 1950
 * The dramatic thinning of glaciers in Western Antarctica is due to natural variation, and cannot be attributed directly to carbon emissions.- Nature Geosci.
