The properties of the climate system include not just familiar concepts of averages of temperature, precipitation, and so on but also the state of the ocean and the cryosphere (sea ice, the great ice sheets in Greenland and Antarctica, glaciers, snow, frozen ground, and ice on lakes and rivers).

Eyewitnesses said the glacier had barreled in like a fast train, dumping enough ice to fill 40,000 Olympic - size swimming pools.

This warm water reaches the coastline in places, where it triggers substantial melting of the floating parts of glaciers and leads to thinning of the ice upstream.

Studying surging glaciers could also offer insights into grander - scale ice flows with global consequences: the movements of the ice sheets in Antarctica and Greenland, which can change abruptly, altering the ice discharges that affect sea level.
