Sentences with phrase «significant ice retreat»

Not exact matches

The glacier is currently experiencing significant acceleration, thinning and retreat that is thought to be caused by «ocean - driven» melting; an increase in warm ocean water finding its way under the ice shelf.

The only way that significant amounts of this mud could have been deposited as sediment in the sea would be if the ice sheet had retreated inland and eroded these rocks, say the team.

Since IPCC (2001) the cryosphere has undergone significant changes, such as the substantial retreat of arctic sea ice, especially in summer; the continued shrinking of mountain glaciers; the decrease in the extent of snow cover and seasonally frozen ground, particularly in spring; the earlier breakup of river and lake ice; and widespread thinning of antarctic ice shelves along the Amundsen Sea coast, indicating increased basal melting due to increased ocean heat fluxes in the cavities below the ice shelves.

Her work showed that polar bears, while best known for their life at sea or on sea ice pursuing seals, have been able, at least in some circumstances, to gain significant nutrition on land as well, scarfing down geese and goose eggs, grasses and other fare when sea ice is in retreat.

In addition to an overall retreat, IIRC one change since then has been that the first - year ice has broken through the Fram Strait, which seems significant since that hasn't been observed to happen before.

Recent estimates indicate that the Antarctic sea ice cover is expanding at a statistically significant rate with a magnitude one - third as large as the rapid rate of sea ice retreat in the Arctic.

Warm ocean water plays a significant role in melting glacial ice from below, and a better mapping of Antarctica's and Greenland's landforms beneath the ice suggests that ocean melting of the glacier fronts may play a more significant role than previously thought as the ice sheets retreat (under a global warming scenario).

Geothermal conditions impart a significant control on the ice sheet's transient response, particularly during phases of rapid retreat.

The retreat of glaciers and shrinking of the Greenland ice sheet in the Arctic, for example, is predicted to cause significant sea - level rise, changes in the salinity of our oceans, and altered feedback loops that will make the Arctic warm up even faster.

As researchers documented in this graph, the region had experienced increasing precipitation during the Little Ice Age, followed by a sharp drying trend that began in the late 1700s, which triggered Kilimanjaro's retreat long before CO2 ever reached significant concentrations.

A more significant ice extent retreat is expected in the Canadian / Alaska sector of Arctic due to enhanced warmer air inflow.

What is significant about this paper is that GHG forcing that is supposedly causing exponential, run - away warming, collapse of the polar ice sheets, retreat of the worlds glaciers, etc since around 1960 is not visible at all in the sea level record.

Updated information about the ice extent in the region indicates a significant retreat in the Barents and Kara seas; the ice extent in the Barents Sea is below the decadal means (Figure 4).

This sea ice retreat has significant effects on high - latitude ecosystems and on the evolution of climate change itself, through the change of Earth surface's reflectivity.
