Sentences with phrase «ice shelf breakups in»

When such events do occur (such as flooding in Bangladesh, ice shelf breakups in Antarctica) they occur in remote locations that are far from the concerns of average Americans, and making the link between these events and individual day to day concerns is very difficult to make.

Not exact matches

«There are suggestions in the literature that accelerated breakup of ice shelves will lead to rise of sea level by several meters by the end of the century,» Godin said.

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.

An additional new feature is the increasingly visible fast dynamic response of ice shelves, for example, the dramatic breakup of the Larsen B Ice Shelf in 2002, and the acceleration of tributary glaciers and ice streams, with possible consequences for the adjacent part of the ice sheeice shelves, for example, the dramatic breakup of the Larsen B Ice Shelf in 2002, and the acceleration of tributary glaciers and ice streams, with possible consequences for the adjacent part of the ice sheeIce Shelf in 2002, and the acceleration of tributary glaciers and ice streams, with possible consequences for the adjacent part of the ice sheeice streams, with possible consequences for the adjacent part of the ice sheeice sheets.

This flow of ice, fed by the continuous formation of new ice on land and culminating in the breakup of the shelves on the outer fringe and the calving of icebergs, is not new.

Small changes in global sea level or a rise in ocean temperatures could cause a breakup of the two buttressing ice shelves.

Subsequent work pointing in the same direction included De Angelis and Skvarca (2003), who found that Antarctic grounded ice surged after an ice shelf breakup, and Bindschadler et al. (2003), who reported that a major West Antarctic ice stream started and stopped flowing as the tide went up and down.

In this case the thinning and resultant structural weaknesses preconditioned the ice to rapid breakup, which proceeded to lose only the preconditioned portion of the ice shelf.

IMO, the strongest argument for sea ice decline over the last decade for being unusual and at least in part attributable to global warming is this (from Polyakov et al.): The severity of present ice loss can be highlighted by the breakup of ice shelves at the northern coast of Ellesmere Island, which have been stable until recently for at least several thousand years based on geological data.
