Sentences with phrase «sheets respond to climate change»

Researchers hope to incorporate all of these factors into computer models of ice sheets, which still struggle to mimic how real ice sheets respond to climate change.

It's the fast - moving ice that determines how the ice sheet responds to climate change on a short timescale,» said Robert Bindschadler, a NASA scientist at the Goddard Space Flight Centre in Maryland, one of the study's co-authors.

Not exact matches

Their field - based data also suggest that during major climate cool - downs in the past several million years, the ice sheet expanded into previously ice - free areas, «showing that the ice sheet in East Greenland responds to and tracks global climate change,» Bierman says.

A report in the last issue of Nature finds that between April 2002 and April 2006, the rate at which southern Greenland's ice liquefied jumped by 250 percent — supporting the idea that the Greenland ice sheet responds quickly to slight changes in climate.

A new study suggests some of Antarctica's ice sheet grows from the bottom up, adding a new wrinkle to efforts to predict how the continent's glaciers will respond to climate change.

«Simply put, the shape of the ice sheet and the contact with the ocean makes it likely that these areas respond more pronouncedly to changes in climate boundary conditions — be they atmospheric, oceanic or glaciological.»

However, effec - tive communication with the public of the urgency to stem human - caused climate change is hampered by the inertia of the climate system, especially the ocean and the ice sheets, which respond rather slowly to climate forcings, thus allow - ing future consequences to build up before broad public con - cern awakens.

Implications include (i) the expectation of additional global warming of about 0.6 °C without further change of atmospheric composition; (ii) the confirmation of the climate system's lag in responding to forcings, implying the need for anticipatory actions to avoid any specified level of climate change; and (iii) the likelihood of acceleration of ice sheet disintegration and sea level rise.

The time needed for ice sheets to respond to climate change is uncertain, and there are proponents for time scales covering a huge range.

IceBridge is a six - year campaign to survey and monitor areas of Earth's polar ice sheets, glaciers and sea ice and how they are responding to climate change.

A significant uncertainty in future projections of sea level is associated with dynamical changes in the Antarctic and Greenland ice sheets and a key aspect of this uncertainty is the role of ice shelves, how they might respond to climate change, and the effect this could have on the ice sheets.

His research focuses on understanding the interactions of ice, ocean and climate, in particular using imaging radar observations from satellites and airplanes to determine how the ice sheets in Antarctica, Greenland and Patagonia will respond to climate change and affect global sea level.
