Mass balance of polar ice sheets.
Recent advances in the determination of the mass balance of polar ice sheets show that the Greenland Ice Sheet is losing mass by near-coastal thinning, and that the West Antarctic Ice Sheet, with thickening in the west and thinning in the north, is probably thinning overall. The mass imbalance of the East Antarctic Ice Sheet is likely to be small, but even its sign cannot yet be determined. Lar...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولOverweight and Obesity the Major Problem of Present and Future
There are many evidences confirming that a_ BMI more than 25 will significantly increase the risk of cardiovascular problems and related diseases. BMI more than 30 will dramatically raise mortality rate. An increase in BMI will lead to an increase of mean blood pressure and blood cholestrol, and a decrease in HDL levels. In men with morbid obesity the risk of hypertemion and/or elevated cholest...
متن کاملMass balance of the Antarctic ice sheet.
The Antarctic contribution to sea-level rise has long been uncertain. While regional variability in ice dynamics has been revealed, a picture of mass changes throughout the continental ice sheet is lacking. Here, we use satellite radar altimetry to measure the elevation change of 72% of the grounded ice sheet during the period 1992-2003. Depending on the density of the snow giving rise to the o...
متن کاملThe future of ice sheets and sea ice: between reversible retreat and unstoppable loss.
We discuss the existence of cryospheric "tipping points" in the Earth's climate system. Such critical thresholds have been suggested to exist for the disappearance of Arctic sea ice and the retreat of ice sheets: Once these ice masses have shrunk below an anticipated critical extent, the ice-albedo feedback might lead to the irreversible and unstoppable loss of the remaining ice. We here give a...
