Melting glaciers contribute to sea-level rise, but measuring their mass loss over time is difficult. An analysis of satellite data on Earth's changing gravity field does just that, and delivers some unexpected results. The extent to which mass loss from ice-covered land areas contributes to sea-level rise is not known accurately, in part because previous global estimates use different techniques for glaciers, ice caps and ice sheets. The Gravity Recovery and Climate Experiment (GRACE) satellite… 
Regional sea level change in response to ice mass loss in Greenland, the West Antarctic and Alaska
Besides the warming of the ocean, sea level is mainly rising due to land ice mass loss of the major ice sheets in Greenland, the West Antarctic, and the Alaskan Glaciers. However, it is not clear
Potential for bias in 21st century semiempirical sea level projections
We examine the limitations of a semiempirical model characterized by a sea level projection of 73 cm with RCP4.5 scenario by 2100. Calibrating the model with data to 1990 and then simulating the
Sea-level rise impacts and responses: a global perspective
Coastal hazards have long been present and are evolving due to a variety of different drivers: the long-term threat of climate change, including sea-level rise, adds a new dimension to these problems
Increased mass over the Tibetan Plateau: From lakes or glaciers?
The mass balance in the Inner Tibet Plateau (ITP) derived from the Gravity Recovery and Climate Experiment (GRACE) showed a positive rate that was attributed to the glacier mass gain, whereas

Abstract. The Upper Indus River Basin (UIB) has developed the largest midlatitude mountain glaciers worldwide. Ice thickness and volume distribution are important prerequisites for glaciological and
Assessment of Spatial and Temporal Flow Variability of the Indus River
Considerable controversy exists among researchers over the behavior of glaciers in the Upper Indus Basin (UIB) with regard to climate change. Glacier monitoring studies using the Geographic
Chemical weathering across the western foreland of the Greenland Ice Sheet
The science of climate change: questions and answers
Earth’s climate has changed over the past century. The atmosphere and oceans have warmed, sea levels have risen, and glaciers and ice sheets have decreased in size. The best available evidence
Seasonal Snow Cover Change Detection Over the Indian Himalayas Using Polarimetric SAR Images
A snow cover mapping technique is proposed in this letter by exploiting the ratio of the seasonal variation of copolarized $(hh{-}vv)$ correlation coefficient and the total scattering power, which provides a very efficient index for snow characterization.


Recent contributions of glaciers and ice caps to sea level rise
Glaciers and ice caps, excluding the Greenland and Antarctic peripheral GICs, lost mass at a rate of 148 ± 30 Gt yr−1 from January 2003 to December 2010, contributing 0.41‬±‬0.08‬1 to sea level rise, which agrees well with independent estimates ofSea level rise originating from land ice loss and other terrestrial sources.
Glaciers Dominate Eustatic Sea-Level Rise in the 21st Century
The contribution of these smaller glaciers has accelerated over the past decade, in part due to marked thinning and retreat of marine-terminating glaciers associated with a dynamic instability that is generally not considered in mass-balance and climate modeling.
Increasing rates of ice mass loss from the Greenland and Antarctic ice sheets revealed by GRACE
We use monthly measurements of time‐variable gravity from the GRACE (Gravity Recovery and Climate Experiment) satellite gravity mission to determine the ice mass‐loss for the Greenland and Antarctic
Recent glacier mass changes in the Gulf of Alaska region from GRACE mascon solutions
Abstract The mass changes of the Gulf of Alaska (GoA) glaciers are computed from the Gravity Recovery and Climate Experiment (GRACE) inter-satellite range-rate data for the period April
Climate Change Will Affect the Asian Water Towers
It is shown that meltwater is extremely important in the Indus basin and important for the Brahmaputra basin, but plays only a modest role for the Ganges, Yangtze, and Yellow rivers, indicating a huge difference in the extent to which climate change is predicted to affect water availability and food security.
Mass balance of glaciers and ice caps: Consensus estimates for 1961–2004
Working with comprehensive collections of directly‐measured data on the annual mass balance of glaciers other than the two ice sheets, we combine independent analyses to show that there is broad
Geodetic and direct mass-balance measurements: comparison and joint analysis
This paper describes a new compilation of both direct and geodetic mass-balance measurements, develops a procedure to reduce diverse balance measurements over different time-spans to common
