TI: Acceleration of Mass Inflow from Glaciers to the Ocean

AB: Net melt-water inflow defined here as the additional mass (B) contributed by glaciers to the water cycle and to the ocean resulted from negative mass balance of glaciers averaged worldwide. Net melt-water inflow has been contributed of about 20-30% of total rise in the sea level, but (B) believed to be the dominant component of mass flux, because the steric component does not contribute into this. Acceleration in (B) flux from glaciers to the ocean, observed directly over the last decades, may affects the changes in gravitational field and oblateness of Earth, and may regionally affects of water salinity, temperature and circulation. I use here the results of direct measurements of (B) from about 300 individual glaciers worldwide averaged by mountain and subpolar systems to show acceleration in glacier contribution to mass input to the ocean over the last decades. I will also show on how this input shifts in time from the Northern and Southern hemispheres.
