ice fields in South America, slowly
melting to feed into a vast network of turquoise rivers and lakes, with water so pure you can drink it!
Regional variations arise because the Earth's gravity
field is affected in multiple ways by the
melt of
ice, due to the direct effect of surface mass changes (the gravity
field is determined by the distribution of mass), the consequent deformation of the Solid Earth (removing a load causes the Earth's surface to rebound, which in turn changes the distribution of the Earth's mass), the consequent redistribution of ocean water (the ocean surface is shaped by the gravity filed) and perturbations of the Earth's rotation axis (because of mass redistribution).
However, there is both theoretical and observational evidence that
melting now occurs on the horizontal surfaces of the Kilimanjaro Northern
Ice Field, and contributes to ablation [Moelg and Hardy 2004; Thompson et al 2002].
And there are some other factors as well, like changing ocean currents or changes in the gravitational
field (due to
