Governments and authorities can also consider improving management of water resources, by creating more efficient irrigation systems; refining water quality in rivers near cities; and carrying out reforestation of species that contribute to preserving mountain ecosystems. But as glaciers grow, they preserve pollutants from the contemporary environment. As glacier melts, cities and towns close to them will intially have more water. Also, because revegetation of terrain is slower at high altitudes, deglaciated areas will be subject to erosion and decreased stability, heightening the need to protect buildings, roads, communication links, and other structures. Because of climate change, many glaciers are now melting, and those pollutants are once more being released. They started melting rapidly back in the 1860s. But over time, the water the glaciers supply will dwindle, and some may even experience avalanches and floods. Also, because revegetation of terrain is slower at high altitudes, deglaciated areas will be subject to erosion and decreased stability, heightening the need to protect buildings, roads, communication links, and other structures.

And, by virtue of glaciers’ relationship with climatic changes, what I’ve observed is that more and more, the line between the two blurs. Things start going wrong when the water that is melting is more than the snow that is replacing it. This ultimately leads to the melting of glaciers. This diminishing of the snow cover earlier in each year causes the glacier ice to melt faster and retreat. The team measured the effect the soot would have had on glaciers at the time in terms of equivalent changes in air temperature. Carbon dioxide emissions are one big culprit. Mountain glaciers have been in retreat for several decades, but what scientists are now learning is the considerable factor air pollution plays in their decline. Glacier - Glacier - Heat or energy balance: The mass balance and the temperature variations of a glacier are determined in part by the heat energy received from or lost to the external environment—an exchange that takes place almost entirely at the upper surface. When these particles settle on the snow blanketing glaciers, they darken the snow surface, speeding its melting and exposing the underlying glacier ice to sunlight and warmer spring and summer air earlier in the year. The glaciers will initially provide extra runoff from melting; but as the ice diminishes, the runoff will wane.
