Snow and ice cover less of the Earth's surface as a result of melting due to an increase in global temperature, which also lowers albedo. More energy is absorbed due to the decrease in albedo, which leads to increased warmth and melting.
Global temperature is significantly influenced by the equilibrium between the amount of solar energy reflected and absorbed by the Earth's surface. Snow, ice, and water on Earth have different capacities to reflect and absorb solar energy, and melting polar ice triggers a positive feedback loop that hastens global warming.
Pollution, including soot, decreases the albedo of ice and speeds up melting.

Answer:
Three conditions are necessary to form a glacier: (1) Cold local climate (polar latitudes or high elevation). (2) snow must be abundant; more snow must fall than melts, and (3) snow must not be removed by avalanches or wind
