Why+are+the+glaciers+melting?

Because of global warming. Global warming is created when pollution we create caused by green house gases such as co2 stops the hot air from the sun escaping which is slowly melting the ice caps. When the sun heats up earths surface which generates energy outwards. The greenhouse gasses contain the heat. Because of all the worlds mechanization greenhouse gasses trap a lot more heat making the glaciers melt even faster. .
