The glaciers that are still left on earth are found in high elevations or arctic climates where the temperature is fairly cold year round. Most of the glaciers are receding at a rapid pace however due to global warming occurrences Global warming is also accelerated at the poles, which are also the arctic climates. While we may not notice a 1 degree change in a temperate climate, there may be a 3-5 degree change at the poles which drastically speeds glacial melt. When the top layer of ice and snow on a glacier melts, it forms a pool of water. This pool of water absorbs the suns heat instead of reflecting it like ice and snow does. This accelerates the melting even more, and the water will start to flow through fissures, or small cracks in the glacier. These fissures become large rivers of melt water flowing through the glacier to the solid land mass below. The water then proceeds between the land and ice to the lower elevations. At the poles, and in Greenland this is the sea. This causes the glacier to be able to slide downhill, to the ocean. When this melt-water flows into the ocean and land based glacial ice falls into the ocean, we get sea level rise. There have already been small levels of documented sea level rise, but it is predicted that it could reach 10 feet or more by the end of this century.
Global warming is causing glaciers to retreat and icebergs to break off more frequently and in larger sizes. As temperatures rise, glaciers melt at a faster rate, leading to rising sea levels and disrupting ecosystems. The increased melting of icebergs can also impact ocean currents and marine habitats.

Seasonal change of glaciers size in North and South pole is due to seasonal temperature variation. In winter (earth tilted away from sun), temperature drop and ice accumulated up and vice versa when the summer come (earth tilted toward the sun) temperature increase and ice melted. Now global warming is melting glaciers all over the world, and they are getting smaller.
The warming of the sea is part of global warming. If the earth warms up, then the oceans warm up too (but a little more slowly).
Heaps of earth moved by glaciers are called moraines. These are composed of a mixture of rocks, sediment, and debris that are picked up and transported by glaciers as they move and are then deposited as the glacier melts.

It means that the world is heating up.
glaciers are melting,sea level is rising,temps are up
well glaciers grow and retract based on the temperature of the earth. glaciers weight a lot. A bag of ice from the party store weighs 20lbs and is less then two cubic feet of ice. Now image the weight of a block of ice that is a mile high and hundred of miles across growing. It digs into the earth and pushes it around. As it grows it picks up boulders and so on and builds things up like hills or cuts things out like lakes. Likewise as it melts and retracts it dumps things that it picked up as it was growing and got frozen in the ice.

scientests have been finding out that the earth is warming up by methane
Glaciers are large masses of COLD. When they get smaller, the micro-climate nearby warms up, further speeding up more melting, which leads to slightly more warming, and so on.
Global warming affects glaciers by melting them. The water runs into the oceans, raising the sea levels.Global warming affects oceans by warming them. Warm water expands, so ocean levels are rising even further!

Global warming will make the earth hotter. Some parts of it will be wetter, and others drier, even becoming deserts. Tropical rainforests will probably die. Ice will melt and sea levels will rise changing the coastlines of most countries. Rivers that rely on ice from meting glaciers will dry up.
