effect of melting glaciers

Climate change is affecting the world now, and one of the most obvious ways is by melting glaciers.This month, the National Aeronautics and Space Administration's Earth Observatory published satellite-based images showing how glaciers in two parts of the world, Antarctica and Asia, have responded to warmer average temperatures. The warming atmosphere melts glaciers from above, while ocean water can erode the ice along the glacier's face. In fact, data shows that the North Atlantic has already become fresher over the past several decades. A lot of places all over the world depend exclusively on the constantly flowing water from glaciers that are melting in producing electricity.Reducing or stopping the flowing of water will mean stopping the production of electricity. Climate change, through accelerated glacial melting, may increase the quantity of nutrient additions to coastal ecosystems. Such changes would likely produce ecosystem changes – as high nutrient levels correspond with increased vegetation – but it is unknown what the exact changes would look like. The melting of glaciers depends on a variety of factors, the most important of which is the amount of solar radiation hitting the ice. The research visually displays the effects of climate change By Mathew Willoughby Research conducted by Andy Bach, an environmental geography professor at Western, may have found a positive side effect to the melting of Mount Baker’s glaciers due to climate change. However, the actual rise in sea level could be considerably greater than this. Shift in atmospheric rivers could affect Antarctic sea ice, glaciers. Glaciers gain mass through snowfall and lose mass through melting and sublimation (when water evaporates directly from solid ice). Fig 1. The glacier will keep receding over time and will finally vanish. As the Earth continues to warm and Arctic sea ice melts, the influx of freshwater from the melting ice is making seawater at high latitudes less salty and hence less dense. But even people who don’t care about glaciers will feel effects of the forces melting the ice. Effect of melting glaciers on the Earth's rotation and gravitational field: 1965–1984 Andrew S. Trupin, Andrew S. Trupin 1 Department of Physics and Cooperative Institute for Research in Environmental Sciences, University of Colorado, Boulder, CO 80309, USA. Receding glaciers expose geological material that used to be under them, Bach said. Glaciers that terminate in a lake or the ocean also lose mass through iceberg calving. This begins a cycle of warming and melting. Melting glaciers don’t just have massive implications for humans. A glacier is a large mass of snow and ice that has accumulated over many years and is present year-round. And the oceans are getting warmer. Melting glaciers may affect ocean currents Date: June 1, 2011 Source: University of Sheffield Summary: Scientists have used a computer climate … In many ways, Iceland is ground zero for climate change. By Guy Adema, Ronald D. Karpilo, Jr., and Bruce F. Molnia. As the impact of global warming has accelerated, melting from glaciers and ice sheets has become the main contributor. The massive Greenland ice sheet is shedding about 300 gigatons of ice a year into the ocean, making it the single largest source of sea level rise from melting ice. The five warmest years in the ocean in the … More solar energy is absorbed at the surface and ocean temperatures rise. The balance of glaciers and the surrounding environment can drastically affect ecosystems. Warmer water temperatures delay ice growth in the fall and winter, and the ice melts faster the following spring, exposing dark ocean waters for a …
