what effect will melting glaciers have globally?
447317
Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.

Impacts. Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.

Climate change and polar bears. Temperatures in the Arctic are rising at least twice as fast as the global average and sea ice cover is diminishing by nearly four per cent per decade. The loss of sea ice affects polar bears' ability to find food, studies show.

The effects of global warming in the Arctic, or climate change in the Arctic include rising air and water temperatures, loss of sea ice, and melting of the Greenland ice sheet with a related cold temperature anomaly, observed since the 1970s.

> Since the end of the last ice age to the present day, sea level has risen by around 125 metres. This has natural as well as man-made causes. However, the human-induced greenhouse effect is intensifying this process. Its main effects are thermal expansion of water and melting of glaciers.

Changes in the amount of sea ice can disrupt normal ocean circulation, thereby leading to changes in global climate. Even a small increase in temperature can lead to greater warming over time, making the polar regions the most sensitive areas to climate change on Earth.

The International Panel on Climate Change (IPCC) Fifth Assessment Report estimates that the upper ocean (surface to 750 m deep) has warmed by 0.09 to 0.13 degrees C per decade over the past 40 years. ... Global warming also has an enormous impact with respect to melting glaciers and ice sheets.

Powerful volcanic eruptions will likely get more frequent in the future, scientists say. A recent paper found a link between glaciers and volcanism. As glaciers retreat because of climate change and other causes, volcanic activity tends to increase, according to the analysis.

First, warmer temperatures cause ice on land like glaciers and ice sheets to melt, and the meltwater flows into the ocean to increase sea level. Second, warm water expands and takes up more space than colder water, increasing the volume of water in the sea. Sea level rise will hit the coasts the hardest.

A glacier is a perennial accumulation of ice, snow, water, rock and sediment that moves under the influence of gravity. A glacier forms when winter snowfall exceeds summer melting. Many years of accumulation result in compaction of the bottom layers of snow, turning them to ice.

Globalization affects climate change negatively by promoting global production and international trade. A predominant factor in the emission of GHGs is its direct relation to world gross domestic product, not only in manufacturing but also industrial agriculture and transportation.

On a very basic level, the problem is changes in the climate, which appear to be causing ice in the Polar Regions to melt. This in turn is causing many changes including a rise in sea levels, and damage to arctic environments, which is also greatly affecting wildlife.

Global climate change affects a variety of factors associated with drought. There is high confidence that increased temperatures will lead to more precipitation falling as rain rather than snow, earlier snow melt, and increased evaporation and transpiration.

What are the effects of melting glaciers on sea level rise? Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.

As the climate warms, it changes the nature of global rainfall, evaporation, snow, stream flow and other factors that affect water supply and quality. Specific impacts include: Warmer water temperatures affect water quality and accelerate water pollution.
