What happens to the freshwater that drains into the sea from a melting ice sheet or glacier?

Worldwide, seawater moves in a pattern of currents known as thermohaline circulation, or the global ocean conveyor. The melting ice causes freshwater to be added to the seawater in the Arctic Ocean which flows into the North Atlantic. The added freshwater makes the seawater less dense.

Why can’t we use the water in the icecaps and glaciers?

There may be frozen pathogens, which may require boiling before consumption. Another problem is with the logistics: people tend not to accumulate around cold regions, so one needs energy to transport the water to cities.

How does melting glaciers affect freshwater?

Melting glaciers can affect river runoff, and thus freshwater resources available to human communities, not only close to the glacier but also far from mountain areas. As glaciers shrink in response to a warmer climate, water is released from long-term glacial storage.

What happens to the water when glaciers melt?

Icebergs are chunks of glacial ice that break off glaciers and fall into the ocean. When glaciers melt, because that water is stored on land, the runoff significantly increases the amount of water in the ocean, contributing to global sea level rise.

What would happen if all the sea ice melted?

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. That’s because the ice doesn’t just melt.

Can we use the fresh water from the ice caps?

Even though icebergs are floating in salt water, the ice has no salt. It’s compressed snow. If you melted an iceberg you would get drinkable fresh water after you killed any germs. Icebergs have never been used as a major source of drinking water because of the costs and risks associated with moving them.

Can humans use fresh water that is stored in glaciers?

If we ever ran out of water could we use the water from the ice glaciers? A: In theory, yes. Some ice is sea ice, that is frozen sea water.

Do we get fresh water from glaciers?

About three-quarters of Earth’s freshwater is stored in glaciers. Therefore, glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth!
