What are the consequences of glacier melting, the consequences of glacier melting

That's a lot! Very serious !

1.As sea levels rise, people living on lower islands and coastal cities are at risk of being inundated.

2.Polar bears live on the ocean ice, where they hunt seals and use passages in the ice to move from one area to another. More and more melting ice will make it impossible for them to gain a foothold on the sea.

Some climate models**: By the end of the century, the Arctic Ocean, which is now only traversed by icebreakers, will likely become an ice-free ocean in the summer. If that happens, polar bears are likely to become extinct.

3.Although some regions will increase crop yields due to climate change, negative impacts are more likely to dominate as the climate warms. Africa, already in a hot zone, will be particularly vulnerable, the findings warn

As the climate warms, the number of hungry people in Africa will increase dramatically.

4.Global climate and atmospheric circulation have accelerated the rate of temperature increase in the polar regions, with more serious consequences.

5.Ocean currents that would revolutionize the world's oceans. Because there is a thermohaline cycle between the global surface and bottom ocean currents, and the main thing is that the North Atlantic warm current absorbs a lot of lighter and colder polar water after entering the Arctic and sinks, and once the glaciers melt in a large area, the North Atlantic warm current will be blocked from going north or even forced to go south, and the global thermohaline cycle will be interrupted, resulting in more serious consequences.

What I know is that Shanghai is going to fall into the sea, and the low-latitude islands will disappear. Ha ha.

The consequences of melting glaciers are, first, rising sea levels, some cities in low-altitude areas may be covered by seawater, second, changing the landform, inducing floods, landslides and other phenomena, third, freshwater scarcity, the loss of fresh water from glaciers into the ocean, and fourth, the extinction of animals, and the loss of habitat for animals to the verge of extinction.

There is a lot of natural gas under the glacier, some is a toxic gas, some is a greenhouse gas, and if the glacier melts, a large amount of gas is released into the atmosphere, which has the potential to accelerate global warming.

Since ancient times, viruses, bacteria, and other substances have become extremely inactive in the cold conditions of glaciers, and if the glaciers melt, the viruses of the past may be released and slowly circulated to the places where humans live through air convection, causing disease disasters. Chain.

It takes a process for glaciers to melt to affect human life, but it will directly affect the lives of local animals, who will lose their homes, food, etc., and eventually die.

1. Cause sea level to rise.

Scientists believe that the melting of ice sheets and mountain glaciers over the past century is one of the reasons for the 10-25 cm rise in global sea levels. Nowadays, the number of rising sea levels due to melting glaciers is increasing. If the Antarctic ice sheet were to disintegrate, it would cause global sea levels to rise by nearly 6 metres.

If both the two major ice sheets in the North and South Poles were to melt, the result would be a rise in sea levels of nearly 70 metres.

Rising sea levels caused by melting glaciers will inundate large areas of the coast, leaving unrest for the people who live in these areas, who make up half of the world's population. All coastal areas will be turned into a vast ocean, and New York will only be able to talk about the rooftops of the United Nations building and a few skyscrapers, and Paris may only see the top of the Eiffel Tower, while dozens of low-lying countries such as the Netherlands and the United Kingdom will cease to exist.

2. The global climate has changed significantly.

Glaciers, especially large polar ice sheets, reflect sunlight in large quantities, helping to keep the Earth's temperature from rising. However, when glaciers melt, exposed land and water surfaces absorb solar heat, causing ice to melt more, and the ripple effect is bound to accelerate the process of surface warming, which contributes to climate warming. However, the colder ice water in the Arctic can have a cooling effect on parts of Europe and the eastern United States, and the flow of ice water into the North Atlantic Ocean could disrupt the oceanic circulation patterns there, which in turn could affect global climate change.

It causes severe cold in winter, blizzards, high temperatures in summer, torrential rains, hurricanes, and floods. Extreme weather is happening more and more frequently.

3. The ecological environment has been damaged.

The melting of glaciers has destroyed the living environment of some animals and plants, and also posed a threat to the living environment of human beings. There have been reports of polar bears struggling to find food in relation to ice sheet changes and softening under weight; Penguins and seals in Antarctica have also changed their habits and breeding patterns due to declining sea ice and rising temperatures; Microorganisms buried in ice sheets hundreds to tens of thousands of years ago were exposed by glacier melting, and their spread can have a certain impact on human health.

1. Cause sea level to rise.

2. The global climate has changed significantly.

3. The ecological environment has been damaged.

1. Shortage of fresh water.

Ninety-seven per cent of the Earth's water is sea round wax water, and only 3 per cent is fresh water, which should meet the needs of more than 7 billion people on the planet. About 75% of freshwater is trapped in glaciers, and 90% of freshwater-bearing glaciers are located in Antarctica. As glaciers melt at an accelerated rate, more fresh water is lost into the ocean, where it mixes with salt water.

The ice found in the mountains and highlands of inland rivers** is also receding, and there will soon be no fresh water for the growing population.

2. Excessive flooding.

The accelerated melting of glaciers has created more water for rivers to treat, which overflows and floods areas where streams flow from glaciers. With no water harvesting plan, this ended up displacing people and animals and destroying farms and residential areas. As the amount of water increases, tides and sea levels are already rising in low-lying areas along coastal areas around the world.

3. Animal extinction.

Polar bear populations have been declining for years due to the disappearance of Arctic and Antarctic ice. Polar bears have adapted to the cold conditions in these areas, but as the climate warms and the ice sheets melt, they are exposed to unfamiliar environments. Evolution takes millions of years, which is a time frame they can't afford.

The loss of locust ridges in this habitat has also affected their food**, and as a result, they are now an endangered species.

4. The disappearance of coral reefs.

Coral reefs play a vital role in the ocean, they provide shelter for a quarter of the animals that live in the ocean, regulate oxygen and carbon dioxide, and protect coastlines. They usually grow in shallow tropical waters, where they synthesize sunlight. However, as sea levels rise, coral reefs across the planet are dying out as they are no longer exposed to adequate sunlight, which directly affects fish populations, which in turn affects the people who depend on the ocean for their survival.

Therefore, the food shortage crisis is imminent.

5. The return of deadly diseases.

Ice is a purifier, and for years, the Earth's cold glaciers have been absorbing harmful chemicals, banning airborne pesticides, and trapping ancient viruses and bacteria that have become inactive in cold conditions. As the ice continues to melt, some of the trapped viruses, bacteria, and chemicals are in danger of being released back into circulation, and if this happens, humanity could face another return of deadly diseases.

6. Methane gas release.

There is a lot of natural gas under the glacier, and one of them is methane, which is not only toxic but also a greenhouse gas. After the glacier melts, it becomes lighter as the crevasse forms. These movements create cracks through which large amounts of methane gas are released into the atmosphere, further accelerating global warming by trapping heat from the surface.

It is estimated that if the current rate of global warming continues, the Arctic could release more than 50 billion tons of methane within a few years.

Melting glaciers can also lead to the rediscovery of viruses that have been frozen for a long time. Previously, a scientific research team found an unknown virus in the thawed glaciers on the Qinghai-Tibet Plateau, and this phenomenon may also be staged in the Antarctic region, because the Antarctic continent may have lived a rich variety of creatures, their bodies were buried underground after death, and the residual viruses in the body after being covered with ice and snow also entered a state of dormancy. Once the glaciers melt, these dormant viruses will have a chance to revive and enter nature and human society through air and flowing water.

From this point of view, humanity must also be prepared for the invasion of unknown viruses in the future. The most obvious direct effect of melting glaciers is that it causes sea levels to rise, which in turn inundated much of the land that is already inhabited by humans. In 2013, National Geographic magazine in the United States published a report on glacier melting, which pointed out that if all the ice on the earth melted, then the entire Atlantic coast could be submerged, and the entire continent of Florida in the United States could be submerged by seawater.

In addition to the Atlantic coast, the world's famous cities such as Tokyo, New York, and Jakarta will be affected by the invasion of the sea. Before these large cities were submerged, people flocked to higher elevations to escape the disaster, leading to more refugee problems.
