Global warming is causing glaciers to melt, and in the future, will glaciers in the North and South

The environmental problems faced by human beings can be divided into three categories, namely environmental pollution, ecological damage and resource shortage, some environmental problems have a large impact on a large scale, and even evolve into global environmental problems, the main global ones include global warming.

The hole in the ozone layer and acid rain.

problems, etc. Global warming is the most important environmental problem facing mankind today, and it is a global climate change problem formed by a series of complex factors including nature and humanity, which is manifested in the industrial revolution.

Since then, the global average temperature has shown a fluctuating upward trend.

There are two main anthropogenic causes of global warming, the first is that since the Industrial Revolution, human beings have used a large number of fossil energy sources such as coal and oil, thus emitting a large amount of greenhouse gases.

carbon dioxide goes to the atmosphere; On the other hand, human beings are very interested in being able to photosynthesize.

Large-scale development and destruction of green vegetation that absorbs carbon dioxide has been carried out, and tropical rainforests, known as the "lungs of the earth", have shrunk dramatically, reducing the ability of vegetation to absorb carbon dioxide from the atmosphere. As a result, the carbon dioxide content in the atmosphere increases, and the thermal insulation effect of the atmosphere is enhanced. Of course, the process of global warming also includes the cyclical changes in the Earth's climate itself, as well as methane in the polar regions.

of release and other natural causes.

Antarctic ice sheet. According to the current facts, in the middle of the 20th century, the global average temperature increased by about 9 days, and the onset of autumn frost was delayed by about 10 days in the middle and high latitudes of the Northern Hemisphere. Global warming has brought a range of impacts to the planet, including increased glacier melt and rising sea levels in the poles and high mountains.

Climate change, frequent occurrence of extreme weather phenomena in various regions, and alluvial impact on agricultural and other industrial activities. The melting of polar glaciers and the thermal expansion and contraction of seawater are the main causes of sea level rise, which threatens to submerge many coastal areas and low-lying island nations.

Global warming will continue for the foreseeable future, meaning that glaciers in the poles will continue to melt, but on current trends, it is unlikely that glaciers will melt in both poles by 2050. Based on the warming of the 20th century, we estimate that by 2050 the average global temperature will be about the same as in 2000, and the current Antarctic region.

The average annual temperature is about -25, so by 2050 the temperature in Antarctica will still be much lower than 0, and the glaciers will certainly not melt completely. However, in the relatively low latitudes of the Antarctic margin, the rate of glacier melt will accelerate, and more glacial meltwater will enter the ocean, exacerbating sea level rise to Nauru, Tuvalu and the Maldives.

and other countries will face an existential crisis.

Not necessarily. If we can reduce atmospheric CO2 concentrations in time, we can reverse global warming. If we continue to develop with high emissions, it may take only a few hundred years to melt the Arctic and Antarctic glaciers. So we are now actively delaying global warming and climate change.

It is possible that all of them will melt because global warming is accelerating, so in the future, the glaciers may melt completely.

It's really going to melt because our planet is warming globally right now, and it's warming very fast.

We are now facing global warming, which is caused by the destruction of the ozone layer by emitted carbon dioxide. As the climate continues to warm, glaciers will eventually melt completely.

The dangers of melting glaciers due to global warming include shortages of fresh water, overflooding of rivers, extinction of some animals, loss of coral reefs, and the return of deadly viruses.

As we all know, the Earth's climate is slowly warming, and due to the warming of the climate, the melting of glaciers on the Earth is accelerating. So what are the dangers of melting glaciers due to global warming? Let's find out.

01 Fresh water shortage on earth.

Ninety percent of the Earth's freshwater glaciers are in Antarctica. If glaciers melt too quickly, fresh water is lost into the ocean.

02 Excessive flooding of rivers.

03 Animal extinction.

If the Arctic and Antarctic ice disappear too quickly, polar bears will expose them to unfamiliar environments as the ice sheets melt, making it extremely difficult for them to find prey.

04 The disappearance of coral reefs.

Coral reefs on Earth will slowly disappear as they are no longer exposed to sunlight as they rise due to rising sea levels due to melting glaciers, affecting the survival of fish.

05 The return of a deadly virus.

If the ice melts too quickly, some trapped viruses and bacteria are in danger of being released, and humans could be threatened by deadly viruses.

Since human beings entered the industrial society, we have begun to use a large number of fossil fuels, emitting immeasurable greenhouse gases, originally according to the normal composition of the atmosphere, the energy of sunlight to the earth will be reflected by the earth A large part, but greenhouse gases, such as carbon dioxide, have intensified the absorption of reflected energy, so that the whole earth seems to be shrouded in a layer of insulation quilt. As industrialization intensifies, more and more greenhouse gases are emitted into the atmosphere, and if you want to change climate warming, you can only curb greenhouse gas emissions, but recent scientists have found that global warming1 causes Antarctic glaciers to melt and may put the earth into a Xiaoice period.

Recently, NASA released a report saying that 2020 was the hottest year on record, and after calculating the data recorded by thousands of meteorological stations around the world, the hottest year in 2020 reached the hottest in 2016. However, in 2016, the El Niño phenomenon caused the cold ocean currents on the ocean floor to rise to the surface, resulting in persistently high surface temperatures in the Pacific Ocean. Global carbon dioxide emissions have been greatly reduced in 2020 due to the pandemic, and the Pacific Ocean is not in El Niño in the second half of 2020, on the contrary, the Middle East Pacific has been in La Niña, which seems to have slowed down the rise in temperature, but it has not.

2020 was as hot as ever.

2020 will reach more than 1 degree Celsius above pre-industrial temperatures, which is close to the 2 degrees Celsius limit for global climate change set by the Paris climate conference, and we may not be able to meet this target. Is global warming only warm? In fact, the process of climate warming in China is most affected by the chaotic atmospheric circulation.

In winter, there is a stable temperature gradient from the North Pole to the equator, which allows the cold and warm air to flow steadily from west to east in the zonal circulation, but the warming of the climate causes the Arctic to warm up much more than the equator, which disrupts the stable temperature gradient. The frequency of warm high pressure over the Arctic region is increasing, and the warm high pressure will squeeze the Arctic vortex southward, causing cold waves in the northern hemisphere again and again, so excessive cold waves are also the cause of global warming.

Scientists are analyzing that melting Antarctic glaciers will lead to global sea level rise, and at the same time will increase the global ocean current velocity, and the cold ocean currents on the seabed will be turned up to the sea surface, and on the basis of the turbulence of global ocean currents, it will take away the heat from all over the world and let the world enter a cold Xiaoice period. In the analysis of the last global Xiaoice period, that is, at the end of the Ming Dynasty, the global temperature also rose by one or two degrees, after which the world entered the Xiaoice period. Since modern human beings do not have enough understanding of the factors that affect the global climate, the change of climate can only be theoretically reasoned about.

Perhaps global climate change is far from what we humans can currently predict.

Hello, in the foreseeable future, global warming will continue, that is, glaciers in the polar regions will continue to melt, but according to current trends, it is impossible for glaciers in both polar regions to melt by 2050. According to the degree of warming in the 20th century, the global average temperature will rise by 2050 compared with 2000, and the current annual average temperature in Antarctica is about -25, so by 2050, the temperature in Antarctica will still be much lower than 0, and the glaciers will definitely not melt. However, in the relatively low latitudes of the Antarctic margin, the rate of glacier melt will accelerate, and more glacial meltwater will enter the ocean, exacerbating sea level rise, and countries such as Nauru, Tuvalu, and the Maldives will face an existential crisis.

It will have very serious consequences, and it will also reduce the land area, expand the ocean area, and there will be a lot of conditions, and some ice-covered creatures will also appear, and it may also have a lot of bad effects.

The Antarctic region contains very large reserves of fresh water, and when the glaciers in the two places gradually melt, the sea level will continue to rise, and eventually many low-lying areas of the world will be "submerged", even at high altitudes, and there will be problems such as "backflow" of seawater. In addition, Siberia and other regions belong to the permafrost, and many local equipment is built on the permafrost, and the increase in temperature will inevitably lead to the destruction of infrastructure, traffic jams, and people's lives will also be affected. Whether it is the glaciers of the Arctic and Antarctic or the permafrost of Siberia, these places are "frozen" with the remains of many prehistoric creatures, including ancient bacteria and viruses, if these viruses reach people's lives as the ice gradually melts, it will have a huge impact on human beings, and even lead to the extinction of human beings.

Global warming, global sea level rise, will cause some plagues, the impact on people's living environment is very large, if the Arctic and Antarctic glaciers are melted, then the earth will be a furnace, completely unsuitable for human survival and development, some organisms on the earth will also disappear.

The first is that it will cause sea level to rise, and it will also inundate a lot of crops, and then it may also cause the atmosphere to warm, and there will also be a lot of extreme weather, which will destroy the biological chain.
