Why global warming causes a sudden cooling climate

In fact, the question is very simple, everyone knows that ice melts or sublimates to absorb heat! When global warming increases the temperature, the melting of glaciers and icebergs on the earth accelerates, and the melting of glaciers and icebergs needs to take away a large amount of heat, and then through heat transfer and diffusion, the climate of places other than icebergs and icebergs is suddenly cooled! However, the thermal expansion and contraction of the air will not make it cooler in summer, because in summer the temperature is high and the atmospheric pressure is also high, and the apex will flow towards the poles (except in special cases), and in winter, it will shrink towards the equator, and the cold air at the poles will pour in in large quantities!

Resulting in a cold chill in winter!

The last 2.5 million years of Earth's history is known in geoscience as the Quaternary Ice Age. During this period, there were four large-scale subglacial and interglacial alternations around the world.

Between the last glacial period and 11,000 years ago, the large ice sheet of North America continued to melt and retreat due to climate warming, and a large amount of ice meltwater flowed into the Atlantic Ocean, especially through the Mississippi River system into the Gulf of Mexico, which caused the temperature of the warm water in the Gulf of Mexico from south to north to drop sharply, resulting in a sharp cooling of the climate in North America near the North Atlantic, especially in northern Europe, and prompting the Arctic ice sheet in northern Europe to expand southward. On the North Atlantic coast, the receding of the ice sheet and drastic changes in the temperature of the sea have led to abnormal weather conditions, with sudden** sea levels and various weather and marine disasters one after another.

The above is the scientific background of the film "The Day After Tomorrow", but the film compresses the cold and warm changes that have occurred on the earth for thousands of years and the catastrophic landscape caused by them into a few days to enhance the appeal and sensational effect of the work.

I think that now the world is warming, we will all be killed by heat, because the most suitable temperature we can accept now is 26 degrees, and there are not many changes to the core, so sometimes the temperature in some areas is as high as 38 degrees, or the kind of global warming that is very hot and hot up to 40 degrees Celsius or something is really that kind of carbon dioxide every day, and then the environment may be affected. I think global cooling may be even more terrifying. Because if the world is cold, in fact, many crops generally prefer the warmer season, and if the world warms, many crops are basically difficult to grow.

And then there will be a lot of famine in the area, that's what I think. And if the world is cold, well, I think it's very bad, because people generally like a warmer environment, often belong to that kind of cold weather, or have a certain impact on people's bodies, so I think global warming and global cooling are not good, the best kind of weather is controlled in people's nuclear digging suitable for that temperature, it is very good, and ginger can also bring us a good life, a good environment.

The earth is now in a state of continuous global warming. ......Summers are getting hotter and hotter, winters are no longer cold, and special weather is increasing, and we are already deeply aware of the harm caused by global warming.

At this point, some people may wonder how much better it would be if the world was getting colder......

These people may feel that we are currently in a period of global warming, and that the weather is too hot. ......Wouldn't it be ......better if the global climate could be cooler, neutralize the warming climate, and make the global temperature more pleasant

But the reality is far from idealistic. ......Once the global climate starts to get colder, the situation will get even worse!

The reason why this collapse is said is because of the following reasons:

1. The world is getting colder, and the crops will be lost.

Crops have requirements for the growing environment. ......High temperatures can increase the photosynthesis of crops, so global warming does not necessarily affect the growth of crops. ......But once the world gets colder, crops won't be able to survive at all, resulting in crop failure.

This will seriously affect our lives.

2. The world is getting colder, and fresh water will freeze.

The world will get colder, and the water will freeze. ......And if the world cools and all freshwater freezes, we will lose our water supply, which will also seriously affect our survival.

3. As the world gets colder, there will be no suitable place to live.

Whether we live or work, we need to find a suitable place to live. ......This suitable place to live must meet the requirements of the right temperature. ......Once the world cools, we will lose our habitat and will not be able to survive.

Therefore, although global warming is not good for our survival, global cooling is actually more harmful to us. ......Only when we have the right temperature on the earth can we live a better life. ......Therefore, protecting the environment is of paramount importance to us!

Humans may not be able to successfully resist global warming, and we boast that we have intelligence and civilization, far superior to dinosaurs and trilobites, which dominated an era. But what cannot be denied is that we are always limited by the environment, and the slightest change in the environment is reflected in human society. For example, the climate entered the Xiaoice Age, food production was greatly reduced, and nomads plundered everywhere for food and livestock to solve the most basic survival problems.

Climate has always been a big problem related to human survival, and this problem happens to be difficult for us to solve, and even ** cannot be 100% certain. In particular, extreme weather caused by climate change is coming.

In less than 300 years since the Industrial Revolution began, greenhouse gas emissions have caused global warming. Extreme weather and everything are a chain reaction that makes us suffer. Today's global climate is still unstable, and the protective measures we take now do not have an immediate effect.

It is easy to destroy, but it is too difficult to repair, and the wreak and tear of the past 300 years cannot be repaired in a short period of time, like those glaciers that have melted and collapsed ice shelves, how can they be repaired?

The Earth has been getting hot like this, and sooner or later it will become a second Venus. Venus is a prime example of the greenhouse effect, with an atmosphere full of greenhouse gases, numerous surface volcanoes, and temperatures above 400 degrees Celsius all year round. Phosphine, which was discovered on Venus some time ago, is speculated to be evidence of the existence of life.

However, according to the current state of knowledge, there is no life on Venus at all, and the environment is too harsh.

Compared to global warming, if the world is cold, the world will also be devastating, and neither cold nor heat is suitable for the growth of living things. Humans are also unable to adapt to large fluctuations in temperature.

To put it simply, as the world gets colder, human beings need more energy to withstand the cold. impact on industrial agricultural production. If plants do not grow, the food that human beings rely on for survival will cause crisis tension.

Global cooling is the equivalent of an ice age. Humanity wants to survive the Ice Age. It is very difficult, and all the plants in the animal kingdom are frozen to death, and they cannot survive. It is almost impossible for a human species to exist on Earth.

Therefore, global cooling is unlikely to allow humans to exist. Protecting the earth's environment and the planet on which we all depend is the crisis that contemporary mankind is facing. Start with yourself and reduce white pollution.

Reduce carbon emissions, save every drop of water, every kilowatt-hour of electricity, every grain of food, and make a modest contribution to environmental protection.

What will happen to the world if the world cools compared to global warming? Both are terrible.

First of all, the temperature plummets, and some wild plants stop growing, and they can freeze to death. This naturally affects the vegetarians who feed on these plants, who are starved of food, and even if some animals are hardy, they will starve to death without food. Later, the large carnivores that fed on these animals also fell, and most of the terrestrial animals would perish.

And what about marine life? You might think that being under the ice doesn't have much effect on them. In the case of the Ordovician Ice Age, it may have been when gamma rays hit the earth, and gamma rays roasted the atmosphere, causing the molecules in the air to combine into a void of harmful gases to block the sunlight and enter the ice age.

At that time, it was all marine life, which caused the extinction of more than 90% of all living things. It can be seen that the impact of global cooling on living organisms, even marine organisms, is enormous.

In addition, the Earth is warming up because the amount of carbon dioxide in the atmosphere is higher, and the rise in carbon dioxide will carbonate the seawater, which will then affect the survival of marine microorganisms. The death of marine microorganisms causes the food chain to break down, which then spreads to the entire ecosystem, and the end result is a decrease in oxygen and an increase in carbon dioxide levels. Therefore, global warming is also very harmful.

The heat dissipation rate slows down as the average temperature decreases, and is limited by the greenhouse gases emitted by human civilization. Global cooling will give humans ample time and reason to adjust the Earth's climate, such as by scattering cinders on polar regions and glaciers to reduce reflectivity, and absorbing the heat of sunlight to melt excess ice. In general, humans don't need to maintain the current temperature, and the average temperature is about 1 degree Celsius colder than it is now.

Lower global mean temperatures would lead to the expansion of land glaciers and polar ice sheets, as well as increased cloud cover in some areas, which would increase the average reflectance in many places and promote further cooling, albeit to a limited extent. As the average temperature drops, the climate will be milder in many places, but in some places near the poles, winters will be cold enough to be unsuitable for unprotected humans to move outdoors.

Even if there is no sunlight at all, it will take far longer than people think to fill and freeze the Earth's oceans. The total volume of water in the Earth's oceans is about kilograms, and freezing all of them requires at least about joules of heat to be dissipated. The Earth dissipates heat at a rate of about joules per second under ideal conditions where the surface temperature is all 0 degrees Celsius, a number that shrinks further after the top of the ocean freezes.

It doesn't need to be too precise, considering that about 70% of the surface of the ocean is continuously dissipated at 70% of the above rate, it would take more than 129 years to freeze most of it. Liquid water on the ocean floor near the upper mantle may not freeze for billions of years.

If the world changes to Kai Leng, it will also change the world a lot, and some animals and plants will also be affected and become extinct. According to scientists' analysis, around 2050, the Earth will usher in a new "Xiaoice Age", when the global temperature is likely to drop dramatically, and energy will also decrease. Scientists have found in their study of sunspots that the situation of solar activity is changing, and we all know that solar activity is closely related to sunspots and affects each other.

Scientists have found that solar activity is decreasing in recent years, which means that the number of sunspots is also declining, and it is likely to disappear, perhaps after a period of time, the Earth will really enter the "Xiaoice Period" like scientists.

Just like in "The Wandering Earth", the global climate has changed suddenly, many animals and plants have lost their lives because they can't adapt, crops will also be greatly affected, and human beings are likely to have conflicts over food and clothing.

Climate change on the earth does not have a unidirectional manifestation of getting colder and warmer, but it is just a natural phenomenon of cooling or warming formed by the contrast of the temperature difference between the phases of the earth in climate change.

First, the climate and temperature changes of the earth are related to the orbit of the earth. The earth orbits around the third magnetic coil of the sun, is in the middle of the habitable zone of the solar system, is affected by the irradiation of the heat induction reaction of the solar thermal energy temperature difference, the temperature of the earth's orbit is about 0 degrees Celsius of the thermal induction reaction of the solar thermal energy temperature difference, and the space temperature region is between minus 80 and minus 80 degrees Celsius, which is a natural phenomenon with a very stable temperature in the space region.

Although the orbit of the earth is not a whole circle, but an elliptical state, it will cause the earth to produce a natural phenomenon of temperature difference change, and there will be a natural change in the climate of the four seasons, this change is a very stable situation, and will not cause the earth to have a large temperature difference change phenomenon. Therefore, the change in the Earth's climate does not occur in a unidirectional way that gets colder or warmer.

Second, the stability of the earth's temperature difference is related to the atmosphere and liquid water. The earth has a large atmosphere, which can ensure the role of the earth's hydrosphere circulation, protect the stability and naturalness of the earth's climate change in the four seasons, and also play the role of a shield against solar thermal radiation;

In addition, the earth's surface covers 70% of the liquid water (ocean), which stores the stable energy formed by solar thermal energy, effectively maintaining the regular natural temperature difference on the surface, and making the regular temperature of most of the earth's natural environment in the temperature difference range between 5 45 degrees Celsius. Therefore, both the atmosphere and the liquid water can play a role in neutralizing and balancing the surface temperature difference, and can maintain the natural stability of the surface temperature, so that there will be no unidirectional continuous cooling or continuous warming.

Third, the special changes in the earth's climate are related to volcanic eruptions. When the earth's volcanic eruption is at its peak, a large amount of volcanic ash (containing toxic chemicals) discharged from the crater will go straight to the sky, which can change the proportion of substances in the atmosphere and cause the density of particulate matter in the atmosphere to become more and more dense.

It often leads to occasional special changes in the earth's climate, such as heat waves, cold snaps, hurricanes, typhoons, hailstorms, heavy rains, floods, avalanches, landslides and haze, and the occurrence of occasional phased special changes in the surface climate. And the impact of human productivity is only insignificant.
