As we all know, the problem of global warming has become a problem for all mankind.
The issue of warming has been mentioned countless times in the last decade, but we living in East Asia rarely feel the harm caused by this natural change, or even feel it is irrelevant.
In fact, we can often hear about the various dangers of global warming caused by the greenhouse effect in the news.
One of the most impressive things is the melting of the glaciers at both poles and the polar bears and many other land creatures. The phenomenon of plummeting populations after the birth went home difficult to hunt.
In fact, in addition to the poles being affected by warming, India, located in the interior of Asia near the equator, is also suffering great changes.
It is reported that India in 2021 and 2022 these two years, are "no spring year", in short, that is, in the supposedly comfortable spring March, India early into the more than thirty degrees of hot weather, which is equal to directly cross the spring to the summer state.
India is a hot and drought-prone region, very early in the summer temperatures have been approaching the threshold of the human body can withstand high temperatures.
Now, because of the effects of global warming, March days, which should be pleasant and comfortable, are disappearing, followed by layers of heat waves, making the inhabitants, animals and plants of India suffer.
Three years ago, a scholar from CNN predicted that if India's hot weather did not improve, much of the country would be unsuitable for human survival.
You know, India is also the world's most populous country, with a vast land, if India really becomes a barren land, it is also the loss of all mankind.
And to understand and solve the problem of high temperature in India, the first thing that should be tackled is the problem of global warming.
Global warming is not a new topic, but it is by far the most talked about climate issue in the world. There is no other reason for this, because the effects of warming are no longer limited to one region, but are gradually spreading all over the world.
The greenhouse effect has been a word of mouth for decades, and while many people do not understand its meaning, they know that it is not a mild term; rather, it is a double-edged sword, and its downsides are gradually overshadowing the benefits it brings.
To understand the greenhouse effect, we must first know the greenhouse gases that constitute it. The so-called greenhouse gases are some gases in the atmosphere that can absorb the long-wave radiation reflected from the ground and re-emit the radiation.
In short, greenhouse gases are gases that retain solar radiation on the earth and can heat indoor air temperatures.
We are most familiar with carbon dioxide as a greenhouse gas.
These greenhouse gases can be emitted in a variety of ways; fuel combustion and air conditioning and refrigeration are all ways to liberate carbon dioxide.
As these greenhouse gases are emitted, they gradually envelop the entire planet, thus creating the greenhouse effect. In the bailout of the greenhouse effect, the temperature of the earth's surface increases, thus triggering the problem of global warming.
At first glance, warming does not seem to be a bad thing, after all, in the perception of many people, the cold is the biggest threat to life, the high temperature is nothing.
However, the Earth's ecosystem is a typical butterfly effect, involving the whole body.
The planet we live on, after billions of years of development, has long formed its own ecosystem, and the balance of this ecosystem once disrupted will bring very serious consequences.
Even though the average temperature of the Earth has increased by less than one degree during these decades, this is not very significant or even negligible for people living in areas with distinct seasons.
However, it is important to know that the problem of melting glaciers and rising sea levels brought about by rising temperatures will eventually engulf all of humanity and even seriously threaten its survival.
This shows that warming is by no means a false proposition, we can not feel it as if we do not know, to know the community of human destiny, if we do not pay attention to, one day people will taste the bad consequences.
To this day, even though many countries are working hard to reduce the temperature of the earth, but still have not achieved very good results, in solving the problem of global warming, mankind still has a long way to go.
In fact, many scholars have realized that it is already impossible to avoid global warming, and it is already difficult to contain the annual increase in temperature, which is expected to rise by roughly 5 degrees Celsius on average by the end of this century.
And facing the dangers of global warming is much more than simply preventing sea level rise.
Because in addition to the obvious problems such as sea level rise, the extreme weather caused by the greenhouse effect is also a head-scratching presence.
The frequency of natural disasters such as tsunamis, hurricanes, and extreme heat waves will increase as temperatures increase.
These weather extremes have already been experienced by many countries, and the impact has far exceeded expectations, which also predicts that in the future, humans living in these areas will also suffer from different degrees of survival challenges.
Like India, it is a typical example.
Persistent heat and heat wave in India
India is the largest country in South Asia and has a vast land mass. Its unique topography and geographical location make much of India unusually hot due to its tropical monsoon climate.
Even though India as a whole is a country blessed with natural mineral resources, in reality it has become increasingly uninhabitable as global warming brings rising temperatures every year.
The heat has killed many Indians from pyrexia, a sudden illness that causes irreversible damage to the human nervous system, with symptoms similar to heatstroke but far more dangerous than heatstroke, and the mortality rate of pyrexia is known to be as high as eighty percent.
The Indian region is already famous for its high temperature, under the influence of the greenhouse effect, more intensified the surface temperature climbing, many areas in May, the temperature is nearly fifty degrees Celsius.
India as a large population, the gap between rich and poor, in addition to a small number of rich Indians can be exempt from outdoor work, most Indian residents in order to make a living are required to carry out long hours of outdoor work, the hot weather has become a major killer of the local.
Especially in the past two years, India from March onwards the temperature is as high as more than 30 degrees, should belong to the spring season but just become occupied by the three days.
The culprit for the increase in temperature in India in recent years is the heat wave as we know it.
A heat wave is when a stable high pressure system appears over an area and the air above it is pressed downward, which affects the convection of air.
Without air convection, there is no cloud formation, and without cloud formation, solar radiation can be directed unobstructed to the ground, making the surface temperature higher and higher.
This only lasts for a few days, causing a heat wave to form when the heat formed by solar radiation pools into a certain amount of energy.
Once a heat wave forms, then the area where that heat wave is located will be under its influence for many days in a row with hot weather.
Speaking of heat waves in fact, as Chinese we are not unfamiliar with the phenomenon of heat waves in several places in China this year, but extreme heat waves are indeed relatively rare.
And India has been hit by several extreme heat waves in the first half of this year, which has made the people living on it miserable.
Extreme heat waves, although there is no great direct threat to people, but the premise is that there are effective means of cooling, if it is a long time to work and live in a hot environment, it is very dangerous.
In addition, extreme heat waves affect crop production and reduce regional rainfall.
You know, India has always been a country with scarce water resources, although India has the existence of their "mother river", the Ganges.
But the Ganges water is besides the name "dead" water, can benefit not many people, and the Ganges water because of the lack of liquidity and full of filth, is not clean water.
About the extent of water shortage in India, we can get a glimpse from the Indian film "Water Wife", in which men living in arid areas usually marry another wife used to fetch water for the whole family, which is the water wife.
In the picture, a small water source, the flow of water is slow, less than a square meter, crowded with large and small water wives to fetch water, many water wives even spend a day can not get a drop of water, this is the status of India's extreme water shortage.
And the continued heat wave is not abundant water resources in India to add insult to injury, these in our eyes dispensable water, but their precious rain, water is the source of life, high temperature water shortage, for them is how cruel.
Extreme heat waves can hit a drought-stricken region as well as be deadly, but coupled with poor national conditions, it only adds to the misery.
Bad country conditions and unstoppable warming
When a country or region experiences extreme weather, the people who suffer the most are the ordinary people living in that land.
Under the continuous bombardment of heat, the bodies of ordinary people in India have almost reached the limit of what they can bear, and many people living at the bottom have not even been able to survive.
These ordinary people, there is no extra money to support the installation of cooling equipment to start, and there is no way to stop the work in hand to cool off at home to escape the heat.
In the 40 to 50 degree heat and lack of water, you can only go out and work hard to make money.
In such a reality, Indian officials should have stepped up to the plate to help these people, but unfortunately, India could not save all Indians from the baking heat, even if the whole country could.
The reason is simply that India's coal resources are in short supply.
You know, in this era of new energy has not been completely popular, most of the world's electricity is dependent on the burning of coal to be launched, especially in India, almost 70% of the electricity is powered by coal.
Today's coal shortage is a sign that India's power supply is in short supply.
The worst thing is that the price of coal has only increased in the last two years due to the impact of the epidemic and other international environmental factors, which is certainly another pressure on the status of India's power shortage.
For India's wealthy, energy shortages have no impact on their lives, and they can continue to enjoy the comfort of their indoor environment.
But for the ordinary people living in India and the lower class, it is an isolated and precarious situation. India is a country where the gap between the rich and the poor is extremely wide.
About the country of India, in addition to Indian movies, we can also see in many short videos about India.
Especially the videos about street food in India, "dirty" is synonymous with them. Although in China, the evaluation of roadside stalls is not only unclean and unhygienic, but compared with India's, our Chinese is very advanced.
In many videos, we can see that the production of Indian snacks around the stall there are many flies coiled, the ingredients are needless to say, not at all fresh, even the production of food cooking utensils are covered with a layer of dark dirt.
These food stalls are extremely common in India, but of course are limited to ordinary residential areas and slums, which also reflects the unclean drinking water of India's lower class and the willingness to be dirty in order to save what little water is available.
The heat brought to the people of India in addition to the physical sensation of heat and shortage of water resources, but also a significant reduction in crop yields.
India is also a country with a large agricultural system, many people rely on this farming to feed their families, and India's population base is huge, to feed such a large group of people, no abundant food is not possible.
The first half of the year of continuous high temperatures is the time when crops need irrigation, especially wheat, which is concentrated in the areas most affected by high temperatures, and its birth is seriously threatened.
Although it is not enough to make the Indian farmers harvest, but the reduction in production is the nail in the coffin, some experts expect India's food production this year by the impact of high temperatures will be reduced by about 15-25%.
India today can be said to be in dire straits under the heat, and the people at the bottom are the first to bear the brunt of the survival crisis, so it seems that the CNN experts predicted that India will no longer be suitable for human habitation is not a strange talk.
And water can carry the boat can also overturn the boat, so the development of India's upper class of comfortable life can not be maintained.
Everyone has a role to play in addressing climate issues
The current situation in India is actually a microcosm of the future of the entire human race in the face of climate warming, and no one is a winner in this climate crisis.
Although we can now watch the situation in India from a corner of the globe, if warming is not curbed early, extreme weather will eventually strike the world.
In recent years, China's extreme weather in large and small also appeared a lot, Henan floods hit the subway, sand and dust storms, etc., these look into the causes, are not unrelated to the climate problem.
Many people may already be aware of this problem, "low-carbon life" propaganda has also done everyone popular, once the plastic straws have been replaced with paper straws, the use of new energy vehicles increased, which is a good phenomenon.
Perhaps, warming is unstoppable, but if everyone can insist on reducing carbon emissions, buy time for scientists around the world to research countermeasures against warming, and accelerate the spread of new energy sources, then perhaps, everything can still be saved.
The power of people is strong, and as long as we are united, even the most difficult situations can be changed.
