Essay on global warming and climate change, essay on global warming and climate change in hindi (100 words)

The entire climate of the world is changing regularly due to increasing global warming by natural means and human activities . All changes have a great impact on people’s lives and ecosystems. Average global temperature has risen by 1 degree in the last 30 years.

It has been reported by the Intergovernmental Panel on Climate Change (IPCC) that the average global temperature can rise from 2 to 8.6 degrees F by 2100. The reason for the increase in global temperature is the increased emissions of heat-trapping gases into the atmosphere as greenhouses.

Essay on global warming and climate change, 150 words:

Climate change on Earth is partly caused by the natural cycles of the Earth but currently human activities are still the major source of climate change. Rising levels of greenhouse gases, including carbon dioxide, bring more heat to Earth because they have the ability to absorb and emit heat into the atmosphere and thus keep the Earth warmer.

Some dangerous human activities such as burning fossil fuels, deforestation, technological inventions, etc., are adding more toxic greenhouse gases to the atmosphere. All greenhouse gases cause the temperature of the earth to rise at a high rate which is not in favor of human, animal and plant life.

A greater level of climate change disrupts the balance of the global ecosystem as well as increasing health risks and greater heat-related injuries and deaths. Rising sea levels are also an example of climate change caused by global warming which in turn causes floods, droughts, and increases the risk of malaria and other parasites.

There are many causes of climate change including the natural cycle of the Earth, although the major contribution of climate change is global warming. Many human activities and technological developments in the world are forcing greenhouse gases to rise and collect in the atmosphere which in turn makes the Earth warmer and warmer by increasing the temperature of the environment in a faster and easier way.

Other climate changes such as sea water levels cause floods that give rise to malaria and other parasites, increase coastal erosion, destroy people’s homes in coastal states and many more.

High temperatures cause problems for the existence of life on this planet, even many important species of plants and animals are endangered. Long and severe heat waves of the environment increase the rate of evaporation of water from small water bodies due to more heat-related injuries and higher atmospheric temperatures.

Constantly rising temperatures have different effects in different areas such as in some areas it raises the water level and in some areas it lowers the water level. The availability of sweet water is decreasing all over the world which is an important resource of life on this planet. In such a warm climate, some crops are very difficult to grow, corn production may be reduced by 10 to 30% if the temperature rises to 3.6 degrees Fahrenheit.

Climate change has become more prominent due to global warming which is a global concern. Both are hot issues of current times and it is time to analyze the causes and methods of prevention to prevent global warming.

The release of various greenhouse gases into the atmosphere by many natural means and causes an increase in atmospheric temperature because such gases have the ability to absorb all the heat of the environment from the sun, burning coal, etc. Such gases from the sun’s rays. Never let go and it returns to the atmosphere causing a heat trap and an increase in temperature is experienced.

Rise in sea level rise due to increase in atmospheric temperature, flood, drought, change in weather, increase in summer season, decrease in winter season, melting of glaciers, increase in mortality, increase in disease numbers, decline in ozone layer And others cause so many climate changes such as climate change.

Burning fossil fuels releases more carbon dioxide which is increasing day by day due to deforestation. Plants are the main source for using carbon dioxide as a food, although we are disturbing the natural cycle by cutting more plants.

Burning of coal, oil and natural gases is the main cause of global warming. CO2 gas acts as a blanket that retains environmental heat and heats the Earth’s surface. Over the last century, carbon dioxide levels have risen to a great level. The Earth’s surface has become progressively warmer than before in the last three decades. Each month is getting warmer than before which we can feel very clearly. This rising heat has affected the lives of humans, plants and animals and even many species.

There are many reasons behind climate change, some are natural and some are human activities. Climate change is not a region or region, it is changing all over the world. Climate change occurs when atmospheric temperatures rise too high which in turn causes many different changes on Earth such as more floods, intense rainfall, droughts, more frequent and severe heat wave rate increases, oceans Levels rise, glaciers melt, warm, sea water is becoming more acidic, and many more. All these changes can happen more rapidly in future decades and can challenge the society and environment immensely.

Over the last few centuries, human activities have increased the release of large amounts of carbon dioxide, including other greenhouse gases, into the atmosphere. Most greenhouse gases come from burning fossil fuels that act as blankets around the Earth and trap all the energy and heat available in the atmosphere and thus heat the Earth’s surface.

This effect is called the greenhouse effect, which alters the climate to enormous levels and results in dangerous impacts to life and ecosystems. Such hot climate affects the availability of natural water supply, crop production, agriculture, natural environment, safety, security etc. Such massive climate change is inevitable but cannot be stopped at once.

Global warming has indeed affected and forced climate change over the last century worldwide. The unusual increase in the Earth’s average temperature is because burning of fossil fuels and other human activities releases high amounts of greenhouse gases. Some of the greenhouse gases that have a greater impact on the climate are CO2, water vapor, dinitrogen-oxide, and methane.

According to research, it has been recorded that about 30 percent of the heat from incoming sunlight returns to space through clouds and snow but the ice is melting due to global warming. This means that there are no sources to send heat back into space and all are gathering in the Earth’s atmosphere and affecting the climate.

At present, a huge level of climate change attracts people’s attention very easily. Each one of us is feeling very clearly from short-term changes in the changing seasons of temperature, drought, rain without weather, changing patterns of weather, etc., causing long-term changes affecting the whole earth.

Climate is a long-term weather trend that positively or negatively affects human life. Climate change is a long-term change in weather. The climate has been going the wrong way from time to time for many years, as huge sheets of ice are being destroyed regularly.

The Earth’s atmosphere was previously covered with sheets of ice that were able to protect the Earth from heat and cool the Earth’s atmosphere by sending excess heat from the Earth into space. In a cyclical way, the climate has changed from cooler to warmer in the last two million years. The Sun is the ultimate source of heat energy that fuels the weather systems after reaching Earth.

Earlier the harsh and extended bitter cold weather was called the Lesser Ice Age, which was due to large-scale changes in solar activity. It has been found that positive human activities can play a major role in shaping the Earth’s climate.

Such a big change in climate can threaten human life. It was previously believed that the change in climatic pattern from the ice age to the warm period is due to time, but later it was conceived that this is due to the regular melting of ice sheets over one kilometer in thickness. . Our climate is rapidly warming at a rate of about 8 ° C in 10 years.

A major industrial revolution in modern times has affected the global climate system to a great extent by increasing the amount of greenhouse gases in the Earth’s atmosphere. Heat trapping nature of greenhouse gases contributes to global warming. According to the Intergovernmental Panel on Climate Change (IPCC), the increase in the average surface temperature of the Earth has been around 0.6 ° C until the 20th century.

Over the last century, the Northern Hemisphere has also recorded a 10 percent decrease in snow cover, a 10-15 percent decrease in sea ice in spring and summer, an increase in rainfall and its intensity, a change in the heavy level in Pali The ice freezes and breaks into rivers and lakes.

Essay on global warming and climate change, 800 words:

Preface:

Global warming refers to an increase in the Earth’s average temperature. Climate change, on the other hand, is one of the most important consequences of global warming. Although, global warming and climate change are often used interchangeably, they differ from each other. In the following essay, we will study global warming and climate change in detail.

What is the global temperature?

Global warming refers to the long-term warming of the planet since the Industrial Revolution in the 1970s. Since then, the Earth’s average temperature has risen slightly above 1 ° C, a change that may seem small, but even small changes in Earth’s temperature can have detrimental effects and the temperature is still rising slowly.

What is climate change?

Climate change is an implication of global warming. In addition to the unforeseen changes of weather as a result of global warming, glaciers suffer other effects such as melting, sea temperature and extreme cold or heat. All these conditions cause changes in climatic conditions all over the world.

What are the causes of global warming?

One of the main causes of global warming is an increased greenhouse effect. This is due to the atmospheric state of greenhouse gases such as carbon dioxide (CO2), carbon monoxide (CO) and methane (CH4). These gases are emitted as a by-product of the production and use of fossil fuels. Humans use fossil fuels extensively, resulting in increased atmospheric concentration of greenhouse gases, resulting in a greenhouse effect.

To understand global warming, let us understand the green house effect. Under ideal conditions, the Earth’s atmosphere contains many gases including the amount of greenhouse gases. During the hours of sunlight, these gases filter the sun’s UV rays and also the intensity of the sun’s rays. At night, these gases help the Earth to retain the heat absorbed during the day, which prevents it from entering the atmosphere, thereby maintaining the Earth’s temperature.

Human activities such as industrialization and widespread use of fossil fuels result in the production of greenhouse gases (pre-CO2, CH4, CO etc.), and therefore a large greenhouse effect. To better understand the greenhouse effect, imagine sitting inside the car on a sunny day, with its windows opened. The rays of the sun will reach the inside of the car through the glass of the window, but since the car is completely closed, they are unable to return to the atmosphere, thus raising the internal temperature of the car further. This phenomenon is called the greenhouse effect, and forms the basis of global warming.

What are the causes of climate change?

The greenhouse effect, as noted above, is mainly attributed to climate change. The heat of the Sun prevents the Earth’s surface from escaping some gases that form a thermal blanket on the Earth. These gases mainly form water vapor (H2O) and other gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), and allow the Earth’s temperature for life to support 15 ° C. Are responsible for maintaining.

These gases are called greenhouse gases. The problem arises when the atmospheric concentration of greenhouse gases rises above the permissible level. Human activities, such as industrialization and excessive use of fossil fuels, produce greenhouse gases.

This increased the concentration of greenhouse gases in the atmosphere, increased the greenhouse effect, which resulted in the average temperature of the earth moving above 15 ° C. The temperature rise in the Earth’s atmospheric and surface temperatures leads to some unexpected and drastic changes in climatic conditions, which is triggered by a series of events arising due to the temperature rise.

For example, the temperature rise results in melting of the Earth’s ice cover, which is present as glaciers and snow fall. This additional melting of ice leads to an increase in temperature and other climatic conditions. An increase in the Earth’s average temperature also changes the monsoon currents, resulting in less rainfall in some areas for the last few decades. South Asia has recorded significantly less rainfall during the past four decades, while rainfall has increased in abundance in the tropical western Pacific.

In addition, an increase in the Earth’s temperature results in natural disasters such as floods, famines, droughts and hurricanes. Many cyclones and storms worldwide have been attributed to greenhouse gases and a raised greenhouse effect.

Conclusion:

Climate change is a consequence of global warming, and on the other hand the latter is caused by human activities. The greenhouse effect is responsible for maintaining the Earth’s average temperature up to 15 ° C, but in recent decades, the greenhouse effect has increased, as man-made greenhouse gases have increased. With the increase of the greenhouse effect, sudden climate change becomes inevitable worldwide, often resulting in extreme events such as famine, drought, flooding and cyclones.

Both global warming and climate change are directly linked to human activities and only humans have the power to mitigate or mitigate impacts. Therefore, it is necessary to take appropriate steps in this regard and to protect the planet from the consequences of global warming and climate change.
