Global Warming Definition: What is the definition of global warming?

Global warming is a term used to describe the increase in average temperature of the Earth’s atmosphere and oceans. The warming of the earth’s climate system is considered to be a direct consequence of increasing concentrations of greenhouse gases (like carbon dioxide, methane and other pollutants) in the atmosphere, caused by human activities.

What exactly is global warming?

Global warming is a problem that threatens our planet. It has become a major concern because it is affecting the world's climate. The main cause of global warming is the burning of fossil fuels such as coal, oil, and natural gas. These fuels are used to create electricity and heat homes and businesses. The burning of these fuels causes the release of carbon dioxide, methane, nitrous oxide, and other gases that trap heat in the atmosphere. This traps heat on Earth causing the surface to get warmer.

What Are The Causes of Global Warming?

There are two primary causes of global warming, according to the National Oceanic and Atmospheric Administration (NOAA). The first is the greenhouse effect, in which carbon dioxide from the atmosphere is absorbed by plants and other living things. This process makes the Earth's temperature rise. The second is the melting of ice sheets in Greenland and Antarctica, which are thought to be the main contributors to sea level rise. These factors have a number of contributing factors.

What are Man-made Causes of Global Warming?


Plants take in carbon dioxide and release oxygen, thereby maintaining environmental balance. Forests are being cut down for many domestic and commercial purposes. This has led to a reduction in the CO2 that the remove from our atmosphere, thereby giving rise to climate change.


The use of vehicles results in various emissions. Vehicles burn fossil fuels that emit carbon dioxide and other toxins into the atmosphere which causes a temperature increase.


The ozone layer protects us from harmful rays from the sun, so when we use CFCs in the environment, the ozone layer becomes thinner.

The ozone layer protects the earth from the harmful ultraviolet rays of the sun.

Because of ozone depletion, the temperature of the earth has increased, causing the climate change. The climate change leads to an increase in temperature, which in turn leads to higher ozone layer.


Industrialization led to an increase in temperatures, and we are now warming up due to climate change.

The rising temperature of the earth is caused by the pollution from the factories.

According to the Intergovernmental Panel for Climate Change, between 1880 and 2012, the global temperature increased by 1 degree Celsius.

The increase in temperatures is 1.1 degrees Celsius when compared to the pre-industrial mean temperature.


Carbon dioxide and methane gas are produced by farming. The greenhouse gases add to the atmosphere and increase the temperature.

The increase in global temperatures is resulting in loss of crop yields, destruction of natural ecosystems, more frequent floods and droughts, and increased frequency and severity of forest fires. The U.S. Environmental Protection Agency (EPA) estimates that agricultural activities are responsible for approximately 17 percent of all man-made greenhouse gases. The EPA estimates that about 4 billion metric tons of carbon dioxide is emitted annually from fossil fuels used for agricultural purposes in the United States.


The increase in population means more people emitting CO2 through their daily activities. This leads to an increase in the level of carbon dioxide, the primary gas causing global warming, in the atmosphere.

More CO2 means more heat and therefore more humidity.

How much does human activity contribute to global warming? In the past hundred years, the average temperature has increased by about 1°C (1.8°F). This is mainly due to human activity, which is causing increasing concentrations of carbon dioxide in the atmosphere.

Temperatures have increased at a higher rate than any other time in history.

What are the Natural Causes of Global Warming?


Volcano are one of the largest natural contributors to global warming. The ash and smoke released by volcanoes affects the global climate.

Water Vapor

Water vapor is also a greenhouse gas. As the temperature increases, more water evaporates from lakes and oceans and enters the atmosphere which adds to global warming.

Melting Permafrost

It has been found that in the Arctic, the melting of permafrost is contributing to the rise of global temperatures. Scientists have discovered that there is a correlation between the melting of permafrost and the increase of Earth’s temperature. They have also found that the melting of permafrost is linked to the greenhouse gas, carbon dioxide. The release of the greenhouse gases into the atmosphere leads to the increase of global temperatures. In fact, scientists have calculated that if permafrost were to melt completely, then the average temperature on Earth would rise by about 4 degrees Celsius. This would cause the glaciers to disappear and oceans to become warmer.

Forest Fires

Forest fires are well known for the huge amount of carbon-containing smoke they emit. This smoke triggers the greenhouse effect and raises our planet's temperature.

What Are The Effects of Global Warming?

These are the major, harmful effects of global warming:

A Rise in Temperature

The Earth has experienced an overall warming trend since 1880. The Earth’s average surface temperature has increased by about 1.1°C since 1880, largely due to the increased emission of greenhouse gases. The melting of glaciers has led to an increase in the sea level. This could have devastating effects on coastal regions.

Harm To Our Ecosystem

Global warming has caused the coral reefs to become more fragile, which can lead to the loss of plant and animal life. Additionally, the increase in global temperatures has made the fragility of coral reefs even worse.

Climate Change

Global warming has led to a change in our climate. It has affected the production of food, water supplies, and human health. As a result, people have been forced to move from their homes. They have been displaced by the climate change. Many have become refugees.

Outbreaks Of Disease

Global warming leads to changes in the patterns of heat and humidity. This has led to the rise of malaria and West Nile virus that are very dangerous to humans. These diseases can cause death and leave a person with lasting health problems.

Increasing Mortality Rates

The death toll increases when there is an increase in floods, earthquakes, and other natural disasters. The spread of diseases that can hamper human life can be brought about by events like this caused by global warming.

Destruction of Natural Habitat

The loss of habitats of several plants and animals is caused by a global shift in the climate. In this case, the animals need to migrate from their natural habitat and many of them become extinct. This is one of the major impacts of global warming on the environment.

Frequently Asked Questions

These are the most frequently asked questions about global warming and climate change:

What exactly is global warming?

Is it just a natural cycle that has been going on for thousands of years, or is it caused by human activity and therefore needs to be stopped? What does the scientific evidence say? Are there any good reasons not to believe in global warming? Global Warming is the increase in the Earth’s temperature over the last century. This is most likely due to the increased amount of Green House Gases (GHG) emitted into the atmosphere.

What role do CFCs play in global warming?

The question of whether or not the use of CFCs is a major contributor to global warming has been hotly debated for some time. The use of CFCs has been linked to ozone depletion, as well as to increased levels of greenhouse gases. In the late 1980s, the Montreal Protocol was signed, which banned the production and use of certain CFCs, such as CFC-11, and other hydrofluorocarbons.

Does global warming impact climate change?

Global warming is to blame for causing climate change. Burning fossil fuels and cutting down trees are things that cause the temperature on the Earth to increase. Dry areas get wet and wet areas get dry when the weather patterns change because of high temperature. This results in increasing the number of disasters like floods, droughts, and so on.

Can we stop global warming?

Yes, it is possible to stop global warming by setting a high price of carbon, increasing the production from organic waste, using renewable energy like solar and wind power, and improving the energy efficiency and vehicle fuel economy.


In conclusion, the term “global warming” was first used by Svante Arrhenius in 1896 to refer to the heating of the Earth’s surface, but now it refers to any change in the earth’s climate caused by increased concentrations of greenhouse gases in the atmosphere. The increase in carbon dioxide concentration in the atmosphere is due to human activity, especially burning fossil fuels.
