Greenhouse Effects and Global Warming

In Earth’s atmosphere, there are many natural greenhouse effect gases. The cycle of water, carbon dioxide (CO2), and methane are some of the important parts that are in it. Without these greenhouse gases, life on Earth would not have happened. Like the planet Mars, Earth will also become very cold if there are no greenhouse-effect gases in its atmosphere. Conversely, if the amount of greenhouse gases continues to grow in the atmosphere, then The Earth’s temperature will continue to rise. Just think about which one you’re going to choose?

Although CO2, water cycles, and other greenhouse gases in the atmosphere are transparent to the Sun’s light radiation, they are still capable of capturing and absorbing large amounts of light radiation that radiates to Earth. Partially absorbed radiation will also be reflected back by Earth. Under normal circumstances, the amount of heat radiation absorbed by the reflected returns is the same.

Nowadays the higher air pollution causes the greenhouse effect to change. Often we listen to the term greenhouse effect, what exactly is the greenhouse effect? The greenhouse effect is a natural warming process that occurs when greenhouse gases in Earth’s atmosphere trap heat radiation from Earth.

The process, which is when the radiation of the Sun’s rays hits the surface of the Earth, will cause the Earth to become hot. Earth’s heat radiation will be emitted again into the atmosphere. The heat reflected by the Earth is blocked by air pollutants so that it is trapped and reflected Earth. This process will withstand some trapped heat then cause the Earth’s temperature to rise. As a result, the Earth remains warm and its temperature is increasing.

Understanding the Greenhouse Effect

greenhouse effects and global warming

The greenhouse effect is a natural warming process that occurs when certain gases in Earth’s atmosphere trap heat. The greenhouse gas allows the Sun’s light to enter the Earth, but it reflects it back to the surface of the Earth. Thus, conditions on Earth remain warm. Just like a house with walls made of glass.

Scientists have been studying the effects of greenhouses since 1824. Joseph Fourier stated that the Earth would be much colder if it did not have an atmosphere. The presence of greenhouse gases is what makes the Earth’s climate habitable. In the absence of a greenhouse effect, the surface of the Earth would change about 60 degrees F or 15.6 degrees C cooler.

Understanding Global Warming

Global warming is a term used to describe the gradual increase in the average temperature of Earth’s atmosphere and oceans, as well as a change believed to permanently change Earth’s climate.

Human activity always produces a variety of waste substances, one of which is gas. Most people think that the atmosphere can absorb these exhaust gases indefinitely and does not harm life. However, it is currently known that the number of exhaust gases can cause fundamental changes in the atmosphere as well as living conditions on Earth.

Various human activities such as the use of fossil fuels, logging, and burning of forests for the transfer of agricultural, residential, and industrial land will contribute CO2 to the atmosphere in large quantities. Over several periods, CO2 in the atmosphere increased by about 20%. Increased concentrations of greenhouse gases such as CO2 will affect heat levels on Earth. Much of the Sun’s radiation illuminates the Earth’s surface, then reflects into space.

Rising LEVELS of CO2 in the atmosphere over the past 150 years have concerned scientists because it is closely related to rising global temperatures. For more than a century, scientists have been studying how greenhouse gases warm the Earth and how the burning of fossil fuels contributes to the warming of Earth’s temperature. Most scientists believe that global warming has begun and will increase rapidly in this century. More than 100 years ago, the average temperature on Earth’s surface increased by about 0.6 degrees Celsius. This increase in temperature is called global warming. Global warming is a term used to describe the gradual increase in the average temperature of Earth’s atmosphere and oceans, as well as a change believed to permanently change Earth’s climate.

Causes of Global Warming

All forms of human activity always have an impact on the environment, whether it brings a positive impact or a negative impact. Similarly, the current condition of Earth’s atmosphere is changing due to human activity. Burning fossil fuels and logging can increase CO2 levels in the atmosphere. Because CO2 is one of the greenhouse gases, increasing CO2 levels in the atmosphere will contribute to global warming. Therefore, every year co2 levels in the atmosphere continuously increase. 

Some factors that cause global warming are as follows:

  1. CO2 emissions are derived from the burning of fossil fuels as power plants.
  2. CO2 emissions are derived from gasoline combustion as a means of transportation fuel.
  3. Methane emissions from animals, farmland, and the Arctic seabed.
  4. Deforestation is accompanied by the burning of forest land.
  5. Use of chlorofluorocarbons (CFCs) in refrigators (coolers).
  6. Increasing use of chemical fertilizers in agriculture.

The Impact of Global Warming

As has been stated before that human activity has altered the naturalness of greenhouse gases in the atmosphere. The consequences of changes in greenhouse gases in the atmosphere are difficult to predict, but some of the impacts that have been seen are as follows. 

Earth’s temperature is getting higher, in some regions it may be higher and in others may not.

The high temperature of the Earth may lead to more evaporation and overall rainfall, but each region will vary, some becoming wet and others dry.

Melting glaciers that cause seawater levels to increase. Similarly, the sloping coastal land, over time will experience an increase due to water disapplication.

The loss of coral reefs. A report on coral reefs stated that under the worst conditions, coral populations would disappear by 2100 due to rising temperatures and ocean acidification. As it is known that many other species whose live depends on coral reefs.

Widespread species extinction. According to research published in Nature magazine, rising temperatures could lead to the extinction of more than a million species. Until now the loss of species is expanding and the list of endangered species continues to grow and grow.

Massive crop failure. According to recent research, there is a 90% chance that 3 billion people worldwide will have to choose between going with their families to a climate of good climate or starvation due to climate change within 100 years.

Thinning of the ozone layer. The ozone layer is one of the atmospheric layers located within the stratosphere layer, which is about 17-25 km above the surface of the Earth. It is this layer that protects the Earth from the dangers of ultraviolet (UV) radiation. Based on satellite observations, it is known that the ozone layer has gradually thinned since the mid-1970. 

Efforts to Tackle Global Warming

The biggest cause of global warming is carbon dioxide (CO2) released when fossil fuels such as oil and coal are burned to produce energy. The large use of fossil fuels for the human activity will contribute to an increase in CO2 in the air.

Ozone layer damage is one example of the impact of human activity that disrupts the balance of ecosystems and biospheres. The high condition of pollutant gases in the air causes global warming.

Some efforts can be made to tackle global warming, including the following.

  1. Using renewable energy and reducing the use of coal, gasoline, wood, and other organic fuels.
  2. Improve vehicle fuel efficiency.
  3. Reduce deforestation.
  4. Reduce the use of products containing cholera fluorocarbons (CFCs) by using environmentally friendly products.
  5. Support and participate in green activities.

Research from Louisiana Tech University found that any green tree can capture enough carbon to offset emissions generated from motorists’ exhaust gases for a year.
