Greenhouse effect: causes, consequences, impact on climate and ways to solve the problem

One of the most urgent and discussed environmental problems is the greenhouse effect.

Hundreds of articles and scientific works are devoted to this phenomenon. According to scientists, it has a strong influence on the climate balance of the planet.

What is the greenhouse effect in the Earth’s atmosphere

Earth’s atmosphere has the ability to transmit the sun’s rays, while retaining thermal radiation from the surface. The result is heat accumulation. The accumulation of gases and other emissions in the atmosphere exacerbates this process, triggering the greenhouse effect mechanism.

This global problem has existed for a long time. But with the development of technologies that increase emissions into the atmosphere, with an increase in the number of cars and a general deterioration in the environment, it is becoming increasingly relevant. According to statistics, the average temperature of the planet has increased by 0.74° over the past century alone. At first glance, this seems like quite a bit. But even such an increase has already led to irreversible climate change.

Who discovered the mechanism of the greenhouse effect? For the first time this definition was used in 1827 by J. Fourier. On this topic, he even wrote a voluminous article in which he considered various schemes for the formation of the earth’s climate. It was Fourier who first put forward and confirmed the idea that the optical properties of the earth’s atmosphere are similar to those of glass.

Later, the Swedish physicist Arrhenius, while studying the infrared properties of water vapor and carbon dioxide, put forward the theory that their accumulation in the atmosphere can cause an increase in the temperature of the entire planet. Subsequently, on the basis of these studies, the concept of the greenhouse effect arose.

What are greenhouse gases

Greenhouse gases is the collective name for a number of gases that can trap the planet’s thermal radiation. In the visible range, they remain transparent, while absorbing the infrared spectrum. There is no definite formula for greenhouse gases. Their percentage may change constantly. So what are greenhouse gases?

List of greenhouse gases

The main greenhouse gases are:

  1. Carbon dioxide. The longest living in the atmosphere, as a result of which it constantly accumulates.
  2. Methane. Due to a number of properties, it has a stronger activity. According to Wikipedia, its level in the atmosphere has increased by more than 150 times since 1750.
  3. Nitrous oxide
  4. Perfluorocarbons – PFCs.
  5. Hydrofluorocarbons (HFCs).
  6. Sulfur hexafluoride (SF6).

Ozone protects the planet from solar ultraviolet radiation. Its deficiency contributes to the formation of ozone holes.

Greenhouse effect

In addition to the main greenhouse gases, water vapor also increases the greenhouse effect in the atmosphere. In fact, it is the main reason for the increase in temperature and humidity.

In addition to the above, greenhouse gases include nitrogen oxides and freons. Due to active human activity, their concentration increases every year, which significantly exacerbates the negative impact on the environment.

Sources of greenhouse gases

Greenhouse gases lead to significant climate changes, by their nature, the sources of their formation can be divided into 2 large groups:

  1. Man-made. They are the main cause of the greenhouse effect. These include various industries that use the combustion of hydrocarbon fuels, the development of oil fields, emissions from automobile engines.
  2. Natural. They play a secondary role. Most of the natural greenhouse gases enter the atmosphere during volcanic eruptions. This group also includes the evaporation of the World Ocean and large forest fires.

Causes of the greenhouse effect

The main reason for the development of the greenhouse effect on Earth are gases accumulating in the atmosphere. Exceeding their concentration leads to a change in the heat balance. Additionally, the ozone layer can also be involved in this process. Under the influence of freon and nitrogen oxides, which are also included in the list of greenhouse gases, it begins to rapidly break down and become thinner. As a result, the level of hard ultraviolet radiation increases dramatically. Thus, the greenhouse effect and the destruction of the ozone layer are a chain of interrelated events that have a significant impact on the biogeocenosis of the entire planet.

The main causes of the greenhouse effect include:

  1. The rapid growth of industry using oil, gas and other fossil hydrocarbons as energy sources. They account for about half of all gas emissions.
  2. Massive deforestation. In the process of photosynthesis, trees absorb carbon dioxide and produce oxygen, forests are the “lungs of the planet”, their destruction is fraught with a sharp increase in the amount of carbon dioxide in the atmosphere.
  3. Development of agriculture. As a result of the decay of animal waste products, a large amount of methane is produced, which is one of the most aggressive greenhouse gases.

What increases the greenhouse effect

In addition to human activities, natural causes can also contribute to the enhancement of the greenhouse effect.

Greenhouse effect

For example, large volcanic eruptions or mass burning of forests. An increase in temperature on the Earth’s surface as a result of the thinning of the ozone layer leads to increased evaporation of moisture, which also aggravates the situation. The relationship between the greenhouse effect and the ozone layer has long been proven. An increase in the concentration of water vapor in the atmosphere is a fundamental factor in the development of the problem.

Consequences of the greenhouse effect

The consequences, as well as the causes of the greenhouse effect, are very diverse. Its influence on the climate is especially strong. In simple terms, greenhouse gas emissions can lead to a number of significant changes:

  1. Decrease or increase in precipitation. In a number of climatic zones, rains will become more rare, while others, on the contrary, will suffer from constant storms and flooding.
  2. Rising sea levels. This will be one of the most significant consequences of the greenhouse effect. As a result of the melting of the ice of Antarctica and Greenland, large areas will be flooded, which will destroy all coastal settlements. At the same time, it should be noted that a significant part of the population lives in them, which will be without housing and livelihoods.
  3. Death of entire ecosystems. In short, the greenhouse effect will cause significant climate change. As a result, many biological species will not be able to adapt to rapidly changing conditions and will simply die. Their disappearance from the food chain will lead to a “domino effect”.

Climate change will also affect human health. Due to abnormally high temperatures, the number of heart, lung and respiratory diseases will increase significantly. Therefore, there is no benefit from the greenhouse effect, but the harm is very significant.

Map of greenhouse gas emissions

For a more complete picture of the scale and nature of the greenhouse effect, Google developed a map of greenhouse gas emissions in 2012, which shows which places on Earth have the most of them. It displays the emission levels of all industrialized countries using color coding. The creation of the map was timed to coincide with the end of the Kyoto Protocol.

Help: What is the Kyoto Protocol and what is its essence? Briefly, this is an international agreement that was concluded to reduce greenhouse gas emissions into the planet’s atmosphere in order to prevent or reduce the effect of global warming. The Kyoto Protocol is an additional document to the 1992 United Nations Framework Convention on Climate Change (UNFCCC). Why “Kyoto”? This protocol was adopted in the Japanese city of Kyoto on December 11, 1997 and entered into force on February 16, 2005. The main goal of the agreement received between the countries is to stabilize the level of concentration of greenhouse gases in the atmosphere at a level that would not allow dangerous anthropogenic impact on the Earth’s climate system. Now there are 192 parties to the Kyoto Protocol (191 states and the European Union). At the same time, the United States signed but did not ratify the Protocol, Canada officially withdrew from the Kyoto Protocol on December 16, 2012.

Measures to prevent and reduce the greenhouse effect

Changes in the climate on Earth have already occurred repeatedly. In short, their consequences were catastrophic. An example is the well-known Ice Age. Its influence on living organisms was very significant. Some species simply died out, never adapting to a sharp cold snap. Remains of ice from that time are still preserved in Antarctica and Greenland.

What needs to be done to reduce the greenhouse effect and prevent another cataclysm? How to deal effectively with a global problem? At the moment, all the factors contributing to the accumulation of gases in the atmosphere have already been identified. According to experts studying the physical foundations of the greenhouse effect, there are several ways to solve this problem:

  1. Reduce emissions of harmful substances from industrial activities.
  2. Actively introduce environmentally friendly technologies using alternative energy sources. This will allow us to refuse or at least minimize the consumption of fuel hydrocarbons.
  3. Stop active deforestation.
  4. The elimination of natural landfills also contributes to the reduction of greenhouse gas emissions into the atmosphere, because they are the source of methane, freon and nitrogen oxides.

There are various ways to solve the problem of the greenhouse effect. The main thing is that the struggle should be conducted at the international level. To correct the current situation, the efforts of all mankind are needed. Gas emissions are a global problem, it concerns the entire planet as a whole, and not individual countries.
