Global warming


Glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is struggling to keep up day by day. It’s clear that humans have caused most of the warming of the past century by releasing heat- trapping gases as we power our modern lives. These gases are known as greenhouse gases and their levels are higher now than in the last 650,000 years. The result of this we know by the name of global warming , which is generating a set of negative changes on Earth’s climate, or on different long-term weather patterns , which vary from place to place. As the Earth rotates each day, more heat swirls with it, gathering moisture over the oceans, changing the rhythms of the weather that all living things have previously enjoyed.


What is global warming?

Global warming is the result of the warming of the planet due to the emission of gases which have the ability to retain heat, these gases are known as gases of gases and their levels rise increasingly.

What does it consist of

Warming consists of a phenomenon that produces an increase in the global average temperature of the earth’s atmosphere and the oceans . This increase in temperature has worsened in the last decades of the 20th century and the first of the 21st.


It is associated with climate change , for anthropogenic reasons or not. The main effect caused by global warming is the greenhouse effect , which involves the absorption by means of certain atmospheric gases , mainly carbon dioxide, part of the energy that the soil emits as a result of heating by solar radiation .

How global warming occurs

Global warming occurs when carbon dioxide and other pollutants found in the air accumulate in the atmosphere and thus form an increasingly thick layer. In this layer, more heat from the Sun is trapped, resulting in our planet getting hotter and hotter, suffering the same effect that would occur in a greenhouse .

The main source of emission of carbon dioxide generated by human activity is the plant generating power based on coal . The release of methane gas on the planet, mainly the one that occurs in the arctic tundra and swamps , is also caused by nature and is another reason for global warming.


The main characteristics of global warming are the following:

  • It is closely related to human activities .
  • The greenhouse effect is the main cause of global warming.
  • There is an increase in temperature in some parts of the plane.
  • There is a greater number of droughts .
  • The north pole is gradually thawing .


According to scientists and experts consider this phenomenon has been slowly causing the increase of the temperature of the planet and according to a series of investigations, the process began with the Industrial Revolution , and when they began to see the first consequences started talking of global warming.

According to UN research , the 20th century was the hottest in the last five years, and for many years world average temperatures increased between 0.3 and 0.6 ° C. Although it may seem like an insignificant number, This variation in temperature can affect the living conditions of an ecosystem as a whole.

Causes of global warming

Among the main causes of global warming we can mention the following:

  • Increase in solar activity that negatively influences the health of the planet.
  • Increase in water vapor in the atmosphere causing the average temperature to increase from time to time, which contributes little by little to warming.
  • Climatic cycles that the planet goes through regularly caused by the sun.
  • Greenhouse gases caused by human action.
  • Emission of carbon dioxide which is a danger and threat to the life of the planet.
  • Burning of fossil fuels caused by the production of electricity and the gasoline used by cars on a daily basis.
  • The deforestation of the planet’s forests, which increases the amount of carbon dioxide in the entire atmosphere.
  • Higher concentrations of CO2 in the atmosphere, which leads to an increase in global warming and therefore a greater rise in temperatures.

Effects edit

Some of the effects that can already be observed worldwide and that are direct effects of global warming are:

  • Melting ice on the mountainous poles and glaciers of Antarctica and Greenland.
  • Decrease in the number of Adélie penguins in Antarctica.
  • Rise in sea ​​level .
  • Some animals have moved north or looking for colder areas to live.
  • The rainfall has increased worldwide.
  • Sea level is expected to rise between 18 and 59 centimeters by the end of this century.
  • The hurricanes and storms are becoming harder causing more destruction.
  • The floods and droughts will become more frequent if global warming continues.
  • We will have less drinking water
  • The disease transmitted mainly by mosquitoes will be transmitted more frequently.
  • There will be changes in ecosystems and some animals could become extinct .


Among the consequences that most concern experts we can mention:

  • The accumulation of polluting gases causes temperatures to rise more and more causing heat waves .
  • The storms , floods and hurricanes will be more powerful.
  • More diseases will spread .
  • Melting of glaciers raising sea level.
  • Serious changes in ecosystems .
  • Disappearance of animal and plant species .

How to prevent global warming

To prevent global warming it is important first to make the world population aware of the risk that is run. People should seek alternative measures to produce energy other than fossil fuels , as these generate large amounts of carbon dioxide.

Reforesting forests is extremely important as trees help control the carbon dioxide in the atmosphere. Used cars for bio- fuel , it is an encouraging option to alleviate global warming, using bicycle or walking , are alternative measures to prevent the problem.

Change the bulbs to CFL that produce lower energy consumption reducing electricity consumption. Replace appliances that have finished their useful life, use of solar panels and power generators .

What gases produce global warming

The gases responsible for global warming are the following:

  • Carbon dioxide
  • Methane
  • Nitrous oxide
  • Sulfur hexafluoride
  • Chlorofluorocarbons
  • Water steam
  • Carbon dioxide and air pollutants


The issue of global warming is a very important phenomenon, because we must be aware of what is happening around us, since the main problem is the lack of awareness of the population, which continues to cause pollution of the environment . It is important to carry out information and awareness campaigns , to prevent our planet from suffering the serious consequences that global warming entails.


Some examples of global warming that we can observe worldwide are:

  • Increase in droughts as already occurs in different parts of the world such as Africa and places such as the western United States .
  • The coral reefs are in decline due to global warming.
  • In cities like Beijing , there are already maximum alerts at airports and land roads due to the large amount of smog in the air, affecting people’s airways and the visibility of drivers.
