The XNUMXst century is being the century in which both the climate change as global warming have become two real threats for the entire planet. In the case of global warming, the same is caused by Increase in medium temperature of the oceans and the atmosphere due to natural causes and mainly as a consequence of the human action.
Each filtering bag scientists and experts In the field, they have spent several decades studying this phenomenon and trying to predict the changes that this warming will cause all over the planet in a few years and if there is still time to stop such devastating effects that threaten to shorten the natural life of Earth. Then I will comment in more detail and to make it clear to you, what are the causes of global warming and its possible consequences in the medium and long term.

Natural causes of global warming
According to the vast majority of climate change scholars, some of the causes of global warming of the planet may well be due to natural causes or artificial causes caused by the human being's own action. In the case of natural causes, have been contributing to the global warming of the planet for thousands and thousands of years. However, these types of causes are not important enough to give rise to the climate changes that the entire planet is suffering today and that they are causing a serious threat to the entire world.
One of the natural causes of global warming more important and that is having a negative impact on the health of the planet itself, is due to a large increase in solar activity causing short-term heating cycles. Our sun is getting bigger and bigger and, therefore, it also generates more solar radiation during its nuclear fusion activity. We know that harmful solar rays are deflected thanks to the ozone layer and the Earth's magnetic field. However, they contribute to climate change, since part of this radiation remains in the atmosphere stored in the form of heat and increases the average temperatures of the planet.
Another type of natural cause that is causing said global warming is the increase in steam in the atmosphere, which causes the average temperature to increase from time to time and contributes to the warming itself. Water vapor is a greenhouse gas that is able to naturally retain heat. It contributes to the natural greenhouse effect and it is thanks to the water vapor that we can survive in these pleasant temperatures for the formation of life.
The problem is when humans modify this part of the water cycle and generate more water vapor. You could say that this is one of the causes of global warming that looks both artificial and natural at the same time. The greater the amount of atmospheric water vapor, the greater the retention of heat.
A third natural cause of global warming is due to so-called climatic cycles that usually cross the planet on a regular basis. These cycles must be to the sun's rays of the star king. In this way, if the Sun is the source of energy what drives the earth's climate, it is logical that the solar radiation itself has a predominant role in the temperature changes that the entire planet is undergoing.
Man-made causes of global warming
Although natural causes play a predominant role in global warming of the planet, they are the artificial causes of global warming the ones that are causing the most devastation on Earth. Most man-made causes are the result of increased called greenhouse gases caused by the action of man. This greenhouse effect is caused by the emission of carbon dioxide and it is the most important cause of global warming today. This type of emission has become a real danger and threat for the life of the planet and that is why most experts seek immediate solutions to beat such devastating effects.
Increase in greenhouse gas emissions
These carbon dioxide emissions are the result of burning fossil fuels. AND is that most of this burning is caused by the production of electricity and by the gas who use cars every day on the roads of the world. As the years go by and the Earth's population increases, more and more will be burned. fossil fuels, negatively impacting the environment and global warming, reaching a time when the temperature is quite high causing serious problems in the entire world population.
We must understand atmospheric dynamics as something that continually fluctuates due to the concentration of various gases present in the atmosphere. Above all, with CO2, the balance is not always the same, since there are many living beings that carry out photosynthesis and use this gas to survive.
Another man-made causes of global warming is deforestation of many of the planet's forests, causing carbon dioxide to rise throughout the atmosphere. Trees convert CO2 into oxygen through photosynthesis process and the own deforestation reduces the number of trees available to convert CO2 into oxygen. The result of this is a greater CO2 concentration in the atmosphere, which leads to an increase in global warming and therefore a greater rise in temperatures.
Deforestation also brings with it a decrease in biodiversity due to the fragmentation and destruction of the natural habitats of many species. The rate of deforestation does not stop and it is expected that by 2050 more than half of the Amazon rainforest will have been devastated.
El overuse of fertilizers in agriculture is one of the most important causes of the excessive increase in the average temperature of the planet. These fertilizers contain high levels of nitrogen oxides, much more harmful than carbon dioxide itself. As the population grows and increases, there is a increased need for food, so there is an increase in cultivated fields and therefore, a greater use of fertilizers in them.
The production and supply of food at a global level requires rapid harvests that translates into the indiscriminate use of fertilizers, herbicides, pesticides, fungicides and everything related to optimizing the growth and development of crops. It is necessary to think long term and start consuming local products that do not need as many fertilizers and whose greenhouse gas emissions during transport are minimal.
One last cause to review of global warming and that must be taken into account is methane gas. This type of gas has a series of greenhouse effect properties much greater than CO2 itself. Methane is also produced through the decomposition of landfill waste and in everything related to the subject of manure. Organic matter in decomposition and in the absence of oxygen generates methane gas. This gas is also increasing in concentration and the power to store heat is enormous.
As you have seen and verified, they are numerous causes that cause global warming to increase and endanger the planet medium term. Although the causes of natural global warming have their incidence In such warming, it is man-made causes that are to solve in the shortest amount of time.
A few days ago it was possible to affirm that the year 2015 had been the hottest of all history on the entire planet. This really worrying fact coupled with the increasingly frequent extreme weather events hurricanes, tornadoes or cyclones should remove awareness from most of the world society to seek solutions as soon as possible.
Faced with this delicate situation, the governments of the great powers of the world must quickly take action and end climate change and global warming that the whole planet suffers every day.
What are the consequences of global warming?
The consequences of the increase in terrestrial temperatures affect the entire globe to a greater or lesser extent. For instance:
- In Spain it is being seen that heat waves are becoming more frequent, lasting and intense. Without going too far back in time, on August 14, 2021, the Cordovan city of Montoro beat its historical maximum, with 47,2ºC, during a heat wave episode that lasted several days.
- The rise in sea level will force us to change course at many points. For example, beaches could be lost, not to mention the threat it will pose to all those who live on the coast.
- Ecosystems will change. This in fact is something that is being seen: the plants that are more resistant to heat and droughts are replacing those that are less.
- Glaciers are melting, contributing to the rise in sea level.
- Animals quickly go extinct. Although here we could talk about poaching as well, there are many animals, such as polar bears that have increasingly difficult to catch their prey, as the ice melts before its time.
- Food could be more expensive. Plants depend on the climate to grow and also to produce their fruits, so that if conditions change, the more difficult it will be to get vegetables, cereals and / or vegetables.
As you can see, global warming is a very serious problem.
