What Are the Known Causes of Global Warming?

By Rolf Joho

Gold Coast Tire & Auto About Causes of Global Warming

The causes of global warming is a serious issue in the world today and being aware of this causes is crucial. We have heard Al Gore talk about it as well as plenty of others, but there are still so many people out there who are just not sure what global warming is all about. People are not sure what all the fuss is about. It is important to be aware of environmental issues in the world today.

There are actually several known causes of global warming and only by acknowledging the causes can anything positive actually get done about it.

Causes

Although there are different causes that are contributing to global warming, more than anything it has to do with humans and what we as a nation are doing to the earth and what sort of an effect it is having. Greenhouse gases are thought to be the number one cause. These can occur naturally but they are also the result of many human processes including fuel consumption.

By driving cars for instance, greenhouse gases are emitted and when you stop to consider how many millions of people are driving around each day, it is easy to see why this would be such a problem. This is certainly one of the most major causes and one that is therefore crucial to pay attention to.

Aviation is considered as being another of the main causes of global warming. People are constantly traveling around the world for personal and professional reasons and it is costing us because it is having a negative effect on the world that we live in.

People really need to start paying more attention to what they are doing and realize that there are very simple steps that can be taken in order to have a more positive impact on the earth and take care of it. Global warming is just one of many environmental issues that we are dealing with right now but there are many others as well. At least by being aware of this causes, we are able to move forward and do what we can in order to protect the environment.

Causes of Global Warming

In present times, the green house gases like methane, carbon dioxide, and nitrous oxide are playing havoc on our environment. These green house gases trap the heat of sun into earth’s atmosphere causing increase in the temperature. Power plants are the major sources of carbon dioxide. These power plants emit huge quantities of carbon dioxide, which is produced when fossil fuel is burnt for generation of electricity. Burning of gasoline in vehicles contributes to more than 20% of carbon dioxide emission in the atmosphere.

Major Contributors of Global Warming

Commercial and residential buildings need a lot of fuel to be burnt, emitting huge amounts of carbon dioxide in the atmosphere. As compared to carbon dioxide, methane is twenty times more effectual at entrapping the heat in the atmosphere. Methane is obtained from several resources such as bovine flatulence, paddles, fossil fuel manufacture and bacteria in bogs. Flood in the fields decays the organic matter, and releases methane in the atmosphere. Nylon and nitric acid production, use of fertilizers in the agriculture, cars with catalytic converters and burning of organic matter are main sources of nitrous oxide. More than 33% of carbon dioxide emission comes from engines of light trucks and cars. Vehicles that have poor mileage contribute maximum to the global warming.

The way we use our land is one of the major cause of global warming. Modern agriculture practices that are used to grow cereals, breed animals, grow vegetables and fruits and other foods for human consumption, and all these agricultural practices lead to emission of greenhouse gases including nitrous oxide and methane.

There is no doubt that in last few decades, deforestation has become one of the biggest sources of greenhouse gas emissions. Carbon dioxide is the main gas emitted, in addition to small amounts of nitrous oxide and methane. Tropical rainforests are very crucial for regulating the regional and global climate patterns. The environment can get tremendously affected if these forests are destroyed. Rainforests remove the carbon dioxide from the atmosphere by the process of photosynthesis.

Another reason and cause of global warming is the fact that human population is growing, and in addition to increase in the fuel usage for transportation, energy and power, people need to be fed, which leads to increased deforestation for the purpose of agriculture.

There are some natural causes of global warming as well. Temperature of the planet is affected by changes in the shape of orbit of Earth around the Sun, and also by the tilt of its axis because both these factors affect the amount of solar energy received by the planet. As Sun is the only source of energy responsible for functioning of Earth’s climate system, change in output of solar energy can lead to change in the climate, especially, global warming.

One more natural cause of global warming is the aerosol emission of volcanic eruptions that blocks the sunlight, and causes short-term cooling on affected parts of the earth. The volcanic eruptions emit carbon dioxide and carbon monoxide, however, most scientists believe that humans are far more responsible for the damage as compared to volcanic eruptions.

Change in ocean current is also a natural cause of global warming because rise and fall of current creates global change. Oceanic currents have considerable effect on the changes of heat pattern around the earth. This effect varies from region to region, and may also be related to rotation of sun.
