Facts About Global Warming you Should Know

Global warming is not a phenomenon of the 20th century. This in fact happened in the past more than once, along with extreme cold period known as the Ice Age. With so much written and reported about global warming, it is sometimes difficult to detect that fact and that only a part of scientific scare. Here are some facts about global warming that might help:

What exactly is global warming?
Global warming is in fact the increase in temperature of the earth's atmosphere, land and sea. Earth surface temperature is 59F and the average over the past one hundred years, this number had risen to about 1F. In 2100, the average global temperature changes range from 2.5f to about 10F, enough to melt glaciers and polar ice.

Causes of global warming
Global warming is and will always naturally. Why would you like to draw in our lives is caused by the fact that human activities and practices have contributed substantially to the incidence and severity. With the advent of industrialization and careless environmental practices, we global temperatures rose an average negative contribution due to the greenhouse effect.

It started about 240 years ago, when the industrial revolution was born. As more and more fossil fuels in the form of oil extracted and burned, gases as a byproduct of the process that began to be released into the atmosphere. Currently it is estimated that 75% of elevated carbon dioxide levels in Earth's atmosphere caused by burning fossil fuels.

Global warming and the greenhouse effect
Global warming is associated with changes in the emission of the Earth effect. Gases occur naturally in the atmosphere of the earth and act both for protection and heat retention. These gases are carbon dioxide, methane, nitrous oxide and water vapor. Of these, water vapor is a greenhouse gas most dominant and abundant.

Global warming and the greenhouse effect is not the same. The greenhouse effect refers to the natural processes occurring in the atmosphere of the earth. If this process is interrupted, it can contribute to global warming.

When the sunlight hit the earth, the heat bounces back into the atmosphere where these gases contain the heat and stay in the existence of the planet warm. This is an important natural process and allows life forms to survive and thrive. The problem only occurs when these gases multiply and build, with heat efficiently and thus global warming atmosphere.

If an increase in average temperature of the earth, the impacts on land and sea surface is clear. polar ice caps melt along with glaciers, contributing to a higher level and warmer ocean. At the end of this century, it is estimated that sea levels could increase from 4 cm to a high of around 40 inches if global warming continues.

Global warming may also affect the behavior of the wind and can also contribute to a harsh and dry climate, with frequent storms Visits strong. Water from heavier rainfall will not take long to irrigate the land, but because of the warm climate, the water in the surface of the earth quickly evaporate. This has a significant impact on agricultural practices not only in America but also worldwide.

Another phenomenon that is equated with global warming, El Nino. El Nino took place, with possibly thousands of years and not directly caused by global warming. However, changes in the average temperature of the planet to contribute to the severity and frequency.

Other human practices that contribute to global warming
Agricultural revolution also contributed to global warming. As the community becomes more and requires land from the forest into residential areas and commercial biomass is reduced, contributing to the increase in carbon dioxide presence in the area. Because carbon dioxide is processed by plants and trees, their absence contributes to the improvement of the company.

It is estimated that approximately 25% of the annual increase in carbon dioxide in the atmosphere of the earth is caused by extreme changes and the use of natural resources of the earth. Other practices including deforestation, salinization, desertification and overgrazing also contribute to global warming. But many scientists believe and agree that this contribution is small and indirect.

Facing the facts of global warming
Countries around the world has only begun to address the adverse effects of global warming is not only recognizable in the world of politics and economics, but also for humanity in general. Many of the governments of the world have encouraged implementation of measures to try the problem of global warming to overcome through the steps carefully and practices to protect and respect the environment.
