The effects of global warming If the greenhouse effect has again been in the news today, it's probably because he is once again being considered as a cause of global warming. Stronger hurricanes, periods of extreme weather, heat waves, the frequency of El Nino, are all attributed to global warming. But how is the greenhouse effect in all these?
What is the greenhouse effect?
The greenhouse effect is the ability of our planet's atmosphere to trap and contain heat. The heat from the sun and is reflected back to the atmosphere. Certain gases are responsible for this provocation, and they include carbon dioxide, nitrous oxide, methane, fluorinated compounds and water vapor. Other synthetic chemicals are also capable of retaining heat in the atmosphere.
In itself, the greenhouse effect is not essentially evil. In fact, this very phenomenon that has produced life on earth as we know it. Think about the greenhouse effect as a natural thermal blanketing for our planet, maintaining a surface temperature that is just right to encourage agencies to develop and survive. Without this blanketing, the earth's climate is too cold - about 59F lower than the average - for our planet to be able to sustain life successfully.
How does the greenhouse effect contribute to global warming?
For more than 4 billion years, the greenhouse effect maintained the temperature of our planet at a favorable level. Gases in the atmosphere act to trap heat and keep our planet insulated, able to maintain. Only problems began to arise when scientists noticed that certain practices and human activities contribute to the modification of this process.
When the industrial revolution began, we have also developed many ways to use fossil fuels for oil, coal and gas. The only way to use these fuels was by burning. As industrialization continued to grow, so does the practice of burning fossil fuels, which releases gases into the atmosphere. The only problem was that these gases have nowhere to go and have continued to accumulate over the years.
The creation, they cause the atmosphere to become more effective in trapping heat, causing climates to turn warmer. This result against nature or man is referred to as global warming.
How global warming affects us
We have experienced the effects of global warming for years and most of these are felt through changes in climate. However, it is important to note that climate change is caused by other factors and not only as an indirect result of the greenhouse effect. Some of these factors include changes in ocean circulation, changes changes in the orbit of our planet and even in the intensity of the sun itself.
Global warming implies increasing the average temperature of the earth's atmosphere near its surface. While global warming is not new to our planet (it took place over long periods in the history of 4.5 billion years the earth alternating with glacial periods), only now when drastic changes to its worldwide has disastrous consequences not only for human nature, but also for the millions of species that depend on the land for their livelihood.
A famous example of the effect of global warming is the increase in sea level caused by melting glaciers. This is a problem not easily seen or felt in countries or regions that are on higher ground, but in many areas, this could mean land (and subsistence opportunities ) lost to the sea An increase of 0.3 meter of sea level for example, can eat up about 15 meters from the beach.
As temperatures rise, countries that have agricultural practices depend strongly on the regularity of the melting glaciers will suffer a lot. For many regions of the world, melting.
