There is much controversy regarding this topic. Many claim that global warming is manmade and it is changing the natural climate balance. Others say it is a normal process of nature, which happens every hundred years in the history of the earth.
According with Lariza Montero on her article “Anatomía de los Huracanes”, hurricanes are an enormous storm with extremely strong winds and swirling clouds that spin in spiral form with speeds from 75 to 200 mph. Its diameter is hundreds of kilometers and rotates in counter-clockwise direction around a vortex, or eye. A hurricane typically begins as a thunderstorm or cloud formation called a tropical depression. Most of these depressions die in this form, but some go on to hurricane status. For this to happen, there are three factors involved:
• Low pressure at the surface at low levels of the atmosphere
• Temperature at sea in excess of 27 or 28 degrees Celsius
• High-pressure zone to 10 km of height
When storms become hurricanes, large volumes of warm air start to rise leaving an area of low pressure at the surface. If conditions are right, agitated humid air masses rush to fill that empty space that in minutes, can form an extensive system of winds and clouds. It is a natural process of the planet to move excess heat from the tropics toward colder south and north regions.
Likewise, a hurricane has different categories depending on the intensity of its winds, not by their size “Saffir-Simpson Hurricane Wind Scale”:
Category 1: wind speeds of 74 to 95 mph. Very dangerous winds will produce some damage
Category 2: wind speeds from 96 to 110 mph. extremely dangerous winds will cause extensive damage
Category 3: wind speeds of 111 to 129 mph. Devastating damage...

...generate realistic models of hurricanes, because inside of it has only a few kilometers in diameter, and the spacing between data points in a global climate model is larger than typical global models. That is why scientists are running different techniques to avoid this inconvenience.
As a conclusion, it is possible that many of the data collected from the reported hurricanes are wrong or is not reliable, but the results of studies indicate a significant increase, at least, in the intensity of them.
The debate is still on the table. If global warming is responsible or not for many of the planet 's climate changes has not yet been determined. Moreover, we must change our consumerist lifestyles to help the planet to maintain its sustainability. At the end, the only planet that we have to live is this one, and I think we are destroying it without any kind of compassion.

- The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continue rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World ocean. The average temperature on the Earth was increased by 0.6C. There are various reasons of global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming)....

- One of the most prevalent issues discussed in today’s society is global warming, it has gathered international attention over the past few years due to the increase of temperature throughout the world. Scientists believe that if global warming is not dealt with seriously, within the next few years it may cause excessive glacier melting in which turn would end up flooding cities along coasts, heats and droughts, and crop failure. With these catastrophic consequences it is essential for governments across the world to do their part in ensuring steps are taken to prevent further warming from happening....

- Outline Climate change is caused due to the release of few carbon compounds into the atmosphere, which drastically brought the weather changes all over the world. Climate change is not confined to a single region. It has become an important issue all over the world for the past few years. Reasons of global climatic change Global warming is one of the major reasons in marine pollution. For an instance in the year 2010 there was an oil leakage near Mumbai in the Arabian Sea. Another reason is deforestation.... [tags: Global warming, Climate change, Carbon dioxide]

- The Effects of Global Warming What is global warming, and how is it affecting the Earth and its inhabitants. Global warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earth's surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the coming decades.... [tags: Global Warming Climate Change]

- The Effects of Global Warming On Coral Reefs Graphs Missing Introduction: The effects of global warming touch every human, animal, plant, ocean, landmass, and atmosphere level on this planet. The numerous effects of global warming are mixes of "good" and "bad" results, depending on how your definition of "good" results and "bad" results are. A "good" effect, a person could say, would be for regions with normally cold temperatures to receive warmer temperatures for their normal. Yet, there are more "bad" effects that seem to out weight the "good" effects.... [tags: Environment Global Warming Climate Change]

- ... Lastly, the main green house gas refers to Fluorinated Gases that make up multiple chemical reactions, create holes in the atmosphere, and increase global temperatures. In addition to global warming contributors, the EPA has also identified particulate matter or particle pollution as another source for climate change. Particulate matter ranges in size and texture, which are often found in the air. Particulate matters can be detrimental to the health of humans and the environment. According to the EPA, particulate matter is “emitted directly from a source, such as construction sites, unpaved roads, fields, smokestacks or fires.... [tags: climate, natural causes, environment]

- One of the biggest problem the world is facing nowadays is global warming. Several researchers believe that our making of carbon dioxide and other greenhouse gases is having a warming result on the atmosphere, and this could be very hazardous for human life. Global warming is a massive environmental problem, it has become compulsory to increase awareness about it between the common communities all over the world. Global warming is a major issue right now because of the regular growing temperature of the entire atmosphere.... [tags: Greenhouse gas, Carbon dioxide, Fossil fuel]

- Have you ever wondered about the unusual temperature spikes in the middle of the winter. Why you see all of these polar bears stranded on a small chunk of ice, surrounded by a slush of melting ice. Why are there trends in destructive hurricanes and disasters lately. You’ve heard them before—Hurricane Sandy and Issac, the recent Typhoon Haiyan. People are noticing some changes in the environment, and so are scientists. Is this just the beginning of something horrid or just bad luck. Most people think the answer to these suspicious activities is global warming.... [tags: environmenal issues, climate change]

- For decades societies have been concerned about climate change, and in recent years it has sparked a debate as to whether the earth is warming due to causes by humans or through a natural progression. There are scientists on both sides of the debate, but one thing that they can agree on is that the earth is in fact warming. Studies have indicated a rise in the carbon dioxide levels (CO2) in the earth’s atmosphere that can be attributed to the what is known as the greenhouse affect (Simon, Reece, Dickey, 2007)....

- Global Warming When we think of global warming, we think about Air pollution, rise of temperature, melting glaciers, carbon dioxide emissions and so no. But even though we know that these factors could lead to a global catastrophe, very often we do not realize what king of severe effect the global warming could have on our planet. Imagine that you are placed into the future. It is some where around 2050. You begin to live in this new world, but the planet is not the same any more. You hear about huge storms over much of the North America that cause severe damage and flooding.... [tags: essays research papers]
