The Effect of Global Warming on Hurricanes

Reputation Professor Complaints Effect By: Rich Johnson

Global Warming is a term denoting a gradual warming of the Earths average temperature. The term has become synonymous to the Earths warming exclusively due to man-made effects, especially carbon dioxide. Carbon dioxide concentrations have increased from 300 parts per million to 384 parts per million since 1900, with the most accelerated increase during the past 40 years. Some scientists have drawn the conclusion that the increase in the Earths average temperature (about 1°F since 1975) is essentially solely based on man-made activities such as the burning of fossil fuels, biomass burning, and deforestation

Causes of Global Warming

The Earths atmosphere is made up of different gases. Nitrogen makes up 78% of the total composition, Oxygen 21%, Argon 1% and traces gases .1%. Carbon dioxide makes up most of the volume of the rare gases. Water vapor varies from almost 0% over the deserts to 4% over the oceans. Water vapor, carbon dioxide, methane, ozone, and nitrous oxide are the gases of interest since these are the greenhouse gases. Greenhouse gases can reradiate heat or trap heat absorbed by the Earth from the sun. Water vapor is by far the largest mechanism for heat retention out of the greenhouse gases.

In the past, the Earths orbital eccentricity, variance of the tilt and wobble have led to periods of warmer weather. Even though the solar energy from the sun is considered a constant, a slight change could cause temperature fluctuations. Recently, Mars has also shown a decrease in ice coverage without greenhouse gas changes. The cause for the reduction in aerial coverage is unknown.

In summary, there are three mechanisms which would cause global warming, or in other words allow for a warming of the Earths average temperature. These are: (1) solar energy variance, (2) gradual changes in the Earths orbit, tilt, and wobble, and (3) greenhouse gas changes. It is difficult to calculate what percentage of the recent warming could be attributed to human activities. We can eliminate changes in the Earths orbit, tilt, and wobble causing a temperature increase since these are long term effects.

What are the Effects of Global Warming on Hurricanes?

There is a common misconception that since the global temperature has increased, hurricanes also must increase in number and intensity. The primary factor in the ability of a hurricane to strengthen or weaken is the wind shear profile of the atmosphere - not water temperature. It always has been warm enough in the tropics to produce hurricanes. This temperature equates to a sea surface temperature of about 80°F. If you study the behavior of hurricanes you can find cases where hurricanes have strengthened over cooler water and have weakened over warmer water. There may be a small “boost” to a hurricanes strength as it moves over the Gulf Stream, if upper air wind profiles do not change much. Some of the computer generated hurricane models have this bias built in and will rapidly strengthen a tropical cyclone if predicted to go over a warm pool of water.

The recent upturn in tropical cyclone activity was predicted long before Global Warming became a household name. The tropical Atlantic has been known to vary in cycles, and this recent upturn was expected. If you were to compare the period from 1900 to about 1950, with the 1950s until now, you would find an actual decrease in the average number of hurricanes and their intensity. It also is noted that the upswing in hurricane numbers over the past ten years or more has been only in the North Atlantic basin. Other hurricane formation regions have not shown this same trend.

The Effects of Global Warming on Hurricanes: Summary

There has been a noted increase in the number of hurricanes in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico since the mid-1990s. The long term average is that ten tropical storms will form per year, of which about six will become hurricanes. Since the mid-1990s the average has been fifteen tropical storms, of which eight have become hurricanes. There has also been an upward trend in the concentration of the greenhouse gas carbon dioxide due to mans activities over the past 100 years. During this time, hurricanes have gone through cycles where they have been more numerous, such as the cycle that we are in now.

Some scientists have drawn a one to one correlation between the Earths temperature increase and the number of hurricanes and their intensity. As we have noted, the number one factor in tropical cyclone intensity is related to the atmospheric wind shear profile. There is even some research that suggests that higher temperatures could actually increase the wind shear profile resulting in a decrease in hurricane activity. The upward cycle in hurricane numbers is expected to continue for several more years. If this trend were to continue for a considerably longer period, only then could one draw a conclusion that warmer temperatures have played some part to cause an increase in tropical cyclone formation.

Fundamental Ways That Could Stop Global Warming

Reputation Professor Fundamental Complaints Author Nathalie Fiset.

What do you think could come in as more important to our basic human needs such as food, shelter, medicine, education or even the need for affection? There could be one issue that would predetermine everything that will transpire on the planet, and that is the planet’s condition. If the world were on the brink of destruction, saving it would be the priority of every single individual. And save it we must. Although the threat is still not at a life and death level, there is an alarming truth that there are several problems that are now bugging the place that we live in. Say hello to global warming. And try to say bye - stop global warming!

Global warming, which is also known as the greenhouse effect, has been here long before you or anybody else out there existed. It’s been here for thousands of years. And through those thousands of years, the earth’s temperature has increased, and so has the effects of global warming. Time magazine has actually coined this problem as a planetary emergency.

There are major solutions that have been done worldwide to cope, alleviate or altogether stop the effects of this major problem. But among these choices, the obvious choice that the human race is supposed to concentrate on is how to stop global warming. Since we have all contributed to the occurrence of global warming (in our own little ways), then we should also join forces in combating this dilemma.

1. Join organizations that promise to educate you about the effects of global warming and what you can do to put a stop to this problem. Be an activist on this matter. After all, everything begins with you.

2. The next step is to conserve energy. And yes, there are so many ways that an individual can save energy. Let’s list some here: car pooling, turning off appliances that are not in use; unplugging any electronic devices that are not in use; buying energy-efficient lamps; keeping the filters of your air-conditioning unit clean; taking a walk (instead of driving); turn off the faucet when enough water has been consumed; do not use appliances or products that release chlorofluorocarbons into the atmosphere (examples are hairsprays and refrigerators that have CFCs); use EEF appliances; start planting trees, etc. These are basic things that we have learned even from grade school and yet, tend to forget the most.

3. If you are a slave of your profession, then, cut on those work hours to help save energy. For every individual that would cut down an hour from his work, there would be millions worth of energy saved. Learn to maximize your time and to properly manage it. I guess you never imagined before that this could also stop global warming, huh?

4. Recycle. Need we elaborate on that?

5. Use environment-friendly fuels and vehicles. They may be a little bit more expensive but they do not contribute to pollution. Honda was the first to come up with a vehicle that is cell-powered, thus, there are no harmful emissions. If you cannot afford cell-powered vehicles just yet, you can opt for those that can run thirty miles in just a gallon of fuel. This way, carbon monoxide is greatly reduced.

6. If you can, harness the power of the sun, wind and water to generate electricity. There are equipments in the market that can be used to harness solar, wind or geothermal energy. These sources of energy are clean and reusable. If, again, you can’t afford to tap on the power of these sources, then, at least, choose an electric provider that does not pollute the environment by the use of fossil fuels.

7. Insulate your home to prevent excessive use of heaters. During summer, dress lightly to minimize the use of air-conditioning units.

Most people would argue that these, altogether, would not stop global warming. Well, maybe for now that is true. But with the collective efforts of each and everyone in the planet, and if everyone would be disciplined enough to care for environmental issues such as this, then even two degrees off the present global temperature would be such a major feat.

The Global Warming Motives

Reputation Professor Complaints Motives Author: AUGUST Leo

At this moment, there are a lot of natural disaster or bad effect of global warming happen in our environment. There are several kinds of regions that have rainy day that much harder than usual. On the other hand, there are several kinds of regions that have sunny day much hotter than usual. More than that, there is also bad impact that caused from those kinds of unusual condition, such as: big flood, land slide in every where, and so on. Actually, you may think how all of those disasters happen in our life. There are several kinds of indicator that can give signal to us about the real threat of global warming.

First indicator of global warming is the melting of ice in the North and South Pole. Currently we can see that there is rapid change of condition in those poles where the ice is melting faster than before. This condition is also threatening the creatures who live at those poles. Second is the increasing of sea surface level. There is an amazing result of research done by environment experts which they said that if all of Greenland were melting down, it can increase the level of sea surface more than 7 meters.

Beside of that, there are also several kinds of motive that caused global warming exist in our life, such as: the extreme change of climate, hot waves that become wilder than before, and the glacier is running out periodically.

We now can see that storm is getting bigger and could trigger a disaster. So what are we waiting for?
