The Environment Pollution

Environment Pollution
By Kh. Atiar Rahman

According to Commoneous, a renowned educationist," What comes from God is true and with the touch of human beings, it becomes untrue". Again, in this context, Keats says," The truth is beauty and beauty is truth ".

Hence all the sources of beauties and the truth are this world. The world we live in is the most attractive place with striking landscapes and features, wild and domesticated animals, and a variety of odoriferous flowers, evergreen trees and the most wonderful creation of the Lord- the human beings.

The world has been created for the human beings so that they would applause the Lord for his power and preserves these natural beauties with undiminished care. But ever since, the world began; man has been doing the opposite thing bit by bit. He has been making progress in science and industry; great deals of landscape and wild life are being abolished day by day.

Over population in small areas has given birth to traffic jam and poverty, which destroys the people. Trees have been cut down to make way for construction of modern buildings. Waste disposal is discarded on land and water, which spread mosquitoes.

Mosquitoes enter the household and sit on food and spray dirt on the food from the waste and many more harmful activities for which man has started to destroy the beauty of the world. In clearing forests to create fields for farming and constructing new houses, man destroys the native animals and takes away their sources of food.

His domestic animals kill them or man haunts them for meat, ivory or furs. Consequentially, the numbers of those haunted animals are minimized and a few numbers of these animals' lives are at stake.

The contaminations are common phenomena through out the world causing a great crisis against our healthy environment in question. Our environment is greatly being polluted every time due to air and water pollution. Air is mainly being polluted from smokes. When the bricks are burnt, unbounded smokes are created. The compositions of such smoke particles are nicotine, thiophin, Furan, phosgene, sulfur dioxide and pyridine.

These particles pollute the air tremendously. The smokes are also created when different vehicles ply over along the streets. For these reasons, all the streets are filled with the smokes that adversely affect the human health conditions. Burning poisonous gases like sulfur dioxide, nitrous oxides, nitric acids and sulfuric acids, again create the smokes. These particles make the air heavy and polluted.

In order to construct buildings, dams and embankments, lots of plants and trees are cut down and subsequently these are burnt for bricks for which air is polluted to a great extent. In the winter-based country, the plants and trees are being planted in the artificial manner by storing sun light under some restricted environment.

The things, which are being done in the green house, are the increasing of carbon dioxide, which affects the environment adversely. We need to ensure the proper use of carbon dioxide by growing the plants and trees adequately without which congenital atmosphere for our survival on earth would not have been possible.

Does Global Warming Affect Hurricanes?

Does Global Warming Affect Hurricanes?
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.

Proof Of Global warming

Proof Of Global Warming

Anyone who believes there has not been proof for global warming has had their heads stuck somewhere recently, and it might not be in the clouds! Don't get me wrong – I'm not one of those starry-eyed liberals.

For a long time, I myself didn't believe the proof of global warming. I had read all of the conservative documents against global warming proof, you see.

There are a wide variety of creative attempts to discredit evidence of global climate change. For example, many people cite studies done more than a decade ago that suggested that we might actually face global cooling as a result of human activities.

If they were wrong then, the skeptics ask, how do we know they're not wrong now?
The answer is simple. Global warming proof is everywhere.

The science has gotten better, and even if there is a small chance that global warming isn't as severe as almost all scientists today agree it is, we can't afford to risk it.

No matter where you live, you have probably noticed the strange weather recently.

In many parts of the world, there have been heat waves, unusual floods or droughts, and even severe storms.

What happened down in New Orleans was only the tip of the iceberg. And speaking of icebergs, had you better get a look at them while you have the chance. they might not be around for that much longer!

The moment I stopped doubting global warming proof was when I returned to our childhood ski resort.

We used to go skiing every winter, and one of the highlights of the trip was a trek up to a magnificent glacier.

Today, barely more than a decade later, that glacier has all but disappeared. The snow that used to stick all winter now only lasts a few weeks at a time, and many of the resorts in the area have closed permanently.

We may not understand all the facts, but something is happening to our environment and it is up to all of us to become involved.

There are many ways to become involved in helping to stop global warming. Writing your congressman is one of the most simple, straightforward, and effective ways.

If you want to go a step further, you can try to write opinion pieces in your local paper, attend protests, and most importantly, curb your consumption.

Use less electricity, plant more trees, and try to use alternative modes of transportation. We have all the global warming proof we need. Now is the time for action!
