Earth does not belong to just particular individual. It has been present since millions and billions of years and has undergone radical changes. These changes have occurred in terms of climate and evolution of species over a lot of time. Global Warming is one aspect of how nature and climate has changed over time.

Desperate Times – Desperate Measures

Desperate Times – Desperate Measures

Evolution of mankind is a natural process. The catalyst in this process is the constantly changing climate. Due to climate change a lot things have simple reshaped and reconstructed themselves. However, a very major and serious threat waits. Global Warming is an issue that must be addressed promptly and contributions must be made to save the planet. Global Warming must be fought back to survive.

Responsibility Of Mankind – Global Warming

As the prime and most intelligent specie on the planet, it is the responsibility of mankind to prevent Global Warming. The Global Warming is an issue of intense debate and a lot of controversy. Clear signs of the Global Warming appeared back in 20th century after mass industrial revolution worldwide and weather changes.

Effects Of Global Warming On People

Many individuals have personally witnessed the Global Warming changes. Global Warming is primarily the increase in temperature. The temperature increase is quite drastic and bizarre. Global Warming is said to have increased the Earth’s temperature which may have several negative effects on the environment.

Famous Events – Global Warming Is The Cause

Some of the most renowned events occurred due to Global Warming is the breaking of ice glaciers. Ice glaciers are large masses of ice and snow accumulated together. In 2005, experts noticed the Ayles Ice Shelf breakup. This breaking was visible through satellite images. The glacier was as long as 41 miles and one of the largest.

Breaking Of Ice Shelf’s

Similarly, other Ice Shelf’s have completely broken down. Much more has occurred on the North Pole where snow caps are constantly melting. The melting of snow causes a very negative impact on the natural environment. Water level in the sea rises dramatically. It causes flooding in the low lying areas.

The Effects Of Global Warming

The melting of ice and Global Warming also triggers certain reactions. The depletion of Ozone Layer is one of those processes. Ultra Violet Rays penetrate the Earth’s environment and cause diseases like Leukemia and Skin Cancer. Eye cataracts are also caused by such rays and certain complications in pregnancy also arise.

Awareness Campaigns – Time To Wake Up

Awareness Campaigns Time To Wake Up

Even after a lot of awareness campaigns many individuals are not aware of Global Warming. It is one threat that must be faced together as a collective community. People many a times do not consider it their duty to contribute. It must be kept in mind that efforts must be made collectively to ensure the survival of our species.

Life Is Linked – How Global Warming Works

Everything on Earth is interconnected. One process affects the other and a series of chain reactions may cause invertible disasters. The rising of oceans and seas will cause low lying areas to permanently drown. Rain Forest and other natural biomes will completely wipe out and marine life will slowly extinct.

Conserve The Environment – Save The Earth

Global Warming must be dealt with immediately. Conservation of environment must be kept it mind. Many individuals consider Global Warming as a myth. However it is not a myth. Global Warming is very real and already infiltrated the lives of millions of individuals directly or indirectly.

Global Warming and Its Causes http://www.solarpowerwindenergy.org/global-warming-and-its-causes/ http://www.solarpowerwindenergy.org/global-warming-and-its-causes/#comments Sat, 30 Oct 2010 13:00:03 +0000 R. MAK. http://www.solarpowerwindenergy.org/?p=4533 Global warming is the most pricking question in this age. But still a great number of people are unaware of what global warming is and what its causes are. Let’s have a look on the causes of global warming. To do so, first we should know that global warming is an overall state of existence that has evolved from a number of environmental factors. All these factors merged together and gave birth to a big problem in the form of series of events that is collectively called as the global warming.

Depletion of Ozone

The global warming gained the attention of people after the depletion of Ozone layer. A molecular form of oxygen is called Ozone. The ozone layer is set in the lower part of the stratosphere of the Earth in the form of the thin strata forming a layer.

Due to the depletion of ozone layer, ultraviolet rays reach the surface of the earth directly and cause certain types of skin and other problems. Is it right that rise in UV radiations equate to global warming? The answer is not really. In reality, in the opinion of several scientists, depletion of the Ozone layer ending in cooling of both the troposphere and stratosphere. The main reason to co-relate depletion of Ozone layer to the global warming is to represent the need to maintain a balance between harmful radiation to reach the surface of the earth and human life to stop the increase the water and air temperature.

Most Remarkable Cause of Global Warming

Carbon dioxide emission is the principle cause of global warming. Currently carbon dioxide is being released into atmosphere at a crazy rate and that rate is increasing with the passage of time such as, 8 billions of carbon dioxide entered in atmosphere just in past year. Some of this occurs due to certain natural activity like volcanic eruptions, breathing of human being etc. Earth is naturally programmed to absorb those emissions into regenerative process. The problem of global warming rose from the burning of fossil fuel that emits great quantity of carbon dioxide in atmosphere.

According to careful estimations, currently 40% of all carbon dioxide emissions that occur in the whole world are caused by power plants. These power plants use burning coals, natural gas, and diesel fuel. Some power plants also burn garbage, some burns methane that is produced from garbage. 33% of all the carbon dioxide that is emitted into atmosphere comes from the products of trucks and cars. 3.5% of carbon dioxide comes from the aircraft traveling and the sad news is that air crafts and jets directly emit the pollutants into the troposphere.

Carbon Dioxide percentage in atmosphere

It is estimated that 12% of carbon dioxide is released in atmosphere but this figure varies from source to source. In certain places the emissions from buildings are as higher as 33%. The new constructions of buildings emit more carbon dioxide in atmosphere. That’s due to the material used in their production and energy used during their construction. According to the general consumption, the building consumes energy in the way in which a car burns the fuel. It is to remember that 98% of all the carbon dioxide emissions are associated with the energy production. 80% emissions of that emission convert into greenhouse gases.

Another contributor to Global warming

The next most significant cause of global warming is methane gas. Methane is emitted into atmosphere from a number of sources. These sources are natural and mane mad emissions. The natural emissions include wetlands, termites, the ocean and hydrates. Where as inorganic sources include livestock, landfills, waste treatment and biomass burning. Methane is twenty times stronger than greenhouse gases. This feature makes methane more powerful than carbon dioxide.

Other greenhouse gases

We should not forget that not all greenhouse gases are dangerous as methane. Another danger to our earth is simple water. That’s because atmosphere is set to have a set content of water as vapor. These vapors absorb the heat and radiate it like every molecule does in the air. But if the lower troposphere has entered water vapor that gaseous water is a stronger greenhouse gas.

Nitrous oxide is another harmful greenhouse gas. The sources of nitric oxide are cars using catalytic converters, fertilizer plants, nylon manufacturing, natural sources such as, oceans and rain forests.

All above mentioned greenhouse gases and some other make the foundation of the global warming. Global warming is not a single event or activity, it is based on a chain of reactions that are caused by various purposes and cause harm to our earth.

Green Buildings- A Solution To Global Warming http://www.solarpowerwindenergy.org/green-buildings-a-solution-to-global-warming/ http://www.solarpowerwindenergy.org/green-buildings-a-solution-to-global-warming/#comments Fri, 29 Oct 2010 13:00:26 +0000 R. MAK. http://www.solarpowerwindenergy.org/?p=4515 A “Green Building” is an environmentally friendly building. Confused? In a green building, the effects of materials on the environment are considered. It consists of processes that do not harm the nature.

Purpose of Green Building:

There are 4 main purposes of green building: siting and design efficiency, energy efficiency, water efficiency and material efficiency.

1) Siting And Design Efficiency:

  • Siting and Design goes hand in hand.
  • Siting involves the factors such as exposure to sun and wind.
  • One of the best way of conserving energy is to place a home facing the west side.
  • In the design part, you have to select the type of windows to be placed for efficiency.
  • In northern climate, you can use large double paned windows. This is allows greenhouse warming effect in one location.
  • You can even use small tinted glass.
  • In short, selecting a suitable area and then designing it with ways to save energy is done in siting and design efficiency.

2) Energy Efficiency:

  • Green buildings include ways to minimize energy.
  • Your electricity bill increases with the use of heaters, airconditioners, washing machines and dishwashers.
  • You can include pipe ventilation, rooftop solar panels and geothermal heat exchangers.
  • These things can make your home cool, give you hot water and power lights.
  • Thus you are able to save energy and money.

3) Water Efficiency:

  • By reducing water efficiency, you improve the quality of water.
  • You achieve two goals by diverting the gray water to the lawn.
  • You protect the diminishment of water supplies.
  • When you include the water treatment in construction, you are able to save money.

4) Materials Efficiency:

  • You can use naturally made materials in a green building.
  • You can use recycled materials since they reduce the cost of home.
  • Skylights and air pipe ventilation can improve the quality of life.
  • Use of natural building materials reduces the entry of volatile particles. The air remains fresh.
  • Man-made materials diffuse harmful gases in the atmosphere.

Cost of Building a “Green Building”:

The average cost of building a green building is 5% more than the normal construction. But then just imagine how much you will save in future. The green buildings can give you a saving return of about 50-70%. The use of solar panels and pipe ventilation reduces your electricity bill for sure.

Lastly, the green building has no harmful effect on the environment. It is known to improve the quality of your life and brighten our planet Earth.

Global Warming’s Global Effects http://www.solarpowerwindenergy.org/global-warmings-global-effects/ http://www.solarpowerwindenergy.org/global-warmings-global-effects/#comments Thu, 23 Sep 2010 17:05:00 +0000 R. MAK. http://www.solarpowerwindenergy.org/?p=4140 Global warming needs no introduction in today’s world. Therefore avoiding the intricacies of global warming I would like to write this article in the hope of sharing some insight into what could actually happen or what is exactly happening to our planet Earth because of global warming. This term has caused global affects on agriculture, weather, which has further caused a tremendous shift in the economy of countries. Let me explain in a brief manner global warming’s global effects.

Rising Sea Levels

Regarding sea level rising, there is a misconception that I need to clarify. It is not because of the melting of the Polar zone that causes rising sea levels, it is the thermal expansion that causes the sea to have a rising level. The meltdown at the Polar zones join the oceans, but they hardly make up for rising levels.

sea_level_rising

Currently though, it is predicted that within the next 100 years, if the same amount of global warming occurs, it is probable that islands may be eliminated completely. Not only that but areas near the sea may loose million of acres of land. It is surely a problem to be worried about, as already recently an island in Maldives has been eaten up by the rising sea level.

Diminishing Sweet Water

One major problem to consider is that of salt water mixture with sweet water. You must be thinking how this is possible?

Well, you see, rising sea levels could destroy the sweet water of rivers and this could lead to agricultural short fall in low lying areas around the world.

diminishing sea water

According to statistics the Indian River in America would cease to exist if rising sea levels occur and this would be a problem as the agricultural production is largely dependent on that river.

Extreme Weather

I don’t think there is a need to stress about this situation as we all have recently witnessed the extreme climate and weather change in different parts of the world. Russia facing severe heat wave, while Pakistan suffered from severe flooding. This is one effect of global warming.

badweather

Hurricanes, tornadoes, cyclones are becoming a norm for costal areas. There is an alarming rate of hurricane frequency which has amounted to 35% over the last 30 years. With the planetary conditions that we face now, it is feared to go much above that estimate.

Extreme Climate

People often mix up climate with weather and there is a confusion about the two. Climate is actually a weather pattern, not the weather itself and climate change is global. With the global warming on the rise, there is extreme hot seasons in one part of the world, while extreme cold in the other part.

extreme_climate

This is the reason why glaciers in the northern hemispheres are melting and there is a 50% decrease in their size. This is the one sole reason why there is a constant influx of landslides, floods and lake overflows in different parts of the world. If the sweet water preserves melts too quickly and joins with the ocean water, we could all die out of THIRST.

These are just some of the brief highlights of global warming’s global effects. We should not forget droughts, forest fires, heat waves, extreme cold, and many other problems that is harming our planet Earth. People have still not realized the implications of global warming and are continuing to live a life of ignorance. SAD!

The Green House Effect http://www.solarpowerwindenergy.org/the-green-house-effect/ http://www.solarpowerwindenergy.org/the-green-house-effect/#comments Thu, 09 Sep 2010 09:17:34 +0000 R. MAK. http://www.solarpowerwindenergy.org/?p=4025 The most prevailing concept about Green House Effect is its indication as a Global Warning, but the truth is, without Green House Effect life would not have been possible on earth surface.

Green house effect

Before we talk about its being a Global Warning, let us see what good The Green House Effect does for us.

The sunlight reaches the earth in the form of short wavelengths which are easily absorbed through the transparent medium. As a result the heated objects on earth surface emit energy in the form of high wavelengths, called Infrared Radiation.These high energy wavelengths do not  go back to the space, instead mostly are reflected back to the surface.

What Green House does is, it absorbs the energy into it, ultimately making it possible for the surface to maintain a temperature which is suitable for life. Green  House Effect is caused by the some gases, called Green House Gases in the air mainly Carbon dioxide, Nitrous oxide,  Ozone. Methane etc.  These gases absorb the energy  enough to regulate the climate and maintain life on earth. Green Houses  Gases constitute only 1% of air make up.

Had there been no Green House Effect, it would not have been possible for surface to radiates moderate amount of energy, as a result the temperature of earth would have been much colder than what it is now. The energy which is trapped by Green House Effect is regulated by atmosphere. Thus, the atmosphere plays very important role in causing it.

The energy is regualated in such a way that niether it gives us sunburn nor it lowers down to a degree that we find it difficult to live the life. According to the estimation by scientists, without the Green House Effect, earth would have been colder by 45 degrees Farenheight.

Global Warning:

How do we human being contribute to upset the Green House Effect?

We add to the Green House Gases by contributing to the incresed level of Metahne, Nitrous oxide, and Cardbon dioxide; Use of Automobiles cuses it.  Factoy wsates also have gases which do not occur naturally. By doing all this, we basically disturb the natural process of the green house effect.

MAK. http://www.solarpowerwindenergy.org/?p=4018 All the natural destruction on the earth are caused by global warming. The cutting down of the trees and destruction of the natural resources causes all the global warming. Global warming is going on affecting the earth. Floods, tsunami, earthquakes all cause because the global warming causes the movement of the earth which results in destruction. The wrong use of the natural resources is one big mistake we do which will cause destruction on this earth one day. It is important for everyone living on this earth to take care of it and try to save Mother Nature. Of course we can not within seconds or minutes.

causes of global warming

We all need to do proper planning and think of various solutions which will help us in saving our mother earth and stopping it from global warming.

There are many solutions we can take in order to protect our mother earth and to protect it from the global warming and any damage. For this purpose we should make use of things which are produced natural and it is good to make use of natural resources in good way. As the years are passing many methods are being introduced to prevent the global warming and to provide everyone with such things which have more use of natural resources and which do not create destructiveness on the earth. As it is everyone’s goal to provide things only to improve the earth.

Solar and wind power energies play an important role in stopping the global warming as they make use of the natural light and the wind in a proper manner. All these things which are used naturally and require solar lights are good to be used by everyone as they do not in any way aim to destruct the earth and prevent global warming.

Moreover, we can put a stop to global warming by changing few habits and making use of natural things in such a way that they help us in every possible way.

Global Warming – As An Opinion http://www.solarpowerwindenergy.org/global-warming-as-an-opinion/ http://www.solarpowerwindenergy.org/global-warming-as-an-opinion/#comments Tue, 31 Aug 2010 18:41:00 +0000 R. MAK. http://www.solarpowerwindenergy.org/?p=3954 Global warming is a hot, controversial topic, that seems to be eating away at every citizen, every leadership and every country, but the sad fact; people don’t care less. So what exactly is this thing called, “Global Warming”? Let’s have a closer look.

As Public Opinion

As an opinion global warming means, the end of the world. Ask any common citizen or even a kid as to what they think is global warming, you’ll get a straight answer, “the Earth dying.” No scientific claims, no political answers. And this public opinion is in a way true. With the constant pollution and emission of dangerous gases, our planet Earth is slowly, gradually suffocating and dying, and if this is the pattern that we continue to live in, Mother Nature might as well bid us farewell. Still people will continue to use a car for a five minutes walk, continue to burn stuff, continue to live life like as if nothing affects them.

global warming

As a Political Opinion

Politicians in collaboration with multinational leaders may state global warming as a “social and financial concern”. Social as it would require  massive setups to control it and financial as most politicians and corporates don’t really want to waste their invested money in carbon fuels and oil.

They don’t really care if the world gets to an end, as all they care is their large banks and investments. Politicians use global warming as a premise for their election campaigns, claiming great legal rights, but doing nothing in actual. Sad but true.

As a Scientific Opinion

Ok! atleast science and scientists are concerned with the world. According to science, what is global warming? “The Earth growing hotter each day, due to the massive amount of pollution, carbon dioxide and other green house gases that is emitted into the air.” This makes the planet hotter, creating a major global shift in weather and climate patterns. More rainfalls, more floods, more heat, more temperatures.

Scientists need to make new devices, bring up new inventions to curb global warming. If it wasn’t for these guys, we wouldn’t be having solar power, green electricity or any of that other popular renewable energy that we have been reading about. The problem is the time duration. It takes very long to test, approve and make a product available for commercial use.

Conclusion

Global warming is a hugely debated topic, which unfortunately has remained a debated topic, even though we are facing glaring facts of its impact on us. As common public the least we can do is try to individually help in the healing process. Don’t use fossil fuels too much, save electricity, save water, and the other basic precautions.

There is nothing that we can expect from our leaders and politicians, as whatever has to be done has to start from the people. We  have created a vicious cycle of consumerism, which is now gradually affecting the very core of our planet and needless to say 50 years from now, we will be facing severe weather conditions. Let’s not keep global warming as an opinion anymore, but rather as a problem that needs action right away.

Natural Energy Sources http://www.solarpowerwindenergy.org/natural-energy-sources/ http://www.solarpowerwindenergy.org/natural-energy-sources/#comments Tue, 17 Aug 2010 05:39:05 +0000 R. MAK. http://www.solarpowerwindenergy.org/?p=3802 Most countries of the world are trying to lessen or completely end their dependency on fossil fuel; this is because of the rising prices of fossil fuel and its pollution effects on our environment and our health, which is also contributing a great deal in the climate change and global warming. The use of natural energy for heating, electricity production and fueling purposes is gaining in popularity day by day. By investing in natural and alternative sources of energy can help reduce the burden of fossil fuel on our country’s economy. Anyone can contribute to improve the current condition of our environment by switching to an alternative or natural energy sources. Some natural energy sources are wind energy, solar energy, tidal energy. There are other renewable energy like hydrogen fuel and biomass also.

Solar energy:

Solar energy is the energy which the sun produces in the form of solar radiation. Through the use of solar panels or solar cells, the photons in the solar radiation are converted into electricity. However one disadvantage going with this form of energy is the high prices of solar panels. Large numbers of solar panels are necessary to produce a substantial amount of electricity.

Wind Energy:

Another form of natural energy is wind energy. This form of natural energy source uses a wind turbine which harnesses the power of the wind to produce electricity. In order to produce decent amount of electricity, a large wind turbine is required. These turbines are usually made from minerals obtained in an impure way but after the turbines are built, it requires no fossil fuel or minerals to run it, but may require it for its maintenance.

Wave energy:

Wave energy or tidal energy harnesses the power of the waves to run water turbines to produce electricity. This is a renewable energy source as tides go in and out the turbines.

By doing our part by switching to a natural energy source we will be taking a large step forward in the fight for a better, cleaner and safer environment for us and for our future generation.

Severe Effects Of Global Warming To Come http://www.solarpowerwindenergy.org/severe-effects-of-global-warming-to-come/ http://www.solarpowerwindenergy.org/severe-effects-of-global-warming-to-come/#comments Fri, 07 May 2010 17:44:00 +0000 R. MAK. http://www.solarpowerwindenergy.org/?p=3119 According to the researchers of Purdue University and the University of New South Wales, Australia, we could face some severe effects of global warming quite soon. Although we have already seen a wide range of different natural disasters that all link back to the changing climatic condition, the researchers claim that if the green house emissions continue at the same rate, planet Earth would soon be inhabitable by humans and mammals.

global warming

Keeping in view the fact that if the temperature of the earth keeps rising considerably due to global warming, it will have extremely harmful consequences for living beings. The present pace of global warming is considered to be the maximum tolerable temperature for the survival of living beings that can be surpassed.

The researchers have calculated the ‘wet bulb ‘temperature. According to them, the wet bulb temperature is the maximum tolerable temperature in which the living organisms can survive.

Concerns are that if the corrective measures are not taken in time to control the global warming, the temperatures could go beyond the wet bulb limit in the future. The wet bulb temperature is found out by taking into consideration the temperature and atmospheric humidity. The name has been derived from the way it is measured. This temperature is measured by covering a standard thermometer bulb with a wet cloth and ventilating it fully.

The lead author of the paper, Steven Sherwood explained that prolonged wet-bulb temperatures above 95 degrees would prove to be intolerable after some hours. Moreover, if the wet bulb temperatures are reached, humans would overheat even if they stand naked in the shade or stand in front of a fan. They would not be able to bear the high temperature. This is due to the fact that beyond a certain temperature, human bodies can not get rid of the heat through sweating and other biological mechanisms, which increases their core body temperatures.

The study does not give a definite time for this ultimate climate situation, but warns of the severity of the situation.

How Is Global Warming Produced? http://www.solarpowerwindenergy.org/how-is-global-warming-produced/ http://www.solarpowerwindenergy.org/how-is-global-warming-produced/#comments Fri, 30 Apr 2010 15:00:00 +0000 R. MAK. http://www.solarpowerwindenergy.org/?p=2976 The overall global climate change has finally convinced everyone that climate change is for real, has begun, and is mostly due to human activities.

According to experts, the effects of global warming are extremely hazardous and extensive. Most of the times, these consequences are only thought of as threats to polar bears, exotic wildlife, and beautiful glaciers. But it is important to understand that climate change threatens more than just the animals and natural landscapes. It can also cause harm to human health and pose serious problems.

In order to understand the effects of global warming, we must first understand how global warming works. We all know that sunshine warms the earth. But when the sun’s radiations enter the atmosphere, a part of the radiations are bounced back into space, and another portion is absorbed by clouds and water vapors, but the majority strikes the planet’s surface.

This solar energy keeps the earth warm, but it’s also reflected back into the atmosphere in the form of infrared radiation. While some of the infrared goes through the atmosphere into space, some of it bounces off the atmospheric gases and comes back to earth, where it adds more warmth, becoming trapped in between the earth and the atmosphere.

The atmospheric gases that reflect back the infrared radiations to earth are known as greenhouse gases. Greenhouse effect is essential for the survival of living beings on Earth as without this, too much solar energy would be lost, and the earth would be too cold for any living organism to survive.

But due to the industrial revolution, the level of atmospheric greenhouse gases has increased greatly, and the increase has risen over the past 50 years. This means that far more infrared radiations are reflected back to earth, where they produce global warming. According to scientists, the earth’s temperature has increased by 0.6°C during the 20th century, which can possible rise by as much as 4.4°C during this century.
