Biofuels
By · CommentsGlobal Warming: Biofuels
We all are aware of bio fuels as products from living things and their metabolic wastes. There are many benefits associated with these useful fuels, the most important being their least contribution towards atmospheric pollution. These fuels offer significant advantage over fossil fuels, as they have nothing surplus to enhance the value of CO2 in air. The fact to support this is that these fuels are obtained from sources like plants, which already utilize significant amount of CO2 to grow and thus, equivalent amount is emitted back while these fuels burn.
Thus, these fuels are carbon-balanced fuels, as these burn with the policy of no gain no loss of CO2. On the other hand, the fossil fuels are known to be highest contributors towards CO2 level enhancement. These fuels, which take millions of years for their production, are burnt instantaneously to dish up human needs and thus, add worth to existing level of CO2. And, the result is increasing rate of greenhouse effect and ultimately, the rise in global warming.
Biofuels In Different Forms
The biofuels are available in the solid form, like wood and cow dung. In the liquid form, these fuels exist as ethanol. These different forms of biofuels are utilized for distinct purposes like producing electricity, fueling vehicles and other useful processes.
Liquid Biofuels Have It All
The liquid biofuels have discovered their wide applications in different fields. Consider the use of ethanol as a replacement for pollution causing fuels like diesel. Also known as biodiesel, due to its background based upon bio-products, this fuel has widely substituted diesel for various types of vehicles. There is no decrease in the efficiency of vehicle, and on top of that, we have in our hand an option for diminishing the pollution causing fuels. Ethanol has become the preferred choice of most of the people in countries like USA.
Assessing The Friendly Nature Of Biofuels
The constant research in the field of biofuels has developed two theories on the environment friendly nature of these fuels. On one hand, these fuels hold significance in maintaining the level of CO2 in air, while there is a pitfall associated with it. The forests are constantly being cleared for obtaining lands to fuel the production of crops. Thus, we are loosing useful resources in the form of forests, which is helpful in absorbing CO2 from atmosphere in large quantities. Moreover, the expenses incurred on crops like corn are becoming unaffordable for various sections. Thus, we really need to evaluate these fuels for possessing environment friendly significance.
Global Warming: Arguments Against
By · CommentsGlobal Warming: Arguments Against
These people are also the part of political set up of United States. However, their existence in the politics has been questioned a number of times. One can remember how Philip Cooney, a high-profile campaigner for oil industry, lost his job for tampering a significant report upon climate change. More recently, the well-known oil companies like Exxon Mobil have spent their money illegally to hire viewpoints against the report issued by reputed body of United Nations, that is the International Panel for Climate Change (IPCC)
Thus, the industrialists, who have something under their belly as contributor to global warming, are in the constant process to invent arguments against global warming. These industry owners have strong associations with people having political base and thus, have powerful support to popularize these beliefs against global warming. The politicians are more than happy in supporting these industry men in return of monetary favors offered by these industrialists. However, the Democrats are opposite sets of people, who are always ready to fight against environmental threats. On the other hand, people sitting in opposite political chamber are leaving no stone unturned in making people believe against global warming. But, the credit goes to eminent personalities like Rush Limbaugh for keeping the battle against global warming alive.
And, there are leading activists like Myron Ebell, who constantly use their public image to generate ideas against global warming. These personalities, known for their outspoken natures, are trump cards for oil companies and other industries to lead the mission of destroying efforts against global warming. They have very right tool to prove global warming as a myth and limit its value as a prank. Do you want to know, what these personalities are served with in return?
Thus, people with intelligent thought processes can predict it easily that arguments against global warming are generated as illegitimate children of some interest groups. If science is to be believed, then you must prepare yourself for facing the evil forces of global warming ruling the world. And this is going to happen due to lack of efforts made by people, who are constantly deviated from their paths by these baseless arguments.
Global Warming: Hoax?
The supporters of global warming as a hoax take advantage of scientific researches in saying that there is no concrete proof available to accomplish the fact that humans are producers of global warming. According to them, this process existed many decades ago, when there was not a single trace of industrial setup.
As far as the issue of ice melting at alarming rate is concerned, this group of people contradicts by saying that an equivalent amount of ice is thickening simultaneously. For the reasons behind heating and cooling of atmosphere, they consider the role of natural processes like volcano eruptions. Thus, these people are popularizing the belief that atmosphere around our planet is filled with greenhouse gases by emission of these gases from volcanoes.
The people treating global warming as a hoax wants to disclose the real motive behind efforts of environmentalists against global warming, however these real intentions are still under dark secrets. These people speak further about oceans, trees and vegetation decay as other contributors towards global warming. If these people are to be believed, all the above-mentioned entities are responsible for adding methane as a harmful gas to atmosphere. These people consider human activities as contributors to global warming, only up to the level of 1 percent. Thus, by putting a hold on sources like SUVs is going to bring down global warming by a negligible value.
Thus, these believers of global warming as a prank are not ready to blame human activities for global warming. These people trace the history and cite the instances, where natural processes are depicted as major contributors to global warming. However, these people lack scientific foundations to prove their beliefs. On the other hand, the people considering global warming as a threat are owners of scientific facts to blame human activities for global warming. The issue requires another level of research to prove one of these groups baseless and act according to the beliefs of other.
Global Warming: Polar Bears
By · CommentsGlobal Warming: Polar Bears
The mother teaches expert hunting techniques to the surviving cubs. The process is continued for as many as two seasons, spending almost eight months at this place. This is the time period during which a considerable amount of weight is gained by these mammals. These animals require this weight for surviving in summer season. Thus, male bears are expected to gain 1,000 ponds, whereas their female counterparts achieve 600 pounds in this period of time.
Having said all, it is time to introduce the reasons, which have proved to be the potential enemies of this specie. Firstly, these animals are hunted for meat as well as fur. Secondly, human activities have threatened their living by poisoning their world with global warming. It is because of this warming that ice melts before expected in Hudson bay.
This premature melting of ice has restricted the time period for polar bears to attain desired amount of weight on their body. The reason behind this is that due to melting of ice, seals, the only food of these bears disappears from the scene. As the female polar bears require considerable mass for giving birth and feeding their young ones, this scarcity of food adds to their woes. These females are prohibited to regain their weights lost by them during reproduction.
This has led to less amount of fat on adult male bears. Moreover, the mother bears are not able to reproduce healthy cubs and in most cases, the cubs die to lack of feed from thin mothers. Thus, the population of cubs is dropping with every passing year. The increasing mercury in the region also exploits the habitat of these polar bears, which reside in snow dens. This exploitation is not limited to polar bears, as ringed seals are also included in this objectionable issue. Thus, human activities are trying to break the existing food chains in nature.
Global Warming: Clean Sources of Energy
By · CommentsGlobal Warming: Clean Sources of Energy
When it comes to renewable energy, wind energy is a useful option. Electrify produced by the spinning wheels is versatile and can be used for many applications. It is on of the fast developing sectors that can be used widely on a large scale. Due to this reason only the number of wind turbines in USA has witnessed a drastic increase in 2000.
The other competent source of energy is solar energy. The electricity harvested by the
Photo voltaic cells can be used for several purposes. It functions by converting the light energy into electricity energy. If this energy is processed judiciously, it can evolve as a treacherous threat for the electrical companies.
Geo thermal energy is one of the hardly known and discussed forms of energy. The heat trapped within the earth surface is converted into steam through proper harvesting channels. Just the way the wind turbine functions, the steam funnelled in form of geothermal energy can be effectively used to rotate the turbines. The generated power can be used for respective processes.
Another significant form of renewable energy is hydropower. The spin produced by the hydropower used in streams and turbines can be harnessed by rotation of the spin turbines, which simultaneously produce electricity. But it is very necessary to use this form of energy in a decisive way since it can harm the aquatic life.
There is an urgent need to switch over to these renewable sources of energy otherwise the global doomsday would be nearer and much more disastrous than anyone could have imagined.
Global Warming and Hybrid cars
By · CommentsGlobal Warming: Hybrid Cars
In order to face this menace, a lot of judicious steps need to be implemented. The car producers have been asked to chalk out eco friendly designs and devise out ways so that the emission of gases in the atmosphere can be controlled. After all, the contribution of vehicles in green house effects is quite apparent. Countries like USA has uncontrolled gaseous emissions that cannot even be compared with other countries.
Recently an alternative solution to reduce the effects of global warming has been devised. This concept is termed as the hybrids innovative technology. The augmented consumption of gas causes the environmental problems. It is surprising to know that the gasoline that actually weighs around six gallons, weighs twenty gallons when the carbon dioxide in it combines with water after it is burned. If a hybrid car is developed than the amount of green house gases emitted can be controlled dynamically without adding to any grave consequences.
The reason behind choosing the hybrid cars is its technical working though which the fuel emissions can be decreased. It does not use gasoline and rather runs on battery. These cars get automatically switched off when stopped. They basically work on an electric motor that aids the gasoline engine of the car. But the motor restricts the functioning of gasoline through which the fuel emission of the car gets reduced.
These cards also lower down the smog by more than ninety percent when compared to the other cards. Hence the hybrid cars have note worthy innovations when dealing with global warming. They not only limit the emissions of gases but also work on constricted consumption.
With global warming increasing its jeopardising aftermath on such a large scale, the use of hybrid cars may not be a very competent option but in spite of it, if the population adopts it’s functioning a lot can be done. In a nutshell, its contribution in curbing the numerous effects of global warming is satisfactory.

Global Warming: Recent Development
Global warming and Greenhouse effect from the historical perspectiveNowadays, global warming has emerged as one of the favorite topics of heated debates. Every man has endowed this crowd pulling moot line with different interpretations and perspectives. This attitude is necessary when the entire revolution to reduce the emission of carbon dioxide has to take place.According to historical evidences and research it has been found out around fifteen thousand years ago earth was completely covered wit ice. Though the termination of ice age came nearly seven thousand years ago, many parts of earth still had to suffer harsh and cold climatic strokes from fourteen to late nineteenth century. Due to this reason, even today this period is better signified as the little ice age.In 1924, Fourier put forward the theory, which dealt with the trapping of solar radiation in the atmosphere of earth, which later caused the warming process. After wards this phenomenon was termed as Green house effect by Arrhenius in the late nineteen century. Even Callender supported the concept of this whole effect in during 1950.Due to the harrowing effects of global warming taking far reaching platforms, there were numerous researches and attention paid to this subject. The need to devise systematic and methodical steps to control the climatic changes was felt. After a number of discoveries, researches and scrutinizing it was found that the accumulation and increase in the amount of carbon dioxide caused the phenomenon. The United Nations panel On Climate Change further stressed upon the need to curb the menace of global warming with the support from all the nations. In 1997, Kyoto Protocol, which was an international agreement, was held to discuss about this antagonizing threat to earth’s atmosphere. This agreement further made it mandatory for the countries to control their respective emissions of Carbon dioxide. This lead to many acrimonious debates and altercations and only after eight years of wait, this agreement attained its due approval from around one hundred and fourteen countries. In spite of being the largest producer of green house gases, USA and Australia did not root this treaty.The other countries that had endorsed this treaty slowly and slowly started finding it hard to follow the maintenance and control due to several political pressures and limitations of gas and oil industry. But on the other hand, there are several individual companies, which have materialized this entire concept and in fact reduced the carbon dioxide emission in a commendable way. The targets specified by the Kyoto Protocol are functioning till 2012. To derive further plan of actions a G8 meeting has been already held. |
Dangers of global warming
By · CommentsGlobal Warming: The Danger
In the late 1990’s, troposphere witnessed an increase in its average temperature by 0.4 A Fahrenheit. This process of regular increase in the earth’s atmosphere resulted into further detrimental effects that caused the scientists to research about the causes behind these climatic changes. The reckless human activities were one of the opined causes, which lead to global warming. Increase in green house effect due escalation in the concentration of the amount of green house gases especially carbon dioxide has resulted to such after effects. The amount of these gases undergoes inflation also due to the agricultural practices, land denudation and the exploitation of fossil fuels.
The projections of Intergovernmental Panel on Climate Change have revealed that during the 1990 and 2100, there would be an increase in the temperature from 2.5 –10.5AA F. since it is not practical to predict the augmentation in the percentage of green house gases in the coming years, the accurate value of the temperature increase cannot be calculated. In addition to it, the climate sensitivity is also difficult to comprehend.
There have been many grave consequences of global warming in the recent years. There has been a drastic increase in the volume and level of sea due to the continuous increase in the melting of glaciers accompanied with the irregular rainfall. These further intensify the environmental conditions through killer hurricanes, droughts, floods, tornadoes and heat waves. During the summer months, there has been apparent drying of numerous streams coupled with increase in communicable diseases has caused extinction of several species. The frequency on above-mentioned incidents has quadrupled over the years due to global warming but on the other hand, it’s not the only phenomena to be blamed. The longevity of carbon dioxide gas in the earth’s environment has been calculated to be more when compared to other gases. So the researched increase in the facts and figures of rise in the level of ocean bodies and sea is not limited only to 2010.
The process of global warming can also be termed as global cooling which took place during the ice age. Though it’s entirely natural, the human activities also have a dominating role in this ordeal due to which reason it has been chosen as the chief subject of many write-ups and research papers.
The alteration in the earth’s pathway around the sun due to the increase in the amount of carbon dioxide after the industrial revolution is termed as Milankovith cycle. The accumulation of green house gases, eruption of volcanoes, changes in solar movements and earth’s orbit of revolution are some leading causes of global warming.

Hybrid Vehicles: Maintaining Them
By · CommentsHybrid Vehicles: Maintaining Them
Recent environmental changes have created great awareness regarding nature and man’s effect on it. With regards to to their humongous popularity as environment saving cars, the sales of hybrid vehicles was bound to increase. As their hybrid nature and changed dynamics of these cars makes them different from the traditional gasoline and diesel propelled vehicles, people have quite a few questions related to the maintenance of these vehicles. In this article, we have tried to answer some of the most frequently asked questions on the maintenance of hybrid vehicles.
As most of the commercially produced hybrid vehicles are available in the electric and gasoline combination, they are more common among masses as compared to other high technological counterparts like hydrogen and methanol hybrid cars. Routine maintenance of these (gasoline hybrid) vehicles differs slightly from that of the traditional non-hybrid vehicles. These differences are very apparent in the way we deal with the systems that controls the on-board storage batteries and the additional electric motors. Otherwise, the routine maintenance of hybrid vehicles is pretty much the same as that for a non-hybrid automobile.
Conditions like light cruising and low speed maneuvering cause a hybrid vehicle to switch to electric motor for its propulsion. Therefore, we can conclude that the engine of a hybrid vehicle does not have to work very hard and thus a reduced wear and tear. Further, hybrid vehicles often use regenerative braking systems; these systems perform the dual function of charging the batteries and reducing the wear on the brake components.
As far as the maintenance of your hybrid vehicle goes, you can change out fuel, spark plugs, air filters and check the transmission fluid. While the drive train of a hybrid vehicle is significantly different from that of a traditional non-hybrid vehicle it can still be serviced, if done carefully. Further, because of the manner in which the internal combustion engine, the transmission, and the electric drive motor are mated together to work almost as one entity, a malfunction of one of these components can significantly affect the way others function perform. Therefore, any serious diagnosis, troubleshooting, and repair of this system should be left to the professionals.
If you are performing a regular maintenance on the engine cooling system of your hybrid vehicle, ensure that you check the individual clamps, hoses, and pipes. Also check the additional filters that are possibly used on the battery and motor heating/cooling system of your vehicle. Kindly leave alone the complex electronic modules that are responsible for controlling the electric drive motor of your vehicle’s propulsion and regenerative braking systems.
Hybrid vehicles are typically equipped with dual voltage systems. Although, a considerable portion of the electrical system operates at a safe standard of 12V, the drive motor and all components related to it operate better at a voltage of more than 100 V. Be careful; as the safety threshold is narrow and low, an electrical shock of even 50 V usually proves fatal. Therefore, in order to warn the operators and the technicians of these high-voltage circuits, automobile manufacturers wrap these cables in a bright orange casing. So, if you want to safely maintain and repair these orange-cased components, ensure that you first de-power the system. This is also a task that is best left to technicians who are trained to handle and maintain hybrid vehicles.
