A fuel cell is defined as an electrochemical conversion device which converts energy from fuel into electricity. It has fuel on the anode side and an oxidant on the cathode side. These two react in the presence of an electrolyte and produce electricity. A very big advantage of fuel cells is that they can be used continuously for long durations if the flows are maintained at desired levels.

Scientists are reporting development of a fuel cell that uses pollution from coal and metal mines to generate electricity, solving a serious environmental problem while providing a new source of energy. They describe successful tests of a laboratory-scale version of the device in a new study. So from here we can conclude that fuel cells are environment friendly device as it converts coal and other metal pollution into useful electricity.

The exhaust of the fuel cell is water molecule as hydrogen and oxygen molecule combine during process and concludes to water molecule. Depending on the weather conditions produced steam may rise and form clouds around the road, or it may form fog at the road surface, or it may condense and drop on the road. Even in warm weather water on the road will be dangerous. In freezing weather it will make the road downright treacherous, especially if most or all vehicles on the road are powered by hydrogen fuel cells.

The only problem occurs so far is the generation of large amount of heat as the motor vehicle working on fuel cell technology emitting more heat than other vehicles do. So this is the issue to be debate upon as in next decades the percentage of these vehicles increases leads to increase the temperature of the surroundings and then that of the earth atmosphere but one is for sure that is technology, right now, is in its earlier stage and in near future this problem will be over come by the Engineers.

But with the passage of time the problems will come and then will be overcome as this field is continuously in progress and will lead to great inventions as well as comes up with new facts and discoveries. Fuel cell technology is now applied in automobiles sector like new water car is manufactured and trains are going to crawl on this technology in future. We very well know that most of pollution is been caused by automobiles and if these are working on fuel cell technology then how much amount of carbon dioxide can be removed for atmosphere leads to obsolete the effects of Global Warming.

So now to conclude, for global warming the key ingredients are carbon dioxide and methane and both are not involved in this fuel cell technology as the waste comes out is water molecule and we all know that water is essential for living and that’s why never pollutes the environment. So fuel cell makes no pollution except one that is the generation of excessive heat energy by the automobiles and so it adds little (but that too can be manage) to global warming.

The main cause of global warming is green house effect and the gases involving in green house effect are carbon dioxide, methane, sulphur dioxide and nitrous oxide. These gasses are the playing hazards in recent times and thus result in increasing the temperature of earth.

Natural Resources like carbon dioxide, methane entrap heat in the atmosphere. Methane is obtained from rice paddies, bacteria in bogs bovine flatulence, fossil fuel manufacture and many more such kind of resources. When rice is grown on flooded fields, anaerobic situation build up and the organic matter in the soil decays, releasing methane to the atmosphere. Nitrous oxide, which is a colorless gas with a sweet odour, is another green house gas.

Other cause is deforestation, trees helps in reducing the percentage of carbon dioxide gases during there respiration. So by cutting trees, consumer for carbon dioxide will not be available thus causing increment in the percentage of carbon dioxide and other harmful gases. Facts said about quarter percent of carbon dioxide increases due to burning of wood and coal. Because while burning of wood and coal oxygen is consumed and carbon contents are released in the atmosphere like carbon dioxide, carbon monoxide and other carbon contents.

Artificial Resources like emission of gasses through automobiles and industries. These are the major source of producing the carbon dioxide as well as other gasses like sulphur dioxide, nitrous oxide, cars with catalytic converters, the use of fertilizers in agriculture and the burning of organic matter which will further increase the temperature of earth. The percentage of these gasses increased in the recent decades leads to global warming.

Other factor comes in account is the burning of the waste from houses by the sweeper which includes raw waste vegetables scrap and polythenes and other harmful material. This material while burning produces lots of harmful gases like sulphur dioxide, nitrogen oxide, carbon monoxide, carbon dioxide, etc which causes global warming.

City gridlock means traffic lock. As we all are familiar with the traffic jams because of there common occurrence. Survey shows that people stuck in traffic jams never switch of there engines and which leads to consumption of gallons of fuel. This fuel after combustion produces tones of carbon dioxide as well as contents of sulphur oxide and carbon monoxide, which further increases pollution thus leads to global warming.

The tree less plains in arctic and sub arctic which is also known as Tundra is a sink which contains billion tones of carbon in frozen state. This frozen carbon is now begins to convert into carbon dioxide in tremendous amount. This is because of the increasing temperature of earth leads to melting of frozen carbon which further converted into carbon dioxide. This is what we called as man’s biggest blunder to carbon dioxide source alive.

Use of the chlorofluorocarbon product which react with our ozone layer as well as increases the amount of carbon dioxide in atmosphere. This is present in our deodorants and other cosmetics products and some household products. So the products should be banned or should be in limited use.

Global warming will result in the average temperature going up. This will cause sea levels to rise as the glaciers melt. Large areas of occupied land may disappear. Global weather patterns will change. For example, some regions may become prone to deadly storms. Rainfall patterns will change resulting in many areas becoming deserts and others converted into swamps due to excess rainfall. This will affect global agricultural output. Poor areas will experience famines and droughts. Millions may die due to starvation. Certain types of diseases will spread and all the accumulated affects may lead to mass extinction of many animal species.

Due to global warming the temperature of earth atmosphere increases to 2 degree every decade and will go on due to excessive emission of carbon dioxide gas. Leads to melting of polar ice causes invitation to other natural calamities like floods etc and also increases the sea water level. The further increase in the temperature leads to increase in the mean sea level causes engulf the low lying countries across the world.

Effect of global warming can also be seen on the animal kingdom as some animal species become extinct due to the loss of there natural habitat or inability to resist with frequent changes in the climate conditions especially the migratory birds which are seasonal and want colder environment for their survival. These birds help in seeding as well as planting the new trees by there eating habits.

Seasonal conditions are too affected by global warming like now days summers are getting longer than winters and even the rainfall become unpredictable. Now the behavior of monsoons become random as when it is required to have rainfall then there is nothing but when at the time of harvesting of crops, no rain is required then thunderstorms occurs. This also causes floods and other storms like the one in tsunami.

Introduction to new diseases due to global warming as bacteria becomes more efficient and thus replicates in faster rates in warmer temperature. Cold and viral are the two common diseases which transmit in very faster rate due to unpredictable weather conditions. These are called communicable diseases.

Global warming is also effecting the crop production, as the crops are getting destroyed by the sudden change in temperatures or sudden on set of rains. Mid latitude forests will experience decreased rainfall and an increased risk of drought, which in turn would allow forest fires to occur on larger scale, and more regularly. This releases more stored carbon into the atmosphere than the carbon cycle can naturally re-absorb, as well as reducing the overall forest area on the planet, creating a positive feedback loop.

Water scarcity: – Sea level rise is projected to increase salt-water intrusion into groundwater in some regions, affecting drinking water and agriculture in coastal zones. Increased evaporation will reduce the effectiveness of reservoirs. Increased extreme weather means more water falls on hardened ground unable to absorb it, leading to flash floods instead of a replenishment of soil moisture or groundwater levels. In some areas, shrinking glaciers threaten the water supply.

Since global warming is seen as a result of increased production of green house gases, an effective solution to the problem is to reduce the amount of green house gases produced. This can be done by switching over to clean energy sources, ones that do not produce green house gases. Examples of clean energy sources are solar energy, wind energy, hydroelectric power and so on. Automobiles should be made fuel efficient and use energy from clean sources. The design of hybrid cars is a step in this direction. The reliance on fossil fuel must be reduced in all areas. Active research should be encouraged in the use of clean energy sources. The practice of energy conservation must be made mandatory.

Global warming is a serious issue these days. With the increase in the use of automobiles as well as work load in industries this issue really needs to be considered. Well the key factor of producing the Global warming effect is carbon dioxide gas as well as methane gas and to control Global warming one has to control the emission of these gasses.

For this issue to be resolved at the earliest one should use the proper measures like proper checking of automobile pollution and major one is to shift over swiftly to renewable sources as source of energy like Solar energy, Wind energy etc instead of using coal and wood. Solar energy is used in many fields like in generation of electricity, used in automobiles for transportation etc.

Grow more tree so as to reduce the percentage of carbon dioxide in the atmosphere because trees during respiration inhale carbon dioxide and exhale oxygen which means that its is the cheapest way to reduce the percentage of carbon dioxide and increase the amount of oxygen. Government should take proper measures to protect trees as well as should take efforts in planting more trees by making public parks or environment parks.

Prohibiting green leaves broken from branches of trees, to burn by some uneducated gardeners as this increases the amount of carbon dioxide in atmosphere. Those leaves should be buried under soil so that it helps in improving the fertility of the soil.

Use cars and light trucks that get good gas mileage. In fact driving a sports utility vehicle adds to global warming and pollution. SUVs emit 40% more global-warming pollutants (28 pounds of carbon dioxide per gallon) and 50% more air pollution than the average car. An SUV is 4 times as likely to rollover in an accident. If car manufacturers were to increase their vehicle’s average gas mileage about 3 miles per gallon, country could save a million barrels of oil every day, thus reduces the oil costs annually.

Wind power is an abundant, clean and affordable alternative to coal and other fossil fuels and the cost of wind energy is now less than that of coal. The direct cost of energy from large wind turbines has dropped to three to four cents per kilowatt-hour, comparable with that from new pulverized coal power plants.
