GLOBALWARMING
Global Warming is an International Issue.
INTRODUCTION: WHAT IS GLOBAL WARMING?
The phrase global warming refers to the documented historical warming of the Earth’s surface based upon worldwide temperature records that have been maintained by humans since the 1880s. Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans. The term Global warming is often used synonymously with the term climate change, but the two terms have distinct meanings. Global warming is the combined result of anthropogenic (human-caused) emissions of greenhouse gases and changes in solar irradiance, while climate change refers to any change in the state of the climate that can be identified by changes in the average and/or the variability of its properties (e.g., temperature, precipitation), and that persists for an extended period, typically decades or longer.
Causes of global warming
GREEN HOUSE GASES: Global Warming is increasing the earth’s average temperature. The Green house gases are the main culprits of the global warming. The green house gases like carbon dioxide, methane, and nitrous oxide are playing hazards in the present times. These green house gases trap heat in earth’s atmosphere and thus result in increasing the temperature of earth. The excessive emission of these gases is the major cause of global warming.
CARBON DIOXIDE: The major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation. Coal is the major fuel that is burnt in these power plants. Coal produces around 1.7 times as much carbon dioxide per unit of energy when flamed as does natural gas and 1.25 times as much as oil. The coal gives out eighty percent more carbon per unit of energy it produces as compared to natural gas. Another major source of carbon dioxide in the atmosphere is the emission from the cars and other vehicles. About twenty percent of carbon dioxide emitted in the atmosphere comes from burning of gasoline in the engines of the vehicles. This is true for most of the developed countries. Moreover if sports bike and vehicles that are essentially designed for rough terrain, emit more carbon dioxide when used for general purpose on roads. It is always better to use vehicles designed for city driving on the city roads.

Buildings, both commercial and residential represent a larger source of global warming pollution than cars and trucks. Building of these structures requires a lot of fuel to be burnt which emits a large amount of carbon dioxide in the atmosphere.
METHANE: The second major greenhouse gas after carbon dioxide, which causes global warming, is Methane. Methane is more than 20 times as effectual as CO2 at entrapping heat in the atmosphere. Methane is obtained from resources such as rice paddies, bovine flatulence, bacteria in bogs and fossil fuel manufacture. Almost in all parts of the world, rice is grown on flooded fields. When fields are flooded, anaerobic situation build up and the organic matter in the soil decays, releasing methane to the atmosphere.
NITROUS OXIDE GAS: Nitrous oxide, which is a colorless gas with a sweet odour, is another green house gas. The main sources of nitrous oxide include nylon and nitric acid production, cars with catalytic converters, the use of fertilizers in agriculture and the burning of organic matter. Greater emissions of nitrous oxides in the recent decades is leading global warming
DEFORESTATION: Another major cause of global warming is deforestation. Deforestation is to be blamed for 25% of all carbon dioxide release entering the atmosphere, by the cutting and burning of about 34 million acres of trees each year. Trees collect the CO2 that we breathe out and give away from various other sources, and they give back oxygen that we breathe in. Thus, cutting of trees is leading to greater concentration of carbon dioxide in the atmosphere. Greater urbanization, requirement of land for factories and buildings, requirement of timber are all reasons that are leading to deforestation, which in turn is leading to global warming.

GLOBAL WARMING AWARENESS or FACTS
Global warming is caused by green house gases, which trap in the sun’s infrared rays in the earth’s atmosphere, which in turn heat up the earth’s atmosphere. These green house effect warming is called as global warming. The effects of green house effect are visible more prominently in the recent years, with number of natural calamities on the rise in the whole world.
The global warming has happened in the past few years and is evident from the rise in mean temperature of the earth’s atmosphere. The main causes for the global warming are attributed to release of green house gases by human activities. The main gases contributing to green house effect are carbon dioxide, water vapor, methane and nitrous oxide. The largest producers of these gases are the thermal power plants, which burn the fossil fuels and produce these gases in large quantities. The second biggest sources of these green house gases are the road vehicles and industries.
The global warming has led to increase in mean earth surface temperature and thus melting of polar ice. There are frequent melt down of glaciers that result in floods and other natural calamities. The melting of ice at the poles had led the mean sea level. And further increase in temperature may further melt the ice and lead to further increase in mean sea level, which will engulf low lying countries.
The effect of global warming is very evident on the animal kingdom also. Some animals have become extinct due to loss of their natural habitat or their inability to evolve to the rapid changes in the climate. Also there is a change in their life style because of the changes in the seasons. The migrating birds have changed their time of travel and also their place of migration.

The effect of global warming can be felt on seasons too. There is shift in season cycle, as the summers are getting longer than the winters. This has affected the animals and made them to change their lifestyle accordingly, and those who failed to do so have perished or on the verge of extinction.
The global warming is also responsible for the introduction of some new diseases. The bacteria are more effective and multiply much faster in warmer temperatures compared to cold temperatures. The increase in temperature has led to increase in the microbes that cause 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. Also the flash floods and other natural calamities affect the crop.
As a matter of fact, because of global warming, the earth’s atmosphere is getting more unpredictable with heavy rains in the areas, which have scanty rainfall or drought in the areas, which received good annual rainfall. The months of rainfall has also getting affected.
But there are some people on the other side of the wall also, they believe that the global warming is a natural process and cannot disturb our ecosystem. The earth’s surface mean temperature was even higher a long time ago, and the ecosystem has evolved from that temperature to this. So it can evolve further. But the changes that are happening now are rather fast compared to earlier times.
EFFECT OF GLOBAL WARMING
1. CLIMATIC CHANGE: One of the major effects of global warming is the climatic change that is being absorbed on the earth. There are floods in the areas where the flood history is not very common. There are droughts in places, which were having good rainfall earlier. The atmosphere gets suddenly very harsh in the terms of cyclones and thunderstorms. The nature of earth’s atmosphere is becoming even more unpredictable and hence a cause of attention. This in turn brings about a variation in the biological systems essentially the crops, forests, oceans, fresh waterways, and grasslands. As these are the building and breeding grounds of life, the life on earth is getting affected.

2. BEHAVIOR OF THE WILD LIFE: Another major effect of Global Warming has been noticed in the behavior of the wild life. There has been extinction of various species due to global warming. Major changes are seen in the animals as they react to the warmer environment, which are caused due to global warming. A behavior pattern of the animals studied shows that the animals are beginning to shift their population towards north or towards a higher altitudes. A simple study that was made in the university of California on a small butterfly is enough to depict the changes in the availability of species in the warmer areas. A survey at one hundred and fifty one areas showed that the butterfly were getting less populated in the southern areas which were warmer as compared to the northern areas. Hence the butterflies have migrated from warm southern zone to cooler northern zone.
3. MARINE LIFE: The marine life is also very sensitive to the increase in temperatures. The effect of global warming will definitely be seen on some species in the water. A survey was made in which the marine life reacted significantly to the changes in water temperatures. It is expected that many species will die off or become extinct due to the increase in the temperatures of the water, whereas various other species, which prefer warmer waters, will increase tremendously. Perhaps the most disturbing changes are expected in the coral reefs that are expected to die off as an effect of global warming. Even the penguins that live on poles are getting affected as a result of global warming. Due to melting of polar ice their life cycle is getting disturbed and which leads to death of many animals.
4. VEGETATION: Another effect of global warming will be on the vegetation that is available on the earth surface. The tundra type of vegetation will turn to temperate, cold deciduous and evergreen type of forest. Woody plant population will tend to increase as a result of increased precipitation. There will be a drastic change in the type of vegetation available in the area, which will in turn effect the inhabitation of the area.

5. THE GLACIERS ARE RETREATING AT AN ALARMING RATE: As an effect of global warming the glaciers are retreating at an alarming rate and changing the entire environment of the mountains. This will bring about the most intense climatic changes and alteration in the habitat. There will be a considerable increase in the water level of oceans and seas as a result of melting of glaciers. This increase in level of seas and oceans will engulf land at the coastal areas and some low lying countries may even become submerged. As an effect of global warming there are rapid temperature changes expected in the future which will affect the length of the seasons. The winter will be quite short. This will imbalance the ecosystem and will effect greatly on the behavior of the birds and the animals. This will require a drastic change in the feeding periods of young birds and the availability of food for them. These climatic changes will also impact on the growing season for the farmers. The farmers are planting the seeds according to the seasons and rain, but since the rains are getting disturbed and also the climate is getting shifted, the sowing time is difficult to predict, which will lead to poor production and hence shortage of food grains. Much of the crop is also effect by the violent nature of the atmosphere like thunder storms and cyclones.
6. SPECIES: A s an effect of global warming species like golden toad, harlequin frog of Costa Rica has already become extinct. There are number of species that have a threat of disappearing soon as an effect of global warming. As an effect of global warming various new diseases have emerged lately. These diseases are occurring frequently due to the increase in earths average temperature since the bacteria can survive better in elevated temperatures and even multiplies faster when the conditions are favorable. The global warming is extending the distribution of mosquitoes due to the increase in humidity levels and their frequent growth in warmer atmosphere. Various diseases due to ebola, hanta and machupo virus are expected due to warmer climates. The global warming is expected to cause irreversible changes in the ecosystem and the behavior of animals
