CAUSESCAUSES

• The average facade temperature of the globe has The average facade temperature of the globe has augmented more than 1 degree Fahrenheit since augmented more than 1 degree Fahrenheit since 1900 and the speed of warming has been almost 1900 and the speed of warming has been almost three folds the century long average since 1970. three folds the century long average since 1970. This increase in earth’s average temperature is This increase in earth’s average temperature is called Global warming. More or less all specialists called Global warming. More or less all specialists studying the climate record of the earth have the studying the climate record of the earth have the same opinion now that human actions, mainly the same opinion now that human actions, mainly the discharge of green house gases from discharge of green house gases from smokestacks, vehicles, and burning forests, are smokestacks, vehicles, and burning forests, are perhaps the leading power driving the fashion. perhaps the leading power driving the fashion.

• The gases append to the planet's normal greenhouse The gases append to the planet's normal greenhouse effect, permitting sunlight in, but stopping some of effect, permitting sunlight in, but stopping some of the ensuing heat from radiating back to space. Based the ensuing heat from radiating back to space. Based on the study on past climate shifts, notes of current on the study on past climate shifts, notes of current situations, and computer simulations, many climate situations, and computer simulations, many climate scientists say that lacking of big curbs in greenhouse scientists say that lacking of big curbs in greenhouse gas discharges, the 21st century might see gas discharges, the 21st century might see temperatures rise of about 3 to 8 degrees, climate temperatures rise of about 3 to 8 degrees, climate patterns piercingly shift, ice sheets contract and seas patterns piercingly shift, ice sheets contract and seas rise several feet. With the probable exemption of one rise several feet. With the probable exemption of one more world war, a huge asteroid, or a fatal plague, more world war, a huge asteroid, or a fatal plague, global warming may be the only most danger to our global warming may be the only most danger to our planet earth planet earth

• As said, the major cause of global warming is the As said, the major cause of global warming is the emission of green house gases like carbon dioxide, emission of green house gases like carbon dioxide, methane, nitrous oxide etc into the atmosphere. The methane, nitrous oxide etc into the atmosphere. The major source of carbon dioxide is the power plants. major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the dioxide produced from burning of fossil fuels for the purpose of electricity generation. About twenty purpose of electricity generation. About twenty percent of carbon dioxide emitted in the atmosphere percent of carbon dioxide emitted in the atmosphere comes from burning of gasoline in the engines of the comes from burning of gasoline in the engines of the vehicles. This is true for most of the developed vehicles. This is true for most of the developed countries. Buildings, both commercial and residential countries. Buildings, both commercial and residential represent a larger source of global warming pollution represent a larger source of global warming pollution than cars and trucks. than cars and trucks.

• Building of these structures require a Building of these structures require a lot of fuel to be burnt which emits a lot of fuel to be burnt which emits a large amount of carbon dioxide in the large amount of carbon dioxide in the atmosphere. Methane is more than 20 atmosphere. Methane is more than 20 times as effectual as CO2 at times as effectual as CO2 at entrapping heat in the atmosphere. entrapping heat in the atmosphere. Methane is obtained from resources Methane is obtained from resources such as rice paddies, bovine such as rice paddies, bovine flatulence, bacteria in bogs and fossil flatulence, bacteria in bogs and fossil fuel manufacture. When fields are fuel manufacture. When fields are flooded, anaerobic situation build up flooded, anaerobic situation build up and the organic matter in the soil and the organic matter in the soil decays, releasing methane to the decays, releasing methane to the atmosphere. The main sources of atmosphere. The main sources of nitrous oxide include nylon and nitric nitrous oxide include nylon and nitric acid production, cars with catalytic acid production, cars with catalytic converters, the use of fertilizers in converters, the use of fertilizers in agriculture and the burning of organic agriculture and the burning of organic matter. Another cause of global matter. Another cause of global warming is deforestation that is warming is deforestation that is caused by cutting and burning of caused by cutting and burning of forests for the purpose of residence forests for the purpose of residence and industrialization. and industrialization.

The scientists tell us that cause increases in earth’s temperature. The scientists tell us that the tundra is in danger of melting holds an amount of extra global the tundra is in danger of melting holds an amount of extra global warming pollution that is equivalent to the net amount that is warming pollution that is equivalent to the net amount that is previously in the earth's atmosphere. Likewise, earlier one more previously in the earth's atmosphere. Likewise, earlier one more team of scientists reported that the in a single year Greenland team of scientists reported that the in a single year Greenland witnessed 32 glacial earthquakes between 4.6 and 5.1 on the witnessed 32 glacial earthquakes between 4.6 and 5.1 on the Richter scale. This is a disturbing sign and points that a huge Richter scale. This is a disturbing sign and points that a huge destabilization that may now be in progress deep within the destabilization that may now be in progress deep within the second biggest accretion of ice on the planet. This ice would be second biggest accretion of ice on the planet. This ice would be enough to raise sea level 20 feet worldwide if it broke up and enough to raise sea level 20 feet worldwide if it broke up and slipped into the sea. Each day passing brings yet new proof that slipped into the sea. Each day passing brings yet new proof that we are now in front of a global emergency, a climate emergency we are now in front of a global emergency, a climate emergency that needs instant action to piercingly decrease carbon dioxide that needs instant action to piercingly decrease carbon dioxide emissions worldwide in order to turn down the earth's rising emissions worldwide in order to turn down the earth's rising temperatures and avoid any catastrophe. temperatures and avoid any catastrophe.

• It is not easy to attach any It is not easy to attach any particular events to global particular events to global warming, but studies prove warming, but studies prove the fact that human the fact that human activities are increasing the activities are increasing the earth’s temperature. Even earth’s temperature. Even though most predictions though most predictions focus on the epoch up to focus on the epoch up to 2100, even if no further 2100, even if no further greenhouse gases were greenhouse gases were discharged after this date, discharged after this date, global warming and sea global warming and sea level would be likely to go level would be likely to go on to rise for more than a on to rise for more than a millennium, since carbon millennium, since carbon dioxide has a long average dioxide has a long average atmospheric life span. atmospheric life span.

• But an interesting side of the global warming But an interesting side of the global warming episode is that there are people who do not episode is that there are people who do not consider global warming as something that is consider global warming as something that is creating a problem. Skeptics of global creating a problem. Skeptics of global warming think that global warming is not an warming think that global warming is not an ecological trouble. According to the global ecological trouble. According to the global warming skeptics, the recent enhancement in warming skeptics, the recent enhancement in the earth's average temperature is no reason the earth's average temperature is no reason for alarm. According to them earth's for alarm. According to them earth's coastlines and polar ice caps are not at a risk coastlines and polar ice caps are not at a risk of vanishing. Global warming skeptics of vanishing. Global warming skeptics consider that the weather models used to consider that the weather models used to establish global warming and to forecast its establish global warming and to forecast its impacts are distorted. According to the impacts are distorted. According to the models, if calculations are made the last few models, if calculations are made the last few decades must have been much worse as decades must have been much worse as compared to actually happened to be. Most compared to actually happened to be. Most of the global warming skeptics believe that of the global warming skeptics believe that the global warming is not actually occurring. the global warming is not actually occurring. They stress on the fact the climatic They stress on the fact the climatic conditions vary because of volcanism, the conditions vary because of volcanism, the obliquity cycle, changes in solar output, and obliquity cycle, changes in solar output, and internal variability. Also the warming can be internal variability. Also the warming can be due to the variation in cloud cover, which in due to the variation in cloud cover, which in turn is responsible for the temperatures on turn is responsible for the temperatures on the earth. The variations are also a result of the earth. The variations are also a result of cosmic ray flux that is modulated by the solar cosmic ray flux that is modulated by the solar magnetic cycles. magnetic cycles.

There are various benefits of global warming There are various benefits of global warming according to them. According to the skeptics, according to them. According to the skeptics, the global warming will increase humidity in the global warming will increase humidity in tropical deserts. Also the higher levels of tropical deserts. Also the higher levels of carbon dioxide in the atmosphere trigger carbon dioxide in the atmosphere trigger plant growth. As predicted, due to the global plant growth. As predicted, due to the global warming the sea levels will rise. But this can warming the sea levels will rise. But this can be readily adapted. Another argument of be readily adapted. Another argument of global warming skeptics is that earth has global warming skeptics is that earth has been warmer than today as seen in its been warmer than today as seen in its history. The thought is that global warming is history. The thought is that global warming is nothing to get afraid of because it just takes nothing to get afraid of because it just takes us back to a more natural set of environment us back to a more natural set of environment of the past. Animals and plants appeared to of the past. Animals and plants appeared to do just fine in those eras of warm climate on do just fine in those eras of warm climate on the earth. According to few skeptics, the the earth. According to few skeptics, the present chilly climate on the earth is an present chilly climate on the earth is an abnormality when judged over the abnormality when judged over the geographical scale. Over geologic time, the geographical scale.
