Global warming refers to a term in which earth’s temperature is gradually increasing causing adverse effects. Global warming is the regular increase in the atmospheric temperature of the earth, causing equivalent changes in the temperature and that may be the result from green house effect. Many opinions are given about the global warming. It is said that global warming is good but to some extent. The increase in global warming is about 13 % which is too much and have many side effects.

Scientists have given many opinions about global warming and about how to reduce global warming. The opinion given by scientists is through a synthesis report. Many individual scientists, students and universities and laboratories have contributed to the opinion about global warming

Synthesis reports are appraisals of the scientific literature that compile the results of standalone studies’ range to attain a certain level of understanding. The earth’s climate is adversely affected by the production of green house gases from human commotions. These green house gases change the atmosphere of the earth and make it worse. The gases like carbon dioxide, methane as well as nitrous oxide etc. are called green house gases. These gases are emission when fossil fuels are flamed and also when many industrial and agricultural processes take place and are never desirable, even when on the HCG diet plan. After trying the HCG diet I was a believer! All these evidences are indisputable and global warming is occurring. According to scientific opinion about global warming, if no certain actions are taken, then momentous disturbances will take place in the physical and ecological systems, social systems, security and human health on the earth are expected to take place. Emissions of green house gases must be reduced in order to prevent global warming.

The changes that are observed during the last past decades are mostly due to the reasons of human activities but no one can deny the truth that there are also some natural causes of global warming. Nature creates the natural causes. There are many natural causes for global warming. One is the release of methane from arctic tundra and wetlands. There is widespread recognition that the climate, irrespective of the cause id changing. The finding that the climate has warned in recent decades and that human activities are already contributing adversely to global climate changes has been endorsed. There is debate about fossil fuels consumption.

There found convincing evidence that since the development of industries, the activities of human beings have increased the combination of green house gases in to the atmosphere which is the major agent of change in the climate. These gases of the green house affect the global climate in many ways. They maintain heat in the atmosphere and do not let it escape from the earth. Thus, the temperature of the earth’s climate increases and alters rainfall patterns and also changes atmospheric climate.

While, different steps are needed to reduce global warming on national and international levels, it is also needed to reduce the amount of green house gases in the atmosphere. People are solution oriented and proper steps should be taken to reduce global warming.

Global warming refers to the current ascend in Earth’s temperature due to gradually increasing absorption of manmade green house gases like carbon dioxide production from the flaming of fossil fuels or from deforestation. Carbon dioxide traps heat and do not allow it to escape the Earth. It is also known as green house effect.

According to the viewpoint of scientific methods, the global warming is a cause of human activities such as pollution that contains a lot of Sulphur dioxide and carbon dioxide. Water vapor is one of the most considerable gases of the green house. Even a small increase in the level of atmosphere of carbon dioxide, can cause extensive increase in the atmospheric temperature of Earth. There are two main constituents of the atmosphere that is, oxygen and nitrogen. Oxygen and nitrogen are not the gases of green house. The reason for which oxygen and nitrogen are not the gases of green house is that, both the gases have two molecules and thus they lack vibration modes that molecules consisting of more than two atoms comprise. Carbon dioxide has the characteristic that it remains inside the atmosphere for a long period. Water vapor, being the green house gas, can easily evaporate on any local temperatures. Thus, water vapor easily adjusts in the customary conditions.

Humanity has increased the amount of carbon dioxide in the atmosphere to about 13 %, and it is an extremely significance increase. This causes the global warming to increase. Human beings are considered the main reason of increase in global warming to this extent as, the increase in the global warming is perfectly associated with the increase in the burning up of fossil fuels.

The result of increased atmospheric temperature has adverse effects on the Earth and the human beings living on it. In fact, the global warming will have influential effects on our planet. Warming amend rainfall patterns, increase soil erosion, extend the growing seasons in some areas or countries, dissolve ice caps and glaciers, and also change the assortment of some infectious diseases. The global warming will result in more frequent hot days and fewer cold days. The intense heat waves from the sun will be become more common. Natural destruction will become more common and severe such as storms, floods and droughts as the rainfall patterns alter.

The effects of global warming are not limited to the weather; seas levels will also be affected. The sea levels will start rising and will corrode coasts and will cause more coastal flooding.  Significantly, global warming will adversely affect the ecosystems. The plant and animals that are living in the atmosphere both land and in the oceans are greatly affected by the adverse affects of global warming. Warmer temperatures have already shifted the cooler temperatures in some areas. The change in growing seasons have been effected the globe. In some communities, the daily temperature has become unbearable to some plants and animals. Eventually, the global warming will affect the life on Earth in many different ways.

Polar ice caps are high autonomy region of a planet that is covered with ice. There are no special requirements for size and composition for a body of ice to be called as polar ice cap. The composition of ice on the polar ice caps varies. Polar ice caps are found in the polar region where the sun light reaches rarely. Due to the rare sun light ice caps are formed in the Polar Regions so, the ice caps are called polar ice caps. The temperature in the Polar Regions is below zero degree. The polar ice caps on the Earth have noticeably altered over last 12,000 years. Varied solar energy absorption is the cause of seasonal distinction of the polar ice caps as the moon and our planet, Earth rotate around the Sun.

Earth’s North Pole is enveloped by floating packs of ice on the Arctic Ocean. The portions of ice caps which do not melt seasonally get very thick. These can be thick up to 3 – 4 meters over large areas. The ice of one year is an approximately 1 meter thick. The sea ice covers 9 to 12 million km square area.

On the South of the Earth, there is Antarctica, which is covered by Antarctic ice. Antarctica covers about 14.6 million km square area and the Antarctic ice covers 23 to 25 million km cube area. This ice sheet contains a lot of fresh water and hence about 70 % of the fresh water on Earth ate held in it. The temperature on Antarctica is below zero degrees centigrade. Human beings can not survive in this area as it is too cold for any type of life in it. Only animals that are cold blooded, can survive in this area. The most common animal found in Polar Regions is Polar Bear.

In the Greenland and Antarctica, there are spots that are actually gaining ice due to the increase in yearly snowfall. But these polar ice caps are melting at a very fast rate. Sometimes the melting rate becomes too slow but later on it gets speed.

The high temperature of the earth cause many polar ice caps to melt, but it do not make the oceans to raise. Polar ice caps are large suspended blocks of ice. Water is more solid at 4 degree Celsius. Below this rate the solid will start melting. The melted ice called water then falls into the river and the rivers collectively form the oceans. In the Polar Regions water is most fresh. The heat of the sun light allows the ice to melt and make water. These rivers can water the crops also as the water is too fresh and cold. The water from the polar ice caps save the surface from soil erosion. In the North Pole the ice not as thick as in the South Pole. The main land that is covered with ice is Antarctica. It is the most coolest place and human beings can not survive in such climate.

Global warming refers to the gradual increase in the earth’s temperature due to the emission of green house gases such as carbon dioxide, methane, nitrous oxide and other dangerous gases. Global warming refers to a challenge for human beings. Global warming causes ozone depletion. Ozone is the layer that protects the earth from ultra violet radiations coming from the sun. Global warming is continuously damaging the ozone layer that is a very dangerous thing for earth.

It is very important to reduce global warming, as it is good to some extent. If no certain steps are taken, then earth will have to face undisputable circumstances. To reduce global warming proper steps should be taken in order to prevent the earth from such certain circumstances. To reduce globing warming following steps can be taken:

1. By reducing gasoline consumption, we can reduce global warming as 20 gallons of carbon dioxide is released when gasoline is consumed, so take bike, walk, use public transportation and reduce the usage of gasoline to prevent global warming.
2. Try to drink shade frown coffee. Sun grown coffee is produced in the areas of devastated rainforests, while shade grown coffees help in preserving the rainforests. People should reduce the use of pesticides which are eventually beneficial for our planet.
3. Support green hostels. When people travel, they should stay at green hotels in which the owners have programs that save energy and water and reduce solid waste. It will ultimately reduce global warming.
4. People should adult their home that is: people should get a free energy adult on their homes from their das and electricity utility and then institute their recommendations.
5. People should eat more vegetables than meat. The average diet causes the release of 1.5 tons of green house gases per year compared with a strict plan based diet. Reduce your meat and dairy intake by half which can make a big difference. It will also global warming to reduce.
6. Make saving energy a family affair. Assign each person an energy saving task in your family. This will cause the global warming to be reduced.
7.  Re energizes your office. Help institute of energy to save energy. In this way the goal of reducing global warming will be achieved.
8. People should defrost their refrigerator and freezers on daily basis.
9. Do your part to reduce waste by choosing reusable products instead of disposable. Buying products with minimal packaging will help to reduce waste. And whenever you can recycle paper, plastic, newspaper, glass and aluminum cans.
10. People should use less heat and air conditioning. Adding insulations to your walls and attic, and installing weather stripping or caulking around doors and windows can lower your heating costs more than 25 %., reducing the amount of energy you need to heat or cool your home.
11. People should change their light bulbs. Wherever practical, replace light bulbs regularly with CFL bulbs.
12. People should drive less and drive smart.

Global warming is the phenomenon in which the earth’s temperature keeps on increasing gradually due to the man made green house gases such as carbon dioxide and Sulphur dioxide. Carbon dioxide is produced by many ways like by flaming fossil fuels or by deforestation etc. Carbon dioxide absorbs the heat radiations coming from the sun and does not the heat radiations to escape from the earth. Man has increased the amount of Carbon dioxide in the atmosphere to about 13 %. This is an extensively large percentage as the earth keeps on getting hot.

Global warming is caused due to many factors. These causes are segregated in to two groups that are manmade causes and natural causes. Nature creates the natural causes. There are many natural causes for global warming. One is the discharge of methane gas from arctic tundra and wetlands. As we know that methane is a green house gas so it traps the heat radiations from the sun in the earth and does not allow them to escape. This causes global warming. The other natural cause of global warming is the fact that earth passes through a number of climatic changes and the climate change lasts for about 40,000 years.

The most damage is caused by manmade factors that cause global warming. There are several man made factors to cause global warming. The one of the biggest cause among man made causes is pollution. Pollution has many shapes and sizes and it causes a lot of damage to the earth’s atmosphere. Flaming of fossil fuels is the cause of pollution as well as of global warming. As, when fossil fuels are flamed, they release a green house gas which is called carbon dioxide. It absorbs heat from the sun and cause global warming. Mining coal and oil also allows methane gas to escape. Methane exists naturally inside the ground. When oil or coal is mined, the earth is dug up a little and also allows methane to escape. When fossil fuels are dug they also allow methane to escape. In this way, global warming is caused.

Population is the other man made cause of Global warming. As more people needs more food and more needs of transportation. For making food, fossil fuels are flamed and agriculture is done which causes more methane. Manure is the other source of methane. As food is needed in a bulk quantity for huge population, food factories and crops are raised. Many animals such as cow are also a source of food which cause more manure and release more methane. Transportation is another problem, when population increases. Huge population means, more cars, vehicles and more population. As carbon dioxide promotes the global warming, increase in population plays a vital role in promoting global warming, as human beings breathes out carbon dioxide and inhales oxygen. These cause more carbon dioxide to release in the atmosphere and cause global warming. The trees inhale carbon dioxide, released by human beings, are also demolished which also cause global warming.
