The atmosphere is something that is around us everyday, but do we really think about the changes that occur in it. It isn't that we just aren't paying attention, but more of the fact that it is hard to notice slight changes over long periods of time. Everyday gases are released into the air by all living material. The gases in the air are used for many important things, For example, hydrogen is released by volcanoes, which can give energy to the cell; photosynthesis has evolved to take the gas carbon dioxide and create food and release oxygen; nitrogen is a gas used in our air, oceans, and solid earth, as an essential part of living things.
Carbon dioxide is also involved in processes where it is stored as limestone and marble, as gas and oil and coal, and is in organic material in the soil. Not only do these gases make up our atmosphere, but they also keep the temperature of the earth stable. Carbon dioxide absorbs the radiation that would otherwise escape the earth. By adding oxygen and taking away carbon dioxide this causes the earth to be cooler than it would otherwise be. These are just two of the many gases that make up the atmosphere we live in today.
The temperature in our earth is directly determined by these five gases. It not enough are in the air, then the earth is too cold, but if too many gases are released into the air, then we have the problem of things heating up. Even though the causes of global warming are known, the exact effects it will have on us in the future are yet to be determined. People need to understand that they need to act now in order to keep the world as we now know it the same in the future.
The earth's atmosphere is made up of five layers of gases that act as a blanket covering the earth. This Blanket keeps in some of these gases to keep the planet warm. It is called Greenhouse Effect. This is because it acts like greenhouse windows by letting in sunlight to warn the surface and air, and hold in most of the solar generated heat. The greenhouse gases are Carbon dioxide, methane, oxygen, nitrogen, ozone and water vapor, as well as other atmospheric gases. These greenhouse gases cause the greenhouse effect by capturing and absorbing solar energy. For without the greenhouse effect, the planet would be inhospitable to life because the surface temperature of earth's surface would be cooler by 63 degrees F. This word mean the average temp would be 19 degrees C which causes the earth to be barren.
Many scientists believe that the increase in temperature is caused by humans. The greenhouse effect increases because of the burning of fossil fuels such as natural gases, oil, and coal. These cause more heat to be trapped in the atmosphere than needed. Carbon dioxide is the most important gas that humans have affected. It has increased by nearly 30% since 1700 because of human destruction's. The amount of fossil fuels we burn each year has increased dramatically.
Between 1850 and 1950, 60 million tons of fossil fuel were burned. Now the world burned. Now the world burns at least five billion tons of fossil fuel each year. This means that we are adding b/w 15 and 20 billion tons of carbon dioxide into the atmosphere every 12 months. This is causing a steady increase of carbon dioxide into our air.
Another way humans increase the amount of carbon dioxide is by deforestation. Huge numbers of trees are cut down each year to clear land for farming and building. The rainforest are really needed because they absorb carbon dioxide and release oxygen into atmosphere. Also, when trees decay or are burned, the carbon dioxide that was absorbed is put back into the air. George M. Woodwell Kilaparti Ramakrishnan said, "Deforestation is a second biggest source of carbon dioxide,..... only the burning of
Oil and Gas produce more,... If [global warming] is to be slow the World must not only stop cutting in burning large forest, but replace the many millions of acres that have been destroyed." Deforestation is the most severe in tropical regions where rainforest grow. Most of the rainforest around developing countries. The people of these countries have to find a way to get land, buy food, and get money. The only way they know how is to go into these forests in clear land to create more space for farms.
More recently, The amount of rainfall is destroyed each year is causing attention. 33 acres of rainforests are chopped or burned down every minute, and up to 25% of world's species will be extinct by the next century. The great Plains that we have now were once one enormous forest before the Europeans settled. It is said that if deforestation continues at its current rate, all of the world's forests could be destroyed within only a few decades.

Anonymous:
As the temperatures continue to increase, many more changes will occur. Mountain glaciers will melt, well as the great masses of ice anas know that cover Greenland and Antarctica. As the snow melts, large amount of water will fill the ocean. This will raise sea level by many feet and lead to the decline of living habitat.
Hence, we should show our concern for this and should take anti-global warming measures.
Thanks @Snehitha2
Writing a blog eh?
thanks :)..helped me a lot !
welcome !
@tanishqsingh! kind of :p

Answer:
Explanation:
Global warming
Global warming is a part of climate change and is partially caused by increased greenhouse gases from burning of fossil fuels, deforestation, agriculture, and other industrial causes.
The Earth's temperature had already warmed by 1°C compared to pre-industrial levels. This temperature rise may appear small, but small rises in temperature translate into big changes for the world’s climate. This is because the amount of extra energy needed to increase the world’s temperature, even by a little, is vast. This extra energy is like force-feeding the global climate system.
·Hotter days
·Rising sea level
·oceans are warming
Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the risk of wildfires in the American West.
Rising sea levels will lead to coastal flooding on the Eastern Seaboard, especially in Florida, and in other areas such as the Gulf of Mexico.
Allergies, asthma, and infectious disease outbreaks will become more common due to increased growth of pollen-producing ragweed, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes.
