Global warming is a growing phenomenon around the world that we live in. As usual, when it came about, the world proceeded to panic. Then over decades people began to wonder more about global warming. “What exactly is global warming?” “Where is it from?” Now global warming seems to be just another theory that scientist have come up with. The purpose of this project is to research and discover how real global warming is. Is it as real and serious as society makes it out to be or is it just a hypothetical for something else? That is what I want to find out. I believe that climate change is a very real thing but I just don’t know about global warming.
`Global warming is a term used to describe a jump in climate and temperatures over time. There have been three periods of global warming since 1850. They are from 1860 to 1880, 1915 to 1945, 1975 to 1998, and all the way up to the current times. Most recently the warming temperatures have been traced back to emissions given off by the transportation that humans use. Each period of warming was separated by a period of global cooling. The warming and cooling cycles, and their changes in precipitation patterns are called climate change. Climate change has been occurring for the past 11,000 years since the last ice age. Recent research has shown that this steep curve is probably a product of what is known as the heat island effect rather than the global warming that everyone else thinks it to be.

Global warming has been studied extensively and has been concluded that global warming comes from a hole in the ozone layer from gases like carbon dioxide, methane, nitrous oxide, etc. Global warming is said to be started by too many greenhouse gases being exposed to the air. Once in the air the greenhouse gases form almost a dome that traps more hot air in the atmosphere. The most serious gas of the set is CO2 or Carbon Dioxide. Carbon dioxide is the most serious because it is also the most frequent gas to get into the air. When humans breathe out they contribute CO2 buildup into the environment. Cars also emit carbon dioxide into the air as they burn gasoline and drive around. Humans are pouring carbon dioxide into the atmosphere so fast that plants and oceans can’t absorb it before even more comes. Burning fossil fuels can cause so much damage to the plants and animals and everything around us. Fossil fuels produce massive amounts of CO2. CO2 is certainly the biggest contributor of global warming. It is responsible for roughly eighty-five percent of the world’s greenhouse gas problem. Obviously the biggest and most popular way to burn fossil fuels is to drive around in a gasoline powered car as those are about twenty percent of the United States’ greenhouse gases right there. Even if emissions got eliminated right now, gases would still stay in the air for years so it would take long to stop global warming or climate a change completely.

Usually the first thing that somebody thinks of with global warming is that humans cause it. Whether they are constantly relying on automobiles or if it’s the over use of the nature that was given to us. But the truth is that it’s not all humans. In fact about a quarter of the methane in the air comes from ruminants and livestock. Methane or CH4 is the second most frequent emission given off into the air. Methane is emitted from a number of sources. The most significant are agriculture, animal digestive systems and manure management, landfills, oil and gas production, and coal mining.
Agriculture is responsible for approximately fourteen percent of the world’s greenhouse gases that hurt the environment. The world’s 1.5 billion cows and billions of other grazing animals emit dozens of polluting gases including plenty of methane. The digestive system alone of cattle and animals of that source will eventually emit some methane. The food that they are being fed just kind of moves along the process. Nowadays scientists have said that
