However, as years have passed, global climate change is a transition that is affecting people and the world; yet, humans have only contributed towards the increment of this problem.

This leads to the growing debate of today, is global warming man-made? Or is it just a cycle that the Earth goes through?
Greenhouse gases affect the Earth’s climate by increasing the greenhouse effect, which is a natural phenomenon whereby water vapor, CO2, and other gases in the atmosphere allow sunlight to pass through, but then absorb much of the heat from the earth that otherwise would have escaped to outer space. Without the natural greenhouse effect, the mean temperature would be about minus 18°C, and the Earth would be uninhabitable
Emitting greenhouse gases in large amounts increases the concentration of these gases in the atmosphere, which then increases the greenhouse effect so that more heat is trapped by the atmosphere. This can increase the temperature of the atmosphere and change the climate on Earth.
Probably the most harmful contaminant that people are responsible for releasing into the atmosphere is carbon dioxide. The energy sector has been cited as being responsible for three fourths of the carbon dioxide emissions, one fifth of the methane emissions and a good portion of the nitrous oxide released into the earth’s atmosphere. Most of this comes from the burning of fossil fuels, although deforestation, land clearing, and other agricultural practices have all led to rises in pollution levels. Without some sort of agreement between countries, this could become the factor that tips the scales toward mankind as being the biggest cause of climate change.
Many of the statements that are for climate change being a natural event are true. Global climate change is natural, but it is due to men selfishness, and the fact that we are so inconsiderate, that it is taking place at such an alarmingly rapid

Global warming is a phenomenon which basically manifests as an increase in the earth’s temperature. With a warmer temperature base, the earth also undergoes various changes including the melting of its polar ice caps and the shifts in its weather patterns.
During the industrial revolution which began in the early part of 19th century, there had been massive burning of fossil fuels which resulted in emissions of carbon dioxide and other greenhouse gases. The developed nations of this world are the leaders in industrial revolution.
Name Instructor Class Date Global Climate Change Although the subject was not part of the recent presidential debates, global climate change is the most important issue facing the U.S. and the world. Also refereed to as “global warming” the phenomenon is already taking its toll on the planet.
This is the cycle of life rather than what alarmists purport to be the catastrophic incidence of global warming caused by human activity. On the other hand, because warming ceased at least 12 years ago, global warming alarmists are now starting to admit that the earth is presently cooling.
Significantly, climate change predictions give man knowledge of the future; and these predictions cannot compared to magic, neither are they opinions or speculations.(Ricky, 2008, 1) Climate predictions are based on investigation in the field of science i.e.
Life, as we know it on earth today, is being threatened by the phenomenon of Global Warming. The term denotes “the recent reported increase in the mean surface temperature of the earth; the increase being attributed to increased human activity and in particular to the increased concentration of greenhouse gases in the atmosphere”
The biggest contribution to the climate change arises from burning of the fossils releasing carbon IV oxide gas to the atmosphere (NAS 18). The burning of fossil fuels is not a natural phenomenon; it is a process
Climatic change has become one of the key areas and largely an issue of concern, both to the already developed and the least developed countries. Immense research and evaluative studies are being carried out in a bid to ascertain the present situation, and to greatly determine to what extent the problem is man-made (Ellie, 2014).
