Global warming and climate change threatens the very existence of mankind; understanding the affects of each and implementing measures to save this planet are of dire urgency. Global warming has become a threat to everything and everyone on Earth. Global warming is caused by many natural and manmade processes that continue to affect our environment. The release of carbon dioxide and methane gases are the two main contributors to climate change. With the warming of the environment almost inevitable

Global warming You have probably heard about the phrase “global warming” hundreds of times. But what exactly does global warming means? Global warming is not about having a hot day or week or month in one part of the world. It has to do with the average temperature worldwide. Simply put‚ global warming is the unusual rapid increase in earth’s average temperature worldwide. The warming of the earth began in the mid 1800’s. In the beginning it was small and very slow but then in the 1980’s the

Argumentative Essay on Global Warming “Global warming is the increase in the average temperature of the Earth’s surface” (Global Warming) . It has the effect of making the Earth’s surface warmer compared as it was the previous years. Such warming effect is also referred to as the “greenhouse effect”. Accordingly‚ “the global average temperature has increased about 0.7 to 1.4 degrees F (0.4 to 0.8 degrees C) since the late 1800 ’s and many experts estimate that the average temperature will rise

Introduction A Global Warning: Global Warming | The world is warming dangerously. It depends either on the natural causes or the artificial causes like human based greenhouse gases. This affects both the vegetation and zoological environment and also the human | life. Its effects are gradually increasing every year.The purposes of our project are:·To investigate the causes and the effects of global warming and to present the results of our survey.·To attract attention on the solution proposals about

Global Warming The U.S. Environmental Protection Agency definition of global warming: “Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere‚ which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes‚ both natural and human induced. In common usage‚ “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human

There are main sources of greenhouse gas due to human activities. III. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases‚ and is re-radiated in all directions. A. The Earth receives energy from the sun in the form

OF GLOBAL WARMING Global warming is defined as an increase in the average temperature of the Earth’s atmosphere‚ especially a sustained increase great enough to cause changes in the global climate. The term global warming is synonymous with Enhanced green house effect‚ implying an increase in the amount of green house gases in the earth’s atmosphere‚ leading to entrapment of more and more solar radiations‚ and thus increasing the overall temperature of the earth.

Global Warming Global warming is one of the most serious challenges facing us today. To protect the health and economic well-being of current and future generations‚ we must reduce our emissions of heat-trapping gases by using the technology‚ know-how‚ and practical solutions already at our disposal. Tropical deforestation is the largest source of emissions for many developing countries‚ but slowing deforestation can’t solve the climate problem by itself. As forest-rich developing countries

Global warming refers to an unequivocal and continuing rise in the average temperature of Earth’s climate system.[2] Since 1971‚ 90% of the warming has occurred in the oceans.[3] Despite the oceans’ dominant role in energy storage‚ the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth’s surface.[4][5] Since the early 20th century‚ the global air and sea surface temperature has increased about 0.8 °C (1.4 °F)‚ with about two-thirds of the increase
