The world as we know it is, it is changing in all aspects like rapid advancement in technology and science factors which make the world climate to change. Climate change thus means the variation of global weather conditions. Climate change is the seasonal changes for a long period of time in the world. These climate patterns play an important role in shaping natural ecosystems, and the human economies and cultures that depend on them. For example, the changes in climate can affect how people, plants and animal live, such as food production and health risks. As the earth's climate is dynamic and always changing through a natural cycle, but most recently the scientists have recorded that the earth climatic changes are rapid, unpredictable and not following the natural cycle of global climatic changes of
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors.

Climate change is an occurrence of a change from patterns in weather which also affects land surfaces and ice sheets in global or regional areas. When climate change occurs, it continues for several decades. Climate change can often occur when there has recently been a volcano, such changes in the patterns of sun radiation or internal variability.
Climate change is a growing issue with the rise in industrial, commercial, and personal usage of energy. The burning of such things such as oil, coal and natural gases create toxic pollutants called “greenhouse gases.” The largest and most prevalent of greenhouse gases is carbon dioxide. (Overview of Greenhouse Gases). The wasteful history humanity has exhibited is deadly to the progression of our Earth. There are many things humanity can do in order to delay the inevitable warming of our planet and to prevent human-generated effects. Knowledge on the subject can significantly increase the awareness and subsequently improve the outcome of a global effort put forth by society. All that needs to be done, is to recognize our impact and how we can make a difference.

For the first time in planet earth’s history, one of its inhabitants has acquired the power to change the global climate. By releasing the huge amounts of carbon stored in fossil fuels over millions of years, mankind has disrupted the natural carbon cycle. We have intensified the natural greenhouse effect and turned it into a planetary menace that is melting our ice caps. In his award-winning documentary, An Inconvenient Truth, Al Gore (2006) states, “human activities, if unchecked in the next decade, could destroy one of the earth’s principle mechanisms for cooling itself” (p.291). The world needs to address the potentially disastrous consequences of our earth’s rapidly changing climate by acknowledging the existence of global warming and understanding its impact on the present and future generations.

You hear about it from television news broadcasts. You read about it in newspapers and magazines. You talk about it with friends and co-workers. There have even been movies made about it. The “it” is global warming. “Global warming refers to the global-average temperature increase that has been observed over the last one hundred years or more” (Spencer). Some experts argue that global warming is a result of human activities, while others believe the warming and cooling of the Earth’s atmosphere is a natural cycle. Supporters of human induced global warming stress that since the Industrial Revolution we have released excessive amounts of carbon dioxide, a known “greenhouse gas,” into the atmosphere and increased the Earth’s temperature. On the other hand, some scientists declare that based on ice core samples the Earth has experienced several warming cycles for thousands of years (Barry, 2000). Despite the ongoing debate on whether “global warming” is a natural cycle or caused by human activities, there are things individuals and nations could do to protect and conserve our environment.
Delays cause major changes in the schedule set fourth for that day. Any mechanical, food, fueling, passenger departure, passenger loading, plane loading, unloading and house cleaning needs must be met within a crucial 14 minute time frame to be considered on time within FAA regulations. If these time frames are not managed properly then the airlines begin to lose profit and they also ensue heavy fines from the federal government. These two factors are the main reasons for the emphasis on time within this industry. It is amazing just how important these time frames are for both the industry, federal government and the consumer. Their ultimate goal of daily on time performance is what motivates their employees to make this well-oiled machine continue to work. There are some very well experienced men and women that help operate these three ramp towers at the
“Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it (Michio Kaku).” For years, the suspect or suspects that cause global warming have been unknown. Two of the well-assumed and controversial possible defendants are balancing on a slightly unbalanced seesaw with scientific evidence that back up or refute their degree of involvement in the crisis. There is evidence that global warming is taking a toll on the earth and will continue to further affect it significantly in the future. To begin preventing these future calamities caused by global warming, society must first assess whether mans’ actions are causing global warming or if it is a natural phenomenon.
Climate change is undoubtedly one of the most pressing threats we face today. A global issue, it is not confined to any single neighborhood of the globe; our entire planet is threatened by this menace. The overwhelming scientific consensus is that humans are causing the climate to warm by emitting immense amounts of greenhouse gases into the atmosphere. Global warming threatens to melt the ice caps, raise sea levels, and increase the potency and frequency of severe weather events. If immediate action is not taken the situation will only continue to deteriorate. We must move swiftly to curb our use of fossil fuels and transition to a green energy economy. Although this is by no means a small undertaking, it is vital that we do so to protect

Nowadays the importance of being environmentally responsible cannot longer be ignored by our society. Indeed, one of the major threats to humanity and natural systems appears to be Climate Change (Goldenberg, 2014), which, although it has long been debated whether or not there was a link between greenhouse gas emissions and CC, according to the last United Nations IPCC Assessment Report (2013), it is extremely likely that humans are responsible for the most recent climate change.
