Introduction
In the statistical distribution of weather condition and its perfect pattern in an amount of time ranging from decades to centuries to millions of years, a substantial, long-lasting and drastic change is largely known as Climate change. It may be a change in more or fewer extreme weather events or in the distribution of weather more or less the average conditions or in average weather conditions. With the usage of theoretical models and observations methods, scientists, experts and specialists in this particular field actively works in order to perfectly understand past and future climate under certain situation and circumstances.
According to them, a climate record which is perfectly extending much deep into the Earth's past to a great extent has been properly assembled and rightly continues to be correctly built up, largely based on records of past sea levels, stable-isotope plus other analyses of sediment layers, periglacial and glacial processes, faunal and floral records, cores permanently or temporarily removed from deep accumulations of ice and geologically supportive evidence from borehole temperature related profiles. It is to be highly noted that by the instrumental record, more recent data are provided with a lot of perfection for better understanding and awareness. On the other hand, general circulation models which are perfectly based on the physical sciences are frequently used in this particular field in theoretical approaches in order to match past climate data with predictable future projections, and link effects and causes in climate change.

Conclusion
The government and citizens should largely change their particular pattern of energy production and its perfect usage to properly limit emissions of greenhouse gases plus thus the magnitude of climate changes under given situation and circumstances. Moreover, they can eagerly wait for changes to happen and largely accept the damages, losses and suffering that arise to a large extent. As much as possible, they can perfectly adapt to expected and actual changes. They can also seek the unproven ‘geoengineering’ related solutions in order to counteract certain level of the climate changes that might otherwise happen.
Climate change has become of the world’s major issue today. The earth’s climate is always changing in a very fast and also in different ways. Climate changes affect our lives psychologically, emotional and also physically. Climate change is defined as a long term change in the earth’s climate, especially a change due to the increase in the average atmospheric temperatures. Due to this change in temperature, a lot of changes has occurred in our environment, these changes include rising sea levels, flooding, melting of polar ice caps, hotter days, colder nights and heat waves. These climate changes plays an important role in shaping our natural ecosystem, our human economics and also the most important, it affects the human race. For
Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene, from approximately 110,000 to 10,000 years age (Clayton, 1997). Indeed, glaciers present sensitive indicators of climate change and global warming and by estimating and monitoring the dynamic evolution of these ice masses, several aspect of climate change impact on environmental phenomena can be revealed.
Climate change refers to shifts in the mean state of the climate or in its variability, persisting for an extended period of decades or longer (Ziervogel and Zermoglio, 2009). It is the change in average atmospheric behavior, and change in the patterns of variation around this behavior (Rumbach and Kudva, 2011). The Intergovernmental Panel on Climate Change (IPCC) declared that climate change is unequivocal as evidenced by observed changes in several global and regional climatic indicators (IPCC, 2007). At the country level, climate change refers to observable changes and permutations (undefined geographic variations) of temperature, rainfall and extreme climate events and their single or collective impacts on various agricultural production (Lasco, et al., 2009).
Climate change is a long term change in the earth’s climate. Climate change is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. There are 328,000,000 cubic miles of seawater on the planet, covering approximately 71 percent of the earth's surface. Ninety-seven percent of all water is in the oceans. The other three percent is divided amongst the two percent ice and one percent fresh water. Making earth’s waters composed mostly of salt water. Salt water covers most of our planet indicating climate change to have a giant impact on our oceans. Taking a closer look at the ocean and our water in general can reveal several clues to the greater effects of climate change and what other ways climate change can affect our planet. (2)
Over the course of recent history, much concern has been raised over the industrial revolution and the potential climate changes that it might be causing. It has been stated by global warming theorist that C02 emissions caused by human technologies are causing the world to warm, which will cause negative climate changes. The Earth may be experiencing a global warming trend and climate change; however, the process of climate change is outside of human control because human activity can barely account for any of the C02 level increases. Attempts to reduce human C02 emissions is needlessly expensive, and will have a negligible role in preventing or slowing any climatic changes such as global warming or an impending ice age. People must be prepared to adapt to the climatic changes that occur, because it is unlikely that human intervention will postpone them or limit the impact of their arrival.
Earth’s average temperature has increased about 0.8 degrees Celsius since 1880 and another degree could cause even more problems than there already are. Climate change is an important issue to be aware of because it is real and it affects you and the things around you each and every day. Every day animals lose habitats and die because climate change caused there home to burn, or their food sources started to deplete, etc. Along with these, more and more CO2 is being released into the air due to wildfires burning which is causing the atmosphere to heat even more. With the temperature increasing the oceans will become warmer and evaporation and rainfall patterns will change which will affect humans and animals, because we all work together in a system. There are many consequences of climate change like human health issues, and more animals becoming endangered, but the most important consequence is the rising amounts of wildfires.
Globally, climate change is regarded as both an urgent as well as serious issue (Stern, 2006). Defined as the lasting and significant change in the statistical distribution of the patterns of weather over periods that range between years to decades, climate change is believed to be a result of the human activities which have lead to global warming over the years (Sagan& Chyba1997). Other prospective contributors to climate change include biotic processes, solar radiation variations, volcanic eruptions and plate tectonics. Scientists continue to work actively with the aim of understanding the past as well as the future climate through observations and the use of theoretical models. A climate record has been assembled through the deep extension into the past of the earth .This assembly continues to be built up based on evidence that is geological in nature such as borehole temperature profiles, faunal and floral records, glacial process among others.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
Furthermore, this analysis must take place amidst serious gaps in the existing research and technology concerning the developing climatic conditions. For these reasons, global warming stands as one of the most daunting policy issues facing our world today. This is compounded by the debate over the very existence of climate change. While countless sources of empirical evidence testify to the very real presence of climate change the world over, considerable denial of the phenomenon still exists. The argument has been made that evidence of climate change is a gross overstatement, or in some cases, a complete fabrication.
Climate Change is any substantial change in climate that lasts for an extended period of time. One contributor to current climate change is global warming, which is an increase in Earth’s average temperature. Plants and animal species throughout the world are being affected by rising temperatures. Many plants are flowering earlier now than they once did; animals, such as the yellowbellied marmot, are emerging from hibernation earlier; and many bird and butterfly species are migrating north and breeding earlier in the spring than they did a few decades ago, all because of slight changes in temperature cues.

Climate change is an inevitable phenomenon that is being experienced globally in various forms, such as temperature rise. Sea level rise, droughts, floods, hurricanes, landslides, etc. According to the fourth assessment report of the IPCC project, even with immediate implementation of mitigation strategies, global climate change will continue for decades. Climate change is inflicting serious consequences on human wellbeing and will continue to inflict damage in the future. It is estimated that global temperature will rise by 1.8 oC - 4.0 oC by the end of the 21st century (Izaurraade, 2009).
all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that
Climate change is caused due to the release of few carbon compounds into the atmosphere, which drastically brought the weather changes all over the world. Climate change is not confined to a single region. It has become an important issue all over the world for the past few years.
According to the Canada’s Action on Climate Change, Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators. Climate change can involve both changes in average conditions and changes in variability, including, for example, extreme events. Climate change is one of the biggest crisis in the earth. It will cause a huge damage to the eco-system and human. We are the victims of the climate change. However, we are the one who cause the climate change.
Every year there are changes in climate in different parts of the world. Some of these changes are due to natural causes. However, some climatic changes are caused by air pollution and these changes may increase.
