Climate change is a controversial subject that needs further investigation to conclusively prove to others that a problem exists. Even those trying to prove climate change will admit there are multiple variables that can affect the planet’s climate and many of those are not man-made.
As stated in the introduction to chapter 12, “2013: Long-term Climate Change: Projections, Com¬mitments and Irreversibility”, of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (AR5) by Collins et al. (2013), Projections of future climate change are not like weather forecasts. It is not possible to make deterministic, definitive predictions of how climate will evolve over the next century and beyond as it is with short-term weather forecasts… Projections of climate change are uncertain, first because they are dependent primarily on scenarios of future anthropogenic and natural forcings that are uncertain, second because of incomplete understanding and imprecise models of the climate system and finally because of the existence of internal climate variability. The term cli¬mate projection tacitly implies these uncertainties and dependencies.
Drawing from the research of organizations such as the IPCC and scientists skilled in multiple disciplines, I will explore the history, perceived causes and impacts of climate change. Based on this examination, I will propose my own solutions, at the local and global levels, to mitigate or adapt to probable impacts from global warming.
Background on Climate Change
History
Throughout history examples of climate change prior to the Industrial Era can be found. The Anasazi were forced to leave what is now Colorado due to severe droughts in 1130-1180 and 1275-1299. Greenland was...

Thesis Statement: Due to the limitations of global climate models used as predictors for future calamitous climate changes and the lack of fact-based knowledge regarding the climate, we should avoid geoengineering because of the unknown and possibly devastating consequences.
Climate change is on the international policy agenda primarily because of warnings from scientists. Their forecasts of a potentially dangerous increase in the average global temperature, fortuitously assisted by unusual weather events, have prompted governments to enter into perhaps the most complicated and most significant set of negotiations ever attempted. Key questions - the rapidity of global climate change, its effects on the natural systems on which humans depend, and the options available to lessen or adapt to such change - have energized the scientific and related communities in analyses that are deeply dependent on scientific evidence and research.
Global temperatures have noticeably been rising since the mid 1800’s.The average temperature has increased by 0.6 ± 0.2°C since 1860 according to (John Sweeney, 2003)with accelerated warming apparent in the latter decades of the 20th century. The legitimacy of global warming had long been debated, however in a report by (IPCC, 2007) it states that warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level. Simulations on models such as EC-Earth provide us with predictions for future climate change. Depending on levels of emissions an increase of 1 to 5.5 degrees celsius is expected in average global temperatures by 2100.
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.
How would you like to live in a home that is beginning to fall apart, but only to go on about your day and continue to neglect it until it all comes crashing down? Humans and animals share this beautiful planet that we call home. But this beautiful home of ours is being regularly and increasingly torn apart by our own ignorant actions. These actions of ours have begun to unravel the very world in which we live, causing a self-inflicted crisis known as Global Climate Change. Global Climate Change is a severe dilemma, and it is continuously becoming more evident to the world’s population that climate change is being caused by changes in the reflectivity of earth’s atmosphere and surface, the ever changing variations of energy from the sun reaching the earth, and the daunting increase in greenhouse gasses.
For years to come there will always be a speculation on whether the climate change has really taken place or not. Many believe that large companies launched this topic in order to benefit from it in profit, as there are also those who are convinced that this are consequences that have emerged from human mistakes in understanding the environment. As humans are struggling to trust one another whether it is just a big conspiracy or not or environment changing itself, we are slowly starting to feel the effects of climate change. Because of the gasses (CO2) that are in the air, atmosphere is getting warmer, thereby triggering the Greenhouse effect. Almost 70% of emitted gasses in air are CO2, which leads us to believe that this is the main cause of Global Warming. Since it is billions and billions of metric tons per year that are being released in air, many scientists conclude that temperature will most likely be more higher in twenty years from now, than it was in near past.

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 about climate change is a gross overstatement, or in some cases, a complete fabrication. Despite the evidence to the contrary, many interest groups with considerable political clout have successfully perpetuated the argument that documented changes in the environment are a product of natural cyclical changes in climate, and are not associated with human activities. However, even the acceptance of this particular brand of reality is no grounds for the disregard of environmental consciousness. Even if one accepts the premise that recent climate change is not resultant of human activity, the rationale behind environmental conservation remains ...
There is no longer any question that our world climate has changed (King, 2004). Over the last 100 years, "temperatures have risen by about 0.6 degrees Celsius and global sea level has risen by about 20cm" (K...

Solutions to Global Warming There are many solutions to reduce the amount of green house gases in the atmosphere, which causes Global Warming. A main culprit for global warming is the use of CFC's (chlorofluorocarbons). If the use of CFC's was reduced, the number of greenhouse gases will be reduced by a great deal (however there are many other thing that cause dramatic amounts of greenhouse gases including carbon dioxide and nitrous oxide). The items that contain CFC's are regular house hold items, but they can have a devastating effect on the amount of greenhouse gases in the atmosphere. They are found in aerosols, plastic foam and fridges.
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).

One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
