Climate change, or global warming, has become a more prevalent issue in our society as the years pass by. Science is making great leaps and advances towards predicting future correlations between nature and human events. Many lines of evidence have been presented to the public to prove that climate change is and has been in progress for years now. The five most prevalent of these lines of evidence are: radiative forcings, climate models, correlations, observed changes in climate systems above the norm, and unnatural changes in the earths natural variation such as rising ocean temperatures and levels.
What are radiative forcings? As stated in the IPCC report of 2013, radiative forcings (RFs) quantify the changes in energy fluxes caused by changes in these drivers (natural and anthropogenic substances and processes that alter Earth’s energy budget) for 2011 relative to 1750. Positive RF leads to surface warming and negative RF leads to surface cooling. According to the data collected from numerous sources for the IPCC, the total radiative forcing is positive, which has led to a large uptake in energy by the climate systems. The largest known contributor to the positive total radiative forcings is caused by the increase in the atmospheric concentration of CO2, since 1750.
Climate models have been there to support the claims and theories of climate change. Climate models reproduce observed continental scale surface temperature patterns and trends over many decades, as reported by the IPCC, and have improved since the assessment report #4 (AR4). These observations include those of rapid warming since the 20th century and cooling immediately following volcanic eruptions. Climate models are able to show us that al...

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.
The Greenhouse Effect occurs when all of the heat is being trapped which involves elements like CH4, N2O, O3. But , the one thing that causes global warming is CO2 ( Schlosser). The society has to remember that not only the elements cause this change , critics are causing the climate change also. For example , fire is natural and beneficial but it can also cause the weather to change because it releases carbon monoxide , and all of that goes up into the atmosphere which can cause global change. Not only does it cause warm temperatures but it also disrupts ecosystems pushing those to extinction for those who can’t adapt. There is also the Greenhouse effect temperatures. They have been rising to about 0.8 degrees celsius. According to Dr. Schlosser , in the atmosphere, it returns about 30% of the energy in approaching sunlight and takes in about 30% at the same time.

Many scientist believe that the current warming trend is significant because, much of it has been caused by human activities. Satellites orbiting the earth and other technological equipment enables scientists to see and collect various information about our planets climate. Scientists have studied this collected information and has revealed the many changes of our planet and how these changes are effecting our climate, a few of them are:
Climate change is a major issue that is only going to get worse. Climate change is a change in global or regional climate patterns. It has become more apparent since the mid to late 20th century onwards and is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Climate change has been an important issue for decades that has effects on the environment and people of the world with the end result potentially being catastrophic. Although many believe that prolific use of fossil fuels is the direct cause of climate change, there are many more underlying causes including population expansion as well as irresponsible consumption of natural resources that have
Earth’s climate is determined by the physics and chemistry of its atmosphere. Earth’s atmosphere consists of four layers; troposphere which is closest to earth, stratosphere, mesosphere, and thermosphere. Hardy says, “During the past 100 years we humans, as a result of burning coal, oil, and gas and clearing forests, have greatly changed the chemical composition of the thin atmospheric layer.” There is more carbon dioxide in the atmosphere due to burning fossil fuels. The atmosphere is made up of many gases such as nitrogen, oxygen, and argon. It also consists of trace gases such as carbon dioxide, methane, carbon monoxide, nitrogen oxides, chlorofluorocarbons and, ozone. The trace gases have the greatest effect on our climate (Hardy 5). Up to a certain level, these gases help to keep the planet warm by absorbing certain infrared wavelengths, so that there can be life on the planet. Thus, they trap heat in the troposphere and stop it from escaping to space (Hardy 7). Therefore, the greater amount of greenhouse gases, the more heat trapped in the atmosphere. Earth’s temperature is increasing due to increased levels of greenhouse gases such as carbon dioxide released into the air from burning fossil fuels. The Intergovernmental Panel on Climate Change (IPCC) 2001 report projects “global average surface temperature increases ranging from 1.4 to 5.8 degrees

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...
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.

Imagine a world under 2 feet of water and in total chaos. Then throw in almost biblical floods, Fissures in the earth that can be seen from space, and Tornadoes that could uplift even the biggest buildings. This is what Al Gore wants you to think. These statements are completely and utterly false. These accusations upon the people of the U.S. are not true and must be silenced.

Climate is usually defined as the "average weather" in a place. It includes patterns of temperature, precipitation (rain or snow), humidity, wind and seasons. Climate patterns play a fundamental role in shaping natural ecosystems, and the human economies and cultures that depend on them. But the climate we’ve come to expect is not what it used to be because the past is no longer a reliable predictor of the future. Our climate is rapidly changing with disruptive impacts, and that change is progressing faster than any seen in the last 2,000 years (ecy.wa.gov, 2017). Though the scientific evidence seems overwhelming in favor of climate change, there are those, for various reasons, who believe that climate change is a trick. This is disappointing, as the future of our planet is at stake, and the last thing we should do in this critical time is arguing whether or not our world is being destroyed. In order to enlighten those who believe climate change is not currently happening, I will present evidence that will show that climate change is real due to sea levels rising, frequent hurricanes and food and resource depletion. In turn, I will also answer the opposition.
