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 a fact. Humans are causing it, and it is perhaps the most serious issue that humankind is facing today. Starting from the Industrial Revolution the amount of carbon dioxide in the air is increasing constantly. Consequently, the continuous increase in earth’s temperature is a clear indicator of how carbon dioxide effects the earth. One of the major problem that global warming is causing is the melting of sea ice in the arctic. Due to the melting of the sea ice, global temperature suffers....

- Global Warming: Fact Vs. Fiction Global Warming -- the gradual increase in planet-wide temperatures -- seems to be accepted by many scientists and people now as fact. Generally, this warming is attributed to the increase of green-house gases in the Earth's upper atmosphere. However, some solar scientists are considering whether the warming exists at all. And, if it does, might it be caused, wholely or in part, by a periodic but small increase in the Sun's energy output.... [tags: Environmental Global Climate Change]

- Throughout history global warming has been on peoples minds. Global warming is “an increase in the volume of carbon dioxide in the atmosphere, contributing to a “green-house” or insulating effect that traps heat from the sun’s rays and raises the average temperature around the world” (Viotti and Kauppi p 543). Some causes of this environmental threat are: pollution of harmful gases in the atmosphere, deforestation, and technological advances. The effects to the human population, animals, and agriculture could be dangerous.... [tags: Climate Change, Argumentative Essay]

- Through the years the topic of global warming has been the center of many heated discussions topic. Whether on scientists lab tables or politicians podiums the topic, due perhaps due to the fear of public backlash, is promptly silenced. This issue will not be pushed aside it this will be heard. There are many problems that are constantly occurring that trace back to one thing, global warming. Due to the overuse of fossil fuels and other ozone destroying agents, the world will inevitably fall into a disastrous meltdown.... [tags: Climate Change, Argumentative Essay]

- Every human activity is having a particular effect on our climate. This was noted by the world in 1992 in Rio de Janeiro when it was open for signature by the United Nations Framework on Climate Change. In the Climate Change Convention, the international community agreed to prevent and combat the effects of climate change such as those in agricultural areas, melting icecaps and the increase in sea level. In 1997, governments took the next step and agreed to the Kyoto Protocol which set as its goal the reduction of greenhouse gases emitted by industrialized countries.... [tags: Global Warming Essays]

- ... 1.4 degrees Fahrenheit doesn’t seem like a big difference but picture this, an ice cube is in the freezer at 32 degrees Fahrenheit, what will it do. It will be frozen. Now raise that temperature up to 33.4 degrees Fahrenheit, what will it do. The ice cube will melt. Even though the numerical change in temperature does not seem like much, when put into perspective, the changes could be greater than we think. Ice is a key player in affecting climate and the majority of land ice is found in the poles, the Arctic and Antarctic.... [tags: Greenhouse gas, Climate change, Global warming]

- Eric Fisher Dianna Trang AP English III 7 April 2015 Climate Change One of the most important issues lying in our world today and in the future is climate change. Whether you’re a denier or an acceptor, several scientific studies have found that a storm is coming for us in the future, so to speak. We often ask ourselves, what are these effects we hear of. This leads us to the purpose of this paper, to show that climate change will have drastic effects across the globe. As time progresses, these effects that are constantly spoken of on national news as well as through documentaries have grown to become reality....

- The Earth is being poisoned. It is a well-known fact; however, a remedy has not yet been offered. Everyday, alarming amounts of toxins are released into the atmosphere, and more recently into the Gulf of Mexico. British Petroleum (BP)--one of the largest suppliers of oil in the world--has dispersed an insurmountable amount of oil into the gulf. As a result of this, marine and bird life in the area has been severely affected. Fishermen, whose livelihoods depend on the fishing season, are being told they cannot fish....

- The believed outcome of Global Climate Change(GCC) by many people is not a good one. However it will not be as bad as 40 foot swell in the sea level, huge thunder storms, or satanic hurricanes. Yes, the world is changing, and changing in ways that we have yet to fully understand. Many people do believe that the current trend of our planet's climate will inevitably end in the destruction of the earth as we know it and out of those people most believe it is entirely humans’ fault. The human not the main cause of global climate change or reason for long term GCC.... [tags: Global Warming Essays]

- Global Climate Change Climate change is not a new concept; in fact there is evidence of major climate changes throughout the earth's history. However since the industrial revolution and especially since world war two, there has been an unprecedented change in the earth's atmosphere (Gates 4). As of March 1999, scientists reported the construction of a thousand-year record of the average temperature on earth. The results of their study concluded that a nine hundred-year cooling trend has been decisively reversed within the last fifty years (Bell and Strieber 9-10).... [tags: Global Warming Essays]
