Does Global Warming Exist - 1815 Words

How do we know that Climate Change exists and what causes it? Climate change as many know it, has been a big issue around the world. There are anthropogenic and natural causes which are responsible for this cause but individually they contribute a small amount but are a huge factor as a whole. One of the main problems about the climate change is global warming. What is global warming? It is the increase in the mean temperature of the Earth’s atmosphere. It is said that the temperature has been rising by 0.5 ° every year and the highest temperature recorded was 47.6 ° in Faya, Chad in 22nd June 2010. This causes the sea levels to rise due to the snow melting. It is said that the sea levels will rise by at least 25 meters by the year 2100.†¦show more content†¦That time CFC’s (from hairspray, aerosols) were used a lot which gave out this substance which created a hole in the ozone in the lower stratosphere upper troposphere and this proves that humans can change the atmosphere. Over one third of the greenhouse gasses come from the burning of fossil fuels. The following graph shows the radiative forcing in different atmospheric concentrations; CO2, CH4, N2O and SO42- and all show a general trend. At the beginning, they are levelled but however starting from the year 1900, there is a rapid increase and this is also the time when the temperatures started to increase. Meteors Little Ice Age The trend of graph is similar to a loop, at one time it is high but it gradually decreases and back again Temperatures are expected to rise (already has) Meteors also have an impact in the atmosphere because in the year 1908 a meteorite struck the Earth. It had changed the concentrations of water vapour. The warming is caused by reduced air moisture at high altitudes where clouds are made. Clouds are formed of minute ice crystals which stop some of the sun’s rays from getting to the Earth’s surface which means the Earth gets cooler. Reoccurring Cycle Graph showing the change in temperature during the years 0- 1900 Medieval Warm Period However there is proof that this period might be just a part of a reoccurring cycle because during the years 1000-1350 AD (the medieval warm period) the temperatures were warmer.

Global warming is talked about on the news, in the newspapers, in magazines, and every other kind of social media. Today’s generation heard about global warming right out of the womb all the way to present day. I personally do believe in global warming. Is that because of the fact I was brought up in the time of the world where you hear about it basically everyday, I don’t know; it’s a good possibility. During theRead MoreGlobal Warming And Its Effects On The Environment Essay1516 Words   |  7 PagesSome people say global warming is caused by human activity, others say global warming doesn’t even exist. Some people claim that the climate is changing for the worse. They believe that humans are the primary cause of these changes, especially the increase in temperature, caused by the burning of fossil fuels. They believe that the temperature changes are causing glaciers to melt. They claim that the melting of ice masses leads to a higher sea level and worsening conditions for Arctic animals, asRead MoreThe Humanoid Effect877 Words   |  4 Pagesmight be why? Hasn’t global warming always existed? Yes. It has always been a menacing epidemic but there have been obvious changes to the environment. With the drastic weather changes, it is suspected that all of the polar ice sheets should be melted by 2100. Many scientists have studied what could be the cause of this epidemic. The fact of the matter is that the scientists have established what exactly is causing it, which are high levels of carbon dioxide. Global warming is life threatening andRead MorePeople Of Earth, What Are You Waiting For?1553 Words   |  7 PagesPeople of earth, what are you waiting for? Global warming could be considered a contested topic, although I strongly agree with the facts presented by the scientific community about the ways in which humans affect the environment. Global warming will result in large scale melting of glaciers, extinction of plants and animals, and a rise in sea levels resulting in the loss of densely populated, low lying coastal areas. Additionally, tropical diseases and the frequency of severe weather will increaseRead MoreEssay on The Threat of Global Warming1667 Words   |  7 PagesThe Threat of Global Warming Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad.   Ã‚  Ã‚  Ã‚  Ã‚  By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human historyRead MoreGlobal Warming1677 Words   |  7 PagesThrough the eyes of most scientists, global warming is seen as a very serious and severe threat.

When one encounters the concept and idea of global warming, we inquire a wide range of opinions, facts, assumptions, and philosophies. As the general population of the world, the idea of our temperature of our earth may seem meaningless to some. Although, to others global warming is a growing epidemic that is defined as the possibility of our planet becoming too warm and becoming very dangerous for human existence. So whenRead MoreGlobal Warming: Fact or Fiction? Essay867 Words   |  4 Pages Many claim that global warming is obvious and that all arguments against global warming fall. The problem is that what is â€Å"obvious† often isn’t true. â€Å"A gradual increase in the overall temperature of the earths atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.† This is the Webster dictionary definition of Global Warming, which basically says that due to an overflow of harmful and hazardous chemicalsRead MoreGlobal Warming Is Man Made886 Words   |  4 PagesGlobal Warming is Man Made There has been an ongoing debate about whether global warming is man-made, natural or if it even exists at all. The answer to that debate is that global warming is man-made and a direct result of pollution. Carbon Dioxide, methane and nitrous oxide make up the biggest part of the cause of global warming, which form greenhouse gases. Greenhouse gases are trapped in the earth’s atmosphere and cause the earth to warm up. This temperature change has an effect on the earth’sRead MoreKoch s Anti Green Strategies And Global Warming1547 Words   |  7 Pagesand experiment has emerged in the scientific community concerning global warming. These discoveries have confirmed that pollution, as a consequence of humans, has resulted in the negative effects of climate change, specifically global warming. Despite this general agreement among the scientific society, two infamously wealthy brothers, known as the Koch Brothers, pursue to deny these claims by passionately funding anti global warming efforts throughout the years. One of their more considerable accomplishments
