Global Warming

To blame humans or not to blame humans for global warming, that is the question. Reports have noted that eleven out of the last twelve years have ranked among the warmest on record. CNN has stated that temperature changes have been noticed over the last 50 years, due to human activities. Yes, humans are to blame for global warming because of population growth, deforestation, and the use of non-environmentally safe products. This world wide issue must be addressed! The increase in population has had a major affect of global warming. With more population comes the use of more cars, boats, planes, and other motorized vehicles. These powered engines cause more carbon dioxide to enter the air. Many people are acknowledging that we need to make a change in our way of living, but more vehicles are releasing enormous amounts of carbon dioxide into the atmosphere. “Most global increases are rare due to increases in carbon dioxide from fossil fuels,” says CNN. Did you know that aviation causes 3.5 percent of global warming? This seems like a little amount but, if you think of all the times planes depart and land per day it really adds up. Then, when there is traffic on the ground and vehicles are at a stand-still, they can use up to six hundred million gallons of gas, while just sitting in traffic. This is common in many cities, worldwide. The amount of fossil fuels that are burned during traffic translates to 7.5 million tons of carbon dioxide. Vehicles with poor gas mileage contribute to that number even more than regular cars. Imagine that all the transportation that occurs throughout the day keeps increasing as the population increases. There will be so much emission of carbon dioxide that temperatures will increase dramatically. We need to lower the transportation rates in order for our economy to avoid suffering. So many people are in the world and the number is increasing daily; 9,538,988,263 is a large number of people with many already driving. Deforestation has had and still continues to be a driving force on global warming. Too many trees are being cut down. In the Amazon Rainforest, within twenty-six years it went from a dense thick layer of green forest, to an empty looking wasteland. When trees are cut down, the process of photosynthesis can’t take place, therefore; large amounts of carbon dioxide are left in the air, and there is less oxygen. These CO2 bonds interfere with the CO3 ones in the ozone. Global warming is greatly affected by deforestation due to the increase in green house gasses it causes. Millions of acres are being cut down each day. In fact, some of these acres happen to be the size of Italy. When the trees have fallen or have been burned, carbon dioxide enters the air. With our actions we are losing temperate forests. Temperate forest are good to keep around because the serve a major role in reducing the amount of carbon dioxide in the air. These forests absorb two billion tons of carbon dioxide on their own. Deforestation is the second major principle that causes global warming. Humans further global warming by also using non-environmentally safe products. We use things such as hairsprays and candles which are aerosols. Aerosols have been forming holes in the ozone layer for years. “We need to use more environmentally friendly technologies,” acknowledged former President Bush. For instance, a hybrid car mainly runs on sunlight, not oil. This way it is not burning fossil fuels. Aerosols that are

Global Warming Paper Cameron Conolly For years many people have believed that we are causing the Earth to warm up faster. Global Warming is the heating of the climate. Others believe it is due to natural climate processes. Either way, we know that Global Warming is a serious issue for our Earth. One of the reasons we think Global Warming is occurring is because of Orbital Variations. “Orbital Variations” is part of a theory developed by Milutin Milkankovic. An astonishing fact about Milankovic…

GLOBAL WARMING Global warming, also called climate change, has become a topic of concern over the past decade. Climate has changed drastically over the past decade, “From 2001 through Feb, 2011 the atmospheric carbon dioxide increased by 22.2% of the total increase from 1800 to 2001” (Pangburn). Although I wasn’t completely aware of global warming and it’s circumstances until recently, I can honestly say that it is a issue to be concerned about. Global Warming is an indisputable…

GLOBAL WARMING: NATURAL OR MAN-MADE There is no question that there is an increase in Earth’s temperature and we are experiencing what is referred to as global warming. The Earth has experienced this many times in history on a much larger scale, but, humans did not exist (and would not have been able to exist) at the time. The questions now are whether human actions are accelerating the process of global warming and possibly decreasing Earth’s future sustainability; and, if so, what, if anything…

What Are the Causes of Global Warming? What is global warming? According to NASA Earth Observatory, global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed…

Global Warming: Rodriguez Tony P.3 Global warming is caused primarily by carbon dioxide from burning coal, oil and gas. Certain gases that trap heat are building up in Earth's atmosphere. The primary culprit is carbon dioxide, released from burning coal, oil and natural gas in power plants, cars, factories, etc. (and to a lesser extent when forests are cleared). The second is methane, released from rice paddies, both ends of cows, rotting garbage in landfills, mining operations…

endless debate going on about global warming. Some people say that global warming is a threat to us socially, economically, politically, and immediate actions should be taken to minimize it. Whereas, other people say that global warming is beneficial and is a natural process that is required for the sustainability of life on earth. Hence, in my opinion, global warming is a potential threat that causes harm not only to humans, but also to the planet as a whole. Global warming can be defined as the increase…

Global Warming. Is it caused by us? “…Climate change is now with us. It will not go away.”(Musil, 17) Many of us have noticed that our Earth is getting warmer. We seem to ignore what is going on and just continue with our everyday life. There is evidence that our climate has been getting warmer ever year. Some scientist believe it is because of green house gases. Green house gases include the carbon dioxide from gases that our industry produces, methane gases that cows put off, and some believe…

Global Warming Introduction: Our world is forever changing. Since its formation, naturally occurring earth processes have influenced the climate causing it to either warm or cool. In the past, these natural cycles have resulted in global climates that are very different from what we are experiencing in the year 2013. Take for instance the last ice age of the Pleistocene epoch. Still at work today, these natural influences have recently been overshadowed by the human influences on climate, said…
