EAP VI/A R/W YUCHENG WAN 11/27/12 Is Global Warming Manmade? Abstract Global warming is caused by numerous activities such as driving, taking airplanes, generating electricity, displaying fireworks, using air conditioning, developing industry and logging because those activities emit so much carbon dioxide that global temperatures rise up. Trees store CO2 in the forest system, so if forests are damaged, much CO2 will be released, which will increase the global temperatures. As this paper illustrates, natural climate cycles have already changed from warm to cool, so global warming is not because of natural factors. The solutions for global warming may include improving the efficiency of energy, protecting forests, producing more energy from renewable sources, generating electricity by wind, traveling in more fuel-efficiently vehicles, riding bicycles and using more efficient electrical appliances.
The high content of carbon causes global warming and global warming causes climate change. These changes are destroying our blue planet and making the ecosystem become sicker. Unfortunately, all the high content of carbon was released by human activities. We must reduce Carbon Dioxide emissions in the next two to three years, or we will lose our natural environment that we depend upon for survival. The 11th Hour shows us the consequences of irreversible global warming that have already begun to affect our life and environment.
But what happens when the seemingly carelessness of one variant of an ecological component; humans, causes disproportion in the cycle of coexistence? The result is an ecosystem imbalance. Every year, there are millions upon millions of toxins that are released in the atmosphere and in our water sources, as a result of human activity. In addition to the naturally occurring atmospheric gases, we humans have developed products and processes that release serious pollutants into the atmosphere; these are referred to as greenhouse gases (“The Global Greenhouse Effect,” n.d.). We have created massive power plants throughout the United States that emit toxic fumes and gases.
Unfortunately, the activity of burning or combusting fossil fuels releases various kinds of hazardous substances and pollutants which eventually leads to changes in the environment; such as climate change, global warming, and changes in environmental health. Let us start with the change in climate or climate change. For over the past 150 years, the burning of fossil fuels, such as coal and oil have caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. These gases prevent heat from escaping to space, somewhat like the glass panels of a greenhouse. It would change our climate, but it would not bring us close to the level of uninhabitable Venus.
Advancing glaciers would have lowered the temperature of the shallow seas therefore such big changes in temperature would alter the amount of oxygen in the water and meant the end for any species that couldn’t adapt. Research shows that approximately 50% of all species became extinct. The Devonian period was the second mass extinction and is known as the “Age of the fish” It is famous for the thousands of species of fish that developed in the Devonian seas. During the late Devonian period, over 408-360 million years ago, ,saw mass extinction and over a fifth of marine families and more than half of marine genera gradually died out over what may have been a ten-million-year interval. Climate and sea-level changes were the causes of the extinction of many types of corals, trilobites and fish with the sponges and coral most greatly effected.
Data shows that 136 out of 700 listed cultural heritages throughout the world will be affected in the long term. If global average temperature increases by just one degree Celsius, the water will directly threaten more than 40 of sites. 5 Second, sea level rise influences indigenous communities. Climate change and sea level rise and globally, but it
Effects of Global Warming on Walruses When people talk about global warming, they think of the polar ice caps being melted and humans causing too much pollution in the air from various activities. It is actually an overall increase in the average temperature of the Earth’s surface caused by gases being trapped in the atmosphere by the “greenhouse effect” [3]. From the North down to the South Pole temperatures are rising and the world is heating up fast. This has caused many changes in the nature of things. One such victim of the change in our climate is a pinniped most commonly known as the walrus.
Since the temperatures have started to rise, the ice that they once lived on has melted and they are having a very difficult time surviving. People have increased the temperature of the Earth by contributing their pollution. Burning fossil fuels and forests has been the biggest issue amongst us all. Simple changes could help in simple ways but the fact is that since it is a global issue, the world has to be involved in order to make a difference. The United Nations has contributed in this way by holding meetings to discuss the climate changes throughout the world and what can be done to help.
Endangered Polar Bear Envision a world with an increased water and food scarcity, stronger hurricanes, melting glaciers, wildfires, rising sea levels, heat waves, and catastrophic effects on wildlife. Global warming is when the earth’s temperature heats up which is caused by greenhouse gases such as carbon dioxide, methane, and water vapor that traps heat and light from the sun in the earth’s atmosphere making it hotter than usual. The effect of the high temperatures leads to a decrease in the existence of plants, animals, and humans. Polar bears were listed as endangered species under the United States endangered species act (ESA) in May 2008. Why are polar bears endangered?
I strongly agree that people should give up their cars to save the earth. First of, according to Environmental Protection of United Kingdom, statistic proved that cars account for 22% emission of carbon dioxide which is the major contributor to climate change. World’s climate has been fluctuating throughout this decade and it arise the concern of many. Ices in North Pole are partially melted due to the drastic increase in temperature. This does not only affect the habitats living in North Pole but causing sea level to rise on top of this.
