Over the last few years almost everyone has heard that the earth is warming. Also, almost everyone has heard the pleas to go green and reduce carbon emissions, led by former Vice-President Al Gore. Even though there is not a truly accurate definition of global warming it can be roughly defined as a rise in average global temperature according to Laurence Pringle’s book Global Warming Assessing the Greenhouse Threat (19). Global Warming Assessing the Greenhouse Threat also bring up that the average temperature data that scientist are using only goes back to 1860 giving scientists today only 150 years of temperature data. Also, with this current warming, even with humans contributing to the rising average global temperature, scientist today do not fully understand all the complexities of the atmosphere (Pringle 19-21). According to another book by Mr. Pringle, Global Warming the Threat of Earth’s Changing Climate, scientists predict global temperatures could rise from two to six degrees Celsius by 2050 (33). Despite these predictions historical and new information show that scientist are incorrect that global temperatures will forever continue to increase. Global warming and the rise in global temperatures is due to humans burning fossil fuels and overconsumption of products, as well as natural cycles changing slightly and other natural phenomenon; however, this warming will eventually lead to global cooling.
With global temperatures predicted to rise two to six degrees Celsius by 2050, according to the book Global Warming The Threat of Earth’s changing climate, (Pringle 33) many people are becoming worried about rising sea levels from this warming (Pringle 25-26). This warming however, may have a larger side affect that many scien...

The “Go Green” lifestyle trend has emerged as a new way for humans to prevent a possible catastrophic environmental event that, some if not all, people believe will occur because of Global Warming. The people that have chosen to change their habits of recycling garbage, buying fuel efficient cars instead of 70's style gas guzzlers or live in a Eco-friendly house have spent some of their time researching what lies ahead for the human race if Global warming is not addressed. The scientific community has predicted many different environmental impact scenarios based on Global Warming, such as runaway heat waves and coastal flooding, but the one scenario that is most likely to come to pass for our planet is a new ice age. The addition of fresh water to the Atlantic Ocean caused by melting ice caps will change the current dynamics that are responsible for northern latitudes moderate climate and the added solar energy absorption in the atmosphere by greenhouse gasses will create convection currents and cool the Earth’s climate, pushing it into the next ice age.
Global warming, by definition is the “ gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.”(Webster) In the last several decades, there have been numerous debates regarding global warming. As of now it has become one of the biggest problems facing the world today. Scientists do believe that our production of greenhouse gases and carbon dioxide is having a warming effect on the atmosphere, but it also is creating a positive impact to on the planet. The controversial side is scientific consensus that it is the fault of mankind that our actions have led to the results of earthquakes, tidal waves, geographical plates moving, all because of global warming pollution. The other side that is also debated on is that global warming can bring new developments to our planet and to all that dwell within. In this paper I will examine the positive and negative side of global warming and suggest some ways nature and humans are solving the issue. Global warming is causing the largest impact to nature and humanity in the 21st century, but with green house gases on the rise, humanity, nature, and species will learn to evolve.
According to the International Panel on Climate Change (IPCC), sea levels have risen at an average rate of 1.7 ± 0.5 mm per year from the start of the 20th century.7 However, these changes have not been constant.7 From 1961 to 2003, the average rate was 1.8 ± 0.5 mm per year and from 1993 to 2003, these rates increased to 3.1 ± 0.7 mm per year.7 In the 2007 IPCC report, it was predicted that sea level rise would range from 0.18 to 0.59 meters by 2100 8, but new research indicates that ocean levels could rise by more than one meter in that time.9 These projections are approximately three times higher than those made by th...
Global Warming, much of what does or does not happen forty years from now rests on our actions or inactions taken between now and then. The crucial question is whether we should pour all our resources into mitigation – reducing our carbon emissions. According to scientists who study the climate there are other environmental problems; “we now face a global crises in land use and agriculture that could undermine the health, security, and sustainability of our civilization”.

In November of 2004, a report by 250 scientists warned that the Arctic is warming twice as fast as the global average, which threatens to wipe out several species including polar bears, and melt summer ice around the North Pole by 2100.4 One of the reasons for the increased warming is that the dark water and ground in the arctic soak up more heat from the atmosphere than ice or snow. The levels of carbon dioxide today are about 379ppm and increasing, a comparable level to 55 million years ago when there was no ice on the planet due to the warmth of the atmosphere.5 If the Greenland ice cap melts, the sea level will rise six or seven meters. Although this is a worst-case scenario, it seems clear that steps must be taken to reduce the concentration of carbon dioxide and other pollutants in our atmosphere.
The effects of global climate change on the environment are very real and already observable. In the past, some of the things scientists had predicted that global climate change would cause were loss of sea ice, accelerated sea level rise and longer, more intense heat waves. We are witnessing those changes now. According to the Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, we can expect to see a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century. The impact of these temperature rises will be beneficial in some regions and harmful in others, with the extent of climate change effects on individual regions varying over time. The IPCC predicts that net annual costs will increase over time as glo...

The world is getting hotter, and it is our fault! Global warming is the term given to the slow rise in the earth’s temperature over a long period of time, which happens when air polluting gasses like carbon dioxide and methane gases get trapped in the atmosphere making the atmosphere thick. The thick atmosphere prevents heat from escaping, which changes the earth’s temperature to a warmer climate. This warming has a negative impact on the earth and all that inhabit which makes it an environmental issue of global concern. While some may argue that global warming is not real, the earth is proving otherwise. Warmer temperatures are causing ice glaciers to melt, resulting in a rise in sea levels. Global warming is also causing a change in weather patterns, imposing devastating and unpredictable weather conditions on plants, animals, and humans. While global warming is caused partly by natural environmental occurrences out of our control, human activities are responsible the majority of global warming. The combustion of fossil fuels, chemical fertilizer use, methane emissions from factory farm animals, and deforestation are the main human activities that contribute to global warming.
According to The Fourth Assessment Report of the Intergovernmental Panel on Climate Change, “Temperature records from as far back as 1850 show that the globe has on average warmed by 0.8 degrees celsius, and further analysis has shown that since the 1970s each decade has been warmer.” (IPPC, 2007). It is expected to keep getting warmer according to IPPC and they also are estimating that the average temperature will be 2.5-4.7 degrees celsius higher in 2100. It has also been found that climate change is due to the greenhouse effect which is also produced from human activity. Greenhouse gases in the atmosphere have increased so rapidly since the Industrial Revolution that they are now changing our climate very quickly. High levels are collecting heat that is being reflected from the land and ocean and is making the air and water temperatures warmer because it is preventing it from escaping the Earth’s atmosphere. In order to keep this from happening human activities such as fossil fuel, deforestation and the conversion of land for agricultural use needs to be used
Background and Audience Relevance: There are always conversations about our planet. We see our earths glaciers melting, weather temperature rising, and pollution affecting our resources. But for some reasons we tend to look away. We should be more aware of this potential event and I’m here to inform everyone about what actually is global warming and the effects of it.
One of the major effects of global warming is the rise of sea level due to thermal expansion of the ocean, in addition to the melting of land ice. Now there are dozens of land areas that sit well below sea level and the majority of those land areas are very well populated. At least 40 percent of the world 's population lives within 62 miles of the ocean, putting millions of lives and billions of dollars ' worth of property and infrastructure at risk. (Juliet Christian-Smith, 2011) This means if the sea level rises to the projected level of 25 meters (82 feet) half of the world will retreat back to the ocean. (Rohrer, 2007) Also rising sea levels means higher tides and storm surges riding on ever-higher seas which are more dangerous to people and coastal inf...
