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...

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”.

Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over
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.
Since 1900, analysis of a global network of tide gauge records reveals that global sea level has been rising at the rate of about 0.6 inches per decade. After 1992, satellite altimeters indicate that the rate of rise has increased to 1.2 inches per decade, which becomes the largest rate over the last 2000 years. According to NOAA scientists, continued sea level rise and land subsidence will lead to severe consequences such as massive storm surges and frequent tidal floods. Therefore, researches conducted by our group are aimed to remind people of the severity of rising sea level, raise proposals on how to slow down the pace of it, and discuss how the U.S. should prepare for the incoming profound impacts.
Our world is always changing, so is our climate. Some changes are apparent, others not so much. Climate change is an important issue of concern in the twenty-first century. Environment, if it changes at all, evolves so slowly that the difference cannot be seen in a human lifetime (Wearth, 2014). Mostly all scientists predicted that it would take thousands of years for the planet to warm up due to emissions of carbon dioxide from fossil fuels called greenhouse gases. But in the past 200 years, things began to change. The rate and the amount of warming that is happening on this planet are unprecedented. Wearth says, “People did not grasp the prodigious fact that both population and industrialization were exploding in a pattern of exponential

Scientists appear to have become aware of the issue of rising sea levels in the mid to late 1980s. An article published in Science News in 1987 predicted that “global warming… will cause… the world's oceans to expand, raising the average sea level by 4 to 8 centimeters in the next 40 years” (Monastersky). Though 4 to 8 centimeters sounds like a miniscule amount in relation to the vastness of the world’s oceans, this early article disturbed many readers. Many for this reason: early stud...

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...

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 most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
