According to the article Global Warming on NASA’s website, published by Holly Riebeek on June 3, 2010, between 1906 and 2005 the Earth’s average surface temperature rose between 1.1 to 1.6 degrees Fahrenheit. This is not the first time the Earth’s climate has changed. The climate has experienced changes since the beginning of time. Small differences that occur in the Earth’s orbit cause a somewhat different temperature. The sun is the main ingredient when it comes to temperature. In the past, the Earth’s orbit has changed, causing a slight change in temperature (Riebeek 1). This is not what the controversy sweeping the world. The problem is the more drastic change recently because of humans. The Earth has a natural heating mechanism called the Greenhouse Effect. The Greenhouse Effect is a necessary part of human existence. However, the problem is humans are increasing these greenhouse gasses by burning fossil fuels, such as oil, and burning down forests, increasing the carbon dioxide level (2). Without all this, humans would face an inevitable downfall.…
Lately, the world has been characterized by so many debates on whether global warming is real or not, debate that does not exclude even the scientists. There are several facts that scientifically prove that global warming is real. These include several human activities that lead to emission of certain gases in the air, for example fuel burning. Burning of fuels such as coal and wood emit gases such as carbon dioxide and carbon monoxide (Phil, par 2-4). These are what are called green house gases. Research shows that the amount of these gases emitted in the air is increasing in the atmosphere. These gases absorb sun’s radiation and this means that the amount or radiation in the atmosphere is increasing, resulting to the increase of atmospheric temperatures. This increase of temperatures has been associated with natural disasters such as flooding, crops failing and ice ages. Since people now know that global warming is real, they may not know all its impacts but they are sure that these impacts are going to be detrimental to the existence of human race and thus people cannot assume that it is not happening (Phil, par 2-4).…

There are also other factors causing this too; humans aren’t the only ones causing this. According to NASA, the Intergovernmental Panel on Climate Change, which is a group of 1,300 scientists from all over the world reported that there is a staggering 95 percent chance that our planet has become warmer. Mostly due to increased human activities. Since we have become so industrialized; the waste product, CO2, has increased significantly. According to NASA, CO2 levels have increased from 280 parts per million to 400 parts per million. Another contributing factor are the polar ice caps and glaciers melting; they have trapped CO2 in them, and when they melt that trapped CO2 is released out into the atmosphere too. This is a chain reaction of humans being more industrialized. Some other greenhouse gases that effect the warming of Earth include methane and nitrous oxide. Before the Earth started to go through climate change; when the Earth got hot during the day it would always cool down by night enough. But with greenhouse gases they insulate the heat and they just get trapped in the Earth’s atmosphere, and the Earth doesn’t cool down as much as it did perviously. Since the polar ice caps and glaciers are melting which is leading to sea levels rising. Since the sea levels are rising they are starting to take some of the costal areas of some countries. I’ve witnessed this myself as a kid. When I…
Two issues that worry many geologists are global warming and the greenhouse effect. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming? When humans release gases into the air, the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer, and the result is global warming. On the other hand, if there was no greenhouse effect, the earth would be too cold for humans to comfortably exist.…
Global warming is one of the most challenging environmental problems today. It comes longer and more intense heat waves. National borders have no meaning for the atmosphere. The damage of the atmosphere makes harmful elements enter and travel around the world. And now, people are worried about the global effects of air pollution. Research shows that the earth’s atmosphere is changing in ways that could be destructive to our life. Pollution could be a major cause of this.…
These activities have greatly increased atmospheric concentration of greenhouse gases, especially carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These greenhouse gases are naturally occurred and essential for life on earth as they trap the sun’s heat and keep the earth warm. If these gases were removed from the atmosphere, the earth’s temperature would plummet to -18 Celsius, far too cold to sustain our current ecosystem. However, humans are causing massive increase in these greenhouse gas emissions, enhancing their heat- trapping ability. As a result, the temperature is rising higher and higher. (Pidwimy, 2006)…
To better understand what’s happening to our planet we must first educate ourselves on what global warming is. Global warming is also known as the “Greenhouse effect”. Atmospheric gases form a shield that surrounds earth. The air that makes up our atmosphere is made of primarily of Nitrogen and Oxygen. The remainder is made up of trace gases including carbon dioxide and methane which are called greenhouse gases. As the sun’s rays strike the earth’s surface heat is radiated back into the atmosphere. Some heat escapes into space – but the remaining heat is trapped by greenhouse gases, such as methane, nitrous oxide and carbon…
When discussing global warming we need to understand what it is. Global Warming is defined as the observed century-scale rise in the average temperature of the Earth’s climate surface including the air and sea. Greenhouse gases (GHG) are released in the atmosphere, traps in heat that is meant to be exhausted and causes increased temperatures. The data on global warming and it’s immediate and long-term effects on Earth, the rate of progression and what systems are affected is still unclear. What is clear is that if significant progress is not made in the reduction of the amount of GHG’s we produce then global warming will continue to worsen until it is no longer manageable.…
1) In this article the author talks about impacts on civilizations from small and large climate changes. We have had several small climate changes in our past that affected agriculture, trade routes, and the types of products and commodities that sell. These things are occurring still to this day. But, larger climate changes have done a lot more damage in the past. They have cause the rise and fall of whole societies. For example, the Mayan Empire. It was believed to have fallen from decades of drought that ruined its agriculture base and deprived its cities of drinking water. Although, Europe’s Medieval Warm Period was the reason for the rise of Spain, France, and England, which began the expansion of farm production, population, cities, and universities.…

My awareness of the phenomenon called either "global warming" or "climate change" started immediately before the Kyoto Summit in December 1997. I read articles in the media which said that many scientists believe that the threat of global arming was alarming and that our political leaders would have to do something in order to prevent the climate from getting hotter and hotter. Since this conference climate change has fascinated me.…
What most people may not realize is that it doesn’t take much of a rise in temperature to cause catastrophic changes in the environment. Scientists have estimated that the total amount of sea ice has decreased by an alarming 30% since 1979. And the rate of melting sea ice is accelerating every year.…
“What is Global Warming?” One might ask. Well, Global Warming is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the green house. Global Warming is a silent murderer.…
