...what entered is reflected off of the earth’s surface in the form of UV rays and is projected back into space. A small amount of sunlight is trapped inside of the earth’s atmosphere and helps to heat the earth and keep it at a constant temperature. What is happening is that as we release more and more CO2 into the air, the earth’s atmosphere is thickening, trapping more and more UV rays, causing an increase in the atmospheric temperature. Roger Revelle, an old professor of Gore’s, was the first to suggest measuring the CO2 levels in the atmosphere. What researchers have found is that in a cyclical pattern (patterns of steadily increasing up and down movements), the atmospheric levels are on a constant increase. These patterns are cyclical in nature because in the spring, when the northern hemisphere is facing the sun (the northern hemisphere being where the largest amount of vegetation is located), the plant life absorbs the majority of the CO2 levels, reducing the levels of CO2 in the air. In the fall, when the northern hemisphere is facing away from the sun, the CO2 is released into the air, increasing the CO2 levels in the atmosphere. Evidence of an increasing atmospheric temperature is everywhere; Mount Kilimanjaro has virtually no snow covering its peaks and the polar ice caps are reducing in size at, as researchers would put it, at “extraordinary rates”. As Gore showed in his presentation, over the past 1000 years, the levels of CO2 in the atmosphere are directly correlated...

...slide show that, by his own estimate made in the film, he has given more than a thousand times. The film highlights Al Gore’s efforts to spread out the seriousness regarding Global Warming and Climate Change i.e. how we humans have brought this upon us by increasing CO2 emissions and how our situation can be improved. He first highlights the vulnerability of the Earth’s Atmospheric Shell which is being filled with pollution and is so thin that we’re capable of changing its composition. As said by him “The sun's radiation comes in the form of light waves and that heats up the Earth. And then some of the radiation that is absorbed and warms the Earth is reradiated back into space in the form of infrared radiation. And some of the outgoing infrared radiation is trapped by this layer of atmosphere and held inside the atmosphere. And that's a good thing because it keeps the temperature of the Earth within certain boundaries, keeps it relatively constant and livable. But the problem is this thin layer of atmosphere is being thickened by all of the global warming pollution that’s being put up there. And what that does is it thickens this layer of atmosphere” He explains using an animated video (on watching which even a layman would understand what global warming is) that greenhouse gases are the main cause of global warming and mocks politicians on their finding shortcuts to tackle global warming and not considering the problem seriously. Using previous years’ data on carbon...

...Introduction Global warming is a phenomenon that occurs when the earth’s atmosphere traps heat radiating from Earth toward space. Initially the sunlight transmitted was meant to pass through the atmosphere, warm the Earth’s surface, and otherwise pass freely into space. But most of the outgoing heat, however, is absorbed by the accumulated greenhouse molecules in the atmosphere and is re-emitted in all directions, ultimately leading to the warming of the planet. Over the past 50 years, the average global temperature has increased at an unsettling speed. Some human activities like mining and the burning of fossil fuels, emit CO2 and other greenhouse gases into the air. As we burn and mine more fossil fuels, greenhouse gases build up in the atmosphere...

... Group 5 Global Warming Introduction Global warming begins when sunlight reaches Earth. The clouds, atmospheric particles, reflective ground surfaces and ocean surface then reflected about 30 percent of it back into space, while the remaining is absorbed by oceans, lands and air. This in turn heats the planet’s surface and atmosphere, making life possible. As Earth warmed up, this solar energy is radiated by thermal radiation or infrared heat, travelling directly out to space, thus cooling the Earth. However, some of the outgoing radiation is re-absorbed by carbon dioxide, water vapor and other gases in the atmosphere and is radiated back to Earth’s surface; these gases are known as greenhouse gases due to their heat-trapping capacity. This re-absorption process is naturally good; the Earth’s average surface temperature would be very cold if not for the greenhouse gases. Causes of Global Warming Global Warming is caused by many things. The causes are split up into two groups, man-made or anthropogenic causes, and natural causes. Natural Causes Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years. Man-made Causes Man-made causes probably...

...has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.” (NASA.GOV) Going through the history in our planet’s timeline, global warming seems to be an issue that is rising as time moves forward. People are more focused on materialistic things and are less worried with the planet. Not thinking about the future but only about what we are living in the present, we as human beings are considered selfish. Unfortunately, the imbalance that we are creating between our lives and earth is already showing the catastrophic signs in the form of cyclones, flood, tsunami, etc. If the imbalance continues to increase, one day the conditions will put a question mark on the existence of this planet. Several current trends clearly show that global warming is directly impacting the sea levels, the melting of ice caps and significant worldwide climate changes. “When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear.” (NRDC.ORG) In short, global warming represents a fundamental threat to all living things on earth. We need to start to think not only about ourselves and take action instead of pretending...

Climate has changed when the plant received more or less sunlight due to stubble shifts in its orbit, as the atmosphere or surface changed or when the sun energy varied. However, in the past century, another force started to influence earth climate: humanity. How can we be certain that human released greenhouse gases are causing the warming? How much will the earth warm? How will the earth respond?...

...Earth is home to an abundance of astonishing, complex forms of life. We humans are constantly learning more and more about this planet. Earth has been humanity’s mysterious home since the origin of our species, but in the last century or so there has been an alarming trend taking place. We have experienced the Earth’s temperature rising. Global warming is the name of the phenomenon that has taken place over approximately the past 133 years, and according to NASA, it is an un-debated fact that the average temperature on Earth has increased one and a half degrees over this time period (NASA). There is a wide range of thoughts and opinions on the relatively recent issue of global warming. To some people, global warming is out of our hands. Therefore, it is a non-issue. Others feel that the opportunity cost of trying to prevent it is too high, especially because global warming isn’t blatantly causing any suffering on a daily basis. The perspective I have towards global warming is one that is bearing a more inconvenient, burdensome argument. This is that human activity is causing the temperatures of the Earth to rise at an unnatural pace with the widespread emission of greenhouse gases. The purpose of this argument is to raise awareness through scientific and statistical studies that humans are to blame for this trend in climate change, and that there could be significant consequences to not taking preventative measures. To absolutely prove that humans are to blame, we would need a...

...The science and technology subject that I chose to explore for this significant and ever-evolving breadth area is former Vice President Al Gore’s 2006 documentary An Inconvenient Truth: A Global Warning. Al Gore has been a long-time speaker and against global warming, and has advocated toward environmental energy efficiency and alternate fuel resources. In the years following his time in the White House, Gore focused significant time traveling throughout the world presenting the adverse effects related to global warming. This led to the creation of his documentary An Inconvenient Truth” A personal evaluation of this film considers the issue of the earth’s rising temperatures, the arguments and implications of global warming, how this topic challenged and broadened my understanding of science, and what significant elements I have taken away from viewing the film. This film is strongly connected to the Science/ Description breadth area because of its exploration of the earth’s construction and how humanity affects our planet, and many of the earth’s natural processes. According to the film, “The greatest venerable part of the Earths ecological system is the Atmosphere” (An Inconvenient Truth). One of the film’s global implications is that humans have the capability to irresponsibly damage the thin and protective layer of the Earth’s atmosphere called the Ozone. Each year, the Ozone is being thickened by pollutants causing more radiation from the sun to be trapped in the Atmosphere...

...GLOBAL WARMING: Energy, Fall 2005 v30 i4 p36(2) It could get a lot warmer. (GLOBAL WARMING) Full Text: COPYRIGHT 2005 Business Communications Company, Inc. If humans continue to use fossil fuels in a business as usual manner for the next few centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar to 14.5 degrees warmer than current day. These are the stunning results of climate and carbon cycle model simulations conducted by scientists at Lawrence Livermore National Laboratory. By using a coupled climate and carbon cycle model to look at global climate and carbon cycle changes, the scientists found that the earth would warm by 8 degrees Celsius (14.5 degrees Fahrenheit) if humans use the entire planet's available fossil fuels by the year 2300. The jump in temperature would have alarming consequences for the polar ice caps and the ocean, said lead author Govindasamy Bala of the Laboratory's Energy and Environment Directorate. In the polar regions alone, the temperature would spike more than 20 degrees Celsius, forcing the land in the region to change from ice and tundra to boreal forests. "The temperature estimate is actually conservative because the model didn't take into consideration changing land use such as deforestation and build-out of cities into outlying wilderness areas," Bala said. Today's level of atmospheric carbon dioxide is 380 parts per million (ppm). By the year 2300, the model...

...We hear the term “greenhouse gas” a lot—but what is it? Humans add various gases to the earth’s atmosphere every day; these gases (known as “greenhouse gases”) consist primarily of carbon dioxide, ozone, chlorofluorocarbons, nitrous oxide, and methane, and tend to warm the earth. Trees help counter greenhouse gas production during photosynthesis, by taking in carbon dioxide as waste material and producing oxygen, which of course we all need to survive. Scientists predict that the daily addition of greenhouse gases to the atmosphere, combined with daily removal of large portions of the world’s forests, will raise the earth’s average temperature by several degrees in the next century. This in turn will raise the level of the sea and potentially create significant changes in weather patterns on a global scale. As we move into the future, many climatologists expect that most of the United States will warm. What we do not know yet is how to scientifically predict which parts of the nation will become wetter or drier. We do know there is likely to be an overall trend toward increased precipitation and evaporation, and more intense weather systems, in the form of violent rainstorms, blizzards and sun-baked, drier soils. The Facts—What Do We Already Know About Changing Global Conditions (Global Warming)? Global temperatures are rising. Observations collected over the last century suggest that the average land surface temperature has risen 0.45-0.6°C (0.8-1.0°F) in the last...

The second part discusses the Global commons, their interactions and the effects experienced as a result of depletion of one or more of them. In this essay, “Global commons" refers to something shared in common by a community. Commons presupposes a community - its members can claim equal rights to the common ground. A global commons presupposes a global community. This essay will delve on bringing a clear understanding on the complex and highly interactive processes involving the atmosphere, land, the hydrosphere (water in oceans, seas, lakes, rivers, etc.) and the cryosphere (ice sheets, glaciers, snow), together with complex terrestrial and aquatic biological processes.
