...EFFECTS OF GLOBAL WARMING. Introduction In the past few decades, the earth has been increasingly warmer; weather changes have become more unpredictable. This phenomenon known as global warming, according to Maslin (2000), global warming is due to the massive increase in greenhouse gases such as carbon dioxide, which we are emitting into the atmosphere. Global warming can be natural or human induced, natural global warming occurs due to factors such as volcanic eruption, the relationship between the earth’s rotation axis position and revolution around the sun. However, global warming has increased over the last centuries at an unnatural pace, this has made specialist believe that the real cause of global warming is human induced. Activities that cause human induced global warming include, agricultural practices, burning of fossil, deforestation, industrial processes and the introduction of massive plants or animals. The effects of global warming may be physical, ecological, social or economic (Haldar, 2011). Some of the physical effects include extreme weather conditions such as rising temperatures, warmer temperature could lead to increased drought, more powerful and dangerous hurricanes and even intense rainstorms. Local climate change is another physical effect of global warming. According to (Haldar, 2001 ), there are three ways in which global warming can cause changes in regional climate, melting or forming ice, changing the hydro cycle and changing currents in the...

...Environmental Effects of Global Warming In order to talk about global warming, we must first learn what causes the greenhouse effect. A lot of the rays from the sun are absorbed by water vapor that is naturally in our atmosphere. Water vapor accounts for "80 percent of natural greenhouse warming. The remaining 20 percent is due to other gasses that are present in very small amounts1". Carbon dioxide is also a big absorber of the sun's heat rays. Global warming will not just make sea levels rise, it will also affect sea life. Corals "are intolerant of temperatures just a few degrees warmer than usual7". Small increases in the temperature can kill corals. There have been problems with corals dying in the past few years because of increased water temperatures. Other marine life may migrate northward or southward because the waters are warmer. The warm water would make them think that they were in their natural habitat, when they were actually migrating toward the poles. Food would be scarce in their new habitat. Patterns of the circulation of sea water are disturbed by global warming. Cold water moves along the sea floor towards the equator and warm water around the equator moves toward the poles across the surface of the ocean. It is known as thermohaline circulation. It is a very important process concerning ocean life. This circulation process brings oxygenated water to the sea floor. If this did not happen, "water along the sea floor would become depleted of the oxygen...

...Global warming, by definition is the increase in the earth's ocean and near surface temperatures. In the last several decades, there have been numerous debates regarding global warming. The vast majority of the scientific community now agrees that global warming is caused by the increase in greenhouse gasses in the atmosphere. What is more important, cheap energy or sustaining human life for the next 100+ years? Global warming is no longer fiction; scientific studies have proved that the earth's climate is under going a period of rapid change. The Intergovernmental Panel on Climate Change (IPCC) claims that the average global temperature has increased by 0.74°C since the mid-20th century and predicts that it will continue to rise by another 1.1°C to 6.4°C by the end of the 21st century (Lynas, 1). Our high dependence on fossil fuels as a source of energy has raised the atmospheric content of greenhouses gases to levels which are higher than almost any point in history. These gasses serve as a powerful insulator, and contain excess heat within our atmosphere. An overall warmer climate disrupts the ecosystem and causes disastrous impacts to take place. One of the most prominent dangers associated with global warming is the melting of the polar ice caps (Hansen 2). These enormous blocks of ice that serve as a habitat for many species of wildlife creatures are quickly melting into the ocean. The devastating impact this has on human life is that it sea levels are rising, and if not...

...Effects of Global Warming Name Professor Course Institution Date [Effects of global warming] The earth environment is warming up every day this is a direct result of the gasses discharged day by day some of these gasses incorporate methane, carbon dioxide, chlorofluorocarbons (CFCs) nitrous oxides and extra time this gasses are caught in the long-wave radiation from the Earth bringing on the air to warmth up. Researchers accept that more prominent measures of carbon dioxide in the environment, and more smoking temperatures on Earth, will essentially change the atmosphere over the entire planet. To understand this it will be necessary we understand what leads to global warming. An Earth-wide temperature boost is created by a sensation known as the nursery impact. A nursery (or glasshouse) is useful for developing things on the grounds that it traps warm inside and stays more sizzling than the air around it. A standout amongst the most quick and evident impacts of a worldwide temperature alteration is the increment in temperatures around the globe. The normal worldwide temperature has expanded by around 1.4 degrees Fahrenheit (0.8 degrees Celsius) in the course of recent years, as indicated by the National Oceanic and Atmospheric Administration (NOAA). Earth's environment acts like a massive nursery, however it traps warm an alternate way. Gasses high in the air, for example, carbon dioxide and methane, carry on like a monster bit of bended glass wrapped right round...

...layer is formed, there is too much heat on the planet, hence global warming. The discussion herein looks at some of the causes, challenges, impacts and possible solutions to the problem. Causes Global warming is the general increase in the temperatures in the planet due to the accumulation of greenhouse gases in the ozone layer. With ever increasing industrialization, greenhouse gases are released on a large scale manner to the atmosphere and formed a blanket like layer that prevents the sun’s rays from being reflected back into the space. Normally, when the rays hit the ground, they are supposed to be reflected back into the space. However, with the presence of a blanket-like layer, the rays are trapped and reflected back to earth leading to increase in temperatures. Impacts of global warming Global warming has brought with it numerous challenges in the lives of both humans and animals on earthy. There have been issues of climate change associated with extreme weather conditions. For example, today there are extreme rains that cause flooding and eventually cause destruction of property or even lead to loss of life. On the other hand, global warming has caused extreme droughts that may last for years. This culminates into poverty because there is lack of sufficient food for the people. Possible solutions Various strategies have been put in place to control the negative effects arising out of global warming. For example, policies have...

...and de Castro - Global W arming and Glaciers The Traprock, Vol. 3, M ay 2004, pp 16 - 19 16 Global Warming and its Effects on Glaciers Andrew Grosvenor, Will Roble and Marcus de Castro The addition of more greenhouse gasses to earth’s atmosphere has been blocking an increased amount of the heat radiated out from the earth’s surface. This in turn has lead to higher average global temperatures, or global warming. One of the main problems posed by this development is the melting of the earth’s glaciers. This is problematic because more liquid water will cause the planet’s sea levels to rise, possibly by as much as 66m if they are completely melted. Other environmental concerns related to melting include changes to mountain habitats and an accelerated water cycle. Although some modeling has shown no serious deterioration of the earth’s glaciers it is becoming increasingly evident that continued global warming would have serious repercussions on the planet’s ice. With the increasing acceptance of global warming as an important phenomenon occurring in our environment today, its effects on the natural cycles of the planet are becoming the center of research. One of the most interesting of these topics is the effect of global warming on the earth’s glaciers. It has been observed that increasing temperatures have and will continue to lead to glacial melting, and that the additional water will lead to a rise in the earth’s sea levels. The other potential effects of glacial melting...

...Global Warming and its Effects on Business: “The beginning of the Industrial Revolution brought many new, exciting inventions into our lives to simplify our lives and made them more efficient.” (Garrett, 1994, pp 234-235). Such inventions included cars, household appliances and plants that burn solid waste, fossil fuels such as oil, natural gas, and coal, and wood and wood products for fuel. Before the Industrial Revolution, human activities caused very few gases to be released into the atmosphere, but now scientists say, through the burning of fossil fuels, a large population growth and deforestation, humans are affecting the mixture of gases in the atmosphere. This mixture of gases in the atmosphere is causing the worldwide problem known as Global Warming. (Garrett, 1994). There are many links between global warming and the future of business, investments and the economy. Global Warming is very detrimental to our future, both scientifically and in the business world. The effects of global warming will have a profound impact on the way we live and therefore the way we carry out our business and investments. According to the United States Environmental Protection Agency, “the earth has a natural “greenhouse effect” which is caused by energy from the sun controlling the earth’s weather and climate, and heats the earth’s surface. In response to the sun, the earth radiates energy back into space.” (Clean Air Act. 2006. Retrieved January 3, 2007, from http://www.epa.gov/air/oaq_caa...

...WHAT IS GLOBAL WARMING? Global warming is defined as the increase of the average temperature on EARTH. As the earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent. Over the last 100 years, the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C, or 1.3 ± 0.32° Fahrenheit). Which does not seem that much? It is responsible for the conspicuous increase in storms, floods and raging forest fires we have seen in the last ten years. Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years. Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last eight years. [pic] WHAT IS THE GREENHOUSE EFFECT? Seen from space, our atmosphere is but a tiny layer of gas around a huge bulky planet. But it is the gaseous outer ring and it is misleadingly called greenhouse effect that makes life on EARTH possible-and that could destroy life as we know it. The sun is the Earth’s primary energy source, a burning star so hot that we can feel its heat from over 150 million kilometers away. Its rays enter our atmosphere and shower upon on our planet. About one third of this solar energy is reflected back into the universe by shimmering glaciers, water and other bright surfaces. Two thirds, however, are absorbed by...

...The Greenhouse Effect and Global Warming: Definition, Causes, and potential effects to humans, Plants, animal communities and natural resources. Discuss with illustrations. INTRODUCTION There's a delicate balancing act occurring every day all across the Earth, involving radiation the planet receives from space and the radiation that's reflected back out to space. Enormous amounts of radiation, primarily from the sun strikes the Earth's atmosphere in the form of visible light, ultraviolet, infrared and other types of radiation that are invisible to the human eye. About 30 percent of the radiation striking Earth's atmosphere is immediately reflected back out to space by clouds, ice, snow, sand and other reflective surfaces, according to NASA (National Aeronautics and Space Administration). The remaining 70 percent of incoming solar radiation is absorbed by the oceans, the land and the atmosphere. As they heat up, the oceans, land and atmosphere release heat in the form of infrared thermal radiation, which passes out of the atmosphere and into space. It is this equilibrium of incoming and outgoing radiation that makes the Earth habitable. Without this balance, the greenhouse effect sets in. Definition Greenhouse Effect: The warming of the atmosphere due to the increased amounts of greenhouse gases such as carbon dioxide, nitrous oxides and methane. These gases form a blanket over the Earth, trapping the energy or heat from the sun and preventing it from leaving the atmosphere...

...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...

...Global warming seems to some to be an abstract idea that is a cause for concern in the future, however the effects of it can already been seen in the life of a polar bear. In times past, the polar bear found food to be abundant, if somewhat hard to get, and they would have miles and miles of unbroken ice covered tundra in which roam. In recent years, however, that beautiful frozen oasis has been shrinking. It is time that the human race considers what global warming is doing to the polar bear, and see it as a glimpse into our own future if we do not take the necessary actions to get the present situation under control. Humanity’s contribution to global warming has had a dramatic effect on the polar bears by reducing their frozen habitat, making food sources more difficult to find, and by diminishing their population due to early death and low reproduction rates. All of these could be in our future if we do not acknowledge the plight of the polar bear....

...Greenhouse Effect and its Implication on Global Warming Greenhouse effect refers to an atmospheric process by which short wavelenghts of the visible light from the sun pass through the atmosphere where they are absorbed or trapped. However, part of light emitted from the sun in form of longwave is re-radiated from heated obects on the earth’s surface in to the atmosphere. Presence of greenhouse gases in the atmosphere does not allow the radiations to pass through. The greenhouse gas moelecules are more complex than any air molecule and their structure has high heat absorption capacity. The heat radiated back to the earth’s surface to modulate its temperature (Davis, 9). According to Parsons (23), this process is essential in order to support life. if this does not occur, the temperatues on the earth surcface would be below frezing point and plant or animal life would be supported. however, human activtities in the past centuries have increased the concentration of greenhouse gases in the atmosphere which inturn have increased the average temperature on the earth’s surface. Greenhouse gases include water vapor, caborndixoide, nitrous oxide and methane. Acording to a report released by IPCC in 2007, there was a significant increase in production of greenhouse gases between the 19th and 20th century (Davis, 11). Increase in population has led to increased transportation and manufacturing. This implies rise in the combustion of fossil fuels including oil, gas and coal...

...The Cause and Effects of Global Warming on the Polar Bear Most experts agree that global warming does exist and it is having a devastating effect on the Earth’s climate. A major concern of global warming is the melting of the polar ice caps. Research suggests that global warming is going to greatly impact the survival of the polar bear. In southern portions of their range, like Hudson Bay, Canada, there is no sea ice during the summer, and the polar bears must live on land until the Bay freezes in the fall, when they can once again hunt on the ice. While they are on land during the summer, the polar bears eat very little or sometimes nothing. In just 20 years the ice-free period in Hudson Bay has increased by an average of 20 days, thus cutting the polar bears' seal hunting season by nearly three weeks. Because the ice is freezing later in the fall, and melting earlier in the spring the bears have a much shorter timeframe in which to hunt during the critical season when seal pups are born. As a result, average bear weight has dropped by 15 percent, causing reproduction rates to decline. The Hudson Bay population is down more than 20 percent. Despite the fact that polar bears are good swimmers there has been an alarming increase of polar bears drowning. Although they are well adapted to water, and can swim hundreds of miles to reach solid land, the distance to reach that land is increasing dramatically as the Arctic ice disappears. It is believed that fewer and smaller ice floes...

...Global Warming And Its Effects On The Coastal Areas of Bangladesh [pic] [pic][pic] GLOBAL WARMING: Global Warming is the rise in the average temperature of the Earth’s atmosphere, including the surface air and oceans. In simple words global warming is when the Earth heats up. It is caused mainly due to increasing concentration of greenhouse gases in the Earth’s atmosphere. The greenhouse gases, include carbon dioxide, nitrous oxide, methane, water vapor, traps heat and light in the Earth’s atmosphere, which increases the temperature. Today global warming is considered as one of the major environmental issues, which threatens to disrupt the basic balance of the environment and cause large scale destruction. The Greenhouse Effect: [pic] There are certain gases that raise the temperature by trapping the sun’s heat and energy. The Earth’s average temperature would have been about 60Error! Hyperlink reference not valid. colder if it weren’t for these gases. These gases are referred to as “greenhouse effect” because of the way they help to keep the Earth warm. The greenhouse effect makes the Earth suitable for all living things. The Earth might have been freezing or it might also have been burning hot if the greenhouse effect did not occur. However, the presence of too many such gases can cause the Earth to get unusually warmer. The plants would not be able to take such heat and eventually they would have died. The scarcity of plants would cause animals to die...
