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:

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 of hunger and simultaneously resulting in the end of the human race.

Cause of Global warming:
Many things contribute to global warming. The causes can be split into two groups: 1. Natural causes. 2. Man-made or anthropogenic causes. 1. Natural causes:
Natural causes are causes created by nature. The release of methane gas from arctic tundra and wetlands is one such natural

Sea Level Rise: Impact on Bangladesh and Role of Ngos

...Bangladeshi local NGOs and their documents in related sea level rise. Sea level rise: Impacts on Bangladesh and the role of NGOs Introduction: climate change is one of the most raising issues in contemporary world. Global warming is an important cause if climate change. The temperature of the world is increasing day by day. As a result the ice of arctic areas is melting. And this is raising the sea level. Though the temperature is increasing equally all over the world but all the countries of the world are not equally affected by this global warming. Usually costal areas, islands, and lower lands are mostly affected by this sea level rise. They are flooded badly each year because of this sea level rise. Global warming not only affects the environmental life but also they affect the political economic and infrastructural basis. Bangladesh is one of the most vulnerable countries of sea level rise. As it is a costal and lower land, so here lives and properties are at a severe risk. One of the island of Bangladesh, named South Talpatti Island has already sank because of sea level rise. NGOs role is very important for Bangladesh. NGOs can play vital role in many ways. NGOs can supply knowledge and information through research which is essential for making strategy and action plan for Bangladesh Government....

A change of climate which is attributed/influenced directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate changeability observed over comparable time periods. In the latter sense it may be qualified as anthropogenic change of climate, more generally known as "global warming" or "Anthropogenic Global Warming" (AGW). 2. Presently this rapid climate change has become the major catastrophe and the greatest threat of the 21st century. No nation, however large or small, wealthy or poor, can escape the impact of climate change. Appreciating the consequences, many a times heads of frontier states, Heads of Governments, Ministers, and other heads of delegations sited together and formed various international agreements to bring down the carbon emission to a level to keep the planet liveable. But the summit concluded without expected consensus/agreement. 3. In pursuant to the present context of climate change, this paper will endeavour to highlight the various causes of world climate change, effects of it and summary of recent Copenhagen accord, analysis, criticism and cause of failure of the accord and the remedial measures to combat climate change in the suffering countries.

Bangladesh is likely to be one of the most vulnerable countries in the world to climate change. This paper discusses the possible impacts of climate change in Bangladesh through tropical cyclones, storm surges, coastal erosion and back water effect. Both qualitative and quantitative discussions are made on cyclone intensity increase for a sea surface temperature rise of 2 and 4°C. Different scenarios of storm surges under different climate change conditions are developed by using a numerical model of storm surges for the Bay of Bengal. Possible loss of land through beach erosion due to sea level rise on the eastern coast of Bangladesh is examined. Finally a few remarks are made on the adaptation options for Bangladesh in the event of climate change. Introduction Climate change is the biggest global health threat of the 21st century and is increasingly recognized as a public health priority. Bangladesh is recognized as one of the most vulnerable countries to climate change impacts in the world. It has a history of extreme climatic events claiming millions of lives...

...In the article “Global Warmings Terrible New Math” the effect of climate change and its devastating consequences on our environment were outlined. More specifically it was illustrated how developing countries are at a greater disadvantage than developed countries when it comes to adapting to climate change. This can be due to their geographical location and concepts such as space and place can explain why they’re more vulnerable. Additionally, the history of the countries development also plays a role in determining how these countries are unable to adapt to a climate crisis. Another factor that can be taken into consideration is the particular countries global processes. This brings me to my argument that developing countries struggle with adapting to...

Sea Level Rise

...as cities and counties consider its affects and implement mitigation and adaptation strategies in an attempt to limit its potential damage. Florida is particularly vulnerable to the effects of climate change. The state has over 1,200 miles of coastline, almost 4,500 square miles of estuaries and bays, more than 6,700 square miles of other coastal waters, and a low-lying topography. In addition, most of the state’s 18 million residents live within 60 miles of the Atlantic Ocean or Gulf of Mexico. Florida’s diverse and productive coastal and marine ecosystems are imperative to the state’s present and future. These ecosystems provide food and other products for its habitat as well as valuable and irreplaceable ecological functions. These systems also attract visitors from all over the world who wish to experience the beauty and recreational opportunities these locations offer. The state’s life-support system, economy, and quality of life depend on preserving and sustaining these resources over the long term . Of prime interest to Florida is the climate changes impact on rising sea levels. Sea Level Rise (SLR) has been identified as a major global problem. SLR has two causes, the melting of mountain glaciers and polar ice sheets and thermal expansion of the oceans. At present, the mean global rate of sea level rise is approximately 3 mm per year. However, within a relatively broad band of certainty, projections for future sea level rise consistently indicate a non-linear...

Convng to Nuclear Energy Sources

...There is an issue in society that continues to be a concern and needs to be seriously addressed. The problem is that global warming is increasing at a significant rate. According to NASA’s article entitled “Global Warming”, global warming is the unusual “...rapid increase in Earth’s average surface temperature,” (2014, para. 1). Our planet, Earth, has had its temperature changed a significant amount of times throughout history. These changes were due to receiving more or less sunlight from the shifts in the Earth’s orbit. However, scientists have found that over the past century another source has influenced the change of Earth’s temperature: mankind. Scientists from NASA’s Earth Observatory suggests that these significant changes are primarily due to the release of greenhouse gases as people burn fossil fuels, given the fact that the rate of temperature increase nearly doubled in the last 50 years (GlobalWarming, 2014, para. 3). Greenhouse gases allow sunlight to shine into the atmosphere freely. When the sunlight strikes the Earth’s surface, some of it reflects back to space as heat. The greenhouse gases absorbs this heat and traps it in the atmosphere keeping the Earth at a suitable temperature for humans to live in. There are various amounts of greenhouse gases but carbon dioxide, oxygen, methane and nitrous oxide seem to be more dominant (Hunt, 2011, online). However, when too much of the gas is released then too much of the heat gets trapped within the atmosphere. This...

...The effects of global warming on the environment and human life are numerous and varied. Scenarios studied by the Intergovernmental Panel on Climate Change (IPCC) predict that global warming will continue and get worse much faster than was expected even in their last report. Research by NOAA indicate that the effects of global warming are already irreversible. The IPCC reports attribute many specific natural phenomena to human causes. The expected long range effects of recent climate change may already be observed. Rising sea levels, glacier retreat, Arctic shrinkage, and altered patterns of agriculture are cited as direct consequences of human activities. Predictions for secondary and regional effects include extreme weather events, an expansion of tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact. Concerns have led to political activism advocating proposals to mitigate, or adapt to it. Geoengineering is a further potential response, which could potentially reverse some effects that may otherwise be irreversible. It is notable that many of the effects of global warming are non-linear in nature, with potential for dramatic positive feedback effects. This means that the climate may enter a critical state where small changes can trigger runaway or abrupt climate change. Geoengineering has been suggested as a means of interrupting or reversing these effects. A notable example of a 'runaway' effect is the release of methane...

Climate Change

...Climate change Global warming , the definition is the increase in the earth’s ocean and near surface temperatures. In the last decades, there have been many debates about global warming. Greenhouse gases contribute to the climate changes, greenhouses gases is carbon dioxide, but there is an ongoing debate if natural sources, such as volcanoes, and forest fires contribute to the climate changes. The United Nations Framework Convention on Climate Change (UNFCCC) created the Kyoto protocol, is an agreement among industrialized nations who have pledge to reduce their annual emission of greenhouse gasses. The kyoto protocol currently consist of over 160 nations over 55% of the worlds greenhouse gasses. The biggest contributor of the greengasses, made more than 20.6% of the world greenhouse gasses, that nation is the United States. Barack Obama , the president of U.S has created the Clean Energy Act. The CEA serve to reduce our dependence on fossil fuel. Other governments have imposed a tax on carbon emission to encourage using clean energy. Global warming is no longer fiction, scientific studies have proved that earth is undergoing a period of rapid change. The Intergovernmental Panel on Climate Change (IPCC) claims that the average global temperature has increase .74C. Our high dependence on fossil fuels as source of energy has raised the atmospheric content of greenhouses gasses levels which are higher than almost any point in history. The biggest danger with global warming is the melting...

The coast line can be defined as the line of contact between land and a body of water (Alesheikh et al., 2004). Coastal line changes are mainly due to human factors and natural factors such as waves, tides, winds, periodic storms and sea-level change. Natural factors are a result of global warming. Many scientists consider global warming force climatic change as the most serious environmental threat facing the world today. This natural factor causes erosion and accretion of the costal line.

...Global Warming: Real or Temporary Climactic Change? Global warming is “the increase in the average temperature of Earth’s near-surface air and oceans since the mid-20th century and its projected continuation” (Wikipedia, 2010). Everybody can participate and cut down on a lot of energy that we use. Some of it we cannot help, like snowstorms, wildfires and floods. Those are some of the affects we are seeing. The Earth is warming up at a rapid speed and melting the glaciers that are causing floods. Some areas are so dry that when a severe thunderstorm occurs and lighting strike, this cause a wildfire. In the news every day we are hearing about earthquakes, volcanoes and flooding. Just this past winter was the worst one we ever had. Global Warming is far from over but we can do some things to try to prevent it but God has the last say so. It was predicted long ago that mankind was going to ruin the earth with all the consumption of gas and polluting the air. If we start now trying to go green we probably can pro long the crisis. You can get tips from Al Gore the former Vice President. He has written books and has video tapes on how we can save our planet. The most talked about effort is called “going green.” Buy all natural cleaning products, use a reusable shopping bag and build energy efficient buildings.
