The rising of temperatures is caused by factors called climate forcing or “forcing mechanisms”. This includes processes such as variations in solar radiation, variations in the Earth’s orbit, mountain-building and continental drift, and changes in greenhouse gas concentration. Solar radiation gets trapped by gases, which are created on earth, in the atmosphere. The radiation comes from the sun towards earth and bounces off the earth’s surface. However much of the radiation gets trapped by the gases remaining behind which warms our planet instead of going back into space like previously. This is known as the greenhouse effect. Some of the major contributing gases are; water vapor, carbon dioxide, methane, and our ozone layer. According to sources at Real Climate, 36-85% of the greenhouse effect is due to water vapor (including clouds), followed by carbon dioxide at 9-26%, and last all the minor greenhouse gas absorbers at 7-8%. Humans contribute to the greenhouse effect by deforestation, land use changes, and burning fo...

- While the origins of our planet stretch back some 4.6 billion years, the existence of modern man can be correlated to a single minute in the entire span of our geological calendar. Mankind has progressed from the primitive innovations of building fire and wielding stone-age tools to the achievements of industrialization and globalization. In our increasing world of interconnectivity, population explosion, and technological and scientific discoveries, how do we manage the accompanying challenges that threaten our existence....

- 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”. Rather than worry too much about emissions, we should accept the world is going to get warmer anyway and adapt to global warming by building better flood defenses and developing drought resistant crops....

- Drought is a multi-causal and complex environmental issue, and can have serious socioeconomic consequences. Recently, IPCC (the Intergovernmental Panel on Climate Change) in Fourth Assessment Report (AR4) concluded that South Asia and the Middle East would experience sever, prolonged droughts as a result of global climate changes, explicitly the increase in greenhouse gases in the atmosphere (IPCC, 2007). Drought is a weather-related natural disaster whose effect is aggravated by human activities.... [tags: Environment, Climate Change]

- Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene, from approximately 110,000 to 10,000 years age (Clayton, 1997)....

- A Climate Change Analyst, also known as C.C.A., is a person that use existing climate data to create mathematical models of what will happen to ocean and land temperatures in the next 50 years. They identify the environmental impacts of existing policies. They propose policies related to alternative fuels & other factors related to climate change. They also research and evaluate climate data so they can determine how shifts in the climate affect natural resources, animals, & civilizations. They use the information to make helpful suggestions about what individuals & governments can do to ensure a higher-quality life for everyone in the face of a changing environment....

- There are growing concerns about climate change and the effect of ‘greenhouse gases’ (GHG) on the gradual increase in world temperatures over time, now commonly known as global warming. The ‘greenhouse effect’ means that ‘greenhouse gases’ such as water vapour (H2O), carbon dioxide (CO2), methane, nitrous oxide, and fluorocarbons insulate the Earth by absorbing heat from the Earth’s surface and reflecting it back into the atmosphere, acting in a similar way to a thermal blanket (Houghton, 2005)....

- Humans will not be able to survive the results of human activities due to land degradation, lack of water management skills, pollution, and increasing carbon footprints. In 1750, a revolution started globally. This revolution was called the Industrial Revolution; it changed agriculture, manufacturing, mining, transportation & technology forever. It has even changed lives economically and culturally, but most importantly, the great effects it has on the environment. “A glacier in the high Andes 5,200 meters above capital, Lima, where one of the main water supplying glaciers has shrunk by more than a kilometer over the last decade...Eskimo villagers are going hungry because global warming ha...

- Homes, towns, cities, states, nations, and countries around the world are all addressing the issue of global climate change. Individuals are beginning to realize the importance of greenhouse gas emissions and keeping our environment clean. Towns and cities are implementing new conservation programs, energy saving incentives, and many other environment-friendly initiatives. On the federal level, the U.S. government under President Bush, launched a “historic initiative [that] brings together the resources and expertise of thirteen federal agencies.” (2) The Climate Change Science Program (CCSP) is aimed at solving some of the major aspects of climate change, such as expanding the knowled...

- This essay is going to describe what the greenhouse effect is and what it does. It is also going to say what causes the greenhouse effect and the consequences of it. What is meant by the term the greenhouse effect is that the heat from the sun comes into the Earth's atmosphere and cannot get out so becomes trapped.It gets its name because this is very much like a greenhouse.This effect occurs as the incoming short wave radiation is changed when it hits the Earth's surface into long wave or infra-red radiation.Heat energy in this form is then absorbed and stored in water vapour and carbon dioxide in the atmosphere....
