Singh1 To: Professor Pisano From: Navdip Singh Date: May 05‚ 2015 The Role of Individuals and Governments to understand the hazard of climate change Scientific evidence for warming of the climate system is unequivocal. Intergovernmental Panel on Climate Change Climate change‚ as defined by the United Nations Intergovernmental Panel on climate change (IPCC) “any change in climate over time‚ whether due to natural variability or as a result of human activity.” The global climate is extremely complex and has not yet to be fully

allowing it to dissipate into space. Both natural and human-made conditions can contribute to global warming‚ but human beings can do several things to reduce the effects. The biggest cause of global warming is the carbon dioxide released when fossil fuels -- such as oil and coal -- are burned for energy. So when you save energy‚ you fight global warming and save money‚ too. Here are some easy steps that you can take to help make a difference: 1. Limit Private Vehicle Driving. A very easy way to

when fossil fuels are being burnt. As a result‚ polar caps are melting and sea levels are rising. The ozone layer which protects the planet from harmful ultraviolet rays from the sun is also deteriorating as industrial chemicals are being released into the atmosphere. Consequently‚ people will be more vulnerable to skin cancer and there will be thousands of additional deaths. Air pollution is one of the main threats to the environment. Burning fossil fuels such as coal‚ gasoline‚ and fuel oil releases

energy is non-polluting‚ clean‚ reliable and renewable source of electricity. It does not pollute the air by releasing harmful gases like carbon dioxide‚ nitrogen oxide and sulphur oxide. Solar energy does not require and fuel and thus avoid the problems of transportation of fuel or the storage of radioactive waste. Hence it is very suitable for India‚ India being one of the most polluted countries of the world. Variety of uses : Solar energy can be used for variety of purposes like as heating‚ drying

these new forms of renewable energy to determine if they are a practical alternative to the use of petroleum as an energy source. If we do not try to find a clean and efficient alternative to fossil fuels‚ I am concerned for the future of our world. Background Information Petroleum oil (a type of fossil fuel) has been extracted since the early 1650’s in Europe to make kerosene for use in heat and lighting. Not until 1858 in Ontario was oil discovered by James Miller Williams to be useful as an

complicated issue facing world leaders. Warnings from the scientific community are becoming louder‚ as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests. WHAT IS GLOBAL WARMING? The global surface temperature is an estimate of the global mean surface air temperature. However‚ for changes over time‚ only anomalies... are used‚ most commonly based on the area-weighted global average

As many of us have dealt with power outages for one reason or another‚ they were usually for a very short period of time that may have seemed like forever. For the past few decades there has been a huge

cars and do most of our tasks. Fossil Fuel is a non-renewable energy source. It results from the decomposition of dead and buried organisms. They are millions of years old and are fossilized under rock and sand. They are efficient energy producers‚ however‚ they also produce carbon dioxide‚ a pollutant. Their energy is released through combustion where heat starts an exothermic reaction. The hydrogen and carbon molecules react chemically to produce heat. Fossil fuels like natural gas can be used as

solutions. The predominant factors resulting in the warming of the earth are the emissions of CO2 and deforestation. CO2‚ which damages the ozone layer‚ comes from several sources‚ but the most problematic are those coming from the burning of fossil fuels from power plants. This releases thousands of tones of CO2 into the atmosphere every year. Another cause of these emissions is the burning of gasoline for transportation‚ which continues to increase because of our demand for cars and also our

rapidly. Someday‚ it may provide a clean and abundant source of power. Solar energy is a very useful resource. Today 80% of the energy we use comes from fossil fuels and about 1% comes from solar energy. Fossil fuels are nonrenewable‚ that means that they are used up faster than they could be replaced. Also fossil fuels limited and cause pollution. Recently‚ there has been talk about creating a whole livable society in which all essential sources of man-made energy‚ which
