We will be talking about parts per million (ppm). 1% = 1 x 10-2 = 10,000 ppm Pre-anthropogenic (1850 AD) concentration means CO2 levels in the atmosphere before humans started to burn coal, peat, oil, and gas in vast quantities. In 1850, the concentration of CO2 in the atmosphere was 280 ppm. CO2 is increasing in the atmosphere at the rate of approximately 2 ppm/yr due to human interaction. In 2013 AD, CO2 in the atmosphere is 396 ppm.
Individual ethics, morals, values and influences in an environment may influence what is considered an environmental risk. Environmental research in communities, organizations, interpersonal relationships and cultures and his or her relationship with factors in the environment can be complex and often misunderstood. Ambient variables such as lighting, temperature, sounds, building architects, and air quality all have a role in every community. The biggest most often talked about environmental risk is global warming: global warming occurs when carbon dioxide is released into the atmosphere from pollution such as emissions from vehicles, businesses (e.g. chemical companies), anything basically released into the atmosphere can cause effects on the environment.
i. The world’s population and energy usage have followed similar patterns of growth. Both tables show a relatively steady increase between 1850 and 1950, then over the next 50 years the Growth rates increase rapidly. Question 2 Environmental impact a) The ecological footprint is a model which is used to measure the amount of resources consumed by an individual or group of people .This calculation determines the impact a particular lifestyle has on the environment. Fossil fuels, such as coal, oil and natural gas are energy sources which contain large amounts of carbon, any process that uses fossil fuels will add carbon dioxide to the atmosphere.
The oil spills in California and Massachusetts raised serious issues warranting an environmental conference to prompt international awareness of environmental concerns. A combination of one natural disaster after another gave birth to the Environmental Protection Agency (EPA) in early 1980s. The EPA implemented measures for environmental improvements. It was also in the 1980s that the Chernobyl disaster spawned further action by world leaders to birth the Montreal Pact in 1987. This pact promised worldwide support for environmental concerns.
Sunspots and Flares Our Sun, the 5-billion-year-old star that sustains life here on Earth, powers photosynthesis in green plants and is ultimately the source of all food and fossil fuel. The connection and interaction between the Sun and Earth drive the seasons, currents in the oceans, weather and climate. With a core reaching a fiery 16 million degrees Kelvin (nearly 29 million degrees Fahrenheit), the Sun's surface temperature is so hot that no solid or liquid can exist there. As early as the fifth century B.C., the Chinese reported having observed dark spots on the sun. In 1960, Galileo Galilei of Italy, Johannes Fabricius of Holland, Christopher Scheiner of Germany, and Thomas Harriott of Englandeach independently
0 % of your total emissions $43 annual savings Replace single-pane windows with ENERGY STAR windows. 3 % of your total emissions $150 annual savings TOTALS 44% SAVINGS OF TOTAL EMISSIONS $1474 ANNUAL SAVINGS 4. How much would this amount to if every household in America (roughly 100 million) did this? 1474 × 1,000,000 = $1,474,000,000 annual savings 44% × 1,000,000 = 44000 % of total emissions savings 5. If everybody did this, what might the impact on the health of our environment be?
June Avant English 101 November 22, 2010 Global Warming Controversy Global warming is an increase in the average temperature of the earth’s atmosphere which causes climatic changes. Global warming leads to changes in rainfall patterns, sea level, negative impacts on plants, wildlife, and humans. Al Gore and Daniel Botkin both have great points about global warming. Botkin has a scientific perspective about global warming; however, Gore’s position is better. Al Gore uses facts and evidence to support his views about global warming.
Carbon dioxide is a heat trapping greenhouse gas. It gets “released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions” (Global Climate Change: Key Indicators, 2014). An increase in carbon dioxide means more heat is trapped thereby raising the Earth’s temperature. Global surface temperature needs to also be monitored. Not just one area but globally!
Even the extensive evidence that high amounts of greenhouse gases do have an impact on the rising temperature many still think all of this is part of the Earth’s natural cycle. During the last century temperatures have increased on a global scale, known as global warming. There has been a sharp rise in average temperature being 0.7°C between 1900 and 200. Scientists believe that this rise in temperature is mainly due to human factors and the increase of industrialisation and the revolution. These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases.
Global Warming Louis Clemens HUM/111 11/20/2011 Katie Newbanks Global warming has become a major concern over the last century. The world is much hotter now than the past. Many reasons are to blame for this global temperature increase such as fossil fuels releasing C02 emissions. C02 emissions are released from coal, oil, and natural gas burning. Coal, natural gas, and oil are burned for energy in many ways such as cars and power plants.
