Local and Surrounding Ecologies and Environments of Virginia Introduction to Physical Science, SCI110 December 13, 2012 The Virginia Ecologies and Environments Ecology, as defined by Enger, Ross, & Tillery (2009), is “the branch of biology that studies the relationships between organisms and their environments”. Accordingly, the term environment is very broadly defined as “anything that affects an organism during its lifetime” (Enger, Ross, & Tillery, 2009). With these definitions

One of the primary functions of the Mauna Loa Observatory, located in Hawaii, is to measure the levels of carbon dioxide in order to determine how much of our atmosphere is comprised of this gas. A long feared benchmark among scientist has been reaching 400 parts per million as it is considered a tipping point from which our planet would be unlikely to recover from for centuries. The Earth’s atmosphere reached 400 parts per million almost 5 years ago in 2013. I specifically remember reading about

Week 5 Global Warming C02 and You Bonita Jones-Bey 1. Is your emission higher than average US emission? By how much. See report 2. What steps will you be taking to reduce your emission? We currently use one vehicle more than the other one. The one with the better ass mileage of 38 mpg. 3. What needs to be done to increase sinks and reduce sources? Change in Uses of Land Increasing carbon storage by using land differently or maintaining carbon storage by avoiding land degradation. • Encouraging

Week 13 Journal Sustainable growth, sometimes referred to as sustainability, was defined by the Brundtland Commission (World Commission on Environment and Development, 1987) as Economic Growth that “meets the needs of the present without compromising the ability of future generations to meet their own needs.” For decades, GDP and growth in GDP were widely accepted as the measure of economic and well-being. However, this growth has also been accompanied by increased damages to the socio-economic systems

Most people and institutions in the world today see climate change as the greatest threat to the environment and world stability that has ever been faced. The International Panel on Climate Change (IPCC), a UN sponsored body of over 2,000 scientists, has come to the conclusion that worldwide temperatures are likely to rise on average by 2-5 degrees Celsius in the next 100 years. They admit that it is perfectly possible that the rise could be greater than this, but even if it is contained within these

(New England Aquarium, 2013). This is the concept of global climate change. The increases in atmospheric greenhouse gases need to be mitigated. “In 2007, the IPCC published a series of scenarios ranging from “business as usual/no actions taken” to “aggressive actions taken” to reduce climate change. Models based on these scenarios from the IPCC 2007 report predict that average global surface temperatures will likely rise by an additional 2 to 11.5 degrees F (1.1 to 6.4 degrees C) above the 1980s-1990s

plays one of the important roles in people’s life. Climate is defined as the average weather, which means variety of weather conditions as rain, snow, hail, sun, and wind over period of time about 30 years that can be measured in any particular place.( IPCC Third Assessment Report - Climate Change 2001; editor:A.P.Baede) Climate change is a variation of average weather. There are 2 causes of climate change. The first is human activity which includes deforestation, burning fossil fuels, agriculture, transportation

Global warming is a very sensitive topic and one of the biggest troubles facing the world nowadays. Global warming refers to the increase in the average temperatures of the air and sea at Earth’s surface and the climate change. Over decades, scientists and researchers have made plenty of researches and decided that the temperature of the world is rising. However, this increase in temperature is mainly due to human activities on the Earth’s surface. In its recently released Fourth Assessment Report
