...dioxide and how this would affect the global climate”. (1) As technology and scientific studies progressed throughout the 1900’s and into the 21st century, the effect of human civilizations on climate change was thrust into public spotlight. While fluctuations in the earth’s climate is a natural phenomenon, the vast amount of greenhouse gases expelled into the environment due to anthropogenic influence likely enhances, or acts as a catalyst, for overall climate change. Numerous studies exist that show increases in carbon dioxide levels throughout history via direct sampling as well as ice core analysis. In 1957, “Charles Keeling began measurements of atmospheric carbon dioxide from an observatory on the Mauna Loa volcano in Hawaii. He soon identified what became known as the ‘Keeling Curve’ – a graph that showed atmospheric concentrations of carbon dioxide increasing year by year.” (2) A quick view of the Keeling Curve, even by the untrained eye, shows a strong correlation between human industrialization and the sudden increase in greenhouse gases, See Figure 1. While the increases in CO2 alone does not point to human intervention, the clearly recognizable rise in human industrialization gives legitimacy to the claim of anthropogenic induced global climate change.

...However, carbon dioxide emissions are traced to be increasing with time among many nations around the world. This increase is said to be as a result of the increase in the use of fuels such as coal due to industrialization (responsible for 40% carbon dioxide emission worldwide). (Kornelis, 2012). Moreover, research shows that these carbon dioxide emissions are likely to increase in the near future with an estimated value of 10% (Kornelis, 2012). Hypothesis The rate of carbon dioxide emissions into the environment are increasing with time. It’s expected that the emissions will be high now and in the future to come. Methods For this lab, a website link (http://www.esrl.noaa.gov/gmd/obop/) to an interactive map of the world titled “GMD Observatory Operations” was provided and the following procedures followed. i. I clicked on a starred location on the map and one location opened. ii. To the right of the screen, there were pictured graphs written on ‘Examples of Data’. I clicked the one written ‘Carbon Dioxide’. iii. Once the carbon dioxide graph opened, I took note of the CO2 concentrations from previous years to present day. iv. I then repeated steps i-iii for all the other locations on the map. v. Lastly, I used the results I found to help me assess CO2 concentration trends from 1990 to...

...Developing Cafe Alfresco into a Green Restaurant A proposed study by Chrysoberyl H. Morales Masters of Science in Culinary Arts Philippine Women’s University September 2012 Chapter 1 INTRODUCTION “Green Restaurants” are restaurants that practice their food businesses operations without contributing to the harming of our environment. Basically, these restaurants must not support the use of harmful chemicals for their supplies, does not use equipment that use excessive energy, and must be waste efficient. The history of “Green Restaurants” started in New York, in the 1990’s era. When the scientific facts that indicate that the world needs new “Green” ways, some restaurateurs in New York started building their restaurants patterned with eco-friendly procedures. Some restaurants nowadays follow this trend, like Sonya’s Garden in Tagaytay and some restaurants in Manila. Global Warming changes the Earth’s chemical atmosphere. It creates a chemical imbalance that threatens the average temperature of the world. It may not sound too serious but a slight change in the temperature may create an ecosystem imbalance. A slight change in the temperature may cause rise in our sea levels because of the melting of the ice caps in Antarctica. With the progressing support to the new environmentalism and sustainability, the hospitality and tourism sector has joined the campaign. There is a trend in the Tourism industry called, Eco-Tourism which is getting economically stronger...

Abstract Global warming is one of the most potentially disastrous issues facing mankind in the early 21st century, considered to be caused by man-made greenhouse gas emissions. Approximately 30% of the man-made carbon dioxide (CO2) emissions causing global warming is created by the burning of fossil fuels to produce electricity or used as a direct energy source. The use of solar energy to pre-heat water for industrial, commercial and institutional and residential purposes can reduce electricity usage by up to 2% to 6% in southern Ontario. Adding the emissions from using natural gas directly to heat water a figure of 5% to 17% reduction in CO2 emissions can be derived by the...
