Carbon dioxide

Since the industrial revolution, scientists have documented a trend of increasing atmospheric carbon dioxide (CO2), the main greenhouse gas. This observation has been an issue of major environmental concern in the view of the potentially devastating effects of climate change on ecosystems and human survival. Recent studies by scientists led by Wei-Jun Cai have served to underscore this fact by showing that the Arctic region and the globe are faced with a major climate challenge due to the continued

Hello, today I will present my presentation on the good and bad of carbon dioxide. This presentation will focus on the characteristics of carbon, global or local issues related to carbon dioxide, what science is doing to address these issues and the benefits and limitations of these scientific methods. The name of my element is carbon. Its symbol is the letter “C” and its atomic number is 6. Its atomic mass is 12.0107. Carbon’s abundance on the earth’s crust is 200 parts per million by weight

contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around

Carbon dioxide levels in the atmosphere are higher than they have been in the past 400 thousand years, and they are steadily rising. In part, this is due to human impact. Carbon dioxide is a natural greenhouse gas and has been a part of Earth’s atmosphere for millions of years. CO2 levels are constantly fluctuating and have a large impact on the planet including a change in climate and ocean acidification. Multiple methods are used in deciphering CO2 levels of times past. Two proxies include ice

There is much controversy concerning Carbon Dioxide emissions in recent years and the effect these emissions have on the environment. As people continue to be more interested in profits than in environmental matters conditions are likely to worsen in the near future. It is actually surprising to observe how in spite of data pointing toward the belief that CO2 emissions have a particularly negative on the environment people fail to express enough concern about this general situations. More and more

Carbon Dioxide is Killing Coral Reefs Coral reefs were among the first ecosystems recognized as being vulnerable to the increasing ocean acidification. Ocean acidification is linked to the carbon dioxide that is released to the atmosphere and the reaction with seawater. The reaction of carbon dioxide with water forms weak carbonic acid (H2C03) that leads to increased acid levels in the ocean. This process uses the chemicals that coral reefs need to build their calcium skeleton thus interfering with

"Market-based policies are a proven way to limit carbon pollution and channel capital and innovation into clean energy, helping to avert the catastrophic consequences of climate change” - EDF vice president for international climate, Nathaniel Keohan Introduction In a contemporary political setting, it is now broadly recognized that over the 20th century, the atmospheric concentrations of key greenhouse gases, particularly Carbon Dioxide have been amplified by human activity. Australia can be held

Background Information Alcohols are a class of organic compounds characterised by one or more hydroxyl (-OH) groups attached to a carbon atom of a hydrocarbon chain. They can be considered as organic derivatives of water and in which a hydrogen atom has been replaced by an alkyl group. Alcohols are a common form of organic compound and most are colourless liquids or solids at room temperature (Encyclopaedia Britannica, 2015). Combustion is the process of burning fuels or in this case alcohol.

Soil respiration is the greatest terrestrial contributor of carbon dioxide to the atmosphere and can be a direct indication of agricultural crop and soil health (Schlesinger and Andrews, 2000). The amount of carbon dioxide generated from soil respiration is influenced by several factors including, temperature, moisture, and carbon/nitrogen ratios in plant litter amongst others (Biology 208 Lab Manual 2016). The occurrence of soil respiration is as a result of root respiration which signifying healthy

every decade. Climate change is caused by increased greenhouse gases (namely Carbon Dioxide) being released into the atmosphere. Carbon Dioxide mainly comes from burning fossil fuels—coal, natural gas, and oil from power plants and oil refineries. However, a new type of technology developed from a California company named Calera is being introduced to climate-friendly energy production by reducing the amount of Carbon Dioxide output by replacing it with something more useful: cement. Turning CO2 into
