Humans are Responsible for Global Warming Essay -- environment, global

This essay offers a defense to the position that humans are responsible for global warming.What is atomic number 6 Dioxide?Before attempting to answer any questions based on observations about carbon dioxide, taking a moment to identify the carbon dioxide helps to ensure a unfastened chthonianstanding of the element. According to Princeton University (n.d.), carbon dioxide, carbon dioxide, is a heavy odorless colorless gasconade formed during respiration and by the decomposition of organic substances. This naturally occurring element is exists in the lands atmosphere where it circulates between water, plants, soil and animals. Current Carbon Dioxide LevelsKnowledge of carbon dioxide levels in the atmosphere helps scientists understand how the gas affects Earth, its atmosphere and any potential global warming. Carbon dioxide levels, criteriond in parts per million (ppm), defines a unit of measure as a measure of small levels of pollutants in air, water, body fluids, etc. Part s per million is the mass ratio between the pollutant component and the solution (TET, n.d.). Rising every year since 1958, the trustworthy atmospheric carbon dioxide level is 396.81 ppm according to carbon dioxidenow.org (2014). Scientists believe that they only have a short amount of time to get this and other greenhouse gases under control before the planet crosses the point of no return. With a level of 396.81 ppm of carbon dioxide in the atmosphere, one may wonder if this level is the highest level the Earth has seen in the last 450,000 years. According to the graphical record found at Planet Seeds website (2014), this is the highest levels of carbon dioxide level recorded in that time. In fact, the graph clearly shows a spike in carbon dioxide levels in the last portion of the g... ...3). Overview of greenhouse gases.
