A Direct Link Between Carbon Dioxide And Global Warming

Damon Matthews, a professor in Concordia University’s Department of Geography, found a direct connection between carbon dioxide and global warming. Matthew’s studies show that same global temperature increase, regardless of when or over what period of time the emission occurs. The effect of adding more carbon dioxide is predicted in the theory of greenhouse gases. Swedish scientist, Syante Arrhenius, first proposed the theory in 1896, based on earlier work by Fourier and Tyndall. At the same time, many scientists have reached the same conclusion. If we increase the amount of greenhouse gases in the atmosphere, the Earth’s temperature will increase. Energy is absorbed from the sun in the form of visible light and ultraviolet radiation. The earth then releases some of this energy as infrared radiation. Greenhouse gases in the atmosphere captures some of this heat, then re-emit it in all directions. During this process, carbon dioxide and other greenhouse gases keep the Earth’s surface 33 degree Celsius warmer than it would be without them. According to an ongoing temperature analysis conducted by a scientist at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8 degree Celsius. Since 1975, two-thirds of the warming has occurred at a rate of roughly 0.15-0.20 degree Celsius per decade. Our lives involve the emission of theses dangerous greenhouse gases (Bushnell 25). Carbon dioxide has increased to
