New research as published by Science Daily on December 31, 2009 finds that the percentage of carbon dioxide in the atmosphere is unchanged during the past 50 years, or even during the past 150 years, since before the industrial revolution.
An excerpt from the article says that "Wolfgang Knorr of the Department of Earth Sciences at the University of Bristol reanalyzed available atmospheric carbon dioxide and emissions data since 1850 and considers the uncertainties in the data. In contradiction to some recent studies, he finds that the airborne fraction of carbon dioxide has not increased either during the past 150 years or during the most recent five decades." Knorr goes on to say that the plant life and oceans of Earth are able to obsorb CO2 emissions, which leads to a virtually unchanged percentage of carbon in our atmosphere over the last 150 years.
Since the climate models used to convince the world that "global warming" is not only real, but also human-induced assume an increase in carbon dioxide levels in the atmosphere , and it is now clear that this increase is false, it continues to become increasingly obvious that legislation like "Cap and Trade" is entirely unnecessary. It becomes further complicated by the fact that this legislation would raise energy costs, likely worsening an already fragile economy.
