This report shows the history of carbon dioxide use and shows graphical data of how changes in greenhouse gases have increased over the years.  The three natural greenhouse gases are carbon dioxide, nitrous oxide and methane.  The report mentions that increase of carbon dioxide is due to fossil fuel use and land use change, while increase of methane and nitrous oxide is due to agricultural use.  This aspect is then put into comparison with the changes in temperature, sea level and snow cover in the north pole.  It is believed that global warming and sea level rising will continue due to the human use of carbon dioxide.
