  1. Since the industrial revolution the concentration of some gases in the atmosphere, greenhouse gases, have increased dramatically. They have mainly increased because of increased use of fossil fuels and growing human population. Power stations put out the most greenhouse gases then any other type of jobs.These gases act like a blanket by trapping heat and causing global temperatures to rise. Carbon dioxide has increased by 113 parts per million. It does not sound like much but it poses significant problems. Compared to preindustrial levels it has increased by over 36%.

  2. ATMOSPHERICGASES • Methane has increased by 1045 ppb (150%) and nitrous oxide has increased by 44 ppb (16%). This gas produces a strong greenhouse affect even though there are low levels in the atmosphere. • CFC-12 has increased by 533 ppt however it is now banned because of the damage it did to the ozone layer. There was no CFC-12 in the atmosphere in preindustrial times. • Since preindustrial times the amount of Nitrous Oxide in the atmosphere has increased by over 16%. IN the 1750’s there was about 270 ppb but now there is over 310 ppb in the atmosphere. Nitrous oxide has one of the most powerful greenhouse effects along with methane.
