Climatic changes vary regionally.
Noone can, with certainty, predict what changes are to come. It is known that greenhouse gases released from fossil fuel burning have been increasing since the start of the industrial revolution. These gases, such as carbon dioxide, methane, and nitrous oxide are known to have heat trapping qualities. So, there is a definite connection between the concentrations of these greenhouse gases and global temperature increases. In the past, natural conditions have caused global temperature and atmospheric greenhouse gas concentrations to increase.
