Carbon is a natural element, and there is no correlation to the amount of carbon in the atmosphere having any effect upon the earth’s climate. In fact, scientists discovered carbon levels changed AFTER ice ages, and warming intervals. The Sun is our means to survive on this rock, and when certain events occur which will increase solar radiation, or the increased absorption of the same within our atmosphere due to factors wholly out of our control, OR our ability to change, we will simply need to adjust to those phenomenon, as mankind has done for eons.
