Greenhouse gas emissions are the key factor to global warming. While greenhouse gases are fine in moderation, we are ultimately creating an excess of man-made greenhouse gases that absorb heat and radiation from the sun. Our ozone layer is trapping this heat and radiation in our atmosphere at an exponential rate.
