Global Warming is a very controversial topic between many politicians, scientists, and other researchers all over the world. Is it very difficult to decide whether environmental changes are actually occurring, or if we are just going through an ironic cycle of weather patterns. The temperature of the earth as well as levels of carbon dioxide ave varied greatly on cycles for thousands of years. Although these conditions fluctuant, the GHG concentration stays fairly stable as the amount of GHG's emitted into the atmosphere seems to balance with the amount of GHG's that are absorbed back into the Earth. This is what allows humans to live in the somewhat stable climate that we know today. Although it does not seem very harsh on the surface, the plants and wildlife are unable to keep up with the swift cycles that the Earth is moving through.
