Greenhouse gas effect comparison. Illustration comparing the natural greenhouse gas levels emitted (top of illustration in blue) compared to the human enhanced greenhouse gases emitted (lower area of illustration demonstrated in red band). With higher, human driven emission rates of greenhouse gases, more heat is trapped inside the earth's atmosphere (represented by large red arrow) leading to accelerated global-warming.
