Earth's climate is mostly influenced by the first 6 miles or so of the atmosphere which contains most of the matter making up the atmosphere. This is really a very thin layer if you think about it.JWPlayer Redesign Testing
. In the book the end of nature , author Bill McKibbin tells of walking three miles to from his cabin in the Adirondack's to buy
he realized that on this short journey he
had traveled a distance equal to that of the layer of the atmosphere where almost all the action of our climate is contained.
In fact, if you were to view Earth from space, the principle part of the atmosphere would only be about as thick as the skin on an onion! Realizing this makes it more plausible to suppose that human beings can change the climate.
A look at the amount of greenhouse gases we are spewing into the atmosphere (see below), makes it even more plausible.

The most significant greenhouse gas is actually water vapor, not something produced directly by humankind in significant amounts.
However, even slight increases in atmospheric levels of carbon dioxide (CO) can cause a substantial increase in temperature.
This is another Fact
