Simplistically, we breathe out carbon dioxide, which is absorbed by plants which we then eat. Since carbon dioxide is a naturally occurring greenhouse gas, people are part of the long term cycle that has historically maintained carbon dioxide levels in the range of 260 to 280 parts per million. The problem arises when we add additional carbon dioxide to the air, from sources that had been buried in the ground, or when we permamently remove trees and vegetation that absorb carbon. So, the main ways in which people affect greenhouse gas levels are by burning fossil fuels (coal, oil and gas), deforestation and manufacture of cement. This has resulted in atmospheric carbon dioxide concentrations to rise by about 35 per cent to the present level of 380 ppm.

How does atomospheric composition affect air temperature?
While the specifics of this are controversial, the generally held beliefs are that greenhouse gases cause air temperature to rise. The primary greenhouse gases in earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone. For an extreme view of how greenhouse gases can affect temperature, do some research on Venus where greenhouse gases and the proximity to the sun have turned the planet into a furnace
