Human contributions to the atmosphere. In a typical early morning winter scene in the northern US, this image shows snow covered homes being heated by oil or natural gas, electric lines carrying power that was probably also generated by burning fossil fuels, and the contrails of an airplane high above. Each of these processes adds carbon dioxide and many other gasses to the atmosphere; given that there are more than six billion humans on the planet, many living lifestyles like this, we are changing the atmosphere?s composition significantly.
