Human activities have neutered the chemical composition of the atmosphere through the go onup of greenhouse gases - primarily carbon dioxide, methane, and nitrous oxide. Energy from the sun drives the earths weather and climate, and heats the earths surface in turn, the earth radiates zero back into space. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse. According to youthful studies, since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have risen by about 15%. In fact the greenhouse effect is also leading to some geomorphologic changes as well, which is resulting in ch anges of landscape.
