Carbon dioxide is relatively transparen to shortwave UV light from the sun. However, it absorb and emit longwave radiation at wavelengths typical of the earth and atmosphere. Hence, CO2 acts much like the glass on a green house. It lets in shortwave radiation from the sun that heats the ground surface, but it restrict the loss of heat by radiation from the ground surface. The problem is, the greatly increased the amount GO2, methane and nitrous oxide, mostly by human activities can also increase green house gases concentration in the atmosphere. Before the industrial revolution, there were 280 part per mill/ion of CO2 in atmosphere. Today CO2 is 380 ppm. Just to keep green houses gases at their present level will require slashing global emission by 60 %. Everyone is part of the problem. Everyone contribution is needed. Evenryone can share of small steps around the house, office and neighboorhood, because little things multiplied by the million are add up, just as surely as individual CO2 molecules are add up. A carbon footprint is a “measure of the impact human activities have on the environment in terms of the amount of green house gases produced, measured in units of carbon dioxide” It is meant to be useful for individuals and organizations to conceptualize their personal (or organizational) impact in contributing to global warming.
