acid rain  One of the more destructive forms of pollution is acid rain. Acid rain occurs when fossil fuel emissions containing sulfur dioxide combine with moisture in the air to form acidic precipitation. When acid rain falls on historical monuments of limestone or marble, a chemical reaction takes place which has a corrosive effect on these structures. The reaction dissolves the material, leading to permanent damage.       Global Warming

Greenhouse   According to the National Climatic Data Center, global temperatures have risen during the past century at a rate of 0.11 degrees Fahrenheit per decade. The concern with historical monuments lies in the temperature impacts on the chemistry. Heat acts as a catalyst, speeding the rate of chemical reactions. The fate of historical monuments becomes more uncertain, and the urgency to take action increases. Global warming occurs when greenhouse gases such as carbon dioxide trap radiant heat at the earth's surface, which causes temperatures to rise.
