Notes

Coca-Cola history began in 1886 when the curiosity of an Atlanta pharmacist, Dr. John S. Pemberton, led him to create a distinctive tasting soft drink that could be sold at soda fountains. He created a flavored syrup, took it to his neighborhood pharmacy, where it was mixed with carbonated water and deemed “excellent” by those who sampled it.

Global warming is the slow increase in temperature of the earth's surface (air and oceans). Global warming has been attributed to the use of harmful chemicals, the elimination of trees, and other causes.

Global warming is the current rise in the average temperature of Earth's oceans and atmosphere and its projected continuation. An increase in global temperature will cause melting of glaciers and increase in sea level
Greenhouse gases, such as carbon dioxide, methane , water vapor, and fluorinated gases, act like a greenhouse around the earth. This means that they let the heat from the Sun into the atmosphere, but do not allow the heat to escape back into space. The more greenhouse gases there are, the larger the percentage of heat that is trapped inside the earth’s atmosphere. The earth could not exist in its present state (that is, with life) without the presence of some naturally occurring greenhouse gases, such as CO2, CH4, and water vapor. Without any greenhouse gases no heat would be trapped in atmosphere, so the earth would be extremely cold.
