This process begins, in simple terms, with the sun’s rays hitting the earth, causing the earth’s surface to heat up. The rays are in turn reflected by the earth, only to be partially absorbed by greenhouse gases. Greenhouse gases are found in our atmosphere. They allow heat to be stored by absorbing heat rays (like in a greenhouse). This is a natural process, but one that has been thrown out of balance by anthropogenic influences. Excess greenhouse gas emissions cause more heat to be absorbed. Thus, the temperature of our atmosphere rises and the earth warms. According to the Kyoto Protocol of 1997, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), halogenated hydrofluorocarbons (HFCs), hydrofluorocarbons (HFCs) and sulfur hexafluoride (SF6) are greenhouse gases. The breakdown of greenhouse gas emissions produced in Germany in 2018 was 88.0 percent carbon dioxide, 6.1 percent methane, 4.1 percent nitrous oxide, and about 1.7 percent F-gases.
