The humanity is currently facing one its biggest problem ever. Indeed, the Earth is warming and consequences might be devastating for the future generations. There is a general agreement among scientists that Earth's climate is being affected by industrial society. Industry affects global climate by releasing greenhouse gases (GHGs). The most significant GHG is carbon dioxide (CO2). While some GHGs occur naturally, others are released in the atmosphere by certain human activities such as the burning of fossil fuels, deforestation activities, and some agricultural practices. These activities affect climate by increasing the so-called 'greenhouse effect'. GHGs concentrate in the Earth's atmosphere and trap heat by blocking some of the long-wave energy the Earth normally radiates back to space. The potential consequences include more extreme weather, dislocation of agricultural and commercial activities, expansion of desert regions, a rise in sea levels, and damaged natural habitats and ecosystems. All of these threaten the natural resources that provide the world's inhabitants.
             The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed, the earth's atmosphere starts to warm, which leads to global warming. We must first learn what causes the greenhouse effect before we start with global warming. A lot of the rays from the sun are absorbed by water vapor that is naturally in our atmosphere. Water vapor accounts for "80 percent of natura...
