GLOBAL WARMING

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. Global warming cab lead too many problems that affects the environment in which we.

Existence of the greenhouse effect as such is not disputed. Naturally occurring greenhouse gases have a mean warming effect of about 33 °C (59 °F), without which Earth would be uninhabitable. On Earth, the major greenhouse gases are water vapor, which causes about 36–70% of the greenhouse effect (not including clouds); The remaining is due to other gasses that are present in other amounts are carbon dioxide (CO2), which causes 9–26%; Carbon dioxide is a big absorber of the sun's heat rays. Humans can cause a lot of carbon dioxide to be released. Every time we burn fossil fuels, we release more carbon dioxide in the atmosphere. Emissions from cars also increase the amount of carbon dioxide in the atmosphere. If there is more carbon dioxide in the air, more rays from the sun are absorbed. This will cause the atmosphere and the earth's temperature to warm. The present atmospheric concentration of CO2 is about 385 parts per million (ppm) by volume. Future CO2 levels are expected to rise due to ongoing burning of fossil fuels and land-use change. The rate of rise will depend on uncertain economic, sociological, technological, and natural developments, but may be ultimately limited by the availability of fossil fuels....
