Global warming is a problem that has terrible effects to the earth's environment and to the climate. Scientifically, global warming is the change of temperature in the earths near surface and occurs due to gases which are trapped in the earth's atmosphere.
Global warming has many different causes such as solar activities, volcano emissions, variations in the earth's orbit, and greenhouse effects. Greenhouse gases naturally occur in the atmosphere but some of these gases are human made and are one of the strongest effects to the environment. These human effects are from factory wastes which are thrown out in rivers, seas, or in some cases kept in a disposal area on the surface of the earth. These wastes can cause infrared radiations which warms the earth's surface and thus the atmosphere.
