Global warming is an increase in the Earth's average temperature that alters the climate and disrupts the natural balance of nature. There are two types of causes for global warming: natural causes and man-made causes. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas and that causes some global warming. However, man-made causes probably do the most damage. There are many man-made causes. Pollution is one of the biggest man-made problems. Burning fossil fuels is one thing that causes pollution and results in the release of CO2, which is also a greenhouse gas. The effects of global warming, such as more extreme weather, glacier retreats, ice shelf disruptions, rise of sea levels, changes in rainfall patterns, etc. will have a huge impact on peopleÃÂs lives. Water scarcity will rise due to the disappearance of glaciers. Changing weather patterns will not only affect our lives, but the lives of all other organisms.

Human activity, such as deforestation, increased levels of greenhouse gases, and population increase, is the number one cause of global warming. We are cutting down millions of acres of forest. Trees that absorb our CO2 are being cut down, increasing the amount of CO2 in the air, which results in higher temperatures since CO2 is a greenhouse gas. Rice paddies, bacteria in bogs and fossil fuel production, all of these release methane, another greenhouse gas. Greenhouse gases cause the greenhouse effect, which results in global warming. Higher population also results in global warming. When population increases, the demand for electricity also increases and in most cases,
