The Earth's climate has changed many times during the planet's history, with events ranging from ice ages to long periods of warmth. Historically, natural factors such as volcanic eruptions, changes in the Earth's orbit, and the amount of energy released from the Sun have affected the Earth's climate. Beginning late in the 18th century, human activities associated with the Industrial Revolution have also changed the composition of the atmosphere and therefore, are very likely influencing the Earth's climate.
According to NOAA (National Oceanic and Atmospheric Administration) and NASA (National Aeronautics and Space Administration) data, the Earth's average surface temperature has increased by about 1.2F to 1.4F in the last 100 years. Eleven of the last twelve years rank among the 12 warmest years on record (since 1850), with the warmest two years being 1998 and 2005. Based on scientific studies conducted by the US Environmental Protection Agency, it is likely that human activit ...more

A number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accumulate in the atmosphere and trap heat that normally would exit into outer space.
By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.

It is assumed that the impact of man's industrialization using the planet's resources is the result of global warming. Scientists think it may be too late to stop global warming once the polar ice caps start to melt.
