Document Summary
Global warming is an aspect of climate change, referring to the long-term rise of the planet"s temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere. Greenhouse gases such as carbon dioxide, methane, carbon monoxide, chlorofluorocarbons and nitrous oxide bring about the greenhouse effect. Where these gases absorb thermal radiation, and re-radiate it back to the earth"s surface. Greenhouse gases contribute to global warming mainly from human activities such as burning fossil fuels, deforestation and farming. The burning of fossil fuels is the primary cause of current climate change, altering the earth"s ecosystems and causing human and environmental health problems. When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release carbon dioxide pollution into the atmosphere. Carbon dioxide is a greenhouse gas, greenhouse gases trap heat in our atmosphere, causing global warming. Deforestation is the largest source of carbon dioxide emissions after fossil fuel burning, causing.
