Global Warming Definition



Global warming is the continuing increase in global temperatures caused by both natural causes, such as warming during an interglacial period, and from the increased release of human-made greenhouse gases into the air which includes carbon dioxide, methane, nitrous oxides, chlorofluorocarbons (CFCs), and halocarbons (the replacements for CFCs). Those trap the sun's heat in the Earth's atmosphere. Resulting an increase in the volume of water which contributes to sea-level rise, these gases are caused, and released into the air, from burning gas, oil, coal, wood and other resources to create energy and also from industrial pollutants which then block heat in the earth's atmosphere and can’t escape. A warmer Earth may lead to changes in rainfall status, a rise in sea level, and a huge influence on plants, animals, and humans. Extreme and quick changes in climate may take place, rather than just a slow warming in the coming years if we don’t start solving the problem together.
