Highlights
Global warming is climate change that causes the average temperature of the Earth's lower atmosphere to increase. Global warming can have many different causes, but it is most commonly associated with human interference, specifically the release of excessive amounts of greenhouse gases. With this gas buildup, the Earth's atmosphere warms to unnatural temperatures, which causes, among other things, sea levels to rise. This warming trend is sometimes called the greenhouse effect because gases, such as water vapor and carbon dioxide, act like a greenhouse around the earth.
This means heat from the sun enters the atmosphere, but the heat is not allowed back into space. Global warming is...

Global warming is climate change that causes the average temperature of the Earth's lower atmosphere to increase. Global warming can have many different causes, but it is most commonly associated with human interference, specifically the release of excessive amounts of greenhouse gases. With this gas buildup, the Earth's atmosphere warms to unnatural temperatures, which causes, among other things, sea levels to rise. This warming trend is sometimes called the greenhouse effect because gases, such as water vapor and carbon dioxide, act like a greenhouse around the earth.
This means heat from the sun enters the atmosphere, but the heat is not allowed back into space. Global warming is expected to increase the intensity of forces of nature, such as tornadoes and hurricanes. Other effects of global warming include changes in agricultural yields, melting of glaciers and the extinction of certain species. Climate change also contributes to the reduction of the ozone layer. Trapping heat in the lower part of the atmosphere (global warming) leads to cooling in the upper part of the atmosphere (loss of ozone), which causes other climate changes that affect weather patterns. Ways to slow down global climate change include conservation of water, driving less, recycling and even planting a tree. Critics of global warming claim that nature, not humans, is responsible for the climate change and widespread temperature changes have been happening for years.
