Effects

The amount of greenhouse gases in the earth’s atmosphere has been increasing. This is thought to be due to human activities. During the past five decades mankind has also introduced CFCs, which not only damage the ozone layer but also act as greenhouse gases. Greenhouse gases also include carbon dioxide, methane, and nitrous oxide. As the Earth warms up a number of changes in the weather will occur. A rise of a few degrees Celsius in temperature could change the conditions on Earth, which are currently just right for existing plants and animals. If the Earth continues to warm as climate models have predicted, the temperature at the Earth’s surface may be 3 °C warmer by 2100 than it is today. This rapid change in temperature would be harmful to many ecosystems, and many species of plants and animals. Climate change will affect rainfall, sea level and storm events, and humans would also be affected by these factors.
