Climate Change

Climate change refers to significant and lasting alteration of climatic patterns (e.g., temperature, precipitation, wind). It may result from: natural factors, such as changes in the sun's intensity or slow changes in the Earth's orbit around the sun; natural processes within the climate system (e.g. changes in ocean circulation); and human activities that change the atmosphere's composition (e.g., through burning fossil fuels) and the land surface (e.g., deforestation, reforestation, urbanization, desertification). During the 20th century, human activities released large amounts of carbon dioxide and other greenhouses gasses into the atmosphere, resulting in an increase in the rate of climate change.
