The term climate change is often used interchangeably with the term global warming, but according to the National Academy of Sciences, “the phrase ‘climate change’ is growing in preferred use to ‘global warming’ because it helps convey that there are [other] changes in addition to rising temperatures.”
Climate change refers to any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). Climate change may result from:
* Human activities that change the atmosphere’s composition (e.g. through burning fossil fuels) and the land surface (e.g. deforestation, reforestation, urbanization, desertification, etc.)
* 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)
Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere, which can contribute to changes in global climate patterns.
Global warming can occur from a variety of causes, both natural and human induced. In common usage, “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities.
So in other words:
Burning fossil fuels ==> Increased carbon dioxide ==> Greenhouse Effect ==> Global warming ==> Climate change.
