'''Global warming''', scientifically speaking, is a worldwide increase in atmospheric temperature. This type of [[climate change]] is seen as a period of increases in global temperature, which is alternating with periods of [[global cooling]], and is a natural occurrence as part of an interval warming trend which has occurred multiple times throughout [[Earth|Earth's]] geological history.<ref>"After any given warming phase begins, thousands of years later the cyclical [[Milankovitch]] decrease in the sun's heat kicks in. The warming stops, reverses and an [[ice age]] ensues." [http://www.counterpunch.org/cockburn06092007.html Counterpunch], June 2007</ref>

Many political activists use the term '''"global warming"''' to refer the [[anthropogenic global warming theory]] (AGW), which asserts that human activity such as spewing "[[greenhouse gases]]" is causing more temperature increase than all natural causes combined. The AGW theory is supported by left-leaning political parties, as well as a majority of sovereign states, national agencies, and an intergovernmental panel (see [[IPCC]]). The reality is that there is no global crisis, despite dire warning by the UN's [[Intergovernmental Panel on Climate Change]] (IPCC). Predictions made by [[climate model]]s publicized by the IPCC have not come to pass, and the climate has shown a mild cooling since 1995.<ref>http://www.examiner.com/examiner/x-7715-Portland-Civil-Rights-Examiner~y2009m8d18-Carbon-Dioxide-irrelevant-in-climate-debate-says-MIT-Scientist</ref>
