'''Anthropogenic global warming''' (AGW) is a theory that suggests that human activity is causing the [[Earth]] to warm. The theory posits that greenhouse gases, including carbon dioxide, methane, nitrous oxide, and water vapor, trap solar warmth on the planet. Computer models suggest that industrial and vehicular emissions could lead to catastrophic warming. [[Leftist]]s use this theory as a basis to propose cuts in energy production and consumption and to promote de-industrialization.

An average of radiosonde (weather balloon) and satellite data shows that the lower troposphere warmed by 0.44 degrees Celsius between 1979 and 2014.

There is even greater divergence from the IPCC's models if older temperature data is considered. A reanalysis of weather station data for 1943 to 2012 by U.S. climate researcher Roy Spencer shows that the climate cooled in the 1960s and 1970s. More recently, the climate has warmed, allowing average temperature to return to its earlier level. Unlike the official weather station record, Spencer's data includes only those stations that recorded temperature at a consistent time of day.<ref name="Spencer" />  

 

Radiosonde and satellite data are the most accurate sources for global temperature. To go back further, other methods must be used. A reanalysis of weather station data for 1943 to 2012 by U.S. climate researcher Roy Spencer shows that the climate cooled in the 1960s and 1970s. More recently, the climate has warmed, allowing average temperature to return to its earlier level.
