Global temperatures are tracked by three different methods: satellites, weather balloons, and weather station data. All three methods confirm a modest amount of warming in recent decades.<ref>[http://www.euanmearns.com/wp-content/uploads/2016/01/ratpac850to300V.png Here] is a graph of the RATPAC radiosonde data. It shows 0.8 °C of warming between 1978 to 2014.</ref> Climatic change of this kind has occurred repeatedly in human history. It can be explained by the interaction of several natural cycles, including the 11-year-sunspot cycle, the Pacific decadal oscillation, and the El Nino cycle. Although the recent warming trend is much discussed in the media, it is not what the AGW theory is about. AGW posits, based on computer modelling, that a period of rapid warming is imminent.<ref>Bailey, Ronald (December 26, 2012).  [http://reason.com/blog/2012/12/26/34-years-of-satellite-temperature-data-s "34 years of satellite temperature data show global warming is on a plateau"].  Hit & Run Blog/Reason.com.  Retrieved on September 25, 2014.</ref><ref>Cole, Steve and McCarthy, Leslie (January 12, 2011).  [http://www.nasa.gov/topics/earth/features/2010-warmest-year.html "NASA research finds 2010 tied for warmest year on record"].  NASA website.  Retrieved on September 25, 2014.</ref><ref>Tisdale, Bob (August 10, 2012).  [http://wattsupwiththat.com/2012/08/10/not-hot-ocean-sst-around-the-usa-not-anywhere-near-record-levels/ "Not so hot—ocean temperatures around the USA are not anywhere near record levels"].  Watts Up with That?  Retrieved on September 25, 2014.</ref>
