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

If the AGW theory was correct, the lower troposphere would be warming at a rate of 3.1 degrees per century, according to an average of 102 climate models used by the Intergovernmental Panel on Climate Change (IPCC).<ref name="SpencerCSP2">"[https://www.newcriterion.com//cm/images/THE%20CLIMATE%20SURPRISE%20PAMPHLET.pdf The Climate Surprise Pamphlet]", ''The New Criterion'', 2016. Taken from chart "All 3 Global Temperature Dataset Types Disagree with the Climate Model During the Period of Greatest Greenhouse Concentration."</ref> Despite the numerous flaws detailed in the "Harry Read Me" file, the IPCC still favors the CRU's HadCRUT4 temperature record. This record shows warming of less than 0.6 degree from 1979 to 2014. See "[[Global warming#The temperature record|The Temperature Record]]."  The missing heat is sometimes said to be accumulating in the oceans. But a recent study by the Scripps Institution of Oceanography found that ocean temperature has risen by only 0.1 degree Celsius in the last fifty years.<ref>"[https://dailycaller.com/2018/01/05/new-study-shows-past-research-on-rising-ocean-temps-built-on-faulty-science/ New Study Shows Past Research On Rising Ocean Temps Built On Faulty Science]," ''The Daily Caller'', 01/05/2018.</ref>

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. 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" />
