An average of the various radiosonde (weather balloon) and satellite temperature records shows a warming trend of less that one half a degree Celsius in the lower troposphere between 1979 and 2014. This corresponds to a rate of 1.8 degrees per century. If the AGW theory was correct, the Earth would be warming at twice this rate, according to an average of 102 climate models. The various doomday forecasts prevalent in the media are based on these models, which have already proven to be inaccurate.<ref>"[https://www.newcriterion.com//cm/images/THE%20CLIMATE%20SURPRISE%20PAMPHLET.pdf The Climate Surprise Pamphet]", ''The New Criterion'', 2016.

Radiosonde and satellite data are the most accurate sources, but they do not go back far enough to establish the real temperature trend. A reanalysis of weather station data for 1943 to 2012 by U.S. climate researcher Roy Spencer shows that after a cooler period in the 1960s and 1970s, U.S. temperatures returned to their earlier level. Unlike official temperature records, Spencer's data includes only those stations that record at a consistent time of day.<ref name="Spencer" />
