Earlier temperature records show an even greater divergence from the IPCC's models. 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" /> The heat not detected in atmospheric records 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>

Earlier temperature records show an even greater divergence from the IPCC's models. An analysis of weather station data for 1943 to 2012 by U.S. climate researcher Roy Spencer showed that there was no significant warming over this period. The recent warming simply reverses a cooling trend that occurred in the 1960s and 1970s.
