Using the data that was available at the time (to 2014), a final climate report from the Intergovernmental Panel on Climate Change concluded that there had been no significant increase in global surface temperature. With most temperature monitoring authorities in agreement it appeared likely that the Paris conference, scheduled for December 2015, might be postponed. Some experts, whose grants also depended on a warming trend, admitted that the period might have been even smaller than the longer-term (1951-2014) trend, but it wasn’t zero!!  But a last minute review conducted by Tom Karl, NOAA chief climatologist, found data that had not been included in previous reports and after being redeemed showed a significant warming trend of approximately 0.07 degrees Celsius providing assurance that the Paris Conference would proceed.

The above listed are anomalies representing a departure from the twentieth century average of 13.90 degrees Celsius which are used to express annual temperatures. The Slide Show link indicates the annual temperature anomaly in each report and where they were increased by an average of 0.07 degrees Celsius following a review of temperature data conducted by NOAA in late 2015, which showed no warming, just months before the Paris conference in December.

The average temperature of the earth is calculated by climate scientists by averaging adjusted temperature data for the earth’s land mass, oceans and atmosphere for the day, month and year, adding it all together and then calculating an average of the adjusted averages. The result is meaningless and is the figment of the climate scientists’ imagination. From Mitchell website.
