In the 1990 IPCC report, they showed that there was insufficient temperature data for analysis in much of the Arctic, most of the southern oceans, and all of the Antarctic.
In 1978, scientists agreed data south of 30S was too meager to be reliable.
A lack of data is no obstacle for Gavin however. He simply makes the data up.
But this fraud is much worse than it seems. The fastest warming places on Gavin’s imaginary Earth are the areas with little or no data.
Using fake data allows him to keep cooling the past and warming the present.
Gavin’s fake data massively skews temperature trends upwards, and then President Obama takes Gavin’s fake numbers on the road to assist in establishing his fake “climate” agreement.
