Greenland’s ‘Record Temperature’ denied – the data was wrong

Anthony Watts / August 12, 2019

From the “But, but, wait! Our algorithms can adjust for that!” department comes this tale of alarmist woe. Greenland’s all-time record temperature wasn’t a record at all, and it never got above freezing there.

Now from the Danish Meteorological Institute (DMI), via the news website The Local, the cooler reality:
Danish climate body wrongly reported Greenland heat record
The Danish Meteorological Institute, which has a key role in monitoring Greenland’s climate, last week reported a shocking August temperature of between 2.7C and 4.7C at the Summit weather station, which is located 3,202m above sea level at the the centre of the Greenland ice sheet, generating a spate of global headlines.  
But on Wednesday it posted a tweet saying that a closer look had shown that monitoring equipment had been giving erroneous results.  
“Was there record-level warmth on the inland ice on Friday?” it said. “No! A quality check has confirmed out suspicion that the measurement was too high.” 
…
By combining measurements with observations from other weather stations, the DMI has now estimated that the temperature was closer to -2C.
The record temperature ever recorded at Summit is 2.2C, which was reached in both 2012 and 2017. But -2C is still unusual at the station.   
Shoot out the headlines first, ask questions later.
