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.

First, the wailing from news media:

WAPO: https://www.washingtonpost.com/news/capital-weather-gang/wp/2016/06/10/greenland-witnessed-its-highest-june-temperature-ever-recorded-on-thursday/

Now from the Danish Meteorological Institute (DMI), via the news website The Local, the cooler reality:

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.
