Politihack did a followup :
Judith Curry, a climatologist at the Georgia Institute of Technology, also originally downplayed Heller’s claims. But after seeing the data from Texas, Curry acknowledged that he might have had a point.
“I infer from this that there seems to be a real problem with the USHCN data set, or at least with some of the stations,” Curry wrote. “Maybe it is a tempest in a teacup, but it looks like something that requires NOAA’s attention.”
That said, Curry also tweeted that “what Goddard did to the data was bogus.”
What I did to the data was exactly nothing. I left the data completely intact. That is considered bogus in climate science.
