Not just any old data set

Have been exploring the present fuss about the Yamal data which is used to show the extreme nature of present global warming.

It would seem that the Yamal data is debunked. That is, the reports of warming in the twentieth century have been greatly exaggerated.

A nice readable summary is here. A criticism is here, although it's not very good.

I think the controversy shows up how essential it is that, for proper science to be done, full data has to be shared openly. That it has taken around a decade for the information to be shared (and that it has only now happened under duress) shows that one side of the argument had something to hide.
