This seems oddly specific

Willis Eschenbach spots an assertion in Science that can’t possibly be that precise:

In their June 10th edition, in their “BY THE NUMBERS” section, they quote Nature Climate Change magazine, viz:

1,211,287: Square kilometers of ice road-accessible Arctic lands that will be unreachable by 2050, a 14% decrease, according to a report online 29 May in Nature Climate Change.

In other news, there is a publication called Nature Climate Change.

Now surely, if they can call this to the square kilometer, they ought to be able to pinpoint an exact date and time: say, 1 April 2050 at 6 am GMT. Heck, Bishop Ussher was doing that much four and a half centuries ago.

Says Eschenbach:

The idea that a hyper-accurate claim like that would not only get published in a peer-reviewed journal, but would be cited by another peer-reviewed journal, reveals just how low the climate science bar is these days. Mrs. Henniger, my high school science teacher, would have laughed such a claim out of the classroom. “Significant digits!” she would thunder.

I don’t expect to be around in 2050, but I think it’s a pretty safe bet that this guesstimate is off somewhere between 0.5 and two million square kilometers.

    Well, to be fair to the authors of the actual paper, they did state that these were theoretical averages although there is an appalling lack of error bars.

    Even theoretical averages have to have the proper number of significant digits, though.
