South Pole Warming

Eric Steig put this graph on Twitter:
The data are here. Here's a little smoother presentation of the data, in terms of anomalies relative to 1957-1986:


It's just one location -- Amundsen-Scott South Pole Station -- so it can't speak for the whole continent, and it's almost two miles in elevation, but it's still interesting.

  1. My bet is that it regresses back to the mean over the next 10 years.

  2. Any particular reason(s) why?

  3. Just a hunch. Eric Steig may have good reason to believe that something happened in the year 2000 to reverse the apparent downward trend, but I don't see it just looking at the graph. To me it just looks like fluctuations around a flat trend.

  4. Good point. The current spike is the only one in 60 years that was above a previous spike. I'll keep track and see how it looks in a year or so.
