(Twitter) – Heat wave in Antarctica, +38 °C (+68 °F) above normal.

That’s not an error, or a typo.

The remote research station at Dome C recorded a temperature nearly 40°C above normal for this time of year, beating the previous March record by a startling 20°C. […]

This event is rewriting record books and our expectations about what is possible in Antarctica.

Is this simply a freakishly improbable event, or is it a sign of more to come? Right now, no one knows. […]

Using my standard tools, I make it a 7-sigma event. Really though, that is so unlikely, that it is more natural to assume that this event is simply not from the same distribution as past events. [Which is the definition of “climate change”. –Des] [more]
