Shoddy, inaccurate, unreliable. Nova’s analysis of BOM temperatures

March 16, 2012

We already know from multiple lines of evidence that the planet is warming, so Nova’s post is yet another “Merchant of Doubt” attempt.

Where did they go wrong this time?

Interestingly in the early 1900’s it was a valid skeptical argument, but it was rebutted and ever since climate scientists knew better.

That doesn’t stop political bloggers from dragging out old myths. Nova goes on to confuse the issue even further.

Nova contradicts herself on many occasions, this time she says the planet IS warming, but that it’s natural thanks to the Akasofu Wave Theory.

Nova says that since 1700 the planet has been warming at a rate of 0.5°C per century. Given that Nova doubts the modern thermometer record, I am surprised to see her have unquestioned faith in reconstructed temperatures. As you can see from this graph of paleoclimate estimates there is a lot of uncertainty about how warm or cold the past was.

Aside from that, the Akasofu Wave Theory has a few problems:
