Argo Update – David Evans needs new Specs

May 29, 2013

Since our previous post Joanne Nova & David Evans have updated her graphs to include the last six months of data, however they still have more work to do in order to be less deceptive. Jo/David plot the data to 2,000 meters in an odd way by only plotting the 700m-2,000m amount rather than the 0-2,000m amount. They also claim to be ignorant (and I agree) of any model forecast for the ocean down to 2,000 meters. If only they had read just a few more sentences of the paper they cite …

Argo We Go Again

May 24, 2013

I honestly don’t know how Nova can keep a straight face and produce the graphs she does. Once again Joanne Nova posts another example of deceptive graph making.

Not only does she ignore the ocean below 700m meters (because it shows warming), she also chops off the ends to make the graph appear flatter. Firstly, using the same source of information, NODC, let’s take a look at ocean warming from 0 to 2,000 meters.

700 meters – Plus or Minus a Few Months or Years

The Argo flotilla began deployment in 2001. Nova’s first graph posted in 2011 shows data from the start of 2003. Since 2011 the long term warming trend has continued, so Nova now starts the graph midway through 2003 and ends the graph half a year early! That’s right; Nova chops 6 months off the end of the graph. Here’s the full picture …

Nova’s Ocean of Doubt

May 21, 2013

Rather than producing a scientifically supported theory, Joanne Nova raises more “Merchant of Doubt” material based upon a bunch of blogger posts at WUWT and Bob Tisdale (famous for producing Excel graphs supposedly proving everyone wrong, but he won’t/can’t publish because there’s a conspiracy to stop “real science”).

We’ve covered much of what she mentions before, but let’s cover a few new items.

Global Warming Disproved – Has Nova Flipped?

October 3, 2012

Sure Joanne Nova has been under a bit of stress lately, with her website coming under “attack”, (presumably from the feds), but one must wonder what mindset her head is in to declare that she has Disproved Global Warming.

She claims …

The single most important fact, dominating everything else, is that the ocean heat content has barely increased since 2003 (and quite possibly decreased) counter to the simulations.

Yet the latest data from the 3,000+ buoys that form the Argo flotilla provide data to the contrary.

So where does Nova get her concept that the Ocean may have slightly cooled since 2003? Well to obtain a cooling result, first you have to discard any data below 700 meters (Argo data goes to 2,000 meters), then you have to ignore recent years, and then you have to tilt your head to one side and close one of your politically-biased eyes.

The Nova Travesty – Cherry Picker Ahoy!!

December 3, 2011

Joanne “I never cherry pick” Nova takes to the oceans in her quest to yet again cherry pick only the science that supports her political opinion.

This time she blatantly throws out science that has warming in it … because, er, it has warming in it.
