Repetitive Watery Excuses

October 1, 2013

If history tells us anything it says that Joanne Nova fails to learn. Her latest attempt to discredit the science is a simple repeat of her past mistakes, only use ocean data to 700 meters, not 2,000 meters, cherry pick your start date and fail to understand how thousands of measurements reduces uncertainty. Let’s examine once again. (more…)

The Ground and Atmosphere are Different

September 19, 2013

The Ground and Atmosphere are Different.

This seems like a fairly obvious statement, but for Joanne Nova it appears difficult for her to grasp. Earlier this year Australia recorded it’s hottest Summer, this has now been followed by our warmest Winter and hottest consecutive 12 months. Nova is furious!


Fingers In Ears

September 3, 2013

With her digits firmly planted in her ears Joanne Nova pretends that AGW is not happening. The science says otherwise. Perhaps Jo is too busy with Tony “It’s crap” Abbott’s political campaign to write about the science, or perhaps it’s just because these climate science papers don’t agree with her preconceived, politically motivated, scientifically-unsupported, blogger opinion? Here’s a small sample of recent peer-reviewed science Joanne wants to wish away.

update: Nova has commented on this list saying “I can rebut most just from their headlines.” … but of course she doesn’t go any further than that and instead yet another person gets “moderated” when the topic becomes too much for Nova. Joanne repetitively points to her “Evidence”, a page which we’ve covered in detail .


Nova – not Hot, not Angry, not Surface Temps

June 29, 2013

Joanne Nova still seems bitter about the fact that Australia had its HOTTEST EVER SUMMER and has tried once again to discredit the temperature record after climate scientists found that humans are increasing the chances of such an event. Nova is repeating an earlier myth so her mistake also repeated (learning can be difficult for some climate denialists).

The UAH temperatures she plots in the graph are atmospheric temperatures, which is not going to be the same as surface temperatures (I am also dubious about how they restrict UAH temperatures to just Australia land). Surface temperatures, as measured by the BOM and reported to the public on a daily basis are NOT the same as the temperature of the atmosphere. This is demonstrated clearly in the graph below.

Over short timeframes, surface temps and atmospheric temps can have large differences.

Since 1979, all surface and atmospheric temperatures show very similar trends.

Nova’s Dryspot

December 7, 2012

Recent research by Fasullo and Trenberth (covered here by SkS) showed that climate models that do a better job at reproducing observations of humidity, are also forecasting a higher sensitivity (greater warming).

Models that better simulate humidity near the infamous hotspot that Nova harps on about, suggest that the warming will be at the higher end of current estimates.

Joanne Nova wants nothing more than to discredit the models, and finds opportunity in John Christy’s blog post. Yeah it’s not peer-reviewed science, of course, but let’s take a look anyway at Christy’s folly.


Carbon dioxide is already absorbing almost all it can – really?

March 8, 2012

On the list of debunked myths that “skeptics” like to promote in an attempt to downplay the significant role of CO2 as a greenhouse gas is the old “More CO2 has little effect” card; Nova’s no exception with her “Carbon dioxide is already absorbing almost all it can” post. This has been debunked many times over. 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.


Monckton – Years later and still no wiser

December 20, 2011

When faced with scientific questions that are beyond my knowledge, I think it better to seek the answer from people with years of knowledge on the subject. Mainstream peer-reviewed science is far more reliable than “web-blogger science” performed by some guy on the internet.

This time Joanne Nova, in search of answers to Venus’ climate has turned to a couple of bloggers and the self-contradicting Monckton.


Gina the Minor

December 12, 2011

Nova suspects governments worldwide are corrupt, secretly working together in order to fool everyone into thinking the planet is warming.

So to prove the climatologists all wrong, here’s the unbiased “science” as described by Australia’s richest person, mining heiress Gina Rinehart.


Nova and Lord – Plumb and Plumber

December 8, 2011

In another befuddled post, Nova looks (I’m not sure this is the right word for what she does) at Sea Levels.

Nova’s science goes from bad to “oh shit I can’t believe she’s really that stupid!!”. Let’s take a quick look.


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.
