On the ABC tonight, Joanne Nova and her husband David Evans appeared on a program, I Can Change Your Mind About Climate, to put forward their argument, that supposedly the planet has not warmed, despite multiple lines of evidence that show it is.
We glimpsed a little of what drives Nova’s political blog, paranoia of all things government-like. Afraid that the ABC would edit and twist her words, Joanne hired her own cameraman to record the interview. Hmmm. Oh well, let’s skip that for now and discuss their “arguments”.
Luckily it won’t take long because we’ve been over them previously.
Urban Heat Island Effect
Nova throws down some photos of some poorly located weather stations and declares that the entire planet’s temperature record is wrong, because of a few examples.
Unfortunately for her, this argument has been done to death, and in the very same program an ex-“skeptic” scientist spoke about the Berkley Earth Surface Temperature study they performed. After a massive amount of reanalysis they found that despite a few poorly sited weather stations, the temperature record, as already reported, was accurate.
As discussed before (cherry picker ahoy), Nova chooses to only use a few years worth of data, not the full amount and she ignores ALL Argo data below 700m because, in her words, “This creates a sudden uptick at the end of the graph”.
Getting rid of data from your chart because you simply don’t like the end result is not good scientific practice.
Paranoid Denialism vs Real Debate
We should be spending our time debating how best to tackle global warming on a global scale. How to transition from polluting sources of energy to cleaner sources; ones that don’t cause long term damage.
Instead Nova jumps at the shadow of ABC debate and thinks it’s completely reasonable to continue repeating old myths.
