Wasting energy on climate change sceptics
By
Greg Jericho It's a pity that climate change scientists have to spend so much time debunking falsehoods - especially when those spouting them have already made their minds up, writes Greg Jericho.This time of the year often brings with it news on climate change. Partly this is because the various agencies recording global temperatures are releasing their annual measures, and partly because invariably we have some pretty hot weather here in Australia.
This year the quirk amidst the usual plethora of reporting and opinion pieces has been the response to
an op-ed by the chair of Tony Abbott's "
Advisory Council", Maurice Newman.
Newman usually pops up on opinion pages or in speeches to variously decry the pay of those on
minimum wage; rail against
wind farms because they are, among other things, "a danger to human health"; or attack climate change.
Now, he's not exactly Robinson Crusoe when it comes to writing about how climate change is all a bit a myth. Heck, it's almost a prerequisite if you wish to get a regular gig excreting your thoughts over the pages of the News Corp dailies.
Of course News Corp's head Rupert Murdoch once said we should "give the planet the benefit of the doubt", but the point of his utterly meaningless phrase is really just to allow his columnists, journalists and editors to repeat it in an attempt to suggest it balances out the avalanche of distorted (or
completely wrong) information which lands on their pages.
It's to be expected though that editors and faux rational opinion writers tackle climate change. After all, they, like those who work for think-tanks such as
the IPA, know it is in their financial interests to deny the science. It's as good for readership as it is good for raising donations from mining companies. And besides, you can't spend all your time pretending you care about free speech.
But when the person writing such ignorant piffle is the head of a select group of people appointed to give advice to the Prime Minister, it does perhaps behove us to treat his muttering as more than just clickbait. If only his opinions were worthy of such treatment.
After all, as Newman makes quite clear, he is "not a climate scientist", and we would all be much better off listening to experts.
The difficulty with responding to such amateur climate-change commentators is you have to parse every sentence for accuracy. For example, Newman starts his argument stating he has "closely followed this debate for more than two decades, having been seasoned originally by the global cooling certainty of the 1970s".
Alas, that "certainty" amounted to
http://journals.ametsoc.org/doi/abs/10.1175/2008BAMS2370.1 10 per cent* of all published scientific articles on climate change from 1956 to 1979. This
compared to 62 per cent of such articles during that period predicting warming, with the rest taking no position.
If he thinks 10 per cent is certainty, I can't wait till Mr Newman discovers the
97 per cent support for global warming that now exists among climate scientists (or the 99.8 per cent support found
in another survey).
But no. We all know that won't sway the "sceptical".
Far better instead to talk about how he really does "believe in climate change" (natural change that is).
The deniers of the science always like to suggest the issue of climate change is too much like a religion - that it's all about "belief". In reality, they are the one most linking religion to the debate - usually by suggesting their opponents are "zealots".
Do I believe in climate change? Sure, in the same way I believe Australia is a better cricket team than England at the moment based on the fact we have beaten the absolute bejeezus out of them in both Tests and one day games this summer. Just because I might use the word "believe" doesn't make my view a religious one.
Newman doesn't rely only on faith either. He notes the "dispassionate" work of Dr Roy Spencer from the University of Alabama at Huntsville (UAH). Unfortunately, Mr Newman neglected to mention that the week before he wrote his piece, Dr Spencer announced the UAH measurement of global temperatures found 2013 was
the fourth hottest year since 1978.
Ahh well. Next year perhaps.
