Last night’s Horizon programme on BBC TV was entitled ‘Global Weirding’. I had not heard of this term before but, apparently, it was not just dreamt up by the programme producers in a moment of appalling uncreativity.
The negative review of the programme that Andrew Marszal has posted on the Telegraph website (and most of the comments thereon) provides further validation of Dr Tari Sharot’s work on Optimism Bias; about which I and Paul Handover (of Learning from Dogs fame) have both blogged recently.
It is almost incredible that people (I use the term in a very loose sense) can watch a programme like this and yet remain comfortable in their bubble of unreality. Because they (apparently) watched the programme, Cognitive Dissonance does not explain their failure to recognise its significance (i.e. cognitive dissonance sufferers would not have watched the programme). However, Optimism Bias explains their behaviour perfectly. Yes, these people show commendable “bravery” (or is it unwarranted confidence in their rightness of their delusion?) for watching the programme but, nevertheless, the filter they use when watching stuff like this has a sanitising effect that makes a reverse-osmosis water purifier seem like the first phase of a sand and gravel processing plant!
To me, the programme producers seem to have gone to great lengths to avoid being accused of bias or being “alarmist”; and just allowed the data (i.e. collective noun) to tell its own story. Therefore, to continue to believe that the Sun or natural variability is capable of explaining the fact that, for example, Texas can experience record-breaking rainfall and record-breaking drought in consecutive years would appear to be pushing Optimism Bias into the realms of insanity. As if to underline this point, Weatherdem recently posted this characteristically well-executed summary of weather data; demonstrating just how abnormal current weather patterns are in the USA.
Amongst the evidence supporting an anthropogenic cause for the ongoing climatic disruption we are experiencing are the facts that:
– If it were the Sun, the atmosphere would not be warming from the ground upwards; whereas if the warming is being caused by an energy imbalance (i.e. outgoing long-wave radiation being prevented from escaping into Space) this is exactly what you would expect.
– If it were the Sun, the warming would be most obvious in sub-tropical latitudes, whereas if it is energy imbalance the warming will be most pronounced in polar latitudes; exactly what is happening.
Then we have the evidence of solar expert Dr Mike Lockwood who very pointedly conceded that, although blamed for causing the Little Ice Age (1650-1700AD), the Sun is not responsible for the extremely cold UK winters of 2009/10 and 2010/11. On the contrary, the Horizon programme gave a perfectly plausible explanation for what did cause this extreme cold weather (and all the other extremes featured); and also explained how it is that none of this extreme (cold) weather changes the fact that, on average, the world is warming up.
Katharine Hayhoe was seen very clearly making the point that as the Earth has warmed-up, so the average humidity of the atmosphere has increased by 4%. Thus, even though large parts of the USA, UK and Australia may be in drought, when the rain does fall it is likely to be very heavy and, in the meantime, someone somewhere else is undoubtedly getting more than they expected (or probably needed!). Along with warming oceans giving rise to more frequent and more intense storms, increased average humidity is part of a pattern of atmospheric behaviour that was predicted over 20 years ago.
People like me often cite James Hansen’s testimony before US Congress in 1988 as the time since which many humans have been in active denial of the truth. However, the reality of the situation is that the denial started much earlier than that, may be even as early as when President Lyndon Johnson first admitted that we have a problem in 1965. Then there is the case of John Mercer being ridiculed in 1978 for daring to suggest we have a problem (whose treatment James Hansen cited as a reason for widespread scientific reticence in 2007)… Certainly, not much has changed since 1982, when Mike MacCracken was busy telling anyone who would listen (and many would not) that we have a problem.
So, you see, James Hansen did not walk away from the Pioneer Mission to Venus on a mere whim, he took note of what his fellow scientists were telling him and decided that this was something upon which he should focus; and we should be grateful that he did. What we should be somewhat less than grateful for is the orchestrated nature of the campaign to discredit him and many other climate scientists that then arose out of the mendacious work of people like Robert Jastrow, Bill Nierenberg, Frederick Seitz, and Fred Singer… When the Devil was handing out crimes against humanity, they clearly mis-heard him as having been offering “times aspent in true sanity”…
However, compared to this, we should (IMHO) be positively enraged by the fact that the work of these Cold War physicists (with no Communists to fight), has been continued right up to the present day by equally ideologically-blinded experts in ultimately selfish and self-defeating obscurantism such as – yes you guessed it – MIT’s Richard Lindzen; but also the likes of Princeton’s Will Happer. Believe me, if I was seeking a Stalinist revolution, such truth-challenged people (a Barry Bickmore has called them) really would be first on my trains to re-education camps in Siberia (and would thereby count themselves lucky to have avoided the firing squad).
Barry Bickmore is Associate Professor of Geological Sciences at Brigham Young University (Utah, USA). His research specialties are low-temperature geochemistry and geoscience education. In this 40-minute presentation (appended below), he discusses how he moved from being a climate change “sceptic” to being an outspoken advocate of mainstream climate science. He then discusses how it is that people like him can so effectively avoid the truth about climate change. This is the best presentation I have yet seen of all the reasons why so-called climate change “sceptics” are, in point of fact, nothing of the kind… But first, used with permission, here is Barry’s own introduction, as quoted from his own WordPress blog on 11 Nov 2011:
I gave a talk called “How to Avoid the Truth About Climate Change” for the College of Science and Health at Utah Valley University. For those of you who aren’t familiar with me, I am a Republican and a geochemist who, until a few years ago, was quite skeptical about the idea that humans are causing significant climate change.
In the presentation, I briefly talked about how I had made the transition from being a climate change “skeptic” to being an outspoken advocate of mainstream climate science. I then discussed how it is that people like me can so effectively avoid the truth about climate change.
Please pass this video along! I am actually writing a book with the same title, but there’s no way I can get it published before the Republican primaries. Hopefully this kind of thing can influence a few people toward the center on this issue.
