Richard Betts has kicked off a small Twitter kerfuffle today, taking umbrage at Matt Ridley's Times piece yesterday.
@ProfMarkMaslin Exactly. If @mattwridley wants to criticise climate policy then he's got every right, but attacking scientists is wrong.
— Richard Betts (@richardabetts) December 10, 2014Matt has responded on his own blog today and I'm taking the liberty of reproducing his comment here.
After this article was published an extraordinary series of tweets appeared under the name of Richard Betts, a scientist at the UK Met Office and somebody who is normally polite even when critical. He called me “paranoid and rude” and made a series of assertions about what I had written that were either inaccurate or stretched interpretations to say the least. He then advanced the doctrine that politicians should not criticize civil servants. The particular sentence he objected to was:
Most of the people in charge of collating temperature data are vocal in their views on climate policy, which hardly reassures the rest of us that they leave those prejudices at the laboratory door.
He thought this was an unjustified attack on civil servants. However, if you read what I said in that sentence, it is that (1) people in charge of collating temperature data are vocal in support of certain policies – which is not a criticism, just a statement; and (2) that we need reassurance that they do not let that consciously or unconsciously influence their work, which again is not a criticism, let alone an attack, merely a request for reassurance. Certainly there is no mention of civil servants, let alone by name, and nothing to compare with an attack on me by name calling me paranoid and rude.
Is the first assertion true? I had in mind Jim Hansen, who was in charge of GISS, a data set for which serious questions have been raised about adjustments made that warm the present or cool the past, and who is prepared to get himself arrested in protest against fossil fuels. I also had in mind Phil Jones, partly in charge of HADCRUT, who also is not shy with his views. I was not thinking of Julia Slingo of the Met Office, because I do not think of the Met Office as a collater of temperature data, but perhaps I should have been. And then there’s Australia’s BoM. And indeed the RSS data, whose collater, Dr Carl Mears, fumes at the way “denialists” talk about his data. Hardly objective language.
Is my request for reassurance reasonable? In view of the Australian episodes, the GISS adjustments, the USHCN story from earlier this year (see here) – all of which raised doubts about the legitimacy of adjustments being made to the temperature data – then yes, I think I am. Do I think the data are fatally flawed? No, I don’t. I happily accept that all the data sets show some warming in the 1980s and 1990s and not much since and that this fits with the satellite data. But do I think such data can be used to assert that this is the warmest year, by 0.01 degrees, a month before the year ends? No, I don’t. I think people like Dr Betts should say as much.
As of this writing, Dr Betts’s latest tweet is:
If @mattwridley wants to criticise climate policy then he's got every right, but attacking scientists is wrong.
Well, if by attacking he means physically or verbally abusing, then yes, I agree, but I don’t do it. I don’t call people by name “paranoid”, for example. But criticizing scientists should be allowed surely? And asking for reassurance? Come on, Richard.
The WMO “re-analysed” a data set to get its 0.01 degree warmest year. What was that reanalysis and has it been independently checked? I would genuinely like to know. I stopped taking these things on trust after the hockey stick scandal.
The thrust of my article was that the reputation of the whole of science is at risk if bad practices and biases are allowed to infect data collection and presentation, and that science like other institutions can no longer take public trust for granted. A reaction of bluster and invective hardly reassures me that science takes my point on board. For the moment, I remain of the view that
The overwhelming majority of scientists do excellent, objective work, following the evidence wherever it leads. Science remains (in my view) our most treasured cultural achievement, bar none. Most of its astonishing insights into life, the universe and everything are beyond reproach and beyond compare.
But Dr Betts’s reaction has weakened my confidence in this view.
I must say, this seems a bit out of character for Richard, particularly his retweeting of the "Ridley is wrong because Northern Rock" thing put forward by Mark Maslin (the latter declaring, "North Rock the ultimate failure of neoliberalism", thus rather making Matt's about politicised scientists for him). I always laugh when scientists try to poison the well in this manner. It does so damage their own credibility.
