The Soft Science Of Climatology
[…] In earlier years of reporting climate change, news media were regularly accused of attributing any unusual or extreme weather events to climate change – and often the accusations were justified. […]
some scientists have on occasion gone beyond the data in arguing that climate change will bring global catastrophe […]
clearly, highly intelligent, highly educated people can look at the same set of scientific evidence and come to radically different conclusions – not, perhaps, on the basic issue of whether climate change is or isn’t happening, but certainly on what the pace is likely to be and what threat it poses. […]
These are all disparate elements of a complex picture. How do you rate them? Which do you regard as more or less important?
We are back to what you believe; and if Chris Field sees catastrophe in the picture before him, he is entitled to say so, just as Vicky Pope or Mike Hulme are entitled to urge restraint. […]
On this issue of climate understanding as a (personal) belief, I would especially like to quote the last part of Black’s blog:
Individual pieces of research rarely prove anything by themselves […] In the meantime, scientists, politicians and Joe and Joanna Bloggs down the pub are all entitled to give their own assessments, and often there is a fair amount of belief involved, even for the scientists.
To me, there’s little wrong with that. It’s what we do with politics and football and music and film, and I don’t see why climate discourse should be different.
There are facts out there, and we should recognise them as such, just as we should with medicine and social issues and economics; but there is freedom to believe too, and that, the last time I looked, was supposed to be a universal human right.
In other words, Black is saying that climatology is a “soft science”, just as the Social sciences, Economics (and may I dare suggest for personal experience, much of Medicine). He may have even claimed that the “climate discourse” is akin to pub-based football analysis, but personally I really do not want to go in that direction!!
Now, before the usual voices are heard, let me state that I do not consider “soft” to be a demeaning word for a “science”. Of course we would all want to have all sciences as precise and cast-in-stone as Mathematics, and Physics is perhaps the clearest example of what comes closest to the “ideal” concept of a “hard science”.
But there is no point in wasting time in the realm of the impossible: there are areas of knowledge that can only be dealt with in a “soft” manner. As argued by Massimo Pigliucci for “Rationally Speaking“, under the headline “Strong Inference And The Distinction Between Soft And Hard Science” (Jan 27, 2009), perhaps it’s just that the more complex the phenomenon, the more “soft” its science.
Still, if one recognizes Climatology as a “soft science”, then there is absolutely no meaning in oft-repeated claims such as “the science is settled” and “all skeptics are crank, corrupt and/or perverts“. A soft science, by definition, cannot be settled. Its conclusions are ultimately a matter of belief.
