Jon Snow, climate change, and the nature of science

Channel 4 News tonight gave extensive coverage to the widespread flooding in England, the wettest spell for two hundred years we’re told. The senior news anchor, Jon Snow, was interviewing Andrew McKenzie, a hydrogeologist with the British Geological Survey:

Snow: Answer me the question that everyone keeps asking. Is this caused by climate change?

McKenzie: Well … quite probably.

Snow: I like that answer, but of course it’s not a scientific answer is it?

Aaargh! Obviously we’re getting nowhere in educating the public about science if a leading journalist such as Jon Snow thinks that being uncertain is “unscientific”, when in reality being uncertain is exactly the scientific response to partial and unclear evidence.

Well done to Mr McKenzie for his excellent “quite probably” answer and for explaining that, yes, his answer was indeed scientific:

McKenzie: Well it is a scientific answer. It’s really hard for us to say with certainty that this is down to climate change, but this is the sort of event that we think will happen if we have climate change.

Is this partly due to school science education? School-level science deals almost entirely with known science, stuff that has been worked out and evidence accumulated to the extent that it is certain1, and is quite rightly presented as such. But things are very different at the cutting-edge where partial and unclear evidence is ubiquitous. Are schools failing in teaching what science is actually about, that it is really about attitudes and methods for attaining new knowledge and for dealing with uncertainty?

That which science has already discovered is of huge importance and underpins our whole society, so teaching kids about what we already know is essential, but an appreciation of the nature of the scientific process is also essential for genuine literacy in science.

One could hope that this has improved in the decades since Jon Snow went to school, but in some ways we are going backwards. British science exams nowadays are often about rote learning, about very closely specified mark schemes, and about memorizing the exact word or phrase that the mark scheme requires. Is it too much to hope for school science based on understanding, on problem solving, intellectual exploration and scientific attitudes?

    There are few examples of life from a science education perspective more miserable than being charged with equivocation. Much of that ignoble nonsense comes from the legal sector which places a premium on winning a case according to evidence entered, and once won, dances extravagantly over the efficacy of ‘proof’, as if it had the certainty attached to an ignoramus’s understanding of mathematics. The notion of certitude is a creature of belief, never science. It would be amusing if it wasn’t such an ugly and stultifying disease on society, that the popular view of scientific thinking is so off the mark, considering how much effort and money is invested in ‘public outreach’ campaigns. The worst thing that ever happened to the public perception of science in the recent era was the breathless flurry of activity to promote it utilizing established commercial entertainment equipment largely beginning in the early ’80s, especially following Carl Sagan’s ‘Cosmos’ – an event that had apparently not only underscored how effective popularization can be in the promotion of science, but suggested a means to establish such popularity by recruiting established commercial industry. Despite the constant screeching of having made a difference, quite frankly, the consequences have been dismal: public understanding and support of science is gotten WORSE, not better.

    Pardon, it ‘HAS’ gotten worse.
