Socrates, Or Pointing The Way For The Future Of Climate Science
Climate science — or at least some parts of it — seems to have devolved into an effort to generate media coverage and talking points for blogs, at the expense of actually adding to our scientific knowledge of the climate system
Actually, it was December 2009 when I wrote in the pages of the Spectator (UK):
This might be the most important lesson of the 1974 report on global cooling: that we need to grow up, separate climatology from fear, and recognise — much as it pains politicians and scientists — that our understanding of how climate changes remains in its infancy.
Here we are, almost two years later. For example, what do we understand about the past? Willis Eschenbach at WUWT shows it in the non-smoothed BEST reconstruction graph:
And what do we understand about the future? Patrick Frank in Skeptic.com’s Reading Room:
In other words: for the past, all we know for sure it’s that the error bars cover from -5C to +3C if we go back to 200 years ago. For the past, all we can estimate for sure it’s that error bars cover an enormous span if we move forward 100 years (even removing cloud uncertainty, still the 2100 error goes from -10C to +16C).
For all we know, Romans were conquering a world that was 50C colder than today, and oceans will boil before the XXII century. Or vice-versa.
Please do not start speculating about uncertainty as a reason for doing nothing – it isn’t.
Think of science instead: what’s the way out of this cul-de-sac made up of giant error bars? How can our understanding finally leave its infancy? The way out has actually being indicated already, by a guy born in 469BC:
Socrates was wise in that he knew the he knew nothing, whereas others were unaware of their own ignorance.
If and when such a realization will become widespread, only then climate science will be able to mature away from silly manipulations, towards the approach so nicely described by Professor Sir Bernard Lovell to David Whitehouse:
One evening we unrolled the pen recorder data in a long ribbon down the corridor outside the main observing room. “Now,” he said, “look at the data. Get to know it.” His point was that before us was what the universe was saying, and that it was more important than any theory.” Data is never inconvenient. It beats theory every time.
An unexamined climate is not worth studying…
