For instance, Shackley et al., 1999 surveyed climate modellers about one type of fudge factor, called a «flux adjustment», which was used by many of the climate models in the 1990s.

For this reason, Shackley et al. found that many climate modellers didn't want to talk openly about their adjustments, in case critics of man - made global warming (who they referred to as «climate contrarians») would use them to question the reliability of the models:

But what do climate modellers care for such real - world scientific laws?

To me that's a recipe for chaos, and if you look in any climate modeller's library you will find many books on non-linear dynamics.

Because this is an implicit target for any climate model development and tuning, the selection of such subjective criteria mimics a suite of models, which will be treated by other modellers as suitable for climate studies.

I would be the last one to suggest that there isn't more uncertainty in a system with the internal dynamics of the Earth's climate — and much more scope for severe and rapid change than even the modellers contemplate.

This should, in theory, lead to more realistic projections for the future, but many of the climate modellers I spoke to were keen to point out that simulating the climate with more complex models may well lead to greater uncertainty about what the future holds.
