text: I'm going to assume (not being an astrophysicist or climatologist,) that there are far more variables relating to climate prediction than to the relative position and extremely regular motions of the Sun, Earth and Moon, since ancient peoples could predict eclipses with some degree of accuracy.   It seems that climate trends have been predicted  -  and are occurring  -  pretty much as expected, but someone who argues about inaccurate daily weather predictions (as has Amy,) is NOT  referring to climate, but to weather.
