I think you may have missed my point. The comment I was replying to essentially said, "If we can predict A with little information then we can predict B with little information". My point was that this is not necessarily true and certainly not true in this instance. After all, scientists are frequently wrong about sunspot activity predictions and rarely wrong about where the moon will be at any particular time of the day / year. The comment I responded to also had a needlessly condescending tone to the OP of "Science doesn't work like that...Why not learn a bit about the subject?" which I also objected to.
