Well, perhaps it escaped your attention that, in a publication loaded
with bright primary colours and infant-school pictures, a major
government origanisation published a graph that said "there are twelve
suspected forcing mechanisms, and we know next to nothing about eight
of them. In the light of this profound lack of knowledge, this other
mechanism is the only one of importance".

If you can't manage to grasp that, then your best is, well, just not
up to it.
