Answer to Question 1

We could discover the problem within a few months using neutrino observatories, which would stop detecting neutrinos from the Sun. However, because it takes nearly a hundred thousand years for energy to travel from the core to the surface of the Sun, it would take approximately the same amount of time for us to start experiencing a cooling of the Sun.
