At this point does it matter if they find 3000 trillion tons of coal??

Yes.

Its the same thing as realising that there are vast ammounts of deep sea oil in the 1950:s when the technology needed for exploiting it is nearly science fiction.

It makes it very clear that peak oil will not solve the global warming problems and more likely make them even worse.

It gives another degree of freedom for technological development and investment in engineering work to solve our energy needs. We quickly need to discover ways that both are doable and good enough for our environment.
