The world's leading science journal publishing grand claims without verification, in the face of mounting evidence that the claims might be incorrect, is most certainly not "the scientific method".

Actually this is the scientific method. Anything else just makes publishing groundbraking results harder and depends on some people’s (faulty) judgements.
Nature basically publishes the sensational claims papers. That's their model, anything "high impact" goes there. It's then on other scientists to publish work refuting it or proving it's not correct. It's an issue that the refutations tend to go in lower impact journals, but it's the way it's works.

What nonsense. Why would that be infeasible?
