For the same reason that people aren't sent to jail simply because they are accused of a crime. A scientist who makes a claim, like a prosecutor, must present EVIDENCE of that claim before the claim can be accepted. Until the evidence is presented and properly examined, the idea must remain a hypothesis.
There have been too many claims put forth by scientists that were later shown to be utterly false. Unfortunately, society has a way of remembering the initial claim but forgetting the later refutation. That's why scientists are VERY reluctant to accept a new hypothesis before it has passed rigorous examination.
When it DOES pass the empirical tests, however, the scientist is often richly rewarded.

Yes, global warming is now accepted by the vast majority of climate scientists. It is no longer regarded as a theory but is accepted as true.
it wasnt accepted. Wegener's theory of continetal drift wasnt accepted. the theory of plate tectonics was created when scientists discovered about sea floor spreading and magnetic reversals. but i dont know when the theory of plate tectonics was created. so you can ask about that.
The theory of continental is not accepted as it is been disproved, but it was replaced by the theory plate tectonics. This theory accepted because of may factors including the discovery of mid-ocean ridges, subduction zones, and the tracking of plates via GPS and other means.

It may become a theory.
When it is widely accepted as one.
A scientific theory becomes better accepted as it helps explain more and more observations.
A hypothesis, or group of hypotheses, that is accepted as consistently valid is a theory. Either a hypothesis or a theory can be ultimately disproven. One definition of a theory is an accepted hypothesis.
a theorem rather, it has to be proven to become an accepted theory.

Caralous linnaeus theory is accepted theory of speciation
30 years after he died, and because plate tectronics was intorduced
Douglas Odegard has written: 'Knowledge and scepticism' -- subject(s): Skepticism, Theory of Knowledge
The theory of evolution was accepted by scientists in 1859, Darwin's first book was published the same year that his theory was accepted.
when there s proof to back it up with evidence or an experiment to test the hypothesis
