I didn't bother reading any of the articles shown in the link to the google search you did, but I don't think I need to. The titles of them all seem to say likely or predicts or could it happen not that it is happening. I suspect you didn't read any of them either and glossed over those points.
Taking the what if scenarios as proof that the storms _are_ getting stronger or more frequent is like believing someone is correct and factual who says what if their magic rock in their pocket prevents them from being attacked by a tiger when they take the subway down town and positing the belief that there _are_ magic rocks that _will_ protect you from the tigers on the subway.
In case I butchered that, the point is that are getting stronger means there is proof it is happening where could be or likely to be or predicted to be is simple asking the question without an answer or predicting it might be without the proof yet of it happening yet.
