The other big elephant in the room that those on the Ukrainian side are conveniently ignoring and which sort of fits under the ‘natural’ but unnatural category is the known fact that for a month or two now, Ukraine had begun filling up the Kakhovka reservoir, putting immense pressure on the dam.
If anyone thinks that the Russians blew up the #Kakhovka Dam, and flooded their own positions, making an amphibious assault possible, while cutting off the water supply to #Crimea, seek help immediately. It's curable, but it may take time.
