Okay, so I read the story there about flooding in Somerset. The article itself is pretty reasonable, but many of the replies to it met the characterization of "only one cause":
"The EA was taken over by environmentalists years ago."
"The UK EA ... was created by Blair to promote the myth of CAGW."
There's no possibility that the lack of dredging is due to budget cutting or a lack of a need for dredging now that the rivers aren't used for barges any more (I don't know if they ever were), it's the AGW proponents who caused it. And there's no possibility that the floods have multiple causes, not just the lack of dredging. For example, places that used to be swamps tend to subside as the water is taken out.
