A lot depends on the local circumstances, but watch for the trends over 11-year or longer multi-decadal periods, and it soon becomes apparent if Climate Change is to blame (and thus human burning of fossil fuel).

First, in response to your post, and others, I do believe in man-made climate change.
However, looking at the 11-year trends, one must not only take into consideration climate change in regards to this flooding, but also the decrease in water absorbing land due to development, so it is not so easy just to blame climate change.
It's similar to the current wild fires that have become much more intense over the years here in the USA. Which is more to blame, climate change or the Smoky Bear Effect?
(The Smoky Bear Effect being that since we have been so good, for about a 100 years, at controlling forest fires, that would have happened about once every 20 years naturally, the amount of fuel that has built up in most USA forests is immense. Thus, when a fire finally occurs, it is just that much more intense and destroys everything including old growth trees that would have survived less severe fires.)
These are complicated questions. I am sure both climate change and the other mitigating factors play a role, but which is the bigger evil. Are we ignoring solutions that could bring much more immediate results because we are too focused on climate change as the cause?
