The Saudi's claim to have sunk a pirate "mother ship" this morning.

However if you think about the more imporant impact, according to the church of the flying spaghetti monster.. The decline of pirates over the years is responsible for global warming and as we have noticed the trend in global warming has slowed down recently along with a re-emergence of pirates.
This should prove the theory correct I'd say because there are clearly more pirates roaming the seas by these news reports and global warming has also declined. Coincidence? I think not.
