i love how they try and spin global warming into it as the only way a whale could have made it there. maybe it swam full south and back up along africa. it could happen :)
It also could have swam right through the Suez canal. I've been through that canal, there are no locks. It is one level from start to finish, with absolutely no gates or locks of any kind. IMHO, a whale - if he was curious enough - could easily make that journey and if he was a younger whale, probably without detection.
