Whilst there is little danger of the oceans boiling, the website you linked to is hardly worth responding to.
Having no references to peer reviewed work, it is not worth the bother of arguing against it as there are no facts to argue against, no body of work to criticise, just quasi-statistical 'arguements,' and a deliberate misunderstanding of the term 'greenhouse effect' taking up a large portion of the supposed debunking.
Oh, from the same site: DDT - a weapon of survival. Yeah, right - tell that to the thousands of deformed children in Vietnam to whom the US government has yet to issue an apology after dumping tons of the stuff in the form of Agent Orange defoliant during the Vietnam War.
PS - slightly OT aren't we?
