However, if Andrew Bolt in the Herald Sun is correct then Gore has been outdone in a big way by Australia's Professor Tim Flannery.
Flannery in 2006 warned we could be on the brink of causing the seas to rise by 25m if we did not slash our emissions.Good question, though again Coba Point isn't all in the danger zone and rises to over 100m according to Google Earth. Unfortunately all of the visible houses, and presumably Tim Flannery's is one of them, are practically on the beach, and beaches tend to be rather close to sea level.
"Picture an eight-storey building by a beach, then imagine waves lapping its roof," he said dramatically.
"So anyone with a coastal view from their bedroom window or kitchen window is likely to lose their house as a result of that change."
So how terrifying it must be for Flannery as he gets his breakfast each morning to look up and see the estuarine waters of the Hawkesbury, just 5m from his waterfront home on Coba Point.
Why hasn't he sold up and moved to higher ground? Is it because even he doesn't believe his absurd scare?
Perhaps Tim's planning on pulling it uphill when the waters get too close.
