I have recently read some remarks that Katrina is not a "peak oil" event. As PG says, of course it is. Demand has never been this high and growing. For that matter, supply has never been this high either. Whether the peak occurs in 2007/08, 2010, 2015 or 2020 as CERA believes, we are on a non-sustainable course in the future. So over this period from now until the peak, there will always be events -- natural or geopolitical or geological -- which will constrain supply and demand. How this plays out economically is really, in the larger sense I am talking about, beside the point. It is short-sited in my view to dismiss Katrina or unrest in Nigeria, for that matter, as unrelated to peak oil.
