Every once in a while I think we should stand back from the individual trees in the peak oil forest, gave upon the whole thing and pick out the landmarks. To give a sense of where we are and where we're going.
For instance the seizure(takeover? nationalization? whats the correct term?) of fannie and freddie surely marks a historic milestone.
I also the liked the $4 US/gallon landmark - it really seemed to focus the public mind.
I would also note the drop in vehicle miles travelled in the US - previously only done in the oil shocked 70's I believe?
The Iraq war surely merits a mention
9/11 maybe?
I think Bush did a speech where he actually outlined the problem of oil depletion. I dont remember the exact words or dates but its in someone's tagline...
Kunstler on the Colbert report?
Obviously these all vary in magnitude. Any other ideas?
