The greening of Al Gore

The Goracle has received a bit of criticism in the press prior to receiving his Nobel Prize.
From the Times Online:

WHO would have thought that saving the planet could be such a lucrative business? Al Gore, the former US vice-president turned environmental campaigner, has made more than £50m in just seven years from his books, speeches and shrewd investments in technology and green ventures.

and from the Daily Mail:

Al Gore is criticised for lining his own pockets after £3,300-per-minute green speech

But at least he's saving the world from CO2 right?
Well, not exactly: Gore Takes Train From Oslo Airport, Luggage Takes Mercedes

Update: scientists in Australia are investigating eco-friendly flatulence.
