A big question in my mind is how many years has the planet got left of
fossil fuels (Gas/Oil in particular ?) What ever the figure, surely
assuming we burn the lot, we have then reached the maximum possible
emissions of Co2 output and the scientists nightmare scenario is far
worse than it is now.


There's huge amounts of fossil fuels apart from conventional oil and
gas. There's coal. There's oil shales and tar sands. There's orimulsion.
(I recently saw a statement that the Orinoco Belt, not the Persian Gulf,
has the world's largest oil reserves, which I guess comes down to
whether or not you count orimulsion.) There's methane clathrates. We
might run out of clean and cheap fossil fuels, but we aren't going to
run out of fossil fuels in general in the near future.
