The real inconvenient truth is that this theory is not fitting the facts – largest polar ice coverage for years, no increse in sea levels in the Maldives since the 1970s – however, if you programme a computer to show that temperature increase if CO2 levels increase, and then feed in assumptions about increases in CO2 levels, then it is entirley understandable that the computer tells us that temperatures will increase.

Without doubt oil reserves should be conserved – it’s the best portable stre of energy for motorised transport and we should keep it for that purpose. Coal is good for electricty genration, and with FGD is clean, and with CCS meets the requirements of the climate change lobby. However, it is expensive and will probably have little effect.

Claimate change might happen, jsut as it has done many times before when man was not on the planet, but until we can actually understand what is causing it, it seems foolish to disrupt our entire economic capacity for a theory.
