In today’s Times of London, taking a cue from Blaise Pascal (at least he thinks), Gerard Baker argues, “Unless the sceptics are really, really certain that we’re all going to be OK, we must act now.”
He sums it up this way: “If we believe in global warming and do something about it and it turns out we’re right, then we’re, climatologically speaking, redeemed — if not for ever, at least until some other threat to our existence comes along. If we’re wrong about it, what is the ultimate cost? A world with improved energy efficiency and quite a lot of ugly windmills.”
This is essentially the same argument that Andy Crouch made in an article in Christianity Today in August, 2005, replete with reference to Pascal’s wager.
I responded to Crouch then that “Pascal’s wager is only valid when placed within the context of the eternal and the ultimate. When it is applied to everyday issues, it quickly loses its persuasive power. Crouch’s contention that ‘we have little to lose’ if we exaggerate the threat of global warming displays no recognition of the reality of the future impact of unduly restrictive political policies and environmental regulations.”
You can add Gerard Baker’s contention to Crouch’s, although Baker does note, in agreement with me, I think, that “there is one significant risk that makes this equation slightly different from Pascal’s. There could be high costs of believing in the human role in global warming and being wrong about it. We may have to trade off a lot of economic activity in the next 50 years to lower our carbon emissions.”
Andy and I had more of a back and forth at the time, which are all linked in at this summary piece here.
