May I suggest a more analytical explanation to this kind of behavior ?
1. In industrial risk assessment, we define a simple relation
RiSK = Damage x Probability
To reuse your example, the damage caused by road accident at a busy intersection is mild compared to a nuclear plant explosion with a radioactive cloud. But the probability of occurence of a road accident is high whereas it is minuscule with a nuclear plant meltdown with radioactive leaks. All in all, the RISK in term of casualty is statistically much higher with a busy intersection than with a nuclear plant.
But since people tend to focus on Damage and NOT on Probability, they feel that the risk associated with a nuclear plant is much higher.
2. A second factor to help you prioritize things is the notion of
cost versus benefits (cost in term of risk or $).
- The risk of hemoragy with aspirin is not negligible. But its benefit is high since it relieves and cures many pains so people use it.
- The risk of emitting carbon and upsetting the climate is not nil but the benefits it brings about are huge: just look around you for every usage of fossil fuel which emits carbon but which improve your standard of living and prolong life.
- Using renewable energy may (or may not) "stabilize" the climate but its cost is high: solar, wind or anything renewable kWh costs 3 to 10 times more than the same amount produced by fossil fuel or nuclear.
- Imposing a global emission restriction, including poor countries may (or may not) "stabilize" the climate but the risk of a world economic recession and the resulting cost in the fight against poverty is HUGE.
- Producing local to reduce carbon footprint may (or may not) "stabilize" the climate in a distant future but it causes enormous immediate costs like
this example of African trade hard hit by green measures.
So I think most people who hysterize about GW don't care quantifying things and prioritizing them with simple notions like risks, probability, damage, cost/benefit, least to say unintended consequences, a totally unknown notion to some. They think with their guts, not with their mind. But that's just a theory, not a fact :wink:
