Bjorn to Run (Numbers)

The immortal
Bjorn Lomborg takes on a new study claiming global warming will cost 20 percent of global GDP if left unchecked, in
today's Wall Street Journal (free). There's a reason Lomborg is the most famous Skeptical Environmentalist out there--his takedown is very clear, very thorough, calmly rational, and completely devastating:
The Stern review's cornerstone argument for immediate and strong action now is based on the suggestion that doing nothing about climate change costs 20% of GDP now, and doing something only costs 1%. However, this argument hinges on three very problematic assumptions.
First, it assumes that if we act, we will not still have to pay. But this is not so--Mr. Stern actually tells us that his solution is "already associated with significant risks." Second, it requires the cost of action to be as cheap as he tells us--and on this front his numbers are at best overly optimistic. Third, and most importantly, it requires the cost of doing nothing to be a realistic assumption: But the 20% of GDP figure is inflated by an unrealistically pessimistic vision of the 22nd century, and by an extreme and unrealistically low discount rate. According to the background numbers in Mr. Stern's own report, climate change will cost us 0% now and 3% of GDP in 2100, a much more informative number than the 20% now and forever.
Lomborg also reports on another round of 2004's
Copenhagen Consensus experiment, with the same results as last time:
Last weekend in New York, I asked 24 U.N. ambassadors--from nations including China, India and the U.S.--to prioritize the best solutions for the world's greatest challenges, in a project known as Copenhagen Consensus. They looked at what spending money to combat climate change and other major problems could achieve. They found that the world should prioritize the need for better health, nutrition, water, sanitation and education, long before we turn our attention to the costly mitigation of global warning.

Sam-hec, I'll respond to your idea with a question of my own:
Here’s a question for the have-to-do-something-right-now club…
Let say it’s a given that scientists do not fully understand how exactly the climate works. There is a moderate level of understanding, naturally, but a complete understanding of a highly chaotic system and all of its inputs, vectors, etc? No.
Now, let’s compare that to something we do understand and know a good deal about: automobile accidents. We know why they happen, we know how they happen. We understand the physics behind them and can reconstruct them with a high degree of certainty. They are the cause of tens of thousands of deaths every year in the US alone and have a significant economic impact.
I argue that if we really wanted to, we could virtually end car accidents in a short time. It wouldn’t be easy, or cheap, but it could be done: Draconian restrictions on car ownership, mandatory breathalyzers in cars with biometric fail-safes, cameras at every intersection, pop-up tire spikes that activate on red lights at major intersections and all along the road, far heavier penalties for reckless driving, larger (and more vicious) police forces, reactive armor on the outside of cars (for pedestrians, natch), speed governors on all new vehicles preventing exceeding the posted speed limit, GPS tracking and instant speeding tickets, night curfews on driving combined with sleep sensors for those with an approved reason to be driving late at night, radar-linked brake systems, serious jail time for moving violation recidivists, etc.
It would take a decade or so and require a sea-change of culture and behavior. I’m not saying it should be done, but it could be done.
We don’t do all these things now because of an obvious rash of reasons: financial cost, societal upheaval, cost to personal liberty, just to name a few. What we do instead is far more reasonable: mitigate risk as much as possible with better engineered cars, seat belts, air bags, ABS, ESC, etc.
So, a show of hands now: who would say no to ending auto accidents with the scenario above but yes to climate control proposals of the same magnitude?

Okay, since this was brought up earlier in the thread by a couple of folks:
Insurance and Natural Disasters.
Insurance payouts after a natural disaster should not be counted as "losses". Payouts are the product that the insurance industry produces. They are not losses, they are the cost of doing business.
In a truly free market, insurance companies would charge what they felt was an appropriate amount to cover thier losses and still make a profit in the event of a payout. The more expensive the property and riskier the situation, the more your premium would cost. If the risk was too great, they would refuse to insure you and say "Yer on your own kid".
Where the average citizen gets hosed is when the Government gums up those works. In Florida, there is a legislated cap on how much your insurance premium can be, regardless of the risk. What ends up happening is that the insurance companies are faced with hard choices, insure the risky location at a less than reasonable premium or not insure them at all. Prior to the 2004/2005 Hurricane seasons the rationale was, unless the house was in the multimillion dollar range, insure them at the highest price allowed by law since there hadn't been a really bad storm in 10 years. After the 2004/2005 seasons many insurance carriers stopped insuring Florida, a few ended up declaring bankruptcy.
Does this mean that those at high risk are unable to obtain insurance that would make them think twice about building a high cost home right on the beach? The sad answer is no. The state of Florida has a taxpayer backed "Public Insurance" company that "provides insurance to, and serves the needs of, homeowners in high-risk areas and others who cannot find coverage in the open, private insurance market".
About Citizens Property Insurance Corp.
In other words, a carte blanche to build wherever you damn well please because the state assumes your risk.
I am not familiar with other states or countries, but I suspect that many have similar programs.
