Assume: a) there is a chance that AGW is a reality b) there is a chance of avoiding the most catastrophic effects of AGW as per IPCC recommended action, or even stronger. c) the asset is immeasurably valuable d) there is no other insurance available e) cost of premium is negligible compared to the value of the prospective loss.
Logically, you will be hard pressed to argue against the insurance even if the premium is expensive, and you think the insurance company is not that reliable and may not even agree to pay out the policy.
