Actually, this is more or less what the scientific community is concluding as well: that only immediate economic forces (ie., insurance rates) will bring people to accept the effects of climate change. The insurance companies are not stupid. They know what’s happening.
The problem is that in places like Bangladesh or sub-Saharan Africa, where the effects of climate change will be quite severe before they are felt here, there is no insurance market and nothing to incentivize investment in adaptation or behavioral change.
