Also: those that have the resources to adjust to climate change ARE NOT the same as those who feel the heaviest weight of the stresses of drought, violent storms, water access, etc. Those with the most resources are also the least likely to be politically instabilized by the effects of climate change.

So you have a mismatch of effort: those who can don't have an incentive to fix the problem for those who can't.

(Or have a counter-incentive: I'm reminded of the anti-monsanto anti-gmo fad in the USA -- despite the fact that GMO foods are our best weapon in producing drought resistant crops for regions most heavily affected by those problems!)
