Farmers dont need to be given info on adaptation

Dave Pannell says giving information to farmers on climate adaptation is a waste of time, because

(1) farmers will adapt appropriately to whatever climate change does occur even in the absence of a government program providing advice about it;

(3) the benefits to farmers of providing this sort of information will be minimal.
