To my mind, people dont see what they dont want to see. It is convenient to to point out such problems as climat change, because if they did, they would need to find a solution, which can be inappropriate to them!
That's one outcome of people "not seeing what they don't want to see."
Another outcome of that is "they would need to find a solution, and so they would generate numerous ill thought out idiocies, and shout that they should be implemented"
