Being charitable, sometimes the team/org needs to obtain the group learning. If you've had your say, then time will prove you right and people will remember.

If the team/org won't remember AND they just like to rain down decisions on you from above, why you working there...?

In any case communication is HARD. It's always easy to blame people for not listening, but you can't control other people, only yourself. So the most constructive thing to focus on is doing everything in your power to make it clearly and utterly obvious what you can see that no one else can see. That will stay with you and eventually teams will listen to you.
