focussing on the messaging is a particularly weak way to steer the conversation away from the real issue. just as in your story, that glacier may take an additional decade or two to disappear completely, but it will surely be gone.

we can't seriously believe that if we just adjusted the story a little bit this way or that, that the message would actually click and people would begin to try to minimize the tragic cost to future generations.

this is happening now. blaming the messenger for not being appropriately fawning, or curt, or amusing is kind of irrelevant at this point. maybe we can learn to do a better job next time there is an issue that's going to radically effect everyones lives for the foreseeable future.
