I address this mostly to this comment's siblings: the fact that you're upset about the lying bit only reinforces labster's point. I say this based on the comments thinking that the lie is actually meant to deceive, getting distracted with the word "lie" and its connotations, and missing the broader issue. The issue is that the general population can't be reasonably expected to understand how climate change works, and how statistics play out in climate change modeling. Unless the message is dead simple, the message will be lost.

What the "lie" "really" says is subtextural/etc: to those that need to hear it, it says what it needs to say to get them to understand what needs to be done (and, importantly, isn't wrong, just isn't the whole picture either); to those that already know the answer, you didn't need to hear the lie in the first place. There is no deceit.

Climate change needs participation from everyone, and, for better or worse, everyone includes a majority of, eh-hem, less-than brilliant people. We need them to understand regardless of our own righteousness.
