I don't recall it being transmitted, but I'll take your word for it.
It was extremely brief (milliseconds) and there weren't any words that I can recall - only a screen shot. It was mentioned at the DP that it was on TV. Perhaps I read too much into it that they actually understood what was happening, but with the later talk of terraforming, and with the involvement of the TV news people these days, I took it that they did indeed know what was going on.

No, I didn't get the impression he'd ever worked in the field either, but that doesn't rule out a degree in journalism (which I'm doubting in this case). If he has a degree, it's likely in something else.
