Hmm... is Gretta really presenting herself as a scientist? To me the point is she is a young person publicly digesting what a majority of "high profile" scientists are saying about global warming... and wondering why people aren't freaking out? Simple and effective exactly because the long term effects of global warming she's bringing up are really scary to think about.
I'd also say that I do personally wish she was as effective at coming up with answers then a 16 year old instinct to just turn everything off. But it's not just Gretta, as in the age of Twitter, workable solutions are somewhat hard to come by as a general rule. There just aren't enough charcters allowed in a tweet- for anyone to do anything other then bitch.
